In the equation cd = -56, find the value of d if c = 4.
Answer:
-14
Step-by-step explanation:
CD= -56
C=4
D= CD/C
= -56/4
= -14
Hello there!
cd=-56.
We are given that
c=4
We can plug it into the equation instead of c:
4d=-56
Now we must divide both sides by 4 in order to isolate d:
d=-14
Remember that whatever we do to one side, we do to the other.

Two angles are complementary the difference between four times the measure of the smaller angle and the measure of the larger angle is 10 what is the measure of the larger angle
The measure of the larger angle is obtained as follows:
70º
What are complementary angles?Two angles are defined as complementary is the sum of their measures is of 90º.
The variables that represent each angle in this problem are given as follows:
x and y.
They are complementary angles, hence:
x + y = 90.
The difference between four times the measure of the smaller angle and the measure of the larger angle is 10, hence:
4y - x = 10.
x = 4y - 10.
Hence the value of y is obtained as follows:
4y - 10 + y = 90
5y = 100
y = 100/5
y = 20º.
Hence the measure of the larger angle is given as follows:
x + 20 = 90
x = 70º.

the graph of a certain geometric sequence can be described as a curve increasing from left to right. which sequence would have a similar graph?
The graph of a certain geometric sequence can be described as a curve increasing from left to right. A sequence that would have a similar graph is the geometric sequence whose common ratio is less than 1.
A geometric sequence is defined as a sequence of numbers where each number is the product of the previous number and a fixed constant. The fixed constant is known as the common ratio, and it is denoted by r.The nth term of a geometric sequence is given by the formula an= ar^(n-1) where a is the first term and r is the common ratio of the sequence.
Similar graphIn a similar graph, the shape of the graph is the same, but the size may be different. Thus, the sequence that would have a similar graph to the given sequence is a geometric sequence whose common ratio is less than 1 because in such a sequence, the successive terms will be smaller than the previous term.This means that as we move from left to right, the values will gradually decrease in size, and the graph will look like a curve increasing from left to right.

Use differentials to approximate the change in cost corresponding to an increase in sales (or production) of one unit. Then compare this with the actual change in cost. (Round your answers to two decimal places.) Function x-Value C = 0.075x2 + 6x + 7 X = 10 dollars dc = AC = dollars
Comparing with the estimated change in cost using differentials (dc = 7.5 dollars), we can see that the estimate is significantly larger than the actual change in cost.
We can use the differential of the function to approximate the change in cost (C) corresponding to an increase in sales (or production) of one unit (dx). The differential of the function C = 0.075x² + 6x + 7 is given by:
dC = (d/dx) (0.075x² + 6x + 7) dx
dC = (0.15x + 6) dx
At x = 10 dollars (which represents the initial sales or production level), we have:
dC = (0.15*10 + 6) dx = 7.5 dx
Therefore, an increase in sales or production of one unit (dx = 1) would lead to an approximate increase in cost of:
dc ≈ dC = 7.5 dollars
To find the actual change in cost (AC), we can calculate the cost at x = 11 dollars and subtract the cost at x = 10 dollars. This gives:
C(11) - C(10) = (0.07511² + 611 + 7) - (0.07510² + 610 + 7)
C(11) - C(10) ≈ 21.85 - 19.25 = 2.60 dollars
Comparing this with the estimated change in cost using differentials (dc = 7.5 dollars), we can see that the estimate is significantly larger than the actual change in cost. This is because the differential approximation assumes that the function is changing linearly at x = 10, whereas the actual function may be changing at a different rate.
However, the differential approximation can still provide a useful estimate of the change in cost for small changes in sales or production levels.

A distribution is a way of displaying data, consisting of three primary components: shape, center, and spread. The shape is the overall pattern of the distribution, while the center is the point where the distribution is balanced. The spread is the range of values of the data, often measured by the standard deviation or the interquartile range (IQR). The distribution can be visualized through graphs like histograms, box plots, or scatter plots.
A brief description of a distribution should include its shape, center, and spread. The spread is the term that should be included in the blank space.A distribution can be described as a way of displaying data. It gives us an idea about how the data are spread out.
The three primary components of any distribution are the shape, center, and spread. Shape refers to the overall pattern of the distribution. It tells us whether the data are symmetric or skewed. The symmetry means that the left half of the distribution is a mirror image of the right half, whereas a skewed distribution is not symmetrical. The tail of a distribution describes the spread of a skewed distribution. It refers to the parts of the distribution that extend out from the center of the graph.The center refers to the point where the distribution is balanced. In symmetric distributions, the center is the same as the mean and median. However, in a skewed distribution, the mean and median differ from each other.
The spread refers to the range of values of the data. It tells us how much the data are scattered or spread out. A small spread indicates that the data points are close to each other, while a large spread suggests that the data points are far from each other. It is often measured by the standard deviation or the interquartile range (IQR).The distribution of data can be visualized through different graphs like histograms, box plots, or scatter plots.

is y=24/x direct, inverse, or joint variation
The equation y = 24/x is an inverse variation.
The equation y = 24/x shows an inverse variation between y and x.In mathematics, direct variation is a relationship between two variables where one variable is proportional to the other variable. That is, when one variable increases, the other variable also increases in proportion to the first variable. Direct variation is expressed mathematically as y = kx, where k is the constant of proportionality and x and y are the variables being compared.Inverse variation, on the other hand, is a relationship between two variables where one variable decreases in proportion to the other variable as the other variable increases. Inverse variation is expressed mathematically as y = k/x, where k is the constant of proportionality and x and y are the variables being compared.Joint variation, also known as combined variation, is a relationship between three or more variables where one variable is directly proportional to one or more variables and inversely proportional to one or more other variables. Joint variation is expressed mathematically as y = kxz, where k is the constant of proportionality and x, y, and z are the variables being compared.Based on the given equation, y = 24/x, it is clear that y is inversely proportional to x. This is because as x increases, y decreases in proportion to the increase in x. Similarly, as x decreases, y increases in proportion to the decrease in x.

Describe the zero product property and explain how tu use it to solve (2x + 10) (x - 7) = 0
Answer:
See below
Step-by-step explanation:
Basically, when you have a product to two factors set equal to 0, you can use the Zero Product Property and make two separate equations, both set equal to 0, to find the roots for each factor:
\(2x+10=0\\2x=-10\\x=-5\)
\(x-7=0\\x=7\)
Notice that by plugging these roots back into the equation, either factor will be 0, making the whole expression 0:
\((2x+10)(x-7)=0\\(2(7)+10)(7-7)=0\\(24)(0)=0\\0=0\)
\((2x+10)(x-7)=0\\(2(-5)+10)(-5-7)=0\\(0)(-12)=0\\0=0\)

Area:
Shape a: 3*3=9
Shape b: 3*5=15
Shape c: 10*3=30
30+15+9=54
Area is 54
Step-by-step explanation:
The perimeter of a shape is all the outside measurements of its sides rogether. So, add all the sides.
\(3 + 3 + 2 + 3 + 3 + 3+ 10 + 3 + 3 + 6 \\ = 39\)
So 39 is your perimeter.
As for the area, you could do this in many ways since this shape can be cut up into all sorts of smaller shapes, but I'm assuming you mean surface area. To get that, take the area of all the shapes there are in this one and then add them all together. I added an attachment of the areas I'm going to take. I separated the shape into three different ones.
These are all rectangles, and the area for a rectangle is lw.
So...
\(lw + lw + lw\)
^This will be the formula to use for the area. Keep in mind, these are all different areas separately, so you do not combine the like terms (as tempting as it may be).
Now just substitute: 3×3 3×5 3×10
\((3 \times 3) + (5 \times 3) + (10 \times 3) \\ 9 + 15 + 30 \\ 54\)
So 54 is your area.

5. Find the Fourier coefficients of the periodic ( -5 to 5) function y(t) = -3 when -5
In summary, the Fourier coefficients for the periodic function y(t) = -3 on the interval -5 ≤ t ≤ 5 are:
c₀ = -3 (DC component)
cₙ = 0 for n ≠ 0 (other coefficients)
To find the Fourier coefficients of the periodic function y(t) = -3 on the interval -5 ≤ t ≤ 5, we can use the formula for Fourier series coefficients:
cn = (1/T) ∫[t₀-T/2, t₀+T/2] y(t) \(e^{(-i2\pi nt/T)}\) dt
where T is the period of the function and n is an integer.
In this case, the function y(t) is constant, y(t) = -3, and the period is T = 10 (since the interval -5 ≤ t ≤ 5 spans 10 units).
To find the Fourier coefficient c₀ (corresponding to the DC component or the average value of the function), we use the formula:
c₀ = (1/T) ∫[-T/2, T/2] y(t) dt
Substituting the given values:
c₀ = (1/10) ∫[-5, 5] (-3) dt
= (-3/10) \([t]_{-5}^{5}\)
= (-3/10) [5 - (-5)]
= (-3/10) [10]
= -3
Therefore, the DC component (c₀) of the Fourier series of y(t) is -3.
For the other coefficients (cₙ where n ≠ 0), we can calculate them using the formula:
cₙ = (1/T) ∫[-T/2, T/2] y(t)\(e^{(-i2\pi nt/T) }\)dt
Since y(t) is constant, the integral becomes:
cₙ = (1/T) ∫[-T/2, T/2] (-3) \(e^{(-i2\pi nt/T)}\) dt
= (-3/T) ∫[-T/2, T/2] \(e^{(-i2\pi nt/T)}\) dt
The integral of e^(-i2πnt/T) over the interval [-T/2, T/2] evaluates to 0 when n ≠ 0. This is because the exponential function oscillates and integrates to zero over a symmetric interval.
all the coefficients cₙ for n ≠ 0 are zero.

After Julia has driven for a quarter of an hour, she was 170 miles east from Denver. After driving for 3 hours, she was only 100 miles east from Denver. Assume that Julia drove at a constant speed during the trip. Let be a function that gives Julia's position east from Denver (measured in miles) after having driven for hours. a) Determine a rule for the function . b) Interpret the meaning of (16) and then find its value if it exists. c) Interpret the meaning of (-141) and then find its value if it exists. d) Determine a rule for e) Construct a graph for .
(a) The rule for the function is = -280/11 + 187.27, (b) Julia is 409.09 miles west of Denver after having driven for 16 hours, (c) Julia cannot have a negative amount of time, (d) the rule is = 11/280 - 187.27/280 and (e) to construct a graph for , plot the two points (0.25, 170) and (3, 100) and draw a line between them
a) The rule for the function can be determined by finding the slope of the line between the two points (0.25, 170) and (3, 100). The slope is (100-170)/(3-0.25) = -280/11.
Therefore, the rule for the function is = -280/11 + b. To find b, plug in one of the points: 170 = -280/11(0.25) + b. Solving for b gives b = 187.27. Therefore, the rule for the function is = -280/11 + 187.27.
b) The meaning of (16) is Julia's position east from Denver after having driven for 16 hours. To find its value, plug in 16 for in the rule: (16) = -280/11(16) + 187.27 = -409.09. Therefore, Julia is 409.09 miles west of Denver after having driven for 16 hours.
c) The meaning of (-141) is Julia's position east from Denver before she started driving, which does not exist because she cannot have a negative amount of time.
d) To determine a rule, we need to find the inverse of the function. The inverse of a function is found by switching the and variables and solving. So, the inverse = -280/11 + 187.27 becomes = -280/11 + 187.27. Solving it gives = ( + 187.27)/(280/11) = 11/280 - 187.27/280. Therefore, the rule for is = 11/280 - 187.27/280.
e) To construct a graph, the two points (0.25, 170) and (3, 100) and draw a line between them. The slope of the line is -280/11 and the y-intercept is 187.27.

A circle can be defined as a geometric shape consisting of all points in a plane that are equidistant from a given point, which is known as the center. The distance between the center of the circle and any point on the circle is referred to as the radius.
In order to find the center and radius of a circle, we need to have three points on the circle's circumference, and then we can use algebraic formulas to solve for the center and radius. Let's look at the given problem to find the center and radius of the circle that passes through the points (-1,5), (5,-3), and (6,4).
Center of the circle can be determined using the formula:
(x,y)=(−x1−x2−x3/3,−y1−y2−y3/3)(x,y)=(−x1−x2−x3/3,−y1−y2−y3/3)
Let's plug in the values of the given points and simplify:
(x,y)=(−(−1)−5−6/3,−5+3+4/3)=(2,2/3)
Next, we need to find the radius of the circle. We can use the distance formula to find the distance between any of the three given points and the center of the circle:
Distance between (-1,5) and (2,2/3) =√(x2−x1)2+(y2−y1)2=(2+1)2+(2/3−5)2=√10.111

Answer: The most likely reasoning for Adnan's belief is (C) Art, music, and writing require creativity and outside-the-box thinking, whereas math does not.
This answer choice suggests that Adnan believes that his job as a creative writing teacher is similar to the job of an art or music teacher because they all involve fostering creativity and encouraging students to think creatively. In contrast, Adnan believes that the job of a math teacher does not require this type of creative thinking.
The other answer choices do not provide a strong rationale for Adnan's belief. While it is true that art, music, and writing can be taught in a way that is open-ended and allows for creative interpretation, this is not necessarily the main reason why Adnan believes his job is similar to those of art and music teachers. Similarly, while it is true that some students may choose to enroll in art, music, or writing classes out of passion, this is not necessarily the main reason why Adnan believes his job is different from that of a math teacher. The requirements for becoming an art, music, or writing teacher may also be less strict, but this is not necessarily the main reason why Adnan believes his job is different from that of a math teacher.

Suppose that 63 of work is needed to stretch a spring from its natural length of 30 cm to a length of 40 cm. (a) How much work is needed to stretch the spring from 34 cm to 38 cm? (Round your answer to two decimal places.)
0.96 (b) How far beyond its natural length will a force of 10 N keep the spring stretched? (Round your answer one decimal place.) 0.8 cm
The spring is stretched by 0.8 cm beyond its natural length, rounded to one decimal place.
Given that a work of 63 is needed to stretch a spring from its natural length of 30 cm to a length of 40 cm.
(a) To find out how much work is needed to stretch the spring from 34 cm to 38 cm, we have to apply the concept of work done by spring, which is given as below:
Work Done by Spring= (1/2)k(x^2 - x₁²)
where k is the spring constant, x is the final stretched length, and x₁ is the initial length.
We can find the spring constant using the formula as below:
k = (F/x)where F is the applied force and x is the change in length.
Using the above formulas, we can get the solution as follows:
Given that, x₁ = 34 cm, x = 38 cm.
So, x - x₁ = 38 - 34 = 4 cm.k = (F/x) ⇒ 10 = F/4 ⇒ F = 40 N.
Now, k = (F/x) = (40/4) = 10 N/cm.
Now, Work done by spring = (1/2)k(x^2 - x₁²)
⇒ Work done by spring = (1/2) × 10 × (38^2 - 34^2)
⇒ Work done by spring = 0.96 Joule
Therefore, the work needed to stretch the spring from 34 cm to 38 cm is 0.96 Joule, rounded to two decimal places.(b) To find out how far beyond its natural length will a force of 10 N keep the spring stretched, we can apply the following formula as:
W = (1/2)kx²where W is the work done on the spring and x is the distance the spring is stretched beyond its natural length.So, x = √(2W/k)
where W = 10 N, k = 10 N/cm.
Using the above formula, we can get the solution as follows:x = √[(2×10)/10] = √2 = 1.41 cm
Now, the spring is stretched by 1.41 - 0.3 = 1.11 cm beyond its natural length.
Therefore, the spring is stretched by 0.8 cm beyond its natural length, rounded to one decimal place.
