Step-by-step explanation:
the sum of all angles in a triangle is always (ALWAYS !) 180°.
180 = 31 + 35 + x = 66 + x
x = 180 - 66 = 114°
\(31\textdegree + 35\textdegree + x \textdegree= 180\textdegree\)
\(66\textdegree + x\textdegree = 180\textdegree\)
\(x\textdegree = 180 \textdegree- 66\textdegree\)
\(x \textdegree= 114\textdegree\)

)(15.0 s−t). At t=0 the object is at x=−14.0 m and has velocity v
0x
=4.20 m/s What is the x-coordinate of the object when t=10.0 s ? Express your answer with the appropriate units.
The object's x-coordinate when t = 10.0 s is -70.5 m.
We are given the following information:
Object's acceleration = a x(t) = -0.0320 m/s³ (15.0 s - t)
At t = 0, object's position = x₀ = -14.0 m
Object's initial velocity = v₀x = 4.20 m/s
We are asked to determine the object's x-coordinate when t = 10.0 s.
To solve for the position of the object as a function of time, we integrate the acceleration twice to obtain the position equation:
x(t) = (1/6)a x(t) t³ + v₀x t + x₀
Integrate acceleration w.r.t. time to get the velocity:
v(t) = (1/4)a x(t) t⁴ - (1/2)v₀x t² + x₀t At t = 0,
we have v₀x = 4.20 m/s.
Hence:
v(0) = (1/4)a x(0) (0)⁴ - (1/2)(4.20 m/s)(0)² + (-14.0 m)
= -14.0 m/s
So the velocity function is:
v(t) = (1/4)a x(t) t⁴ - (1/2)(4.20 m/s) t² - 14.0 m/s
Integrate the velocity function w.r.t. time to get the position function:
x(t) = (1/20)a x(t) t⁵ - (1/6)(4.20 m/s) t³ - 14.0 m t
Since the acceleration function is given as a function of time,
we substitute t = 10.0 s to obtain:
x(10.0 s) = (1/20)(-0.0320 m/s³)(10.0 s)⁵ - (1/6)(4.20 m/s) (10.0 s)³ - 14.0 m (10.0 s)x(10.0 s) = -70.5 m
Hence, the object's x-coordinate when t = 10.0 s is -70.5 m.
Answer: -70.5 m.

817 inhabitants live in a village. Of them, 241 are children.
Of the adults, there are 56 more women than men in the village.
How many men live in the village?
The number of men living in the village is 260.
How do you solve a linear equation system?A collection of many linear equations that include the same variables is referred to as a system of linear equations. A linear equation system is often composed of two or more linear equations with two or more variables.A linear equation with two variables, x and y, has the following general form:
\(ax + by = c\)
Given:
Total inhabitants in the village: 817
Number of children: 241
There are 56 more women than men in the village
Total adults = Total inhabitants - Number of children
Total adults = 817 - 241
Total adults = 576
Let number of men in the village be 'x' and number of women in the village be 'y',
∴ y=x+56 (given) ..................(1)
Also, x+y=576 .................(2)
From equation (1) and (2),
x + (x + 56) = 576
2x + 56 = 576
2x = 576 - 56
2x = 520
x = 520 / 2
x = 260

a basket contains 9 blue ribbons, 7 red ribbons, and 6 white ribbons. what is the probability that three ribbons selected at random will be red?
The probability of selecting three red ribbons at random from the basket is approximately 2.27%.
In order to calculate the probability of selecting three red ribbons from a basket containing 9 blue, 7 red, and 6 white ribbons, we need to use the concept of combinations.
A combination represents the number of ways to choose items from a larger set without considering the order.
First, let's determine the total number of ways to choose 3 ribbons from the 22 ribbons in the basket (9 blue + 7 red + 6 white). This can be calculated using the combination formula: C(n, k) = n! / (k!(n-k)!), where n is the total number of items and k is the number of items to choose. In this case, n = 22 and k = 3. So, C(22, 3) = 22! / (3!(22-3)!) = 22! / (3!19!) = 1540 possible combinations.
Now, let's find the number of ways to choose 3 red ribbons from the 7 red ribbons available. Using the combination formula again, C(7, 3) = 7! / (3!(7-3)!) = 7! / (3!4!) = 35 combinations.
Finally, to calculate the probability of choosing three red ribbons, we'll divide the number of ways to choose 3 red ribbons by the total number of ways to choose any 3 ribbons: Probability = 35/1540 ≈ 0.0227, or approximately 2.27%.

The Nile River in Africa is about 21,832,800ft long. Write an estimate for the length of the Nile river, in feet, as a single digit times an integer power of ten.
Answer:
Step-by-step explanation:
To write an estimate of the length of the Nile River, we can round the number 21,832,800 to the nearest power of ten. The nearest power of ten to 21,832,800 is 10,000,000, which is 107 in scientific notation.
To convert 21,832,800 to scientific notation, we move the decimal point seven places to the left to get 2.18328, and then multiply it by 107 to get:
2.18328 x 107
Rounding this to a single digit times an integer power of ten gives:
2 x 107
Therefore, an estimate for the length of the Nile River, in feet, as a single digit times an integer power of ten, is 2 x 107 feet.

Answer:
A, B, D, E
Step-by-step explanation:
Given expression:
(0.06) · (0.154)When multiplying decimals, multiply as if there are no decimal points:
\(\implies 6 \times 154 = 924\)
Count the number of digits after the decimal in each factor:
0.06 → 2 digits0.154 → 3 digitsTherefore, there is a total of 5 digits.
Put the same number of total digits after the decimal point in the product:
\(\implies (0.06) \cdot (0.154)=0.00924\)
-----------------------------------------------------------------------------------------------
Answer option A
\(\boxed{6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}}\)
When dividing by multiples of 10 (e.g. 10, 100, 1000 etc.), move the decimal point to the left the same number of places as the number of zeros.
Therefore:
6 ÷ 100 = 0.06154 ÷ 1000 = 0.154\(\implies 6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}=(0.06) \cdot (0.154)\)
Therefore, this is a valid answer option.
Answer option B
\(\boxed{6 \cdot 154 \cdot \dfrac{1}{100000}}\)
Multiply the numbers 6 and 154:
\(\implies 6 \times 154 = 924\)
Divide by 100,000 by moving the decimal point to the left 5 places (since 100,000 has 5 zeros).
\(\implies 6 \cdot 154 \cdot \dfrac{1}{100000}=0.00924\)
Therefore, this is a valid answer option.
Answer option C
\(\boxed{6 \cdot (0.1) \cdot 154 \cdot (0.01)}\)
Again, employ the technique of multiplying decimals by first multiplying the numbers 6 and 154:
\(\implies 6 \cdot 154 = 924\)
Count the number of digits after the decimal in each factor:
0.1 → 1 digit0.01 → 2 digitsTherefore, there is a total of 3 digits.
Put the same number of digits after the decimal point in the product:
\(\implies 0.924\)
Therefore, as (0.06) · (0.154) = 0.00924, this answer option does not equal the given expression.
Answer option D
\(\boxed{6 \cdot 154 \cdot (0.00001)}\)
Again, employing the technique of multiplying decimals.
As there are a total of 5 digits after the decimals:
\(\implies 6 \cdot 154 \cdot (0.00001)=0.00924\)
Therefore, this is a valid answer option.
Answer option E
\(\boxed{0.00924}\)
As we have already calculated, (0.06) · (0.154) = 0.00924.
Therefore, this is a valid answer option.

Two parallelograms are similar. The base of the first is 12cm, and its height is 8 cm. Find the base of the second parallelogram if its height is 34 cm.
Answer:
The base of the second parallelogram is 51cm.
Step-by-step explanation:
If the parallelograms are similar, it means by applying the same scale factor to all the sides in one gives you the other. The question tells us the height of the first shape is 8cm and the height of the second shape is 34cm. That means the scale factor is:
\(\frac{34}{8}=4.25\)

A trifle recipe requires 1½ cups of sugar. A chocolate cake recipe requires twice as much sugar. How many cups of sugar go into the cake?___
\( \frac{?}{?} \)
Answer:
The answer is 3, but here’s how I got that answer.
Step-by-step explanation:
As we know the trifle recipe requires 1 ½ cups of sugar, and the chocolate cake requires double the amount of sugar.
You have two options.
Multiply 1½ by 2
1½ x 2 = 3
———————————
Or add 1½ + 1½
1½ + 1½ = 3
———————————-
Wasn’t sure what you were asking for with this this question, but hope it helped.
Answer: 3
Step-by-step explanation:
Since the trifle cake uses 1 ½ cups of sugar and the chocolate twice as much sugar as the trifle cake you should multiply 1 ½ x 2 which would equal 3. So, 3 cups of sugar should go into the cake. (This is my first answer to a question so I'm sorry if I'm confusing)
Find the first derivative for each of the following:
y = 3x2 + 5x + 10
y = 100200x + 7x
y = ln(9x4)
The first derivatives for the given functions are:
For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.
For \(y = 100200x + 7x,\) the first derivative is dy/dx = 100207.
For \(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.
To find the first derivative for each of the given functions, we'll use the power rule, constant rule, and chain rule as needed.
For the function\(y = 3x^2 + 5x + 10:\)
Taking the derivative term by term:
\(d/dx (3x^2) = 6x\)
d/dx (5x) = 5
d/dx (10) = 0
Therefore, the first derivative is:
dy/dx = 6x + 5
For the function y = 100200x + 7x:
Taking the derivative term by term:
d/dx (100200x) = 100200
d/dx (7x) = 7
Therefore, the first derivative is:
dy/dx = 100200 + 7 = 100207
For the function \(y = ln(9x^4):\)
Using the chain rule, the derivative of ln(u) is du/dx divided by u:
dy/dx = (1/u) \(\times\) du/dx
Let's differentiate the function using the chain rule:
\(u = 9x^4\)
\(du/dx = d/dx (9x^4) = 36x^3\)
Now, substitute the values back into the derivative formula:
\(dy/dx = (1/u) \times du/dx = (1/(9x^4)) \times (36x^3) = 36x^3 / (9x^4) = 4/x\)
Therefore, the first derivative is:
dy/dx = 4/x
To summarize:
For \(y = 3x^2 + 5x + 10,\) the first derivative is dy/dx = 6x + 5.
For y = 100200x + 7x, the first derivative is dy/dx = 100207.
For\(y = ln(9x^4),\) the first derivative is dy/dx = 4/x.

three points t, u, and v on the number line have coordinates t, u, and v, respectively. is point t between points u and v ?
We can determine coordinates if point t is between points u and v by checking if u < t < v or v < t < u.
To determine if point t is between points u and v, we need to compare their coordinates. If u < v, then point t is between points u and v if and only if u < t < v. On the other hand, if v < u, then point t is between points u and v if and only if v < t < u.
Whether or not point t is between points u and v depends on the relationship between the coordinates of u and v. If u < v, t must fall between them, and if v < u, t must also fall between them.

Answer:
The values of x for which the function can be replaced by the Taylor polynomial if the error cannot exceed 0.001 is 0 < x < 0.3936.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Determine the values of x for which the function can be replaced by the Taylor polynomial if the error cannot exceed 0.001. f(x) = e^x ≈ 1 + x + x²/2! + x³/3!, x < 0
The explanation of the answer is now provided as follows:
Given:
f(x) = e^x ≈ 1 + x + x²/2! + x³/3!, x < 0 …………….. (1)
\(R_{3}\) = (x) = (e^z /4!)x^4
Since the aim is \(R_{3}\)(x) < 0.001, this implies that:
(e^z /4!)x^4 < 0.0001 ………………………………….. (2)
Multiply both sided of equation (2) by (1), we have:
e^4x^4 < 0.024 ……………………….......……………. (4)
Taking 4th root of both sided of equation (4), we have:
|xe^(z/4) < 0.3936 ……………………..........…………(5)
Dividing both sides of equation (5) by e^(z/4) gives us:
|x| < 0.3936 / e^(z/4) ……………….................…… (6)
In equation (6), when z > 0, e^(z/4) > 1. Therefore, we have:
|x| < 0.3936 -----> 0 < x < 0.3936
Therefore, the values of x for which the function can be replaced by the Taylor polynomial if the error cannot exceed 0.001 is 0 < x < 0.3936.
