Answer:

The answer is option B.

Explanation:

A rule that uniquely associates elements of one set A with the elements of another set B and each element in set A maps to only one element in set B.

Each element from X is related to only one element in Y. But it is okay for two different elements in X to be related to the same element in Y. So its  still a function. Let suppose

{ (1,a) , (2, b) , (2, c) , (3, d) }

This relation is not a function from X to Y because the element 2 in X is related to two different elements, b and c.

Given the equation:

We will find the intercepts of the given equation.

The x-intercept is the value of (x) when y = 0

So, substitute with y = 0 and solve the equation to find (x)

So, the x-intercept = -2

The y-intercept is the value of (y) when x = 0

So, substitute with x = 0 and solve the equation to find (y):

So, the y-intercept = 2

Step-by-step explanation:

The curve joining the points P1, P2, P3, and so on is called the involute of a circle.

To construct the locus of the free end of the coir for unwinding through an angle of 360 degrees, as well as the normal and tangent at any point on the curve.

Here are the steps for construction:

1. Draw a line PQ that is tangent to the circle and is equal to the circumference of the circle. This line represents the coir being unwound.

2. Divide both the circle and the tangent line into the same number of equal parts. Label these divisions on the circle as 1, 2, 3, and so on. Similarly, label the divisions on the tangent line as 1', 2', 3', and so on.

3. Draw tangents at points 1, 2, 3, and so on on the circle. Mark the points where these tangents intersect the tangent line as P1, P2, P3, and so on.

The distance from each point Pi to the corresponding point i' on the tangent line should be the same as the distance from the center of the circle to the point i on the circle.

4. The curve joining the points P1, P2, P3, and so on is called the involute of a circle. This curve represents the locus of the free end of the coir as it unwinds.

The process involves creating an initial circle that represents the drum, then using this to draw a horizontal line that's the same length as your first circle's circumference. Divide both into segments and draw lines (tangents) from one set of segments to the other. Points along these lines represent an unwound thread and create the involute when joined up. Tangents and normals can also be drawn onto this curve.

This question pertains to the mathematical concept of a curve locus, specifically the spiral curve produced by unwinding a coir from a drum. To draw this spiral curve (or 'involute'), start by sketching a circle representing the drum (with diameter 30mm). Next, calculate the circumference of this circle and draw a horizontal line of equivalent length. Then, divide this line and the circumference of your circle into the same number of equal sections. For each section in your circle, draw a line from the point of division to an equivalent point on your horizontal line. These lines are your tangents. Mark points on these lines which correspond to the distances covered by the unwound thread. Finally, join these points to create the involute of the circle.

For the part about drawing a normal and a tangent at any point on the curve: Pick a point on the curve. Remember that the tangent at a point on an involute is perpendicular to the line from the point to the centre of the original circle. A normal at any point on a curve is simply a line drawn perpendicular to the tangent at that point.

Answer: She has 21 lira coins.

Step-by-step explanation:

Given, Laura collects old foreign coins. She has 83 coins in total. She has 53 lira and drachma coins. She has 51 lira and peseta coins.

Let x = the number of lira coins.

y= the number of drachma coins.

z= the number of peseta coins.

Then, as per given, we have

x+y+z=83   (i)

x+y=53   (ii)

x+z=51   (iii)

From (ii) and (iii)

y=53-x

z=51-x

Put these values in (i) , we get

x+(53-x)+(51-x)=83

⇒ x+53-x+51-x=83

⇒ 104-x=83

⇒104-83=x

⇒x= 21

Hence, she has 21 lira coins.

The interquartile range (IQR) is a measure of the spread or variability of the middle 50 percent of the data.

The interquartile range (IQR) is a statistical measure that describes the spread or dispersion of the middle 50 percent of the data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset.

The quartiles divide a dataset into four equal parts, each representing 25 percent of the data. The first quartile (Q1) represents the lower boundary of the middle 50 percent, while the third quartile (Q3) represents the upper boundary of the middle 50 percent. The IQR captures the range of values within this middle range.

By focusing on the middle 50 percent of the data and excluding the extreme values, the interquartile range provides a measure of variability that is less affected by outliers or extreme values. It is commonly used in descriptive statistics and data analysis to understand the spread and distribution of a dataset, particularly when the data is not symmetrically distributed or contains outliers.

The correct options are:

1) the triangle is isosceles.

2) the leg-to-hypotenuse ratio is 1:√2  

3) the non-right angles are congruent.

4) the ladder represents the longest length in the triangle.

For given question,

the length of the ladder is 12 feet.

the distance from the wall to the base of the ladder is 6√2 feet

Let x be the height of the wall.

Using Pythagoras theorem,

⇒ x² + (6√2)² = 12²

⇒ x² = 72

⇒ x = 8.5 ft

So, the triangle is right triangle.

Here, the hypotenuse = 12 ft

And, the leg-to-hypotenuse ratio is,

6√2 : 12 = 1:√2

Therefore, the can of beans that is the best deal is option b, which has the lowest price per unit volume.

Volume is a measure of the amount of space occupied by an object or a substance. It is often measured in cubic units such as cubic centimeters, cubic inches, or cubic meters. The formula for finding the volume of different objects may vary based on their shape and size, but it typically involves measuring the length, width, and height of the object and multiplying them together.

Here,

To determine which can of beans is the better deal, we need to compare their volumes and prices per unit volume.

The volume of the small can of beans is:

V₁ = πr₁²h₁

= π*(1)²*(3)

= 3π

The price per unit volume of the small can is:

P₁ = $1.49 / 3π

≈ $0.157 per cubic inch

For the other cans of beans, we can calculate their volumes and prices per unit volume:

a. V₂ = πr₂²h₂

= π*(3)²*(9)

= 81π

P₂ = $39.95 / 81π

≈ $0.155 per cubic inch

b. V₃ = πr₃²h₃

= π*(2)²*(3)

= 12π

P₃ = $5.96 / 12π

≈ $0.132 per cubic inch

c. V₄ = πr₄²h₄

= π*(3)²*(3)

To calculate the salary in the sixth year, we need to apply the annual increase of 6% to the initial salary of $32,000 for five consecutive years.

Year 1: $32,000

Year 2: $32,000 + 6% increase = $32,000 + (0.06 * $32,000) = $32,000 + $1,920 = $33,920

Year 3: $33,920 + 6% increase = $33,920 + (0.06 * $33,920) = $33,920 + $2,035.2 = $35,955.20

Year 4: $35,955.20 + 6% increase = $35,955.20 + (0.06 * $35,955.20) = $35,955.20 + $2,157.31 = $38,112.51

Year 5: $38,112.51 + 6% increase = $38,112.51 + (0.06 * $38,112.51) = $38,112.51 + $2,286.75 = $40,399.26

Year 6: $40,399.26 + 6% increase = $40,399.26 + (0.06 * $40,399.26) = $40,399.26 + $2,423.95 = $42,823.21

Therefore, the salary in the sixth year is approximately $42,823.

Total Salary = $32,000 + $33,920 + $35,955.20 + $38,112.51 + $40,399.26 + $42,823.21

Total Salary ≈ $223,210

The total salary paid over the six-year period is approximately $223,210.

Answer:

do you have a equation to go with x?

Step-by-step explanation:

Given:

Principal value = 1200

Rate of interest = 7% per annum

Time = 3 years

To find:

The simple interest for three years.

Solution:

The formula for simple interest is:

\(S.I.=\dfrac{P\times r\times t}{100}\)

Where, P is the principal value, r is the rate of interest in percentage and t is time in years.

Putting \(P=1200,r=7,t=3\) in the above formula, we get

\(S.I.=\dfrac{1200\times 7\times 3}{100}\)

\(S.I.=12\times 7\times 3\)

\(S.I.=252\)

Therefore, the simple interest for three years is 252.

The equation of line t, which is perpendicular to line s and passes through (-2, 9), is y = -3x + 3 in slope-intercept form.

Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. The slope of line s, given by the equation y = (1/3)x - 5, is 1/3. Therefore, the slope of line t must be -3, which is the negative reciprocal of 1/3.

To find the equation of line t, we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is a point on the line.

We are given that line t passes through the point (-2, 9) and has a slope of -3. Substituting these values into the point-slope form, we get:

y - 9 = -3(x - (-2))

Simplifying the expression on the right side and rearranging, we get:

y - 9 = -3x - 6

Adding 9 to both sides, we get:

y = -3x + 3

Therefore, the equation of line t in slope-intercept form is y = -3x + 3, where the slope is -3 and the y-intercept is 3.

The absolute maximum and  minimum value of f(x) on the interval [-7, 16] is 2.358, -2.358 at x = 8 and x = -8

To find the absolute maximum and absolute minimum values of the function \(f(x) = x*e^{(-x^2/128)}\) on the interval [-7, 16], we need to look for the critical points and the endpoints of the interval.

First, let's find the critical points by taking the derivative of f(x) and setting it equal to zero:

\(f(x) = x*e^{(-x^2/128)}\)

\(f'(x) = e^{(-x^2/128)} - (x^2/64)*e^{(-x^2/128)}\)

Setting f'(x) equal to zero, we get:

\(e^{(-x^2/128)} - (x^2/64)e^{(-x^2/128)} = 0\)

\(e^{(-x^2/128)(1 - x^2/64) }= 0\)

So either\(e^{(-x^2/128)} = 0\) (which has no solutions), or\(1 - x^2/64 = 0\), which gives us x = ±8.

Next, we need to check the endpoints of the interval:

\(f(-7) = -7e^{(-49/128)} \approx -0.091\)

\(f(16) = 16e^{(-256/128)} \approx 0.090\)

Now we can compare the values of f(x) at the critical points and endpoints to find the absolute maximum and absolute minimum values:

f(-7) ≈ -0.091

\(f(8) = 8e^{(-64/128)} \approx 2.358\)

\(f(-8) = -8e^{(-64/128)} \approx -2.358\)

f(16) ≈ 0.090

So the absolute maximum value of f(x) on the interval [-7, 16] is approximately 2.358, and it occurs at x = 8.

The absolute minimum value of f(x) on the interval [-7, 16] is approximately -2.358, and it occurs at x = -8.
