7. Which is the function that describes the table below?

The value of (n o p) (Δ) is X.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

(n o p) (Δ):

= n ( p(Δ) )

From the function map we have,

p(x) = (Δ, Y)

This means,

For x = Δ we get p(Δ) = Y.

So,
= n ( Y )

From the function map we have,

n(x) = (Y, X)

This means,

For x = Y we get n(Y) = X

So,

= X

Thus,

Using the function map,

(n o p) (Δ) is X.

The population of the town in 1982 is 29995.2.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given, the population in 2020 is 49992.

40 percentage of population

= 40 % of 49992

= 40 x 49992/100

= 19996.8

Now the population in 1982

= population in 2020 - 40% of population in 1982

= 49992 - 19996.8

= 29995.2

Therefore the population in 1982 is 29995.2.

Correct choice is C.

Assuming that the football field is a perfect rectangle, we will see that its area is 5,500 square yards.

We assume that the football field has a rectangular shape. Remember that for a rectangle of length L and width W the area is given by the formula below.

A = L*W

In this case, we know that the dimensions of the football field are:

L = 100 yards

W = 55 yards.

Then we just need to replace these values in the area formula that is written above, we will get:

A=  (100 yd)*(55 yd)

A = 5,500 yd²

The area of that football field is 5,500 yd², so the correct option is the second one.

The value of angle P = 119°

The value of angle Q = 61°

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the value of angle P be = P

Let the value of angle Q = Q

Now , the equation will be

Measure of angle P is three less than twice the measure of angle Q

Substituting the values in the equation , we get

P = 2Q - 3   be equation (1)

And , angle P and angle Q are supplementary

So ,

P + Q = 180°   be equation (2)

Substituting the value of P from equation (2) in equation (1) , we get

2Q - 3 + Q = 180

On simplifying the equation , we get

3Q - 3 = 180

Adding 3 on both sides of the equation , we get

3Q = 183

Divide by 3 on both sides of the equation , we get

Q = 61°

Therefore , the value of Q is 61°

Substitute the value of Q in equation (2) , we get

P + Q = 180°

Subtracting Q on both sides of the equation , we get

P = 180° - 61°

P = 119°

The measure of angle P = 119°

Hence , The value of angle P = 119°

The value of angle Q = 61°

Answer:

[tex]D) y=-\frac{1}{2} x-4[/tex]

Step-by-step explanation:

Perpendicular means the slope of the other line is the negative reciprocal.

Slope in y = 2x - 5 is 2.

Negative reciprocal of 2 is - 1/2 or - 0.5

y = - 0.5x + b

Substitute.

- 5 = - 0.5(2) + b

- 5 = - 1 + b

b = - 4

The perimeter of octagon A is 40 inches.

Perimeter is the sum of all the sides of a figure.

Since, both of them are octagons, we will simply use unitary method to calculate the perimeter of octagon A.

2.5 ---> 4

x -----> 64

cross multiplying gives,

Answer:

Step-by-step explanation:

If cakes of 4 small and 4 large tiers serve 288 guests, and 3 small and 5 large tiers serve 316 guests, you want to know the number of guests served by a tier of each size.

Let 's' and 'l' represent the numbers of guests served by small and large cake tiers, respectively. The first cake serves ...

  4s +4l = 288

And the second cake serves ...

  3s +5l = 316

Subtracting 3/4 of the first equation from the second gives ...

  (3x +5l) -3/4(4s +4l) = (316) -3/4(288)

  2l = 100

  l = 50

  4s +4(50) = 288 . . . substitute for l in the first equation

  4s = 88 . . . . . . . . . . subtract 200

  s = 22 . . . . . . . divide by 4

A small tier will serve 22 guests; a large tier will serve 50 guests.

Answer: length=6 feet

Step-by-step explanation:

For this you need to create one equation from the question and use the equation for perimeter.

equation 1 is     2W+2L=P   where perimeter is 43.

equation 2 is w=3L-2.5

-Now you want to take equation two and plug it into equation 1 for w to find L

It will be  2(3L-2.5)+2L=43 and you want to solve for L

distribute the 2   2(3L-2.5)+2L=43

add up the Ls      6L-5+2L=43

add 5 to each side    8L-5=43

divide each side by    8L=48

Then you get L=6

Now use L=6 to plug into equation two to get W(width)

w=3(6)-2.5=18-2.5=15.5

Now plug in both W and L into equation 1 to make sure you get 43

P=2(15.5)+2(6)=32+12=43 this means that w and l are correct and you get the perimeter given. So length (L) is 6.

This is False in light of the stated statement. due to the employment of a regression line to calculate the mean of y for x that are outside the x-range of the data.

Y = mX + b, where X is the predictive (independent) factor, m is really the approx slope, and b is the expected intercept, is the methodology for simple linear regression.

Regress, from whence the word "regression" is derived, means "to go back" in Latin (to something). Regression is the method that enables "going back" from muddled, challenging data to a clearer and more significant model in this manner.

The coordinates of A'B'C'D' are A'(2, 1), B'(3, 1), C'(3, -1) and

D'(2, -1).

What is translation of points?

By describing how far a point is moved left, right, and up or down, translations are defined.

If we know which way and how far the figure should be moved, we can draw the translation in the coordinate plane. Use P'(x + a, y + b) to translate the point P(x, y) to the right and up, respectively, by a and b units.

For the given graph, the coordinates of ABCD are,

A(-2, 3)

B(-1, 3)

C(-1, 1)

D(-2, 1)

The translation is, (x, y) → (x + 4), y - 2)

So, the coordinates of A'B'C'D' are,

A(-2, 3) → A'(2, 1)

B(-1, 3) → B'(3, 1)

C(-1, 1) → C'(3, -1)

D(-2, 1) → D'(2, -1)

The graph of translation is attached below.

Hence, the coordinates of A'B'C'D' are A'(2, 1), B'(3, 1), C'(3, -1) and

D'(2, -1).
