The value of (n o p) (Δ) is X.
What is a function?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,

Thus,
Using the function map,
(n o p) (Δ) is X.

Which of the follow is the equation of a line perpendicular to y=2x-5 that passes through the point (2, -5)?
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
y = - 0.5x - 4
13 Two sides of a triangle are 27 inches and 17 inches. What are the possible lengths of the third side? Give your answer as an inequality.
______
The third side of the triangle will be lies between 10 and 44
The rule that we will use to answer this is:
The sum of lengths of two sides of a triangle must be more than the length of the third side.
So, we have side lengths 27 and 17. 27 + 17 = 44 and thus the third side must be less than 44.
Now to consider how small it can be. If we represent the third side as X, we can get 17 + X > 44 which gives us X > 27
Therefore the third side is between, but not including, 10 and 44 units long.

parenta=-1, h=k=0a=1, h=0, k=5a=1, h=5, k=-12a=-1, h=-5, k=-12Step-by-step explanation:
Given several transformed functions, you want to identify the parameters of the transformation: a, h, k.
TransformationWe assume your transformation of the function g(x) has the pattern ...
y = a·g(x -h) +k
You are trying to match the given functions with this pattern.
Here, 'a' is the multiplier of the absolute value function. In these examples, it is 1 or -1.
The parameter 'h' is the value subtracted from x inside the absolute value bars. (This is the amount of translation of the graph to the right.)
The parameter 'k' is the value added to the (scaled) absolute value, the constant on the right outside the absolute value bars. (This is the amount of translation of the graph upward.
parent: a=1, h=k=0a=-1, h=k=0a=1, h=0, k=5a=1, h=5, k=-12a=-1, h=-5, k=-12__
Additional comment
We have used g(x) as the function name, instead of the more usual f(x). This is because Brainly squawks any expression where f(x) is multiplied by 'a'.
Once you have identified the parent function, the pattern matching process can begin. The value of 'a' multiplies the function. The value of 'k' is added to the function. The value 'h' is subtracted from x where x is inserted into the parent function.
If the parent function is y = (3x²+2), then h=1 would give y = (3(x-1)²+2). The value of 'a' would multiply this expression, and the value of 'k' would be added to this expression.
Graph the translation and identify the coordinates of the image
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

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°

Find the area of a football field that is 100 yards long and 55 yards wide.

510 yds2
5100 yds2
Assuming that the football field is a perfect rectangle, we will see that its area is 5,500 square yards.
How to find the area of the football field?
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

Destiny owns a cake shop and she is working on two wedding cakes this week. The first cake consists of 4 small tiers and 4 large tiers, which will serve a total of 288 guests. The second one includes 3 small tiers and 5 large tiers, which is enough servings for 316 guests. How many guests does each size of tier serve?
A small tier will serve guests and a large tier will serve guests.
Answer:
small tier: 22large tier: 50Step-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.
SetupLet '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
SolutionSubtracting 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.
