The amount of building material needed to cover the pyramid which Tony's architecture firm is constructing is 144 square feet.
What is area of triangle?The area of the triangle is half of the product of base and height of the triangle. It can be calculated as,
[tex]A=\dfrac{1}{2}b\times h[/tex]
Here, b is the length of base, and h is the height.
Tony's architecture firm is constructing a square pyramid play structure for a school.
The length of one side of the base will be 9 feet, Each face is a triangle with a height of 8 feet. The pyramid will be open at the bottom and not covered.As the height of the triangle is 8 and base is 9 feet of triangle. Thus, the area of one triangular face is,
[tex]A=\dfrac{1}{2}\times9\times8\\A=36\rm\; ft^2[/tex]
Area of 4 triangle side is,
[tex]A=36\times4\\A=144\rm\; ft^2[/tex]

An expression is shown below:
2x3 + 10x2 − 4x2y − 20xy
Part A: Rewrite the expression so the GCF is factored completely.
Answers
The given expression can be rewritten as 2x(x²+5x-xy-10y).
The given expression is 2x³+10x²-2x²y-20xy.
What is GCF?GCF stands for the greatest common factor. The greatest common factor of two numbers is the greatest number that is a factor of both of them.
Now, 2x³=2×x×x×x, 10x²=2×5×x×x, 2x²y=2×x×x×y and 20xy=2×x×x×y
Here, the GCF of all the terms is 2x.
So, the expression becomes 2x(x²+5x-xy-10y).
Therefore, the given expression can be rewritten as 2x(x²+5x-xy-10y).

1. The graph of y = f(x) is a parabola whose vertex is at (1, -2). The graph of y = f(x - 3) is also a parabola. Where is the vertex of the graph of y = f(x-3)? Write your answer as an ordered pair.
2. The graph of has the line as an axis of symmetry. The graph also passes through the point. Find another point that must lie on the graph of y = f(x).
3. The graph of y = f(x) is shown in the first picture in red. Find the equation that corresponds to the blue graph.
Enter your answer in the form "y = …".
4. The graph of y = h(x) is shown in red in the second picture. Compute h(h(7)).
(Assume grid lines are spaced 1 unit apart.)
5. In the third picture is a portion of the graph of a function, y=u(x):
What is the exact value of u(-2.72)+u(-0.81)+u(0.81)+u(2.72)?
Answers
Answer:
Q1The graph of y = f(x), has vertex at (1, -2)
The vertex of a function f(x - 3) is going to be:
(1 - 3, -2) = (-2, -2)Q2The graph of y = f(x) has the line x = 5 as an axis of symmetry. The graph also passes through the point (8,-7). Find another point that must lie on the graph of y = f(x).The axis of symmetry is at the same distance from the symmetric points.
x = 5 is a vertical line. The point (8, -7) is 3 units to the right. So the mirror point will be 3 units to the left and have same y-coordinate: x = 5 - 3 = 2
The point is (2, -7)
Q3The graph in blue is the translation of the red to the left by 2 units.
So the equation is:
y = f(x + 2)Q4y = h(x) is graphed
h(7) = 5h(h(7)) = h(5) = -1Q5The graph of the function y = u(x) given
This is a odd function.
The coordinates of u(x) and u(-x) add to zero because u(-x) = -u(x)
Therefore:
u(-2.72) + u(-0.81) + u(0.81) + u(2.72) = [u(-2.72) + u(2.72)] + [u(-0.81) + u(0.81)] = 0 + 0 = 0Need help plz this is math. Don’t answer if you don’t know. I will give brainliest to the right answer.

81 is 18% of what number?
Enter your answer in the box.
Answers
Answer:
450
Step-by-step explanation:
Formula = Number x 100
Percent = 81 x 100
18 = 450
Following shows the steps on how to derive this formula
Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.
81
18% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
18Y = 81 x 100
18Y = 8100
Y = 8100
100 = 450
Answer:
450
Step-by-step explanation:
18% of 450 is 81. 100% of 450 is 450, therefore 18 percent of 450 equals 81. To learn how to solve 81 is 18 percent of what Number, see the step by step instructions below.
