Answer:c
Step-by-step explanation:
The shape of the window is a trapezoid, and the area of the window is 110.88 square feet
<h3>How to determine the area of the window?</h3>
The given parameters are:
- Long base = 15.2 feet
- Short base = 11.2 feet
- Perpendicular height = 8.4 feet
The shape of the window is a trapezoid.
So, the area is:
Area = 0.5 * (Long + Short) * Height
This gives
Area = 0.5 * (15.2 + 11.2) * 8.4
Evaluate
Area = 110.88
Hence, the area of the window is 110.88 square feet

Answer:
(0, 1)
(7.1, 0.49)
Step-by-step explanation:
The graph of the function is attached below.
We have an exponential function:
And we have a quadratic function:
To find the solution to:
we must look in the graph for the values of x for which both curves are intercepted, these values are:
Then the solution are the following ordered pairs:
(0, 1)
(7.1, 0.49)
Answer:
The last one
Step-by-step explanation:
when you are dividing an equation with exponents, you subtract the exponents from each other.
For example, in your problem you have d^4 and d^2 (notice that they have the same base) you subtract the exponents to get d^2
** even if the bases are numbers, you DONT touch the base, just the exponents ( ex.: 5^4 ÷ 5^3 = 5^1)
Do this w/ the rest of the exponents.
d^4 ÷ d^2 = d^2
e^3÷e^2= e
f^5÷f= f^4
** although f looks like it doesn't have an exponent, it has an invisible one
And w/ the power of deduction, you should get -2/3 d^2ef^4
Answer:
L = 22 ft
Step-by-step explanation:
Let L and W represent the length and width respectively.
L = 4W, or W = L/4. Use W = L/4 because we want to solve for W, not for L.
Area of a rectangle: A = L · W
Here, A = L · L/4 = 121 ft²
Mult. both terms by 4 removes the fraction:
L² = 484
Finding the square root of this result: L = 22
The length of the rect. is 22 ft.
