Answer:
<u>The correct answer is C. A(x) = 480/x +2x²</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the problem correctly:
Volume of a rectangular prism with square base = 120 cubic feet
Side of the square base = x
Height of the prism = h
2. Write the surface area of the prism as a function A(x) of the length of the side of the square x.
Let's find out A(x) this way:
Volume of a rectangular prism with square base = 120 cubic feet
x² * h = 120
h = 120/x²
Now, let's substitute h in the surface area formula, this way:
Surface area = 2 * side of the square base² + 4 * side of the square base * height
A(x) = 2x² + 4x * 120/x² (Recall 120/x² = h and side of the square = x)
A(x) = 2x² + 480x/x²
<u>A(x) = 2x² + 480/x </u>
<u>The correct answer is C. A(x) = 480/x +2x²</u>
1, 2, 4, 5, 10 & 20
The greatest common factor is 20.
Answer:
central angle = 360/24 = 15°
arc length = 15/360 * 2π * 15 = 1.25π = 3.93 feet.
Area of a sector = 15/360 * π * (15)^2 = 9.375π = 29.45 square feet
Hope This Helps! Have A Nice Day!!
