Answer: It is not
Explanation:
Fourth root 5x^5
(Fourth root 5x)^5
= fourth root 3125x^5
12.9
Diameter is just the radius times 2
I'm doing the exact same one an i got 48 cubic units for the volume. I still have to draw the rectangular figure though.
The answer would be 93 cents divide it by 2 since you want to share with someone and you would have 46 cents and a nickel for both people
Answer:
The correct option is;
21 ft
Step-by-step explanation:
The equation of the parabolic arc is as follows;
y = a(x - h)² + k
Where the height is 25 ft and the span is 40 ft, the coordinates of the vertex (h, k) is then (20, 25)
We therefore have;
y = a(x - 20)² + 25
Whereby the parabola starts from the origin (0, 0), we have;
0 = a(0 - 20)² + 25
0 = 20²a + 25 → 0 = 400·a + 25
∴a = -25/400 = -1/16
The equation of the parabola is therefore;

To find the height 8 ft from the center, where the center is at x = 20 we have 8 ft from center = x = 20 - 8 = 12 or x = 20 + 8 = 28
Therefore, plugging the value of x = 12 or 28 in the equation for the parabola gives;
