Hello!
The length and width are given.
We know the formula for calculating perimeter :
Let's solve!
- Perimeter = 2(123 + 17k + 24k - 49)
- Perimeter = 2(41k + 74)
∴ The perimeter is 82k + 148.
Given:
h(t) = 25 - a·t²
h(0.5) = 21
Find:
t such that h(t) = 0
Solution:
h(0.5) = 25 - a·0.5² = 21
25 - 21 = a/4
4·4 = a = 16
Then
h(t) = 25 - 16t²
We want h(t) = 0, so
0 = 25 - 16t²
16t² = 25
t² = 25/16 = (5/4)²
t = 5/4 = 1.25
It takes 1.25 seconds for the entire 25 ft drop.
