Answer:
See below in bold.
Step-by-step explanation:
(-3)^3(2^6)/(-3)^5(2)^2
= (-3)^(3-5)*(2^4)
= 2^4 / (-3)^2 so a = 4 and b = 2.
2^4 / (-3)^2
= 16/9 so c = 16 and d = 9.
Answer:
what do you mean
Step-by-step explanation:
A^2 + b^2 = hypotenuse ^2
2^2 + 6^2 = h^2
4+36=h^2
40=h^2
h= square root of 40
The c value would be 40 (within the root)
For my work I got
A I hope it’s not wrong
![h(x) = 40x - 16x^2\\h(x) = 15\\40x - 16x^2 = 15\\-16x^2 + 40x - 15 = 0\\](https://tex.z-dn.net/?f=h%28x%29%20%3D%2040x%20-%2016x%5E2%5C%5Ch%28x%29%20%3D%2015%5C%5C40x%20-%2016x%5E2%20%3D%2015%5C%5C-16x%5E2%20%2B%2040x%20-%2015%20%3D%200%5C%5C)
Using the quadratic formula we get
![x_1 = 0.5\\x_2 = 2.04](https://tex.z-dn.net/?f=x_1%20%3D%200.5%5C%5Cx_2%20%3D%202.04)
Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds
