If f(x) = 4x-x², find<br> square root f(3/2)

katrin [286]

Answer:

$\frac{\sqrt{15} }{2}$

Step-by-step explanation:

$\sqrt{f(\frac{3}{2} )$ , substitute $\frac{3}{2}$ to x

$f(\frac{3}{2} )=4(\frac{3}{2} )-(\frac{3}{2} )^2$ = $\frac{15}{4}$ or 3.75

$\sqrt{f(\frac{3}{2} )$ = $\sqrt{3.75}$ = $\frac{\sqrt{15} }{2}$

kirza4 [7]

A negative times a negative is a positive so...

( - ) ( - ) ( - ) ( -10x ) = -5

10x = -5

x = -5/10

A volleyball reaches its maximum height of 13 feet, 3 seconds after its served. Which of the following quadratics could model th

julsineya [31]

Only selections B and D give a maximum height of 13 at t=3. However, both of those functions have the height be -5 at t=0, meaning the ball was served from 5 ft below ground. This does not seem like an appropriate model.

We suspect ...
• the "correct" answers are probably B and D
• whoever wrote the problem wasn't paying attention.
