5b= -G+ 1/5 UA Solve for a:

enot [183]

Answer:

switch sides

-g+2/5UA=5b

add g to both sides

-g+1/5UA+g=5b+g

simplify

1/5UA=5b+g

multiply both side by 5

5×1/5UA=5×5b+g

simplify

AU=25b+5g

divide both sides by U

AU/U=25b/u+5g/u =U/U=0

simplify

A=25b+5g/U

Sofia hits a softball straight up. the equation h= -16t^2 + 90t models the height h, in feet, of the ball after t seconds. How l

andrezito [222]

It is in the air 5.625 seconds.

Using the quadratic formula,

$t=\frac{-b\pm \sqrt{b^2-4ac}}{2a}
\\
\\=\frac{-90\pm \sqrt{90^2-4(-16)(0)}}{2(-16)}
\\
\\=\frac{-90\pm \sqrt{8100-0}}{-32}
\\
\\=\frac{-90\pm \sqrt{8100}}{-32}=\frac{-90\pm90}{-32}
\\
\\=\frac{-90+90}{-32}\text{ or }\frac{-90-90}{-32}=\frac{0}{32}\text{ or }\frac{-180}{-32}
\\
\\=0\text{ or }5.625$

0 is when the ball is first launched, 5.625 is when it hits the ground again.
