A ball is thrown from initial height of 2 feet with an initial upward velocity of 35 ft./s. The ball's height H (in feet) after

vodka [1.7K]

So if the height is going to be 20ft, that means 20 = 2+35t-16t²

$\bf 20=2+35t-16t^2\implies 16t^2-35t+18=0
\\\\\\
\textit{now, it doesn't factor in integers, thus}
\\\\\\
 \textit{quadratic formula}\\\\
x= \cfrac{ - {{ b}} \pm \sqrt { {{ b}}^2 -4{{ a}}{{ c}}}}{2{{ a}}}\implies t=\cfrac{-(-35)\pm\sqrt{(-35)^2-4(16)(18)}}{2(16)}
\\\\\\
t=\cfrac{35\pm\sqrt{73}}{32}\implies t\approx
\begin{cases}
1.361\\
0.828
\end{cases}$

Answer:

f(x)=7x+4

When x=-8

f(-8)=7·(-8)+4=-56+4=-52

When x=3

f(3)=7·3+4=21+4=25

When f(x)=67, then :

7x+4=67

7x=63
