Answer:
For this case we have the following quadratic equation:
Where,
t: time
s: height of the ball
By the time the height is 20 feet we have:
Rewriting the polynomial we have:
Using the quadratic formula we have:
Substituting values we have:
Doing the calculations we have the roots are:

Answer:
y = -1½x + 3 11⁄14
Step-by-step explanation:
First convert from <em>Standard Form</em> to <em>Slope-Intercept Form</em>:
2x - 3y = 4
-2x - 2x
____________
-3y = -2x + 4
___ _______
-3 -3
y = ⅔x - 1⅓ >> Slope-Intercept Form
↑
slope
Now, Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>Rate</em><em> </em><em>of</em><em> </em><em>Changes</em><em> </em>[<em>Slopes</em>], so since the slope is ⅔, the opposite multiplicative inverse of that would be -1½, or -3⁄2. Anyway, do the following:
4 = -1½[-⅐] + b
3⁄14
-3⁄14 - 3⁄14
_______________
3 11⁄14 = b
y = -1½x + 3 11⁄14 >> New equation
