A ball is thrown from an initial height of 2 feet with an initial upward velocity of 18/fts . The ball's height h (in feet) afte

inna [77]

Hello! First insert 6 where the h is located. So we have an equation that looks like the following. $6 = 2 - 18t + 16t^2$

Although you could leave the equation in its original form, I am going to switch it around.
$6 = 2 - 18t + 16t^2$
$16t^2 - 18t + 2 = 6$
Move the 6 to the other side and do the math
$16t^2 - 18t + 2 - 6 = 6 - 6$
$16t^2 - 18t -4 = 0$
Factor and after factoring your T will be as follows
t = $\frac{9}{16} - \frac{\sqrt{145}}{16}$ = -0.1900
t = $\frac{9}{16} + \frac{\sqrt{145}}{16}$ = 1.315

The area of the right triangle shown is 24 square feet.

Liula [17]

Answer:

A, 0.5(x)(x+2)=24, D, x²+2x-48=0, and E, x²+(x+2)²=100

Step-by-step explanation:

A and D are correct because they simply involve the Area of a Triangle formula. A has the formula in the same format, but D has the 0.5 divided from by both sides.

E, on the other hand, uses the Pythagorean theorem to solve for both legs.
