A ball is dropped from a 75 foot tall tower, and the height of the ball (in feet) can be represented by the equation h = —16t^2
damaskus [11]

Answer:

The ball will take approximately 2.165 seconds.

Step-by-step explanation:

The height of the ball is represented by the function h(t) = -16\cdot t^{2}+75, the time taken by the ball to hit the ground is a value of t such that h(t) = 0, we proceed to solve the following equation for t:

-16\cdot t^{2}+75 = 0 (1)

16\cdot t^{2} = 75

t = \sqrt{\frac{75}{16} }

t \approx 2.165\,s

The ball will take approximately 2.165 seconds.

A round mirror has a circumference of 87.92 inches. Calculate the area of the mirror.
Zarrin [17]

\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ C=87.92 \end{cases}\implies 87.92=2\pi r\implies \cfrac{87.92}{2\pi }=\boxed{r} \\\\[-0.35em] ~\dotfill\\\\ \textit{area of a circle}\\\\ A=\pi r^2~\hspace{7em}A=\pi \left( \boxed{\frac{87.92}{2\pi }} \right)^2 \\\\\\ A=\pi \cdot \cfrac{87.92^2}{4\pi^2}\implies A=\cfrac{87.92^2}{4\pi }\implies A\approx 615.127998

If 11^-x=4, what does 11^2x equal
max2010maxim [7]

Answer:

0.0625

Step-by-step explanation:

11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
