H = -16t^2 + 40t + 11

we need to covert this to vertex form

h = -16(t^2 - 2.5t) + 11

= -16 [(t - 1.25)^2 - 1.5625] + 11

= -16(t-1.25)^2 + 25 + 11

= -16(t - 1.25)^2 + 36

The answer is 36 feet

rusak2 [61]

Answer:

<em>2.983 </em>ft/sec

Step-by-step explanation:

Given that

Distance between center and Jasmine riding on a carousal = 9.5 feet

Time taken to complete one rotation = 20 seconds

To find:

Jasmine's linear speed = ?

Solution:

Number of revolutions per minute = $\frac{60}{20} = 3$

Formula for linear speed is given as:

$v=\dfrac{2\pi}{60}\cdot r\cdot RPM$

Where $r$ is the radius of circular path and

$RPM$ is the number of revolutions per minute.

$v=\dfrac{2\pi}{60}\times 9.5 \times 3\\\Rightarrow v=\dfrac{\pi}{10}\times9.5 \\\Rightarrow v = \bold{2.983\ ft/sec}$

Therefore, the linear speed is <em>2.983 ft/sec.</em>

kirza4 [7]

Answer:

The sum of the money shared is $1372

Step-by-step explanation:

The given ratio is

Albert:Michael:Moses=3:5:6

The total ratio is 3+5+6=14

Let the sum of money shared be $x.

Then Albert's share = 3/14 x $x$ = 3 $x$ / 14

Michal's Share = 5x/14

If Michael received $196 more than Albert, then the difference between their share is the $196.

A can of chicken stock measures 3.5 inches in diameter and is 5 inches tall. What is the volume of the can? Use 3.14 for pi. Rou

Margaret [11]

Volume of can, V = pi * r^2 * h
V = 3.14 * (3.5/2)^2 * 5
V = 3.14 * 1.75^2 * 5
V = 3.14 * 3.0625 * 5
V = 48.08125 inches^3
V = 48.08 inches^3
