Answer:

\frac{1}{15} x

Step-by-step explanation:

\frac{7x}{20}  -  \frac{5x}{12}

\frac{3 \times 7x}{3 \times 20}  -  \frac{5 \times 5x}{5 \times 12}

\frac{21x}{60}  -  \frac{25x}{60}

\frac{21x - 25x}{60}  = (21 - 25)x =  - 4x

\frac{ - 4x}{60}  =  -  \frac{ x}{15}

\boxed{\green{=  \frac{1}{15} x}}

P=2×22/7×13

P=81.71in.

If it will make 3 revolution then it will have move 3 times it perimeter

A ball is thrown into the air with an upward velocity of 28 ft/s. its height,h, in feet after t seconds is given by the function
ddd [48]

<span>h= (-16t^2 + 28t + 7)  </span>

find the derivative to get time<span>
<span>
h' = (-32t + 28)

When the ball reaches its maximum height, its vertical velocity (h’) will be 0 </span></span>

<span>
<span> 0 = -32t + 28 </span></span>

-32t=-28

<span><span>-28/-32 =  </span>0.875 seconds </span><span>
<span>
The ball reaches its maximum height in 0.875 seconds after being thrown; plug and chug and:

h= (-16(0.875)^2 + 28(0.875) + 7) = 19.25 feet</span></span>

 

Max height = 19.25 feet, time = 0.88 seconds
