Hello : let  A(2,55)    B(4,91)<span>
the slope is :   (YB - YA)/(XB -XA)
(91-55)/(4-2)  = 36/2 =18
an equation is : y-55 = 18(x-2)</span>

<span> y-intercept when : x = 0  :  y - 55 = 18(0-2)
y-55 = -36
y = 55-36 = 19</span>

olga2289 [7]

Answer:

The radius of the balloon is increasing at a rate of 4 feet per minute.

Step-by-step explanation:

We are given the following in the question:

\dfrac{dV}{dt} = 64\pi \dfrac{\text{ ft}^3}{\text{min}}

Volume of sphere is given by

V = \dfrac{4}{3}\pi r^3

where r is the radius of the balloon.

Instant radius, r = 2 ft

Rate of change of volume =

\dfrac{dV}{dt} = \dfrac{d}{dt}(\dfrac{4}{3}\pi r^3)\\\\\dfrac{dV}{dt} =4\pi r^2\dfrac{dr}{dt}

Putting values, we get,

64\pi = 4\pi (2)^2\dfrac{dr}{dt}\\\\\Rightarrow \dfrac{dr}{dt} = 4

Thus, the radius of the balloon is increasing at a rate of 4 feet per minute.

Step-by-step explanation:

First find the angle of QUR

QUS is 90 so you just subtract 45 from 90 and you get 45

QUP is also 90. Add 45 to it this time: 135
