The radius of a cone is decreasing at a constant rate of 7 inches per second, and the volume is decreasing at a rate of 948 cubi
nadezda [96]

Answer:

Step-by-step explanation:

We have volume of cone as

V=\frac{1}{3} \pi r^2 h

and for a cone always r/h = constant

Given that r' = rate of change of radius = -7 inches/sec

(Negative sign because decresing)

V' =- 948 in^3/sec

Radius = 99 inches and volume = 525 inches

Height at this instant = \frac{525}{\frac{1}{3} \pi (99)^2} \\=\frac{0.1607}{\pi}

Let us differentiate the volume equation with respect to t using product rule

V=\frac{1}{3} \pi r^2 h\\V' = \frac{1}{3} \pi[2rhr'+r^2 h']\\-948 = \frac{1}{3} \pi[2(99)(-7)(\frac{0.1607}{\pi})+99^2 h']\\

-948 = \frac{1}{3} \pi[2(99)(-7)(\frac{0.1607}{\pi})+99^2 h']\\-948 = 33(3.14)(-2.25/3.14  + 99 h')\\-9.149=-0.72+99h'\\-8.429 = 99h'\\h' = 0.08514

Rate of change of height = 0.08514 in/sec

- 2y + 3 = - 4y<br> The solution set is what???
lianna [129]

Answer:

Y=-3/2

Step-by-step explanation:

-2y+3=-4y

Move constant to the right  by adding its opposite to both sides

-2y+3-3=-4y-3

Eliminate the opposites

-2y=-4y-3

collect the like terms

-2y+4y

collect the like terms

(-2+4)y

Calculate the sum

2y=-3

divide both sides of the equation by 2

2y÷2=-3÷2

Any expression divided by itself equal 1

y=-3÷2

y=-3/2
