The radius of a right circular cone is increasing at a rate of 4 inches per second and its height is decreasing at a rate of 5 i

solmaris [256]

Answer:

$V' = 900\pi$ $in^{3} /sec$

Step-by-step explanation:

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

$V' = \frac{2\pi rh *r'}{3} + \frac{\pi r^{2} *h'}{3}$ (using differentiation product rule)

plug known values in for r, h, r', and h'

$V' = \frac{2\pi (10)(40)(4)}{3} + \frac{\pi (10^{2} )(-5)}{3}$

$V' = \frac{3200\pi }{3} - \frac{500\pi }{3} \\V' = \frac{2700\pi }{3} \\$

$V' = 900\pi$ $in^{3} /sec$

How do i make (9x-7y=-7) into slope intercept form?

ahrayia [7]

It's called "solve the equation for 'y' ". That means move things
around so that you end up with 'y' all alone on one side, and
everything else on the other side.

You started with 9x - 7y = -7

Subtract 9x from each side: - 7y = -9x - 7

Divide each side by -7 : y = 9/7 x + 1
