I got it! Each function (x=) is solved separately. First is x= -4. You take that and replace all x's with -4. If the "if x..." is true you use the function in front to solve. In this case the x_<-4 is true for -4 equaling x. The function is front is x^2. So substitute the x for -4 and solve. -4^2 is 16.   Next you have the other one x=4. The function that goes with this one is the last one, substitute x for 4 and your answer is 2. The answers are 16 and 2. I hope this helps!

LiRa [457]
Okay, so when dealing with unit rates you want to see how much you have of your main measurement. In this case your main measurement is ounces. Since you have 16 and 32 you are going to divide your dollar amount by those and round to the nearest tenth. 
Here are the equations that need to be used. Figure out the answers to them and round. This will give you your answer
3.98/16=

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
