The marginal price for a weekly demand of x bottles of shampoo in a drugstore is given by the function shown below. Find the price-demand equation if the weekly demand is 150 when the price of a bottle of shampoo is $8. What is the weekly demand when the price is $4.50?

p'(x) = -6,000/(3x + 50)^2

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
