The size, s, of a tumor (in cubic millimeters) is given by s=2^t, where t is the number of months since the tumor was discovered. give units with your answers.

(a) what is the total change in the size of the tumor during the first 9 months?

the total change is
and its units = .

(b) what is the average rate of change in the size of the tumor during the first 9 months?

the average rate of change is

,
and its units = .

(c) use an interval of 0.001 to approximate the rate of change at which the tumor is growing at t=9.

the rate is

,

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

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)
