The graph of f(t) = 5•2^t shows the value of a rare coin in year t what is the
meaning of the yintercept?

D.

Step-by-step explanation:

The y-intercept is where the graph crosses the y-axis.

It crosses the y-axis at (0,5).

The graph is of f(t)=5*2^t where t is the number of years and the value of f(t) is the value of that coin after t years.

So we have (0,5) is on the graph of f which means f(0)=5.

f(0)=5 means at t=0 years the value of the coin is $5.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

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)
