Claire keeps track of the miles per gallon her car gets per week. she has accumulated the following data:

(1, 22.42), (2, 22.84), (3, 23.26), (4, 23.68)

what is the common difference or ratio?

the common ratio is 0.99.
the common ratio is 1.02.
the common difference is 0.42.
the common difference is 0.84.

Step-by-step explanation:

subtract week one from week two and find the difference, they should all be that number which is your common difference.  

23.68

-23.26

    .42

22.84 - 22.42 = .42

23.26 - 22.84 = .42

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)

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
