Acircle has a center at left-parenthesis 3 comma 5 right-parenthesis. the point left-parenthesis 3 comma 8 right-parenthesis is on the circle. what is the circumference of the circle to the nearest tenth of a unit? a. 9.4 units b. 18.8 units c. 28.3 units d. 56.5 units

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
