You are printing posters for a concert and need them to be 35" tall. the small copy you
have is 8" wide by 10" inches tall.

part a. what scale factor should you use when enlarging the image to make sure proper proportions are maintained?

part b: how wide will the enlarged poster be?

part c: how do the areas of the posters relate to one another? what are two ways you can justify your answer?

could you reply to this with the question so i can ?

answer: the first graph

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
