A rectangle with a perimeter of 80 was cut in half through its width w to produce a smaller rectangle with a perimeter of 80 - W. Applying the same cut
(parallel to the initial cut) to the smaller rectangle produced a new rectangle
with a perimeter of 80 - 1.5w. Applying one more like cut to the most recent
rectangle resulted in a rectangle with a perimeter of 38.

step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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.
