Look at this rectangular prism: |2yd
6yd
3 yd
If all three dimensions are doubled, then which of the following
statements about its surface area will be true?
The ratio of the new surface area to the old surface
area will be 1:4.
The ratio of the new surface area to the old surface
area will be 2:1.
The ratio of the new surface area to the old surface
area will be 16:1
The ratio of the new surface area to the old surface
area will be 4:1.

ab will be equal to

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.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
