Cell X has a surface area of 60\, \mu\text{m}^260μm 2 60, mu, start text, m, end text, squared and a volume of 15\, \mu\text{m}^315μm 3 15, mu, start text, m, end text, cubed. Cell Y has a surface area of 36\, \mu\text{m}^236μm 2 36, mu, start text, m, end text, squared and a volume of 12\, \mu\text{m}^312μm 3 12, mu, start text, m, end text, cubed.

i hope this is what you were looking for.

see attached graph

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.
