2. A researcher is observing dophin behavior from the top of an 171.5 ft lighthouse. Luckily, she was able to drive up the 654 ft cliff to reach the entrance to the lighthouse.
When she first begins watching the dolphins the angle of depression to the dolphins was
15.5'. As the dolphins started to swim towards her, she notices the angle of depression is
now 35.4'. Find the distance the dolphins traveled between the two points of observation

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.

the correct answers i think are b. and d.

give me brainliest if it is correct!
