A seagull is tired and decides to fly down and sit in a wave pool. Due to the waves, the seagull is going up and down. After 10 seconds, the seagull is at its maximum height, 9 feet above the bottom of the pool. Every 20 seconds, the seagull returns to that high point. At its lowest, the seagull is 3 feet above the bottom of the pool. Create a sketch. Must draw on your own paper. Remember to label your axes.

c

step-by-step explanation:

1/800 is the right answer

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.
