Aboat drops an anchor 17.5 feet to the bottom of a lake. if the anchor falls at a rate of .07 feet each second how long will it take the anchor to reach the bottom of the lake?

25 Seconds.

Step-by-step explanation:

You need to know how many seconds it takes to read the bottom of the lake.

If, each second, the anchor is falling 0.7 feet, then you need to know how many times it falls 0.7 feet.

This is done by dividing 17.5 by 0.7, which is 25 seconds.

24

step-by-step explanation:

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.
