An airplane travels 1200 miles from Annapolis to Dallas in 4.8 hours, going against the wind. The return trip is with the wind, and takes only 4 hours. Find the rate of the airplane with no wind. Find the rate of the wind. The airplane flies at 275 mi/h with no wind. The rate of the wind is 25 mi/h.
The airplane flies at 250 mi/h with no wind. The rate of the wind is 50 mi/h.
The airplane flies at 275 mi/h with no wind. The rate of the wind is 50 mi/h.
The airplane flies at 250 mi/h with no wind. The rate of the wind is 25 mi/h.

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.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

the answer to that one is b
