6. The mass of Mars is 6.42 x 10^23 kilograms. The mass of Mercury is 3.3 x 10^23 kilograms. a. What is the combined mass of Mars and Mercury expressed in scientific notation? b. What is the difference in the mass of the two planets expressed in scientific notation? PLEASE ANSWER WITH COMPLETE STEPS;) THANK YOU. (I giving 20 pts)

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.
