Example: A path from a dry lake bed starts at an elevation of 212 1··2ft relative to sea level. The path ends at an elevation of 60 1··3ft above sea level. What number represents the change in elevation from the start to the end of the path? Question: The lowest point of the dry lake bed in the Example has an elevation of 218 3··4ft. What number represents the change in elevation from the start of the path to the lowest point in the dry lake bed? Show your work.

answer: ouch. thats difficult

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.

i'm sorry i don't know

step-by-step explanation:

you first to choose the points and then move from then as the slope you have
