You're in charge of the firewords display for the neighborhood party this year. Depending on the shell size the fireworks will explode at various heights. A 10-inch shell that is fired can reach a height of 1200 feet. If it is launched at an angle of 65°, how far away (x) would someone have to be sitting to be directly under the explosion? Round your answer to the nearest foot and show all work on the whiteboard.

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.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

1st part is 64,000,000

2nd part 500,000
