3. A rocket is launched vertically from the ground with an initial velocity of 64 . (a) Write a quadratic function that shows the height, in feet, of the rocket t seconds after it was launched. (b) Determine the rocket’s maximum height, the amount of time it took to reach its maximum height, and the amount of time it was in the air. Show work for all steps. (c) Graph on the coordinate plane using important information from part b.

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.

just get this app called photo math it should be able to do those

step-by-step explanation:

sorry i just needed points for a quiz plz for give me
