A football player kicked the ball from on top of a platform. The flight of a kicked football follows the quadratic function f(x) = - 0.02x ^ 2 + 2.2x + 12 f(x) is the vertical distance in feet and the horizontal distance the ball travels. which is the highest point the football will reach, in feet? Round to one decimal place.

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.

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
