| 2) In archery, the arrow appears to travel in a straight line
when it is released. However, the arrow will actually travel
upward slightly before curving back down toward the earth.
For a particular archer, the arrow starts at 5.4 feet above
the ground. After 0.3 seconds, the arrow is 5.5 feet above
the ground. The arrow hits the target after a total of 2
seconds at a height of 5 feet above the ground. Create a
y = ar? +bx+c that would
quadratic equation in the form
model this data.

a

step-by-step explanation:

the answer is a

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.
