Andre has 45 sheets of paper and needs to buy more. a store has 5 reams of paper, and each
ream contains 500 sheets of paper. the number of sheets of paper andre has after
purchasing x reams is represented by a function.
f(3) = 500.+ 45
what is the practical domain of the function?
{545, 1045, 1545, 2045, 2545}
o all real numbers from 1 to 5, inclusive
o all real numbers
o
all integers from 1 to 5, inclusive

i pretty sure it is

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.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

i think the answer is c sorry if it's wrong
