(please help I'm stuck) Amy designed a glass pyramid for a museum courtyard. Each side of the square base is 10 feet long. Each of the 4 triangular faces has a height of 10 feet. How much glass will be used to construct the base and the triangular faces? o 300 square feet
o 500 square feet
o 400 square feet
o 200 square feet​

positive

step-by-step explanation:

the quadrant is facing upwards

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.

the answer is 13/48
