You have a triangular-shaped pennant hanging on your wall. The base of the pennant. Is 18 inches. The height is 1 foot. How much wall space does your pennant take up?

9

Step-by-step explanation:

18 times 1

then divided by 2

is 9

108 inches

Step-by-step explanation:

A=hb/2

A=(12·18)/2

A=108

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.

it would rotate about 180 degrees.
