Apicture 10 1/4 feet long is to be centered on a wall that is 14 1/2 feet long. how much more space is there from the edge of the wall to the picture?

2 1/8 ft

Step-by-step explanation:

The distance from the centerline of the picture to its edge is half the width of the picture:

... (10 1/4)/2 = 5 1/8 . . . . feet

The distance from the centerline of the wall to its edge is half its width:

... (14 1/2)/2 = 7 1/4 . . . . feet

When the centerlline of the picture is aligned on the centerline of the wall, the distance from the edge of the picture to the edge of the wall is ...

... (7 1/4 ft) - (5 1/8 ft) = 2 1/8 ft

In inches, this is (2 1/8 ft)×(12 in/ft) = 24 12/8 in = 25 1/2 in.

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.
