sound intensity, i, from a spherical source is a function of the distance, r, from the source of the sound. it is represented by the function

i= p/4pir^2

where p is the power of the sound. explain the behavior of the graph of i and what it means in context.

The vertical asymptote is r = 0.

The intensity is undefined at the source.

The horizontal asymptote is I = 0.

As the distance from the source increases, the intensity goes to zero.

The intensity decreases as the distance increases.

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.

yes the data was not prsented
