The bird population on an island is declining at a rate of 2.2% per year. the population was 3500 in the year 2016. what will be the population in the year 2022?

3,063

Step-by-step explanation:

To find the population in a future year, use the formula:

where A is the amount, p is the starting population, r is 2.2% or 0.022, and t is the number of years after 2016.

Since the population is decreasing it is subtraction. Here we are finding A, P =3500, r=0.022, and t=6.

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

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
