Answer:

the dollar amount the club would have if they reached half of their goal T + 50

the dollar amount the club would have if every student at the school donated 50 cents to the cause 0,5T

the dollar amount the club could donate if they made $50 more than their goal 0.25n

the dollar amount the club would still need to raise to reach its goal after every student at the school donated 50 cents 0.5n

the dollar amount the club would have if half of the students at the school each gave 50 cents T - 0.5n

Step-by-step explanation:

the dollar amount the club would have if they reached half of their goal T + 50

the dollar amount the club would have if every student at the school donated 50 cents to the cause 0,5T

the dollar amount the club could donate if they made $50 more than their goal 0.25n

the dollar amount the club would still need to raise to reach its goal after every student at the school donated 50 cents 0.5n

the dollar amount the club would have if half of the students at the school each gave 50 cents T - 0.5n

Answer:

  a) 30 kangaroos in 2030

  b) decreasing 8% per year

  c) large t results in fractional kangaroos: P(100) ≈ 1/55 kangaroo

Step-by-step explanation:

We assume your equation is supposed to be ...

  P(t) = 76(0.92^t)

__

a) P(10) = 76(0.92^10) = 76(0.4344) = 30.01 ≈ 30

In the year 2030, the population of kangaroos in the province is modeled to be 30.

__

b) The population is decreasing. The base 0.92 of the exponent t is the cause. The population is changing by 0.92 -1 = -0.08 = -8% each year.

The population is decreasing by 8% each year.

__

c) The model loses its value once the population drops below 1/2 kangaroo. For large values of t, it predicts only fractional kangaroos, hence is not realistic.

  P(100) = 75(0.92^100) = 76(0.0002392)

  P(100) ≈ 0.0182, about 1/55th of a kangaroo
