Question

Ughh , anyone know how to do this or what the answer is

Answer 1

Answer:

1730

Step-by-step explanation:

The exponential function is of the form

y = a × $b^{n}$

where y is the insect population and n the number of weeks

a and b have to be found by using values from the table.

Using (0, 20), then

20 = a × $b^{0}$ ⇒ a = 20

Using (1, 30), then

30 = 20 × $b^{1}$ ⇒ b = $\frac{30}{20}$ = 1.5

Hence

y = 20 × $1.5^{n}$ ← exponential function

When n = 11

y = 20 × $1.5^{11}$ ≈ 1730 ( nearest whole number )
