Diameter = 8 cm

radius = diameter/2 = 4 cm

A = pi * r^2

A = pi * (4 cm)^2

A = 16pi cm^2

Derek found a function that approximately models the population of iguanas in a reptile garden, where x represents the number of

serious [3.7K]

Answer:

$i(x)=12 \times (1+\frac{0.9}{12})^{12x}$ and growth rate factor is 0.075

Step-by-step explanation:

The function that models the population of iguanas in a reptile garden is given by $i(x)=12 \times (1.9)^{x}$ , where x is the number of years.

Since, $i(x)=12 \times (1.9)^{x}$

i.e. $i(x)=12 \times (1+0.9)^{x}$ .

Therefore, the monthly growth rate function becomes,

i.e. $i(x)=12 \times (1+\frac{0.9}{12})^{x \times 12}$ .

i.e. $i(x)=12 \times (1+\frac{0.9}{12})^{12x}$ .

Hence, the monthly growth rate is i.e. $i(x)=12 \times (1+\frac{0.9}{12})^{12x}$ .

Also, the growth factor is given by $\frac{0.9}{12}$ = 0.075.

Thus, the growth factor to nearest thousandth place is 0.075.

kolbaska11 [484]

Answer: 0.5

Step-by-step explanation:

Android calculator accepts the above question via copy and paste, and gives 0.5

The point of this question is to try to discover whether or not you know what the expression means.

Rewriting it as (8(15-4)/(4×4)) - 5 would show that you know the meaning. You can check that by feeding it into the calculator as well.
