Becky has been tracking the population of a town. The population was 5,340 last year and has been increasing by 1.75 times each

Scorpion4ik [409]

<span> the population grows at rate of 1.75
multiply it by this rate every year
As in year 3 it would be 5340(1.75)(1.75)(1.75) the function is 5340(1.75)^x
</span>f(x) = 5340(1.75)^x where 1.75 is the rate of growth
so D is right answer

A right come has a volume of 24pie cubic meters and a radius of 3 meters find the height of the cone

JulijaS [17]

Hello!

The equation for find the h when given volume and radius is

$h = 3 \frac{V}{ \pi r^{2} }$

h is height
v is volume
r is radius

Put in the values you know

$3 \frac{24 \pi }{ \pi 3^{2} }$

Since there is pi on the top and bottom we can get rid of it

multiply the 3 by the top number

$\frac{72}{9}$

the answer is 8m

Hope this helps!
