X^2+y^2 = 16
can be written as
(x-0)^2+(y-0)^2 = 4^2

We see that the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2

where
(h,k) = (0,0) is the center
r = 4 is the radius

The polar form of the equation is simply r = 4. Why is this? Because the radius is fixed to be 4 no matter what happens with theta. As theta goes from 0 to 360, the points generated all form a circle centered at (0,0) with radius 4.

Answer: r = 4

If a city that currently has a population of 1000 triples in size every 8 years, what will the population be in 24 years? Is the

Brilliant_brown [7]

For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
Substituting values we have:
y = 1000 * (3) ^ ((1/8) * t)
For 24 years we have:
y = 1000 * (3) ^ ((1/8) * 24)
y = 27000
Answer:
D) 27,000; exponential

Answer:

Step-by-step explanation:

cube means 3D square.. right?

so for volume we want the height x width x length.. make sense?

since each edge is 9'

the volume is $9^{3}$ = 729 $ft^{3}$
