Answer:
a1 = 0.5; common ratio = 5
Step-by-step explanation:
Let the common ratio = r
a2 = 2.5
a3 = 2.5r
a4 = 2.5r * r = 2.5r^2
We are told a4 = 62.5, so
2.5r^2 = 62.5
Divide both sides by 2.5
r^2 = 25
r = 5
a2 = a1 * r
a1 = a2/r = 2.5/5 = 0.5
Answer: a1 = 0.5; common ratio = 5

Answer:
X=2
Step-by-step explanation:
2(12x-8) + 1/3 x 9 =35
24x -16 + 3 = 35
24x = 48
X = 2
C. The rate of change of the radius is a cubic relationship
Answer:


Step-by-step explanation:
The functions, missing from the question are:


Required
Determine the domain
To get the domain, means we want to get the possible values of x.
(a)

Equate 3 - x to 0

Solve for x


From the calculated value of x above;
When x exceeds 3; f(x) = undefined
So: the domain is:

(b)

Equate 3x to 0

Solve for x

From the calculated value of x above;
When x falls below 0; f(x) = undefined
So: the domain is:
