Answer:

a_{5} = 96.

Step-by-step explanation:

Given  : a_{n} = n^{3} +n^{2} -9n -9.

To find : What is the fifth term of the sequence .

Solution : We have given a_{n} = n^{3} +n^{2} -9n -9.

For n = 5

a_{5} = 5^{3} +5^{2} -9(5) -9.

Open the cubes and squares

a_{5} = 125 + 25  - 45  -9.

Add the terms

a_{5} = 96..

Therefore,  a_{5} = 96.

What is the sum of the first 5 terms of a geometric series with a sub 1 = 10 and r = 1/5?
Mice21 [21]

Answer:

a 1 = 10

a 2 = 10 * 1/5 = 2

a 3 = 2 * 1/5 = 2/5

a 4 = 2/5 * 1/5 = 2/25

a 5 = 2/25 * 1/5 = 2/125

S 5 = a 1 + a 2 + a 3 +a 4 + a 5= 10 + 2 + 2/5 + 2/25 + 2/125 =

= 1250/125 + 250/125 + 50/125 + 10/125 + 2/125 = <u> 1562 / 125</u>

In the equation f(x)= 5(x+3)^2-10 what effect does the 5 do when compared to the parent function?
Lostsunrise [7]

Answer:

The correct answer is A. Vertical compress by a factor of 5

Step-by-step explanation:

When graphed without the 5, the curve is very wide, but when the 5 is added, the curve compresses and narrows itself, therefore a vertical compress occurs by the factor of 5.
