Answer:

\boxed{D. \: (f-g)(x) = {x}^{2} + 4x + 3}

Given:

f(x) =2 {x}^{2}  - 5 \\ g(x) =  {x}^{2}  - 4x - 8

To find:

(f - g)(x) = f(x) - g(x)

Step-by-step explanation:

\implies(f - g)x = f(x) - g(x) \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    = (2 {x}^{2}  - 5) - ( {x}^{2}  - 4x - 8) \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    = (2 {x}^{2}  - 5)  + (-  {x}^{2}  + 4x + 8) \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    = 2 {x}^{2}  - 5 -  {x}^{2}  + 4x + 8 \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    = 2 {x}^{2}  -  {x}^{2}  + 4x - 5 + 8 \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    =  {x}^{2}  + 4x + 8 - 5 \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    =  {x}^{2}  + 4x + 3

What is the volume of the composite figure? Use 3.14 for π and round the answer to the nearest tenth of a cubic unit.
SSSSS [86.1K]
To calculate for the total volume of the figure above, we add the separate volume of the cylinder and the cone. The volume of a cone is calculated from the product of the area of the circle times its height. The volume of the cone is calculated by 1/3 the product of the area of the base times the height. 

V = Vcylinder + Vcone
V = πr²h + πr²h/3
V = π(6)²11 + π(6)²9/3
V = 1583.4 in^3 -------> closest to third option

Find the first four terms of the infinite sequence defined explicitly by the following rule.
Nataly_w [17]
The only thing that you should do is to put 1, 2, 3, and 4 instead of the n and then you will get the first four terms! 

f(1) = 4(1) - 2 = 2 
f(2) = 4(2) - 2 = 6
f(3) = 4(3) - 2 = 10 
f(4) = 4(4) - 2 =  14 

Have a great day!

patriot [66]

The inequality to find the maximum number of t-shirts is:

22+8x\leq 60

Step-by-step explanation:

Debbie has at most $60 to spend

Then it will be <=60

Now she has to spend 22 dollars on jeans so 22 will be add to the initial amount for sure.

And

Let x be the number of t-shirts

Then the cost of x t-shirts will be 8x

Putting this in to inequality will be:

22+8x\leq 60

The inequality to find the maximum number of t-shirts is:

22+8x\leq 60
