Answer:
The answer to your question is: V = 5x² + 40x + 80
Step-by-step explanation:
Formula = V = r²h
r = x + 4
h = 5
Substitution
V = (x + 4 )² 5
V = (x² + 8x + 16)5 expand
V= 5x² + 40x + 80 simplify
Answer:
The answer is C. 16
Step-by-step explanation:
Notepads of the same color = 4
As we have two sizes then total for the same color = 
Notepads of the different colors as we have to choose 3 different colors out of 4 = 4C3 = 4
For two sizes the total for the different color =
We can group these like - Same size same color package:
There are eight combinations
Size 1:
BBB
GGG
YYY
PPP
Size 2:
BBB
GGG
YYY
PPP
Next groups form like : Same size different color
Size 1:
BGY
BYP
GYP
BGP
Size 2:
BGY
BYP
GYP
BGP
So, we get total =
Answer:
y = 100 - 2.5 x is the equation that represents her total profit from
the project
Step-by-step explanation:
The given is:
1. An electrician earns 100 dollars for a project installing light fixtures
2. She must pay for the light fixtures herself and they cost 2 dollars
and 50 cents each
3. x represent the number of light fixtures and y represent her
total profit
Her profit is the amount of money she has left over after paying for
the light fixtures
∵ The cost of each light fixtures is 2 dollars and 50 cents
- Let us change the cents to dollar
∵ $1 = 100 cents
∴ 50 cents = dollar
∴ 2 dollars and 50 cents = $2.5
∵ Her profit = The money she earns - The money she pays
∴ The cost of each light fixtures = $2.5
∵ She installs x light fixtures
∴ She pays 2.5 x dollar
∵ She earns $ 100 for installing x light fixtures
∵ Her profit is $y
∴ y = 100 - 2.5 x
y = 100 - 2.5 x is the equation that represents her total profit from
the project

I hope this helps!
The answer is B
See if we shift pt C by one box upwards and 3 box rightward we reach pt C' , each box represent 2 units so the translation is x--> x+6
And y--> y+2
Answer --> b
