9. Given f(x) = 7x2 and g(x) = x +1,
find f(g(x)). SHOW ALL WORK.

Answers

Answer 1
Answer:

I hope this helps you

f(g(x)) =f(x+1)=7(x+1)^2

f(x+1)=7.(x^2+2x+1)

f(x+1)=7x^2+14x+7
Answer 2
Answer:

f(g(x)) simply means g(x) is substituted for x in f(x)=7x^2

Since g(x)=x+1, then f(x)=7(x+1)^2

f(x)=7(x^2+2x+1)

f(x)=7x^2+14x+7

So f(g(x))=7x^2+14x+7

Lorraine works at a gift shop. She buys 500 accessories at $1.25 each. She resells them all to make a profit of $375.00.What percent does she mark up the price of each accessory?

Answers

Profit percent made by Lorraine is 60%

Explanation:

Given:

Number of accessories = 500

Cost of each gift = $1.25

Profit = $375

Profit% = ?

Total price of the gift = 500 X $1.25

Cost price = $625

Profit = SP - CP

$375 = SP - $625

SP = $1000

Profit % = ((SP-CP)/(CP) ) X 100

P = ((1000 - 625)/(625)) X 100 \n\nP = 60%

Therefore, profit percent made by Lorraine is 60%

Find the area of the shape shown below

Answers

Answer:

12

Step-by-step explanation:

My suggestion for this problem is to break the shapes up like outlined on the problem so you have a square and two triangles.

First Triangle: 2

The legs of the triangle are 2 so you plug it in for the formula for a triangle's area: A=1/2bh

A=1/2(2)(2)= 2

Square: 4

multiple length times width so you get 2*2 = 4

Last Triangle: 6

A=1/2(2)(6)=6

At the end you add up your areas and you get 2+4+6=12

70 is the 100% so 70 is the denominator for the second problem and your trying to find out what the n is.

n is your problem 156% of 70 = n
