Answer:

13

Step-by-step explanation:

(f∘g)(4) is another way of writing f(g(4)).

First, find g(4).

g(x) = 2x − 3

g(4) = 2(4) − 3

g(4) = 5

Now substitute into f(x).

f(x) = 4x − 7

f(g(4)) = 4g(4) − 7

f(g(4)) = 4(5) − 7

f(g(4)) = 13

(f\circ g)(x)=4(2x-3)-7=8x-12-7=8x-19\\\\(f\circ g)(4)=8\cdot4-19=13

The price of a bottle of shampoo was marked up 15%, then marked down 4%. If the original price was $4.50, what is the new price?
balandron [24]

Answer:

Cost of shampoo = $4.50

% Mark up of Shampoo = 15%

15% Mark up of Shampoo = 15/100 x $4.50 = $0.67

Price of Shampoo 15% Mark up = $4.50 + $0.67 = $5.17

% Mark down of Shampoo = 4%

4% Mark down of shampoo = 4/100 x $5.17 = $0.21

Price of Shampoo 4% Mark down = $5.17 - $0.21 = $4.96

100 POINTS! I REPEAT 100 POINTS! PLEASE HELP!
AURORKA [14]
First you need to find the area of the lawn. To find the area of a square, you multiply two sides together. You have two sides given, which is super helpful.

I put in my calculator, (40+4/5)x(50+7/8) and this gave me the answer of 2075.7.
You need to then divide that number by 500, and divide it by 300, and then round up, cause if you round down you’re not gonna have enough seed.

2075.7/500 = 4.1514, but then this needs to be rounded up or he’ll be 0.1514 short. So he needs 5 bags for the highest setting.

2075.7/300 = 6.919, so for the lowest setting, he needs 7 bags of seed.

This should be correct.

Hope this helps :)
