The revenue from selling x hats is r(x)=18x The cost of buying x hats is c(x)=8x+30. The profit from selling x hats is p(x)=r(x) -c(x)
Write a function for p(x), the profit from selling x hats
1 answer:
Answer:
The correct answer is c) p(x)=10x-30
Step-by-step explanation:
The answer is given in the question, you just have to replace r(x) and c(x) in the profit formula.
p(x)=r(x)-c(x)
The revenue is: r(x)=18x The cost is c(x)=8x+30
p(x)=18x-(8x+30)
Solving=
p(x)=10x-30
<em>Be careful with the signs </em>
So the correct answer would be option :
c) p(x)=10x-30

2 * 4 = 8
8 < 11 is true
2 * 5 = 10
10 < 11 is true
2 * 5.3 = 10.6
10.6 < 11 is true
2 * 5.7 = 11.4
11.4 < 11 is NOT true.
x = 5.7 is not a solution.
Answer:
64*(1/4)^x
Step-by-step explanation:
64 is the starting number because it is given, and x represents how many rounds there are. 1/4 represents how much of the teams remain after each round.
Answer:
Step-by-step explanation:
Let the other leg = x
x^2 + 4^2 = (3x)^2
x^2 + 4^2 = 9x^2
4^2 = 9x^2 - x^2
16= 8x^2
16/8 = x^2
x^2 = 2
x = sqrt(2)
The lengths of the sides
x = sqrt(2)
other side =4
hypotenuse = 3*sqrt(2)
x = 1.4
other side= 4
hypotenuse = 3*1.4142
hypotenuse = 4.2
