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
Blaine's Company: 103 x 6 = 618
William's Company: 1.2 x 105 = 126
Since William's Company made 126 x Blaine's company's
126 x 618 = 77868.00

Answer:
3/(x +1) -4/(x +1)^2
Step-by-step explanation:
The partial fraction expansion will be of the form ...
A/(x+1)^2 +B/(x+1)
We can find the values of A and B by writing the sum of these terms:
= (A +B(x +1))/(x +1)^2
Then we require ...
B = 3
A +B = -1 ⇒ A = -4
So, the desired expansion is ...
3/(x +1) -4/(x +1)^2

The angle we can see, in GHI, is equal to 121°. JKL has an identical angle, meaning JKL is an enlargement (probably the wrong term, I apologise) of GHI. This means we can use the length of it's sides to find KL.
GH and GI are both multiplied by two (GH = 4 becomes JK = 8, GI = 5 becomes JL = 10) meaning you must multiply HI by 2 to find KL.
2*7 = 14
KL = 14
