<span>Gymnast Clothing manufactures expensive hockey jerseys for sale to college bookstores in runs of up to 300. Its cost (in dollars) for a run of x hockey jerseys is
C(x) = 3000 + 10x + 0.2x2 (0 ? x ? 300)
Gymnast Clothing sells the jerseys at $105 each. Find the revenue function.</span>

Answer:
nx^(n-1).
Step-by-step explanation:
d/dx (x^n)
We multiply by n than subtract 1 from the exponent (n):
= n x^(n-1)
Numerical examples:
d(x^3) dx = 3 * x^(3-1)
= 3x^2.
d(2x^5)/dx = 5*2 x^(5-1)
= 10x^4.
Answer:
26 and 27
Step-by-step explanation:
The first integer = x
Therefore the second integer = x + 1
according to the statement we obtain the equation
(x) + (x + 1) <55
x + x + 1 <55
2 * x + 1 <55
We subtract 1 from both sides, we get:
2x <54
divide both sides by 2 we get:
x <27
Therefore the first integer is 26, since it has to be better than 27.
the second integer = x + 1
= 26 + 1
= 27
If we add 26 + 27 = 53, which is less than 55 and the condition is met
Answer:
Step-by-step explanation:
<u>To increase a value by 10% let's take 2 steps.</u>
1. Find the 10% of 120.
10%= 0.1
120 * 0.1= 12.
2. Add 12 to 120.
120 + 12= 132.
3. Present your result.
$132.
<u>Secondary method.</u>
This is a more advanded way of finding the result in one step.
For example, if you want to increase a number by 10% you multiply it by 1.<u>1</u>. Hence, 120 with a 10% increase is:
120 * 1.1= <u>132</u>.
Another example. Let's increase 120 by 50%. For this, we multiply by 1.<u>5</u>.
120 * 1.5= <u>180</u>.
Finally, let's make an example of decreasing. Decreasing works a little different. For example, you would think that getting a 70% decrease of a value is just multiplying the value by 0.7, but that's not true. To get a decrease of 70% in 90, for example, you must multiply by 1-70%:
90 * (1- 70%)=
90 * (1- 0.7)=
90 * (0.3)=
<u>27.</u>
<u>-------------------------------------------------------------------------------------------------------</u>
How to verify?
Let's take 10% of the original number, and substract from 132:
