First, we need to find out how much the price increased by.
$4.50 - $3.75 = $0.75
Now we have to figure out what percent $0.75 is of $3.75. To do this, we divide $0.75 by $3.75.
The answer is 0.2. Now, we convert this into a percent by moving the decimal to the right by to spaces: 0.2 = 20%
The percent of increase is 20%.
Answer:
20 elements.
Step-by-step explanation:
Lets say
n(U) = 114
n(A) = 57
n(B) = 79
n(A n B)= 42
Now,
n(A U B) = n(A) + n(B) - n(A n B)
= 57 + 79 - 42
= 94
Now,
n(A U B) compliment = n(U) - n(A U B)
= 114 - 94
= 20
Distribute sum groups
x(x^2 + 4x - 2) - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - (5x^2 + 20x - 10)
Simplify brackets
x^3 + 4x^2 - 2x - 5x^2 - 20x + 10
Collect like terms
x^3 + (4x^2 - 5x^2) + (-2x - 20x) + 10
Simplify
<u>x^3 - x^2 - 22x + 10</u>
I'm not just going to give you that answer, i'm going to teach you how to do it for yourself. this is a function. what you do first is look at what the question is asking you, it's asking you to solve the function, when the value of x are as follows: -2, 1, 2. start with the easiest number, 1, and plug it in for x in each equation.
5• (1)^2 + 0
10• (1)^2 + 0
then set each equation equal to zero
5 • (1)^2 + 0 = 0
10 • (1)^2 + 0 = 0
now solve each equation. make sure the value value you get for the first equation is a negative number, because the question demands that by giving you "x<1"
complete the same steps for each other value to get the answers. hope this helps.
