Answer:
It was an increase of 200%.
Step-by-step explanation:
In order to identfy the percent of the change we need to first find the absolute value, to do that we subtract the final value from the initial one. We have:
absolute difference = 36 - 12 = 24 inches
Since this value is positive it was an increase. Now we need to find the percentage at which it was increased, to do that we can use a rule of three in a way that the original value is 100% and the value we want to know is the percentage for the absolute increase. We do this as follows:
12 inches -> 100%
24 inches -> x %
12*x = 2400
x = 2400/12 = 200 %
It was an increase of 200%.
using the FOIL method the equation gets pretty long
Multiply each term by each term and combine like terms the given equation simplifies to:
f(x) = -2x^5 - 9x^4 - 8x^3 + 15x^2 +28x + 12
The degree is equal to the highest exponent, which is the 5 on -2x^5
The degree is 5
The y intercept is the value of y when x is 0
Replace all the x's with 0 and solve the equation:
f(x) = -2(0)^5- 9(0)^4 - 8(0)^3 + 15(0)^2 +28(0) + 12
= 0 -0 -0 + 0 +0 +12 = 12
The y intercept is (0,12)
Answer:
x=3.57142857143
Step-by-step explanation:
7x-5=30
30-5=25
7x=25
x=3.57142857143
I will answer these in the order they are given from the left to the right on the top.
1. 4p^3q^2
2. 8pq^5
3. 4p^2q^5
4. 8p^2q
5. 4p^2q (This one is not listed, but this is the greatest common factoring).
The way you do this is find the greatest common factor of the coefficients (front number) and
Look at variables that match and choose the smallest exponent as part of your gcf (this is how many times they match in both lists, making it a factor of both).
