Answer:
1. Factorization method
2. Formula method
3. Completing the square method
4. Graphical method
Step-by-step explanation:
There are four methods of solving quadratic equation:
1. Factorization method
2. Formula method
3. Completing the square method
4. Graphical method
1. Factorization method: Use factorization method when the quadratic equation can easily be factorize.
Example: x^2 - 4x - 12 = 0
(x-2)(x+6)
2. Formula method: This can be used when factoring the quadratic equation looks difficult or you are given instruction to use formula method
3. Completing the square method: Use completing the square method when you are instructed to do so.
4. Graphical method: This method is used when instructed to find x intercept.

Answer:
Half of year 2043
Step-by-step explanation:
The function is: f(x) = 3.5√x + 38
where f(x) represents the percentage of U.S. women in the labor force x years after 1960.
Replacing f(x) = 70 and isolating x, we get:
70 = 3.5√x + 38
3.5√x = 70 - 38
√x = 32/3.5
x = 9.14²
x = 83.5
This means, in year 1960 + 83.5 = 2043.5, that is, at half of year 2043
Answer:
Rise over Run.
Step-by-step explanation:
If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.
I'm sorry that might not make much sense I'm bad at explaining but let me know if that helps at all!!
