Answer:
Step-by-step explanation:
Fill in the table and you will see the formula above gives you the total. Substitute S=10 for you answer
How derive the formula?
You have to realize that you are give 3 to start with, so that's your starting constant. Filling in the table and subtracting 3 show help you see that the square of want is left after the subtraction is the square of the step.

Step-by-step explanation:
When we have a simple x = a equation, the line will be vertical since all y values of that function/equation are equal to a. In this case, that is 1.
Similar thing for a y = b equation. The line will be horizontal since all x values of that function/equation are equal to b. In this case, that is -5.
The point total possible for the given course is equal to 500.
What is a Percent?
- A ratio whose second term is 100 is known as a percent.
- Parts per hundred are used in percentages.
- The mathematical representation of percent is %.
- The percent formula is given as,
, where b is the base number, x is the number being compared to b, and p is the percent in decimal form.
In the question, it is given that you were 6 points shy of a B and the current total points you have is 394.
So, the total number of points you require for a B is calculated as,
So, the value of x is 400.
It is given that you need 80% of the course total for a B.
Here, we have to find the base number (b).
We have, x = 80% of b
Simplifying, we get
Therefore, 500 points were possible in the course.
