The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120
First, write an equation
x+7.9= 8.3
Now solve for x.
x=0.4
First the question asks you how many problems Cesar did per day in a 5 day school week. We know that he did 100 problems in that 5 day week, so you should divide 100 by 5 to get 20. Now we know that Cesar does 20 problems per day. Now the question want you to find how many problems he would do if this rate keeps up in three 5 day weeks. We know that he does 100 problems in a five day week, so multiply 100 by 3 to get 300. So Cesar does 300 percent problems in three weeks and 20 problems in one day.
Answer:
Area = 110 cm²
Step-by-step explanation:
You can find the area of a regular pentagon by finding the area of one of the triangles created by its central angle and multiplying it by 5.
1. Use the formula for the area of a triangle to find the area of the triangle formed by its central angle.

2. Multiply this area by 5 to get the area of the entire pentagon.
A = 22(5)
A = 110
