Answer:
Suppose that you have a square of side length x, the area of this square will be:
A = x^2.
Now, by dynamics, we know that the position of an object that is falling down from a height H, can be written as:
H(t) = (-g/2)*t^2 + H.
We can see a pattern, x^2 is used in both.
Now, profit can be also modeled with quadratic equations, where our objective is to find the maximum of the quadratic (so we can have the maximum profit)
Then the parent function that is useful for gravity, calculating area and profit is the quadratic function:
f(x) = x^2

Step-by-step explanation:
Given : Giving a test to a group of students, the grades and gender are summarized below
A B C Total
Male 8 10 7 25
Female 6 13 14 33
Total 14 23 21 58
Total students = 58
Total number of students got A = 14
P(students got A)
Total number of students got A and not female = 8
P( students got A and not female ) =
Now , By conditional probability ,
P(NOT a female | got a "A" ) =
∴ The probability that the student was NOT a female that got a "A" is .
Answer:
Hey, where is the circle? I think you forgot to upload pic of circle.
Answer:
x=14
Step-by-step explanation:
6(-6+x)=76-2x
Distribute
-36 +6x = 76 -2x
Add 2x to each side
-36+6x+2x = 76-2x+2x
-36 +8x = 76
Add 36 to each side
-36+36 +8x = 76+36
8x = 112
Divide by 8
8x/8 = 112/8
x=14
