Answer:
21
Step-by-step explanation:
f(x) = (x − 8)(x + 8)
f(x) = x(x − 8)^2
f(x) = x(x^2 − 8)
Answer:
Constant of variation is,
Step-by-step explanation:
Joint Variation states that it is jointly proportional to a set of variables i.e, it means that z is directly proportional to each variable taken one at a time.
Given the statement: The quantity n varies jointly with the product of z and the square of the sum of x and y.
"The square of sum of x and y" means
"Product of z and the square of the sum of x and z" means
then; by definition we have;
our equation will be of the form of:
......[1] ; where k is constant of Variation.
Given: n =18 , x =2 , y= 1 and z = 3
Solve for k;
Substitute these given values in [1] we have;
Simplify:
Divide both sides by 27 we get;
therefore, the constant of variation is,
The other endpoint will be equal to (-7, -2).
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the midpoint of cd is e ( -1,0 ) one endpoint is c( 5,2 ). The midpoint will be calculated as:-
Midpoint = (x₁+x₂ / 2 , y₁+y₂ / 2)
5 + x₂ / 2 = -1
5 + x₂ = -2
x2 = -7
2 + y₂ / 2 = 0
2 + y₂ = 0
y₂ = -2
Therefore, the other endpoint will be equal to (-7, -2).
