Answer:
In Nelson Mandela's family he was the first to receive a formal education. At that time, very few black kids attained high school education in South Africa.
Answer: The first interval:0 ≤ x ≤ 20
Procedure
You have to solve this inequality
-2x^2 +40x +600 ≥ 600
-2x^2 +40x ≥ 0
-x^2+20x ≥ 0
x^2 - 20 x ≤ 0
x(x-20) ≤ 0
That is only possible if the two factors have different signs.
Let's examine the possibilities
x ≥ 0 and x -20 ≤ 0⇔x≤20, that is 0≤x≤20
The other possibility is
x ≤ 0 and x - 20 ≥ 0 ⇔x≥20. This conditions is not possible.
So the solution is 0≤x≤20
Answer:
The separated values of x and y from the given equation is
Step-by-step explanation:
Given equation is
Now to find the separated values of x and y with the given equation.
Now find the value of x and so we have to separate the value x from the given equation
Therfore
Now find the value of y and so we have to separate the value y from the given equation
Therefore
The separated values of x and y from the given equation is
A square pyramid is called like so because its base is a square.
notice this one, its base is a 0.4x0.4 square, and the triangular faces have a base of 0.4 and an altitude or height of 5.
so we can simply get the area of the base and all four triangular faces and sum them up, and that's the surface area of the pyramid.
