For this case we must solve the following expression:
÷ 
According to the PEMDAS algebraic order method, we have the following order:
P: Parenthesis
E: Exponents
MD: Multiplication and division
AS: Addition and subtraction
So, we have:
Answer:
Answer:
12.56
Step-by-step explanation:
area of a circle is A=πr^2
radius is 2
a= 3.14 (2)^2
=3.14 x 4
=12.56
Answer:
24
Step-by-step explanation:
Answer:
Find the minimum and maximum values of the objective function subject to the given constrants. Objective function: C= 2x + 3y
Constraints:
x>0
y>0
Comment: These two conditions tell you the answers are in the 1st Quadrant.
-----------------------------
x +y < 9
Graph the boundary line: y = -x+9
Solutions points are below the boundary line and in the 1st Quadrant.
The rule is that y equals 4 times x.
Whatever value of x you have, multiply it by 4 to find the corresponding y value.
If x = 3, y = 4 * 3 = 12
If x = 4, y = 4 * 4 = 16
If x = 5, y = 4 * 5 = 20
The table looks like this:
x y
3 12
4 16
5 20
