Step-by-step explanation:
Answer is a.
Answer: a=4 or a= −3, so you can use anyone of the answers.
Step-by-step explanation:
Solve Absolute Value.
|2a−1|=7
We know either 2a−1= 7or 2a−1 = −7
2a−1=7(Possibility 1)
2a−1+1=7+1(Add 1 to both sides)
2a=8
(Divide both sides by 2)
a=4
OR,
2a−1=−7 (Possibility 2)
2a−1+1= −7+1 (Add 1 to both sides)
2a= −6
(Divide both sides by 2)
a= −3
Therefor the answers are a=4 or a= −3
* Hopefully this helps:) Mark me the brainliest:)!!
So the radius is 5 cm
and we are given the volume at 225 cm³
now breakdown the volume formula for a cone which is V equals 1/3 Bh
b= pi r squared
now substitute everything in
225 equals 1/3 pi(5)^2 Times h
since we don’t know H that is what we’re solving for
225= 1/3 pi(25) times h
multiple 3/1 on both sides to cancel the 1/3
675= 25(3.14) times h
675= 78.5 (h)
h= 675/78.5
h=8.60 cm
Answer: B. objective is expressed in terms of the decision variables
Step-by-step explanation:
Linear programming refers to an optimization technique that is used for a linear constraints system and the objective function.
The objective function simply means the quantity that an individual wants to optimize. It should be noted that the aim of linear programming is to get the values of the variables which will minimize or maximize the objective function. In problem formulation, objective is expressed in terms of the decision variables.
Therefore, the correct option is B
Answer:
The negative of a negative is a positive. You can rewrite the equation as -3+1. So, the answer is -2.
