Answer:
b = 2
Step-by-step explanation:
Given
2b + 5 = 9 ( subtract 5 from both sides )
2b = 4 ( divide both sides by 2 )
b = 2
Answer: (4, -1)
Step-by-step explanation: You have to rewrite in vertex form and use the form to find the vertex
Answer: First Option
Step-by-step explanation:
The formula to calculate the volume of a cylinder is:

Where d is the diameter of the cylinder and h is the height.
Notice that the term d is squared. This means that to increase the volume of a cylinder it is more efficient to increase its diameter as well. Therefore, look for the cylinder with the largest diameter among the options.
The first cylinder is 90 ft in diameter and 40 ft in height and its volume is


You can verify that it is the tank that has the highest volume
Answer:
Therefore,

Step-by-step explanation:
Given:
0° < θ < 360°
tan θ = 3.5134
To Find:
θ in degrees = ?
Solution:
0° < θ < 360° .............Given
Means ' θ ' is between 0° and 360°
.............Given
Therefore,

Also,

So ' θ ' will have Two values for tan θ =3.5134

Therefore,

Answer:
I think it's 5(9)+20
Step-by-step explanation:
5(9+4) can be expanded to get 5(9)+5(4). And 5(4)=20
