Step-by-step explanation:
15x3=45 or it could be 3-15
Replace 7 for the variable, t. N= 2000(2(7))= 28000
Answer:
h = 5.705m
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of the cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
V = 363 cubic meters
d = 9m
h = ?m
d = 2r
d - diameter
r - radius
r = d/2
r = 9/2
π- 3.142
Insert the values into the formula of volume of cylinder
V = πr^2h
363 = 3.142 * (9/2)^2 * h
363 = 3.142 * 81/4 * h
363 = 63.6255h
Divide both sides by 63.6255 to get the value of h
363/63.6255 = 63.6255h/63.6255
5.705 = h
h = 5.705m
Answer:
x = -7, x = 7
Step-by-step explanation:
Firstly, you are going to set the equation to 0, and then factor it.
Set equation to 0 -----> f(x)= x^2 - 49 will become x^2 - 49 = 0
Now, you're going to factor the equation.
You'll get (x-7) (x+7) upon factoring.
Thirdly, you will set (x-7)(x+7) equal to 0 and also solve for x.
Keep in mind that you'll be treating them as two separate equations
So, ----> (x-7) = 0 (x+7) = 0
When you solve for the x, you'll find out that x is equal to 7 and -7 ---> these are your zeros.
The answer to your queation is C
