Answer:
<em>Standard form: </em><em></em>
<em>A = 12, B = 3 and C = -2</em>
<em></em>
Step-by-step explanation:
Given:
The equation:
To find:
The standard form of given equation and find A, B and C.
Solution:
First of all, let us write the standard form of an equation.
Standard form of an equation is represented as:
A is the coefficient of x and can be positive or negative.
B is the coefficient of y and can be positive or negative.
C can also be positive or negative.
Now, let us consider the given equation:
Multiplying the whole equation with 3 first:
Now, let us take all the terms on one side:
Now, let us compare with .
So, <em>A = 12, B = 3 and C = -2</em>
Answer:
4.5 inches
Step-by-step explanation:
We are given the formula:
V =
Plug in the the radius (3) and volume (127.23):
127.23 =
Square the 3 :
127.23 =
Multiply the pi & volume:
127.23 = 28.26h
Divide both sides by 28.26:
127.23 ÷ 28.26 = 28.26h ÷ 28.26
h = 4.5021231...
I hope this helps!
