Answer:
Center (-2 , 4)
Step-by-step explanation:
x^2 + 4x + y^2 - 8y = - 11
(x^2 + 4x + (4/2)^2 + (y^2 - 8y + (8/2)^2 ) = - 11 + 4 + 16
(x + 2)^2 + (y - 4)^2 = 9
Center (-2, 4)
About 6 times. 6.4 to be exact!
the area A of the cross section of the column is 
.
<u>Step-by-step explanation:</u>
Here we have , building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π, pi meters. We need to find What is the area A of the cross section of the column .Let's find out:
We know that , Circumference of circle = 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
We know that area of circle = 
⇒ 
⇒ 
⇒ 
Therefore , the area A of the cross section of the column is .
- if you're looking for the inverse of it is -3x + 12
- if you're looking for the slope of it is m equals m=-1/3
- if you're looking for the access interception point of it is the x-intercept is (12, 0 )the Y intercepts is (0,4)
