Answer
4.8 x 10^-3
Step-by-step explanation:
Given:
The system of equations is


To find:
The true statement about the given system of equations.
Solution:
The slope intercept form of a line is

Where, m is the slope and b is the y-intercept.
We have,


On comparing these two lines with slope intercept form, we get


Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.
Therefore, the correct option is A.
Answer:
3.14
Step-by-step explanation:
Lines A and B are parallel. Lines A and B apre perpendicular to Line C.
Change all of the lines from standard form to slope-intercept.
Line A: y = 4/3x + 2/3
Line B: y = 4/3x + 2
Line C: y = -3/4x + 1
Since A and B have the same slope they are parallel. C has a negative reciprocal so it's perpendicular.
Cylinder area=height times area of base (area of base=area of circle)
height =1.8
radius=6.1
area of circle=pi times r^2
area of circle=pi times 6.1^2=37.21π
times height
1.8 times 37.21π=66.978π
volume=66.978π ft^3
