Answer:
<u />
Explanation:
Since the <em>bases</em> must not be painted, their areas are <em>not included</em> in the calculation.
The <em>surface</em> to paint, of each pillar, is equal to the lateral area of a<em> cylinder </em>with he dimensions given.
The formula for the laeral area of a cylinder is:
Substitute including the conversion factor to convert inches to feet:
Answer:
Part A) The slope is undefined
Part B) The equation of the line is
Part C) None y-intercept
Part D) The slope of a line perpendicular to the given line is equal to zero
Step-by-step explanation:
we have that
Describe
A) slope of the line
B) equation of the line
C) y-intercept
D) slope of a line perpendicular to the given line
Part A) slope of the line
we know that
The formula to calculate the slope between two points is equal to
we have
Substitute the values
-----> the slope is undefined
Its a vertical line (parallel to the y-axis)
Part B) Equation of the line
we know that
The equation of a vertical line is equal to the x-coordinate of the points through which the line passes.
so
Part C) The y-intercept
The y-intercept is the value of y when the value of x is equal to zero
The vertical line not intercept the y-axis
so
None y-intercept
Part D) slope of a line perpendicular to the given line
A line perpendicular to the given line is a horizontal line (parallel to the x-axis)
therefore
The slope is equal to zero
y = 12x represents the gallons of paint used in x hours.
Step-by-step explanation:
CJ uses 3 gallons of paint in 15 minutes,
15 minutes = 3 gallons
1 minutes =
1 hour = 60 minutes
Gallons of paint used in 1 hour;
1 hour =
CJ uses 12 gallons of paint in 1 hour.
For x hours = 12*x = 12x
Gallons of paints used = y
y = 12x represents the gallons of paint used in x hours.

Answer:
(A)
Step-by-step explanation:
From the diagram attached:
Angle 1 and Angle 6 are Co-Interior Angles.
The sum of co-interior angle is 180 degrees.
Therefore:
The measure of angle 1 is therefore 56.5 degrees.
The correct option is A.
