Answer:
C.
Step-by-step explanation:
To find slope using coordinates, use the formula above.
Now, using the formula, plug in
as
(slope) and either coordinate as the
and
values. It looks like this:
To solve for , continue to use PEMDAS.
Now use and
to solve for your equation:
The answer is C.
Answer: They are not perpendicular because their slopes are not negative reciprocals.
Step-by-step explanation:
For these two lines to be perpendicular, their slopes have to be negative reciprocals.
Slope of FG.
F = (-4, 1)
G = (0, -2)
= (Y₂ - Y₁) / (X₂ - X₁)
= (-2 - 1) / (0 + 4)
= -3/4
Slope of HJ
J = (0 , 4)
H = (-4, -2)
Slope = (Y₂ - Y₁) / (X₂ - X₁)
= (-2 - 4) / (-4 -0)
= 6/4
= 3/2
<em>The slopes of these lines are not negative reciprocals so these lines are not perpendicular. </em>
The formula for the lateral surface area of a right circular cone is:
where r is the radius of the base, and l is the slant height.
Plugging in the values we get:
where r is the radius of the base, and l is the slant height.
Plugging in the values we get:
