Answer:
y = -0.2x - 5.8
Step-by-step explanation:
If a line is given in the form y = mx + b, the "m" is the slope.
For the line given y = 5x, the slope is 5
The line that is perpendicular to this will have slope that is "negative reciprocal of that".
So, the perpendicular line will have slope of
So, the Perpendicular Line will have equation:
y = -1/5x + b
Let's find b by replacing x with 6 and y with -7 [the point given]. So we have:
So the equation of perpendicular line = y = -0.2x - 5.8
Answer:
Step-by-step explanation:
we know that
The lateral area of the cone is equal to
where
r is the radius of the base
l is the slant height
we have
Applying the Pythagoras Theorem find the slant height
substitute in the formula
