Coordinates after 270 clockwise rotation is (-6,-2), (-3,-5) and (-8, -5).
<h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given coordinates are: (-2,6) , (-5, 3) and (-5, 8)
For 270° clockwise about the origin, we have the following rule:
(x, y)= (-y, x)
So,
coordinates (-2,6) change into (-6,-2)
coordinates (-5, 3) change into (-3,-5)
coordinates (-5, 8) change into (-8, -5).

By evaluating the quadratic function, we will see that the differential quotient is:

<h3>
How to get (f(2 + h) - f(2))/h?</h3>
Here we have the quadratic function:

Evaluating the quadratic equation we get:

So we need to replace the x-variable by "2 + h" and "2" respectively.
Replacing the function in the differential quotient:

If we simplify that last fraction, we get:

The third option is the correct one, the differential quotient is equal to 8 + 4.

Answer:
-3/4
Step-by-step explanation:
Perpendicular slopes are reciprocal opposites of the original slope. This means that the reciprocal of 4/3 is 3/4, and the opposite of 3/4 is -3/4.

We are given
height = 3.7 mi
radius = 3959 mi
We are asked for the distance between the man and the horizon
The straight line from the man to the horizon is a tangent line to the surface of the earth
Using Pythagorean theorem
(3.7 + 3959)² = 3959² + d²
Solve for d
d = 171 mi
