Answer:
208.8 mi
Step-by-step explanation:
Form a triangle with the centre of the Earth (C) at one point, the horizon (H) as a second point, and the top of Mt. Everest (O) as the third (see diagram).
Let
r = Earth’s radius
h = height of Mt Everest
d = distance to horizon
∆CHO is a right triangle.
d² + r² = (r+h)²
d² + 3959² = (3959+5.5)²
d² + 15 673 681 = 3964.5²
d² + 15 673 681 = 15 717 260 Subtract 15 673 681 from each side
d² = 43 579 Take the square root of each side
d = 208.8 mi
The distance from the top of Mt Everest to the horizon is 208.8 mi.

I JUST TOOK THE TEST THE ANSWER IS CORRECT.
Step-by-step explanation:

A. slope: 3, y-intercept: –9
B. slope: –3, y-intercept: 9
C. slope: 1, y-intercept: –3
D. slope: 9, y-intercept: –3
The slope and y-intercept of the given line are -3 and 9 respectively.
The general equation of a line in two variables of the first degree is represented as Ax + By +C = 0, A, B ≠ 0 where A, B and C are constants which belong to real numbers.
When we represent the equation geometrically, we always get a straight line.
Given that, an equation of a line y = -3x+9, we need to determine the slope and the y-intercept of this line,
The slope of a line tell about the steepness and the y-intercept tells the point where it intersects the y-axis,
The slope-intercept form of the equation of a line is given by ;
y = mx+c
Here, m is the slope and c is the y-intercept,
So, the given equation is y = -3x+9
Comparing with the slope-intercept form,
m = -3 and y-intercept = 9
Hence, the slope and y-intercept of the given line are -3 and 9 respectively.

Step-by-step explanation:
If you square an integer, there is no way to get a negative as a result.
Let's look at -5².
-5² means -5 × -5 or 25.
6² means 6 × 6 or 36.
So, there is no way to end up with a negative.
