Answer:

A is the correct one

cause according to function rule the vertical line should cut only on a one point to be function

as here we can see that vertical line cuts here at two point

A mountain climber is standing at the top of Mount Everest. The distance from the summit to the horizon is 210 miles. About how

igor_vitrenko [27]

Let DE, the height of mount Everest be x.

The center of the earth (point C), the horizont vanishing point (point H) and the top of mount Everest (point E) form a right triangle, where:

the hypothenuse is |EC|=|ED|+|DC|=x+4000 (DC is a radius)
|HC|=4000 mi
|HE|=210 mi

by the Pythagorean theorem:

$(x+4000)^{2}= 4000^{2} + 210^{2}$

$(x+4000)^{2}=16000000+44100=16044100$

taking the square roots of both sides we get:

$x+4000=+- \sqrt{16044100} =+-4005.5087$

so x=-4000+4005.5087 miles = 5.5087 miles
or x= -4000-4005.5 which is negative so not a solution to our problem

Answer: 5.5087 miles

Vertical plane R intersects horizontal plane P. Points A, D, and B are on the line of the intersecting planes. Point F is on the

mariarad [96]

The true statements are:

Points A, B, and D are on both planes.
Point H is not on plane R.
Points C, D, and A are noncollinear.
The line containing points F and G is on plane R.

<h3>What is the intersection of 2 planes?</h3>

If two planes are said to have intersect each other, the intersection will be regarded as a line.

Hence, looking at the image attached, you will see that Points C, D, and A are noncollinear and the line containing points F and G is on plane R.

Note that when a line and a plane are said to intersect each other , the intersection will be a single point, or say a line. So Points A, B, and D are on both planes.

Therefore, option 1, 2, 4 and 5 are correct.
