check the picture below.

$\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ h(t)=\stackrel{\stackrel{a}{\downarrow }}{-16}t^2\stackrel{\stackrel{b}{\downarrow }}{+100}t\stackrel{\stackrel{c}{\downarrow }}{+12} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)$

$\bf \left( -\cfrac{100}{2(-16)}~~,~~12-\cfrac{100^2}{4(-16)} \right)\implies \left( \cfrac{25}{8}~~,~~12+\cfrac{625}{4}\right) \\\\\\ \left(\cfrac{25}{8}~,~\cfrac{673}{4} \right)\implies \left(\stackrel{\stackrel{\textit{took this long}}{\downarrow }}{3\frac{1}{8}}~~,~~\stackrel{\stackrel{\textit{went this high}}{\downarrow }}{168\frac{1}{4}} \right)$

The radius of Earth is about 6378 km, and the radius of Mercury is

Fofino [41]

In this case, Earth and Mercury are both spheres. The formula for volume of sphere is 4/3(pi)(radius)(radius)(radius).

Since the volume of both is immense, it is hard to describe here.

The concept to solve this problem would be to insert the appropriate radius length hence find the difference between the two spheres.

PLEASE HELP!!! 50 POINTS!! WILL GIVE BRAINLIEST!!!

kolbaska11 [484]

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.
