Scientists need to know how gravity acts on space shuttles so they can put the space shuttle in orbit. They use an equation that

patriot [66]

The equation is a scientific law, Newton's Law of Gravity,

$F =\dfrac{GMm}{r^2}$

This is a pretty bad question. Newton's Law of Gravity is a mathematical model of gravitation, originally a theory, verified by observation, and now superseded by the General Theory of Relativity.

C is probably the best answer to this poor question.

Combine the radicals. 3√5-8√5+2√5

weeeeeb [17]

Answer: $-3\sqrt{5}$

-3 times the square root of 5

=============================================

Explanation:

Let $x = \sqrt{5}$

Replace all the root 5 terms with x and we go from

$3\sqrt{5}-8\sqrt{5}+2\sqrt{5}$

$3x-8x+2x$

From here, combine like terms to get

$3x-8x+2x = -5x+2x = -3x$

and the last thing to do is replace the x with sqrt(5)

$-3x = -3\sqrt{5}$

Meaning that,

$3x-8x+2x = -3x$

$3\sqrt{5}-8\sqrt{5}+2\sqrt{5} = -3\sqrt{5}$
