Drag expressions to show the steps to create an equivalent expression using only positive exponents. Let g and h be two nonzero

Liula [17]

Equivalent expressions are expressions that have the same value.

The equivalent expression of $g^{-3}h$ is: $\frac{h}{g^3}$

The expression is given as;

$g^{-3}h$

Apply law of indices to change the exponents

$g^{-3}h = \frac{1}{g^3}h$

Express as products

$g^{-3}h = \frac{1}{g^3} \times h$

Rewrite as

$g^{-3}h = \frac{h}{g^3}$

Hence, the equivalent expression is: $\frac{h}{g^3}$

suppose a laser beam directed toward the visible center of the moon misses its assign target by 30 seconds . How far in miles fr

oksian1 [2.3K]

Answer:

Approximately 600 miles

Explanation:

There are several ways to solve this using different assumptions.

First you need to imagine an isosceles triangle formed by:

the equal sides of the triangle are the distance between the Earth and the Moon: 234,000 miles

the included angle is 30 second of degree

the base side of the triangle, opposed to the 30 seconds angle, is how far in miles from its assigned target the laser beam is: x

You can solve for x in several ways.

I will use the cosine rule:

$c^2=a^2+b^2-2accos(\alpha)$

Where:

$c=x\\\\a=234,000miles\\\\b=234,000miles\\\\\alpha=30seconds$

One second of degree equals 1/3600 degrees:

$30seconds\times 1degree/3600seconds=1/120degrees$

Substitute in the equation and compute:

$x^2=(234,000miles)^2+(234,000miles)^2-2(234,000miles)(234,000miles)\times cos(1/120\º)$

$x=579.15mile\approx600miles$
