For geothermal energy
-Pros: No cost fluctuations determined by gas and oil prices.

-Cons: Fewer installers than standard HVAC and thus less competition.

For hydroelectric
-Pros: Facilities can affect land use, homes, and natural habitats in the dam area

-Cons: Hydropower does have environmental impacts.

QUICK ANSWERS PLEASE!!

Answer:

Explanation:

GIven: an isosceles trapezoid ABCD with AD = 28, BC = 12, and BE = 9.

We can see that triangle BEA is a right triangle, so let's use the Pythagorean Theorem to solve for length AB.

To use the Pythagorean Theorem, we need the lengths of both legs. But we only have one! So let's solve for AE.

$28-12=16\\\frac{16}{2} =8\\AE = 8$

Now we know the lengths of both legs of right triangle BEA, so let's use the Pythagorean Theorem to solve for the hypotenuse, AB!

Pythagorean Theorem: $a^{2} +b^{2} =c^{2}$ where $a$ and $b$ are the legs and $c$ is the hypotenuse.

$a^{2} +b^{2} =c^{2}$

$8^{2} + 9^{2} =c^{2}$

$64 +81=c^{2}$

$145=c^{2}$

$\sqrt{145} =c$

$c$ ≈ $12$

Please answer please. I am in need of your help. NASA says the sun’s gravitational force keeps the planets in orbit, why do astr

Black_prince [1.1K]

$f_{gravity(sun)} = \frac{ g \times m_{sun} m_{astronaut} }{ {(distance \: to \: sun)}^{2} }$
$f_{gravity(earth)} = \frac{ g \times m_{earth} m_{astronaut} }{ {(distance \: to \: earth)}^{2} }$

me
consider the mass of the earth and the mass of the sun. then consider the distance between the astronaut and the sun.

you will see that the force of the Earth's gravity is much greater due to the formula above as the very large distance from the sun
