What is 2 to the power of 2?
padilas [110]
Okay, so you are talking about exponents, so what you are talking about is 2², to find the answer to the exponent you multiply the same number as many times as the exponent (little number) says, so in here we are going to multiply 2 x 2 and the answer is 4. So 2 to the power of 2 is 4.

PLEASE HELP ASAP! Will give brainliest if you explain
Romashka-Z-Leto [24]
Well, the best way to solve this would involve the Pythagorean theorem. 
First, take the length of the hypotenuse (the string in this case) and square it. Do the same to the side length we are given (the kites height above the ground).
We then subtract the squared height from the squared hypotenuse. We should be left with 1,781m.
All we have to do now is find the square root of 1,781m.

Your answer for b is 42.20189569m.
