A^2 + 2^2 = 10^2
A^2 + 4 = 100
A^2 = 96
A = square root of 96 - about 9.8 m

C)
Step-by-step explanation:

Answer:
5 (probably not right i havent done this type of math in a long time)
Step-by-step explanation:
<span>-16x^3+4x=0
-4x(4x^2 - 1) = 0
-4x(2x+1)(2x - 1) = 0 (factor using a^2 - b^2 = (a+b)(a-b))
-4x = 0; x =0
2x +1 = 0;x = -1/2
2x - 1 =0; x = 1/2
answer: x = 0, x = 1/2 and x = -1/2</span>
