First put the words in an algebraic format or a model. D = 3.5(√H). Now determine what the question is asking. It's height. Plug in the value of D. Distance is 35 km.
35 = 3.5(√H) We want to get H by itself. First thing to get away from it is 3.5. So divide 35 by 3.5 And 3.5(√h) by 3.5.
10 = √H To get rid of √ do the opposite raise to the power of 2
10² = (√H)²
100 = H
You must be 100 kilometers above ground to see 35 kilometers
Answer:
Solution By Gauss jordan elimination method
x = 3, y = 2 and z = 4
The girls are closer. Her feet are 1/2 the distance away from the surface pool, the boys are 3/4 away.
just move the 15 the left and divide 5 and u should get c=3
