From the top of a tall building, a gun is fired. the bullet leaves the gun at a speed of 340 m/s, parallel to the ground. as the drawing shows, the bullet puts a hole in a window of another building and hits the wall that faces the window. using the data in the drawing, determine the distances (a) d and (b) h, which locate the point where the gun was fired. assume that the bullet does not slow down as it passes through the window.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
