Hope this helps. Sorry if the expression is in the wrong form.
It is asking you to slice off 40% of the bounce height in each subsequent bounce.
So you start with full height 1, that's n = 0 bounces. Then after n = 1 bounce the new height is .6. After the second bounce, n = 2, the height becomes .6 X .6 = .36. And after n = 3, we have .6 X .6 X .6 = .216
So by induction we see that h(n = 5) = .6^n = .6^5 = 0.07776 = .078 of its original height or H = .078*200 = 15.6 ft. after five bounces. ANS. 16.0 if rounded to the nearest tenth
:)
To complete the problem (5.2 - 4.5) - 5.5(4.8) you have to start with solving the numbers inside of the ( )'s.
Once you do this you should get .7 - 5.5(4.8).
Then you need to multiply to get .7 - 26.4.
Now all you have to do is simplify, -25.7
There you go! If you have any more questions about this or anything else just let me know! ;)
3x + 12 - 5x = 22
-2x + 12 = 22
-2x = 22-12
-2x = 10
x = -5
hope this helps
