a tennis ball dropped on a surface takes a sequence of bounces, each one 1/2 as high as the preceding one. if this ball is dropped at a height of 10 feet, what is the total height it would have traveled when it hits the surface the sixth time?​

Hey bby was a good way i just got

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

de+df> ef (option 54 is false); de+ef> df (option 1 is true); ef+df> de.

substitute sides lengths:

4+9> ef ⇒ ef< 13; 4+ef> 9 ⇒ ef> 5.

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
