We have been given that you drop a ball from a window 50 metres above the ground. The ball bounces to 50% of its previous height with each bounce. We are asked to find the total distance traveled by up and down from the time it was dropped from the window until the 25th bounce.
We will use sum of geometric sequence formula to solve our given problem.
, where,
a = First term of sequence,
r = Common ratio,
n = Number of terms.
For our given problem , and .
Therefore, the ball will travel 100 meters and option B is the correct choice.
Answer:
300
Step-by-step explanation:
I t is good
It would be FH
A diameter is basically the length of the line through the centre that touches 2 points on a circles edges
84 is divided into 7 84/7 =12
and it is added to
9 divided into 3 9/3 =3
12+3=15
Answer:
∠A = ∠D (**but very important Δ ABC has to be congruent to Δ DEF)
Step-by-step explanation:
It will help if you draw the triangles out and label the same sides. Then according to the side-angle-side (SAS) rule, ∠A should be equal to ∠D
