Answer:
a, a, d
Step-by-step explanation:

The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
Here b = 10 and h = 9 , then
A = × 10 × 9 = 5 × 9 = 45 in² → a
45
The area (A) of a parallelogram is
A = bh ( b is the base and h the perpendicular height )
Here b = 2 and h = 4 , then
A = 2 × 4 = 8 m² → a
46
A = bh ( with b = 4 and h = 10 )
A = 4 × 10 = 40 m² → d
Answer:
Geometric sequence
=54(2/3)^(n-1)
Step-by-step explanation:
Given that a ball is bounced and get up and again hits the ground and bounces up, and so on.
The first height after first hit = 54 inches
Next second peak = 36 inches
III peak = 24 inches
The second peak is 2/3 of first height
and third peak is 2/3 of second height
Thus there is a pattern of geometric sequences such that each peak is 23 of initial peak
IN general nth peak = 54(2/3)^(n-1)
Mean is 30,median is 30.5,mode is 31.
