Answer 1

I think it's the 3rd one going down. The A(n) = 1.5 • (0.74)n-1 ; 0.33 cm

Answer 2

Answer: Second option is correct.

Step-by-step explanation:

Since we have given that

Height of ball = 1.5 meters = 150 cm

Each curved path has 74% of the height of the previous path.

so, r = 74% = 0.74

Since initial height is n = 1.

As it form Geometric series.

So, the general equation would be

$A(n)=ar^{n-1}\\\\A(n)=150(0.74)^{n-1}$

We need to find the height of the ball at the top of the sixth path .

So, n= 6,

So, it becomes,

$A(6)=150(0.74)^{6-1}=150(0.74)^5=33.285\approx 33.29\ cm$

Hence, Second option is correct.
