You drop a ball from a height of 1.5 meters. Each curved path has 74% of the height of the previous path. a. Write a rule for the sequence using centimeters. The initial height is given by the is term n = 1.
b. What height will the ball be at the top of the sixth path?

1) A(n) = 1.5 • (0.74)^x-1; 0.33cm
2)A(n) = 0.74 • (1.5)^x-1; 5.62cm
3) A(n) = 150•(0.74)^x-1; 33.29cm
4) A(n) = 150 • (74) ^x-1; 332,850,993,600cm

Step-by-step explanation:

Given

--- initial

--- rate

Solving (a): The rule of the sequence

First convert to centimeters

The equation is then calculated using the following geometric progression formula

This gives:

Express percentage as decimal

Solving (b): The height on the 6th path

This implies that:

So, we have:

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
