A given term in a PG =a₁rⁿ⁻¹

Let' calculate the 1st term a₁, knowing a term & the common factor/ratio

a₄ = 1/2 so 1/2 = a₁(1/2)³

1/2 = a₁/8 and a₁ = 4

Now calculate a₉ =a₁.r⁸

a₉ = 4.(1/2)⁸ and a₉ = 1/64

**Answer:**

inches.

**Step-by-step explanation:**

The question gives the central angle and radius of an arc and is asking for the length.

- The radius is the same as the length of the windshield wiper: 15 inches.
- The central angle is 150°.

An arc is part of a circle. What is the circumference of a circle with a radius 15 inches?

inches.

However, this wiper traveled only a fraction of the circle. A full circle is . The central angle of this arc is only . As a result,

.

The length of the arc will thus be

.

In other words, the windshield wiper traveled approximately 39.3 inches.

**Answer:**

125 every hour

1 hour = 125

2 hours = 250

3 hours = 375

4 hours = 500
