Option C: The sum of the infinite geometric series is

Explanation:

The sum of infinite geometric series can be determined using the formula,

Substituting the values and in the above formula, we have,

Simplifying the denominator by taking LCM.

Thus, we have,

Simplifying, we get,

Multiplying, we get,

Thus, the sum of the infinite geometric series is

Hence, Option C is the correct answer.

C

Step-by-step explanation:

Sum = a/(1 - r)

= 5/(1 - ⅓)

= 5/(⅔)

= 5 × 3/2

= 15/2

= 7.5

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
