A monkey is swinging from a tree. On the first swing, she passes through an arc of 20m. With each swing, she passes through an arc 54 the length of the previous swing. What is the total distance the monkey has traveled when she completes her 10th swing? Round your final answer to the nearest meter.
Q. A monkey is swinging from a tree. On the first swing, she passes through an arc of 20m. With each swing, she passes through an arc 54 the length of the previous swing. What is the total distance the monkey has traveled when she completes her 10th swing? Round your final answer to the nearest meter.
Calculate distance using formula: Calculate the distance of each swing using the geometric sequence formula.First swing = 20m,Second swing = (54)×20m=16m,Third swing = (54)×16m=12.8m, and so on.
Use geometric series formula: Use the formula for the sum of a geometric series: Sn=a×(1−rn)/(1−r), where a is the first term, r is the common ratio, and n is the number of terms.Here, a=20m, r=54, and n=10.S10=20×(1−(54)10)/(1−54)
Calculate (4/5)10: Calculate (4/5)10 using a calculator.(4/5)10≈0.1074
Substitute into formula: Substitute back into the sum formula.S10=20×(1−0.1074)/(1−54)S10=20×0.8926/0.2S10=89.26/0.2S10=446.3
Round final answer: Round the final answer to the nearest meter.Final distance ≈446 meters.
