Brzycki's formula is used by weight lifters to determine the weight M that is equivalent in a single repetition to n repetitions of a weight w. The formula is M = w 1.0278 − 0.0278n. It applies for up to n = 10 repetitions. In this exercise we consider a weight lifter who bench-presses several repetitions of w = 270 pounds. (a) What single bench press weight M corresponds to 9 repetitions of this weight? (Round your answer to two decimal places.) M = lb (b) What number of repetitions n of this weight corresponds to a single bench press of 277.72 pounds? (Round your answer to the nearest whole number.) n = repetitions

Question
Brzycki's formula is used by weight lifters to determine the weight M that is equivalent in a single repetition to n repetitions of a weight w. The formula is
M =
.
| w |
| 1.0278 − 0.0278n |
It applies for up to
n = 10
repetitions.
In this exercise we consider a weight lifter who bench-presses several repetitions of
w = 270 pounds.
(a) What single bench press weight M corresponds to 9 repetitions of this weight? (Round your answer to two decimal places.)
M = lb
(b) What number of repetitions n of this weight corresponds to a single bench press of 277.72 pounds? (Round your answer to the nearest whole number.)
n = repetitions
M = lb
(b) What number of repetitions n of this weight corresponds to a single bench press of 277.72 pounds? (Round your answer to the nearest whole number.)
n = repetitions
