Final answer:
The upper bound for the actual height of the cellular antenna tower is 32.15 m, considering that the height is measured to the nearest tenth of a meter.
Step-by-step explanation:
The question asks what the upper bound for the actual height of the cellular antenna tower is, given that it is measured to 32.1 m to the nearest tenth of a meter. When a measurement is given to the nearest tenth, this implies that the actual measurement can be up to half of one-tenth (0.05 m) larger than the stated measurement without rounding up to the next tenth. Therefore, to find the upper bound, we add 0.05 m to the measured height.
The upper bound for the actual height of the tower is 32.1 m + 0.05 m = 32.15 m.
