A competitive cliff-diver jumps from a height of 75 feet. Find the number of feet the river is above the ocean in 2 seconds. Evaluate for t = 2 by using the formula 75 - 16t2, where t is time in seconds
To find the number of feet the river is above the ocean in 2 seconds, we can substitute t = 2 into the formula 75 - 16t^2.
75 - 16(2)^2 = 75 - 16(4) = 75 - 64 = 11.
So, the number of feet the river is above the ocean in 2 seconds is 11 feet.
