A competitive cliff-diver jumps from a height of 75 feet. Find the number of feet the diver 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 diver is above the ocean in 2 seconds, we substitute t=2 into the formula 75−16t2.
75−16(2)2
75−16(4)
75−64
= 11
Therefore, the diver is 11 feet above the ocean after 2 seconds.
To find the number of feet the diver is above the ocean in 2 seconds, we can substitute t = 2 into the formula 75 - 16t^2 and evaluate it.
Replacing t with 2 in the formula:
75 - 16(2^2)
Simplifying the equation:
75 - 16(4)
75 - 64
Evaluating the expression:
75 - 64 = 11
Therefore, the diver is 11 feet above the ocean after 2 seconds.
To find the number of feet the diver is above the ocean after 2 seconds, we can substitute t=2 into the formula 75−16t2, where t is time in seconds.
Step 1: Start with the formula 75−16t2.
Step 2: Replace t with 2, as we want to evaluate it for t=2.
75−16(2)2
Step 3: Simplify the calculation inside the parentheses.
75−16(4)
Step 4: Multiply 16 by 4.
75−64
Step 5: Subtract 64 from 75.
11
Therefore, the competitive cliff-diver is 11 feet above the ocean after 2 seconds.
