To find the number of feet the diver is above the ocean after 2 seconds using the formula \( h(t) = 75 - 16t^2 \), we will substitute \( t = 2 \) into the formula.
-
Start with the equation: \[ h(t) = 75 - 16t^2 \]
-
Substitute \( t = 2 \): \[ h(2) = 75 - 16(2^2) \]
-
Calculate \( 2^2 \): \[ 2^2 = 4 \]
-
Now multiply by 16: \[ 16 \cdot 4 = 64 \]
-
Substitute this back into the equation: \[ h(2) = 75 - 64 \]
-
Finally, calculate: \[ h(2) = 11 \]
Thus, the diver is 11 feet above the ocean at \( t = 2 \) seconds.
