To find the height of the diver above the ocean after 2 seconds using the formula \( h(t) = 75 - 16t^2 \), we need to substitute \( t = 2 \) into the equation.
Given:
\[ h(t) = 75 - 16t^2 \]
Substituting \( t = 2 \):
\[ h(2) = 75 - 16(2^2) \]
Calculating \( 2^2 \):
\[ 2^2 = 4 \]
Now substituting back into the equation:
\[ h(2) = 75 - 16(4) \]
Calculating \( 16 \times 4 \):
\[ 16 \times 4 = 64 \]
Now substituting this value back:
\[ h(2) = 75 - 64 \]
Finally, performing the subtraction:
\[ h(2) = 11 \]
Therefore, the diver is 11 feet above the ocean after 2 seconds.
