To find the number of feet the cliff-diver is above the ocean after 2 seconds, we can use the given formula:
\[ h(t) = 75 - 16t^2 \]
where \( h(t) \) is the height in feet after \( t \) seconds.
Now, substitute \( t = 2 \) into the formula:
\[ h(2) = 75 - 16(2^2) \]
Calculate \( 2^2 \):
\[ 2^2 = 4 \]
Now substitute this back into the equation:
\[ h(2) = 75 - 16(4) \]
Now, calculate \( 16 \times 4 \):
\[ 16 \times 4 = 64 \]
Now substitute this value back into the equation:
\[ h(2) = 75 - 64 \]
Now, perform the subtraction:
\[ h(2) = 11 \]
Therefore, the diver is 11 feet above the ocean after 2 seconds.
