h(t) = -0.81(3.0864)^2 + 5(3.0864)

Question

h(t) = 4.938

Answer 1

To evaluate the expression h(t) = -0.81(3.0864)^2 + 5(3.0864), we first need to calculate the value of (3.0864)^2:

(3.0864)^2 = 9.52519056

Now, substitute this value into the equation:

h(t) = -0.81(9.52519056) + 5(3.0864)

Now we simplify the equation:

h(t) = -7.7162323456 + 15.432

Finally, combine like terms:

h(t) = 7.7157676544

Therefore, the value of h(t) is approximately 7.716.
