Question 935796: Brad threw a baseball off a cliff. The height h, of the ball, in feet, is modeled by the function below, where t represents time, in seconds, after the ball has been thrown.
h(t) = -16t^2 + 48t + 50
What is the height of the baseball after 1 second?

+h%28t%29+=+-16t%5E2+%2B+48t+%2B+50+
You are asked to find:
+h%281%29+=+-16%2A%281%29%5E2+%2B+48%2A1+%2B+50+
+h%281%29+=+-16+%2B+48+%2B+50+
+h%281%29+=+82+
After 1 sec, the height of the ball is 82 ft
------------------
Here's the plot:
+graph%28+400%2C+400%2C+-1%2C+5%2C+-10%2C+100%2C+-16x%5E2+%2B+48x+%2B+50+%29+

h(1) = -16*1*1 + 48*1 + 50
h(1) = 82 feet above the zero-height reference ...
in cliff problems the zero-height reference is usually the base of the cliff
