If the height of an object at time t can be represented by
h(t) = -16t2 + 38t + 9, find h(7).

-509

Step-by-step explanation:

h(t) = -16t² + 38t + 9

h(7) = - 16(49) + 38(7) + 9

h(7) = -784 + 266 + 9

h(7) = -509

Solution:

It should be noted:

To find h(7), let's find "t" by comparing h(7) and h(t).

Compare h(7) and h(t):

Now, find h(7) by substituting the value of t into the equation.

Substitute the value of t into the equation:

Thus, h(7) is -509.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
