Apirate shoots a cannonball into the air from a height of 10
feet with an initial vertical velocity of 160 feet per second. use
the vertical motion model, h = –16t+ vt + s, where v is
the initial velocity in feet per second and s is the height in feet,
to calculate the maximum height of the cannonball. round your
answer to the nearest tenth if necessary.

We are basically given most of what we need to calculate the height of the cannonball.

We use the formula h = –16t+ vt + s to find the height requested.

Let v = 160

Let s = 10

Let t = time in seconds

Was the value of t included? We need to know t to plug into our formula.

You know everything else except for t. Go back to your notes to search for t. Afterward, plug the value of t and everything else given above into the formula and calculate to find h.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

correct answer is b. 27/8
