A cliff is 600 ft above the ground. If an object is thrown upward from teh top of the cliff at an initial velocity of 48 feet per second, its height s after it is thrown is given by the function h(s) = -16s^2+48x+600

Step-by-step explanation:

We can find the time it takes the object to reach its max height

At the Max height dh/dx = 0

dh/dx = -32x + 48

Since dh/dx = 0

0 = -32x + 48

32x = 48

x = 48/32\

x = 1.5secs

Hence it takes the object 1.5secs to reach its max height

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

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,
