A cable attached to the roof of a building is 41 feet long. If the cable starts 9 feet from the base of the building, how tall is the building?

The building is 50 feet tall

Step-by-step explanation:

The building may be considered in two parts; from the roof to the start of the cable and from the start of the cable to the base of the building.

As such, if the height of the building is h, the distance from the roof to the start of the cable is y and from the start of the cable to the base of the building x then

h = y + x

Then h = 41 + 9

= 50 feet

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,
