Answer:

112.2ft

Step-by-step explanation:

As can be seen in the attached diagram, The top of the building is at C.

The distance from the man to the building is |BD| and the height of the man is |AB| where his eye level is at B.

We are required to find the height |CE| of the building.

Now |AB|=|DE|, (opposite sides of a rectangle).

Tan 65° = |CD|/59

|CD|=59 XTan65°=107.23

The height of the building |CE|=|CD|+|DE|=107.23+5=112.23ft

The height=112.2ft ( to the nearest tenth)

Arrange these functions from the greatest to the least value based on the average rate of change in the specific interval
oee [108]
The average r. of c. of a function f(x) on an interval [a,b] is:

  f(b) - f(a)
--------------
    b-a

You'll need to apply this to all four of the given functions.

First function:  f(x) = x^2 + 3x
a= -2; b= 3

Then the ave. r. of c. for this function on this interval is:

    18  - (-2)            20
------------------ = ---------- = 4.  y increases by 4 for every unit increase in x.
      3-(-2)                5

Do the same thing for the other 3 functions.

Then arrange your four results in descending order (greatest to least).

One of Eric's steps is 18in long. How many steps would he take to walk 1 mile?
Evgesh-ka [11]

Answer:

3520 steps

Step-by-step explanation:

The first thing we must do is figure out how many inches are in a mile. (There are 63,360 inches in one mile). With that out of the way, we can now divide these inches by 18, since each of Eric's steps are 18 inches long, and we want to determine how many steps he would have to take. 63,360 divided by 18 is 3520. This means our answer is 3520 steps, and that is how many steps he must take to walk 1 mile. I hope you understood and please let me know if you still need help!
