Answer:
14
Step-by-step explanation:
Let's find (f-g)(x)

Now let's plug in x=2, so to find (f-g)(2)

answer:
x=-4/7 and the slope is 7
Answer: 
Step-by-step explanation:
Substitute the value of the radius of the Earth into the formula given in the problem, where r is the radius, to obtain the surface area of the Earth:

The problem says that the dry land forms 29.2% of the Earth’s surface, therefore, multiply the surface area by 
Threfore, the area of dry land is the following:

The ordered pairs are (1,-1) (1,-2) (2,-3) (2,-4).
This is not a function because in order to be a function, every x value needs to have one and only one y value. You can see here that the x values have two y values, so it is not a function.
Answer:
30.2
Step-by-step explanation:
cos(58) = 16/BC
BC = 16/cos(58) = 30.2
