Answer:
B) 
Step-by-step explanation:
The formula for the area of a circle is : 
The radius of a circle is the length from one side to the centre.
To work this out you would have to multiply pi by the radius of 7 squared, this gives you 153.94, however if using pi as in 3.14, then the answer is 153.86.
1) Multiply pi by 7 squared.
You could subsitute g(x) for x in f(x) and if you get x as a result, then that is indeed the inverse
ex
if
f(x)=x-2
the inverse which is g(x) is
g(x)=x+2 because if you did
f(g(x)) then you would get
f(g(x))=(2+x)-2=2-2+x=x
Four points are always coplanar if lie on same planes because coplanar points<span> are three or more </span>points <span>which lie in the same plane.
So,The right answer is :
</span><span>D. lie in the same plane.</span>
Answer:
17, -3, -13, -18, -23
Step-by-step explanation:
Plug in the x side into the equation so
g(-4) = -5(-4) -3
g(-4) = 20-3
g(-4) = 17
Therefore that answer is 17
Then you do that for all of them, I don't have the time to do them all but that's the concept for all of them. Hope this helps and hopefully it's not too late. Sorry!
