Concentric circles are circles that share a common center with each other.
There are 3 circles in this diagram. There is a circle with center A, a circle with center B, and a circle with center C. There are no circles that share the same center, as all circles have their own centers.
There are no concentric circles shown.
The correct answer is: 2x+3y=24
The largest number in the chart is 45, so the person left 45 minutes after 10:30 a.m. That person left the library at 11:15 a.m.
Answer:
53
Step-by-step explanation:
The other missing angle looks like a right angle making it 90, so to find x you would subtract 90 and 37 from 180 (because every triangles angles should add up to 180) so it would look like this: 180- (37+90)= x.
Answer:
(f º g) = 
Step-by-step explanation:
So it's important to note that the notation: "(f º g)" isn't f(x) * g(x), it's a composite function, where you essentially have two functions, with one of the functions being the argument of one of the functions.
This means we can plug in the function g(x) as x into the function f. So let's do that
Original Function:
f(x) = -1x + 1
Plug in x^4 (this is the value of g(x)) as x into the function
f(g(x)) = 
Distribute the negative sign
f(g(x)) =
