If the diameter is 18 inches, the radius is 9 inches. The formula for circumference is 2*pi*r, so it would be 2*3.14*9, so the circumference is 56.52 inches. But rounded to the nearest inch, it is 57 inches.
Answer:
the first one's answer is y > x
the first second one's answer is y < 6.5x i believe, sorry if im wrong
Step-by-step explanation:
Answer:

Step-by-step explanation:
That things are the same when they're both the same as something else is the "transitive property." It applies to many things, from interchangeable parts to math expressions to geometrical objects, as here.
When there are 3 given statements, and two of them are shown as such, it isn't hard to determine what the third one is.
The remaining blanks can be filled by the process of elimination.
Answer:
X = 96
Step-by-step explanation:
This one is pretty simple
So we're dealing with angles here.
So what we want to do is add the two angles and it =180
Here's the equation so it makes more sense:
so we'd place in those numbers
add the two angles together
than we'd subtract from 180 getting the value of X
In both cases you may well benefit from graphing the functions.
Do you recognize f(x) = (x + 1)^2 - 1 as a quadratic function, whose graph is that of a parabola that opens up? By comparing this to y = a(x-h)^2 + k, we see that a=1, h= -1 and k = -1. The vertex is at (h,k), which here is the point (-1, -1). This is the minimum value of the function. Thus, the range of this function is [-1, infinity).
Now for the function f(x) = 7x - 11: This is a linear function whose graph is (surprise!) a straight line. When x increases, y increases, without limits to either. Similarly, when x decreases, y decreases.
Thus the range includes all real numbers: (-infinity, infinity).
