Answer:
The diameter is: d = 5m
Step-by-step explanation:
We know that
Circumference of Circle = 2πr
Given that
The circumference of a circle = 5π
so the equation becomes
Circumference of Circle = 2πr
5π = 2πr
2πr = 5π
r = 5π/2π
r = 5/2 m
As we know that:
The diameter is twice the radius. i.e. d = 2r
Thus, the diameter is:
d = 2(5/2)
= 5 m
Therefore, the diameter is: d = 5m

Answer:
x =8
Step-by-step explanation:
To answer this question you must find the point at which
So, we have:
To solve the quadratic function we use the quadratic formula
±
Where:
Then:
The line cuts the parabola by 2 points, x = -1.472 and x = 7.47.
You can verify that between x = -1.472 and x = 7.47. the line is greater than the parabola, but from x = 7.47, the parabola is always greater than the graph of the line.
Therefore the point sought is:
x = 7.47≈ 8
Answer:
It might depend on theorem.
Step-by-step explanation:
Sometimes you should make a value possibly important to the theorem a variable. So if the theorem says something like the inner angle of something is always twice the outer angle of another shape, try making the inner angle x and then seeing if you get 2x for the other, since it means that, regardless of what x equals, the other angle is twice it.
Hello from MrBillDoesMath!
Answer:
-17 or 32, depending upon the value of the symbol before "11".
First answer (-17) if symbol interpreted as +; second answer (32) if symbol interpreted as "/"
Discussion:
The equation you wrote uses a division sign. The original, I believe, uses a plus sign instead. Not sure which one to use so let's solve both of them.
Interpretation 1:
2 (4^2 + 3) - 66 + 11 =
2( 16+3) - 66 + 11 =
2(19) -66 + 11 =
38 -66 + 11 =
= -17
Interpretation 2:
2 (4^2 + 3) - 66 \ 11 = => order of operation, "\" before "
2(19) - 6 =
38 - 6 =
32
Thank you,
MrB
