Answer:
A.
Step-by-step explanation:
C = 2πr = πd
A. C = π(38.5 in.) = 120.95 in.
First guess: Answer: A.
Treat it like a fraction
18b^2/45b
divide top and bottom by b
18b/45
divide top and bottom by 3
6b/15
divide top and bottom by 3 again
2b/5
2b:5 is the simpliest form of the ratio
Answer: The sum is 3.
Step-by-step explanation:
If we have a parabola, y = a*x^2 + b*x + c
We want to find the point (x, y) that corresponds to the vertex of that parabola.
The vertex of the parabola is at x value:
x = -b/2a
in this case
a = 1, b = 0, c = 3
then our vertex is at:
x = -0/2*1 = 0
Now we evaluate y(x) in this value and get:
y(0) = a*0^2 + 3 = 3
Then the vertex is at the point (0, 3)
the sum of the coordinates of the vertex is:
S = 0 + 3 = 3
Answer:
2
Step-by-step explanation:
The Fundamental theorem of algebra states that a polynomial of degree n has n roots. These can be real or complex.
A quadratic is of degree 2 and has 2 roots.
6m^2-3mn+6 is the answer.
