Ya Motha
Step-by-step explanation:
Answer: A
Step-by-step explanation:
The first thing we need to do is to make sure our equation is in standard form. The given equation is not in standard form.
3x²-2x=0
Now that the equation is in standard form, we can find our A, B, C to see which quadratic equation is correct.
A=3
B=-2
C=0
We can automatically eliminate D because the first value is -3 when it is supposed to be -(-2). Also, the denominator is supposed to be 2a. We know that A=3. The denominator should be 2(3), not 2(-2).
Next, we can eliminate B and C. For the 4ac, we know it has to be 4(3)(0) because A=3 and C=0. B and C have given 4(3)(2) and 4(3)(1), respectively. This does not match A=3 and C=0.
Therefore, A is the correct answer.
Answer:
Distance: 8
Step-by-step explanation:
d = sqrt [(x-x)^2 + (y-y)^2]
d = sqrt [(4-4)^2 + (-4-4)^2]
d = sqrt(0) + (-8)^2
d = sqrt 64 = 8
Answer:
The radius of this circle is
and the central angle of the sector is
.
Step-by-step explanation:
Consider the provided information.
If a conical paper funnel is made out of a sector of circle then the radius of the sector becomes the slant height of the cone, and the length of the curved part of the sector becomes the circumference of the base of the cone.
First find the slant height: 



Thus, the radius of the sector is
which is same as the slant height of the cone.
Now, the circumference of the base of the cone is same as the length of the curved part.


The length of the curved part = 



Hence, the radius of this circle is
and the central angle of the sector is
.
