Answer:
Arc AB= 180 degrees
Arc BC= 15 degrees
Arc CA= 165 degrees
Step-by-step explanation:
In order to find the measure of each arc, start by recognizing that a circle equals 360 degrees, and the measure angle of the diameter of this circle is equal to half of 360 degrees, which is 180 degrees.
Since segment AB is the diameter of the circle, it will equal 180 degrees. Thus, causing arc AB equal to 180 degrees.
Next, arc BC equals 15 degrees because the measure of angle BOC is equal to the measure of arc BC.
Then, to find the measure of arc CA, use the diameter of the circle, which is segment AB. Segment AB is equal to 180 degrees, which makes arc AB equal to 180 degrees. Also known is the measure of arc BC, which is 15 degrees. To find the measure of arc CA, subtract the measure of arc BC from the measure of arc AB, and the answer will be 165 degrees.
This looks like 180 degrees - 15 degrees = 165 degrees.
To check if the arc measures are correct, add all the arc measures together. If they sum up to 360 degrees, then the measure of each arc is correct.
The answer to the question
believe what you're asking is to turn the trinomial into two binomials
So you first have to get 3x²; the only way to get this is
(3x )(x ) when multiplying that, you would get 3x²
when dealing with the -8x and the 4, you must find numbers that are factors of four (when multiplied together they will equal 4) and will multiply with the x's to get -8
(3x-2)(x-2)
you can tell that this is the answer because when you multiply though you will get:
3x-2x²-6x+4
or: 3x²-8x_4
Hope this helped
Something to the second power is simply that number multiplied by itself once. The third power is something multiplied by itself 2 times, and so on
Answer:
The vertex is (-3,-2)
Step-by-step explanation:
We can write the equation for a parabola in the form
y = a(x-h)^2 +k where (h,k) is the vertex
y =-2 (x - 3)^2 - 2
h = -3 and k =-2
The vertex is (-3,-2)
