Answer:
Equation of circle in standard form with centre (0, – 10) and radius 6.
Step-by-step explanation:
We need to write equation of circle in standard form with centre (0, – 10) and radius 6.
The equation of circle is:
where (h,k) is centre of circle and r is radius
We are given centre (0,-10) so, h=0, k=-10 and radius r = 6
Putting values and finding equation:
So, equation of circle in standard form with centre (0, – 10) and radius 6.
Angle 1 + angle 6 is equal to 180° because they are on the same line.
so if angle 6 is 125° so angle 1 is:
180 - 125 = 55° :)))
i hope this is helpful
have a nice day
45 degrees, you are cutting the right angle in half
Answer:
See attachment.
Step-by-step explanation:
The given system is
The first line is already graphed.
We want to graph
We can do this by plotting two points and drawing a straight line through them.
When we choose x=0, we substitute into the equation and solve for y.
So we plot (0,-4)
Also, when y=0, we substitute and solve for x.
So we plot the point (-4,0)
We now use a straight edge to draw a straight line through these two points to obtain the graph shown in the attachment.
The mean is

you have to add all them together
2046+971+3113+1850=7980
then you divide it by 4 because there are 4 numbers and you are left with
