Answer:
16
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here the sum is 2520, thus
180° (n - 2) = 2520 ( divide both sides by 180 )
n - 2 = 14 ( add 2 to both sides )
n = 16
The polygon has 16 sides.
Answers:
x intercept is (-7.5, 0)
y intercept is (0, 5.5)
=========================
How to get these answers:
Simply look at where the graph crosses the x axis to determine the x intercept. This is directly halfway between the -8 and -7, so the line crosses through -7.5 on the x axis meaning that the x intercept is located at (-7.5, 0)
Similarly, the y intercept is (0, 5.5) as it crosses exactly halfway between the 5 and 6 on the y axis.
Any point is of the form (x,y)
The x intercept always has y = 0. The y intercept always has x = 0.
Note that the equation of the circle is
(x-h)² +(y-k)² =r²
where centre is (h,k)
the equation of the circle based on the information given
(x-3)² +(y-4)² =r²
and the point on the circle (3,-2)
substitute into the equation
(3-3)² +(-2-4)² =r²
r=6 or r=-6
since r is radius, we reject r=-6 since radius must be nonnegative.
the radius is 6
Answer:
1/3
Step-by-step explanation:
Slope is rise over run.
Pick a point and count how many steps up and how many steps to the right you need to make to get to the next point. That's how you find slope.
I wanna say 10 or ether -10 since if it was subtracted from 2 then it would equal -8
