Answer:
y= 3x
Step-by-step explanation:
The slope is just read. It is 3. It is the value of m in the general equation.
y = mx + b
y = 3x + b
To find b, use (-1,-3)
x = -1
y = -3 Substitute into the general equation
-3 = 3(-1) + b Simplify the right side
-3 = -3 + b Subtract -3 from both sides
b = 0
Answer: y = 3x
The length of an arc length can be calculated using the formula:
s = ra
where s is the lenght of the arc
and r is the radius of the circle
a is the central angle in radians
first converts degrees to radians
a = 60 ( pi / 180)
a = pi /3 =1.05
s = 21(1.05)
s = 22 mm is the length of the arc
Answer:
I think it's a c and d sorry if I'm wrong
Answer:
162°
Step-by-step explanation:
To find the measure of an interior angle in a regular n-gon, we use the formula:
(n - 2)(180) / n
We substitute 20 in for n to get:
(20 - 2)(180) / 20
And simplify:
(18)(180) / 20
(18)(9)
162°
