Pizza is great, yes very good
2/5=m/70
Use cross multiply
70*2=5*m
140=5m
Divided 5 to each side
140/5=5m/5
m=28
Check:
2/5=m/70
Substitute m with 28
2/5=28/70
2/5=4/10
2/5=2/5. As a result, m=28. Hope it help!
Answer:
<u> (x-1)^4 + (y-4)^2 = 25 </u>
Step-by-step explanation:
Center at 1,4 means the circle is of the form:
(x-1)^4 + (y-4)^2 = r^2
Find r^2 using distance formula from center to the given point
r ^2 = ( 8-4)^2 + (4-1)^2
r^2 = 16 +9 = 25
so you answer is <u> (x-4)^4 + (y-8)^2 = 25 </u>

The smallest degree of rotation is called the angle of rotation. This can be calculated by dividing the angle of full rotation by the number of sides of a regular polygon. Since a full rotation is 360 degrees, we divide 360 by 24.
Thus, the smallest rotation needed to map the polygon back to itself is 15 degrees.
we can conclude that the measure of a negative angle coterminal with 4л/3 is B = -2л/3
<h3>How to find the coterminal angle?</h3>
For a given angle A, we define the family of coterminal angles as:
B = A + n*2л
Where n is an integer number.
In this case, we want to find a negative coterminal angle to A = (4л/3), then we can replace it in the above formula to get:
B = 4л/3 + n*2л
Now we just need to find a value of n such that B is negative, if we select n = -1, then:
B = 4л/3 - 2л = 4л/3 - 6л/3 = -2л/3
Then we can conclude that the measure of a negative angle coterminal with 4л/3 is B = -2л/3.
