First of all, let's recall that the full circumference is
Now, since 30 is one twelfth of 360, a 30° arc will be one twelfth of the whole circumference. So, if you call the arc length A, you have
Since we know the arc length, we can build and solve the following equation:
Step-by-step explanation:
f, your friends lunch
f + 3, your lunch
f + f + 3 = 19
2f + 3 = 19
2f = 16
f = 8
Your friends lunch was $8
I hope this helped!!!!
Subtract 2c from both sides
5c-25-2c=2c+6-2c
3c-25=6
add 25 to both sides
3c-25+25=6+25
3c=31
Divide both sides by 3
3c/3=31/3
c=31/3
hope this helps!
The general or standard form of a parabola is
(y-k) = a(x+h)^2
h,k are the intersection points of parabola
Intersection points are where y= 0, or x=0
itsnorigin at (,0,0)that means h=0, k=0
it passes through points (-1,2) and (1,2)
So then
y= ax^2 , 2 = a (-1)^2
this means a= 2
Then results standard form equation
Y = 2• X^2
