To find the circumference of a circle you use the formula, C=2*pi*radius or C=pi*diameter, in his case you would use the first option, C=2*pi*radius, because the radius is the given value. You then plug the values into the equation to solve for the circumference...
C=2*pi*15
C=30*pi
C=30pi or approximately 94.2478
Answer:
None.
Step-by-step explanation:
4(x-1)-x = 3(x+5)-11
4x-4-x=3x+15-11
we combine like terms.
4x-x-4=3x+14
3x-4=3x+14
we then isolate the variables.
3x-4=3x+14
+4 +4
3x=3x+18
-3x -3x
0≠18
No solutions
16x11 which equals 176 so that’s the area

Answer:
vertex = (- 1, - 4 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - 
y = x² + 2x - 3 ← is in standard form
with a = 1, b = 2 , then
x = - 
= - 1
Substitute x = - 1 into the equation for corresponding value of y
y = (- 1)² + 2(- 1) - 3 = 1 - 2 - 3 = - 4
vertex = (- 1, - 4 )
