Answer:
4 Hours
Step-by-step explanation:
38 - 10 = 28
28 / 7 = 4
For this case we have the following function:
y = 1/4 (x + 2) ^ 2 - 7
We derive the equation:
y '= 1/2 (x + 2)
Equaling zero we have:
1/2 (x + 2) = 0
We clear the value of x:
x + 2 = 0
x = -2
Answer:
The equation of the axis of symmetry for the parabola is:
x = -2
Figures of same shape and size are similar .Two circles C1&C2 will be similar.
Circle 1 has a center of (-4,5) and circle 2 has a center of (2,1) .The x of the center is having the translation x+6 and the y is having a translation of y-4.The center of the circle is dilated by 3 units.
The circles are similar because you can translate Circle 1 using the transformation rule (x+6,y-4 ) and then dilate it using a scale factor of 3.
2) Area of sector =
÷360.
Where α is the angle made at center.
Area of given sector= π(12)(12)(60)÷360 =24π.
