The value of h is exactly the axis of symmetry. So when h changes, it completely changes the line of symmetry. This is because the vertex is (h, k) and the x value of the vertex is always equal to the line of symmetry in a quadratic.
Changing the k value does nothing to the line of symmetry. This is because it is just moving the graph up and down, which doesn't change the symmetry of a parabola.
Answer:3.42
Step-by-step explanation:to get the answer to a area equation you need to multiply the length by the width.
Answer: 300 km
12.5/1.25 = 10 liters of fuel
10 • 30 = 300 km
<u>3x + 6y = 12</u>
Subtract 3x from each side: 6y = -3x + 12
Divide each side by 6 : <em> y = -1/2x + 2</em>
Answer:
The ratio of area of larger circle to area of smaller circle is 4:1
Step-by-step explanation:
Area of circle A=πr², d(diameter) = 2r(radius)
Area of larger circle = πR²
Area of smaller circle = πr²
Diameter of larger circle = 2 diameter of smaller circle
D =2 d
2R =2*2r
2R = 4r divide by 2
R =2r
Area of larger circle = πR²=π(2r)² = π*4r²
Area of smaller circle = πr²
π*4r²/ πr² =4/1
