Answer: go over 3 up 1
Step-by-step explanation: so like go to 3 then go up 1. Then go 3 more then up 1. Should be right I apologize if I’m wrong but I should be right!
Answer:
<h2>84.78</h2>
Step-by-step explanation:
We have the area of a circle

The sector with a central angle of

Calculate, what part of 360° is an angle 120°:

The same part of an area of a circle is an area of a segment.
Therefore:

Use π ≈ 3.14

Answer:
They distort differences between values.
Step-by-step explanation:
Non-zero axes distort differences between values, but they are not always misleading.
It depends on who is looking at them.
Consider the bar graphs below, showing the change in interest rates over time.
A naïve reader might conclude that interest rates had risen sharply (the zero-axis shows that they have remained steady).
However, a professional who specializes in interest rates might find the information in the left-hand graph quite useful.
Answer:
(-b/2a, b^2/(4*a) - b^2/2a + c)
Step-by-step explanation:
For a general parabola:
y = a*x^2 + b*x + c
We can write the vertex as:
(h, k)
The x-value of the vertex is the value of the axis of symmetry.
Then we have:
h = x = -b/2a
Now we need to find the y-value of the vertex.
To do that, we just replace the variable "x" by the x-value of the vertex in our equation, so we get:
k = y = a*(-b/2a)^2 + b*(-b/2a) + c
k = b^2/(4*a) - b^2/2a + c
Then the coordinates of the vertex are:
(h, k) = (-b/2a, b^2/(4*a) - b^2/2a + c)
