Length of the diameter = sqrt ( (-12- (-8)^2) +(2-0)^2) )
= sqrt (16 + 4) = sqrt20
so radius = sqrt 20 / 2 = sqrt5
so r^2 = 5
Center of the circle = coordinates of the midpoint of the diameter =
-8-12/2 , 2-0 / 2 = (-10, 1)
(x - a)^2 + (y - b)^2 = r^2 is general form of a circle so here the circle is:_
(x + 10)^2 + (y - 1)^2 = 5 Answer
Its B
Answer:
1.16
Step-by-step explanation:
Answer:
609
Step-by-step explanation:
All you must do is multiply 1450 by 0.42. That would give you the total.
Answer:
Where
Step-by-step explanation:
To find:
The equation of the given graph in the question area.
Solution:
By looking at the graph, we can clearly see that the graph is either sine curve or cosine curve.
We know that sine curve starts at 0.
Therefore, the given curve is sine curve.
Let us have a look at the different values of a sine curve at various angles.
Also,
Here, we have at , it means that angle is in the form of .
Now, let us have a look at the curve is decreasing or increasing.
It is decreasing after the angle 0, therefore the function has a negative sign.
So, it can be written as:
Now, let us have a look at the maximum and minimum values so as to find the value of
Here, we can clearly see that minimum value is -2 and maximum value is 2.
Therefore, the value of is 2.
So, the equation is:
Where
This I think could be technically answered in a couple of ways. Fill the 4 gallon bucket up and then fill the 7 gallon bucket up 1/7 of the way. Or fill the 4 gallon bucket up and transfer to the 7 gallon bucket and fill the 4 gallon bucket up 1/4 of the way. Either way the 1/4 or the 1/7 will be a close estimate to get your 5 gallon bucket. I hope this helps.
