Answer: 6
Step-by-step explanation:
You need 12 square roots of 1764 ?
Why not find the square root of 1764 first (it's 42) and then take 12 of those ?
We will have the following:
First, we write the both equations: the line and the circle:
This can be seeing as follows:
Now, we determine the point where the line intersects the circle in the first quadrant, so first, we determine the positive part of the circle, that is:
Now, we equal this expression and the line:
From this, we take the positive value, since it the only one that makes sense under the parameters required, now we find the value of y:
So, the solution is at the point:
This can be seeing as follows:
Step-by-step explanation:
For x = 1
(1)
For x = -3,
(2)
For x = 3,
(3)
Let's add Eqn(2) and Eqn(3) together to eliminate b:
(4)
Next, multiply Eqn(1) by 3 and then add to Eqn(2) to get
(5)
Then we want to eliminate c by multiplying Eqn(4) by -2 and then adding to Eqn(5) and we will get
Now that we have the value for a, we can use either Eqn(4) or Eqn(5) to solve for c and we will get
Using the values of a and c on Eqn(1), we find that so therefore, our function f(x) has a form
