<h3>Answer: Choice C -- (0.6, 1.9)</h3>

Explanation:

Look through the table to see where f(x) and g(x) are the same value. Unfortunately this never happens for any row. However, we can get fairly close when we look at row two with f(x) = 1.8 and g(x) = 2; this input is x = 0.6

A good guess is that the midpoint of 1.8 and 2 is the y coordinate of the solution, so this is where the 1.9 comes from. You add 1.8 and 2 to get 3.8, then divide in half to get 1.9

So when x = 0.6 a good guess at the y value of the solution is y = 1.9, meaning that (0.6, 1.9) is an estimate of the solution

note: this is likely not the true solution, but it may be fairly close

Whats the radius for the circle? x^2+2x+y^2+4y-6=0

MAXImum [283]

Answer:

r = $\sqrt{11}$

Step-by-step explanation:

So we need to complete the square for both parts of the equation

First though we can add the 6 to the other side so we have x² + 2x + y² + 4y = 6

So first we can complete the square for x² + 2x

To do so we need to use $(\frac{b}{2} )^{2}$ to figure out the number we need to add to both sides

In this case our b is 2, so substituting this in we get $(\frac{2}{2} )^{2} =(1)^{2} =1$

Here we add 1 to both sides and now we have x² + 2x + 1 + y² + 4y = 6 + 1

Now we can follow the same steps to complete the square for y² + 4y

Here our b is 4, so substituting this in we get $(\frac{4}{2} )^{2}=(2)^{2} =4$

Now we add 4 to both sides and now we have x² + 2x + 1 + y² + 4y + 4 = 6 + 1 + 4

Now condensing everything we have (x + 1)² + (y + 2)² = 11

The formula for a circle is (x - h)² + (y - k)² = r²

In our equation we have r² = 11

To find the radius we need to take the square root of both sides $\sqrt{r^{2}} =\sqrt{11}$ to get r = $\sqrt{11}$
