#48 How would I do this? I don't believe my answer is right

4 0

Well you have to make the powers line up so we know r^4 is the highest and you work your way down so

0r^4-5r^3-4r^2-3r
R^4+0r^3-4r^2+3r

So now that they are lined up by power we solve (keep in mind that the 0r's are place holders and have no value)

R^4-5r^3-8r^2

That's your answer

Find the value of x.

allsm [11]

Answer:

$3 \sqrt{5}$

Step-by-step explanation:

x is the center of the circle.

the chord of length 12 can be splitted into two parts of 6 length each.

since the radius does not change when it touches another end of the circle, we can safely calculate our radius to be the hypotenuse of the triangle formed by the length of the chord and 3.
