Answer:

y-4=-3(x-13)

Step-by-step explanation:

Once again, the point-slope formula is y(1)-y(2)=m(x(1)-x(2))

You already know the slope which is -3.

You just have to plug in (13,4)

------------------------------

45

Step-by-step explanation:

7 -sqrt(10)

-----------------------

3 sqrt(5) *sqrt(3)

7 -sqrt(10)

-----------------------

3 sqrt(15)

Multiply the top and bottom by sqrt(15)/ sqrt(15)

7 -sqrt(10)               sqrt(15)

----------------------- * ------------

3 sqrt(15)                 sqrt(15)


(7 -sqrt(10))* sqrt(15)

-----------------------------------

3 *15

Distribute


7sqrt(15) - sqrt(150)

------------------------------

45

sqrt(ab) =sqrt(a) sqrt(b)

150 = 25*6

7sqrt(15) - sqrt(25)sqrt(6)

Find the circumference of a circle with an area of 28.26.<br> Show work please.
muminat

Answer:

18.84

Step-by-step explanation:

Since the formula for circumference is C=2\pi r, we need to first find the radius. The formula for the radius is r=\frac{\sqrt{A\pi } }{\pi }, so we will get r=3. Substitute that into C=2\pi r, and we get C=18.84. Hope this helps!
