Answer:

  3√2

Step-by-step explanation:

The length of the diameter is given by the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-4))² +(8 -14)²) = √(36 +36) = 6√2

The radius is half the diameter, so the radius of your circle is 3√2.

Log (4x-1)+5=8<br><br> Please help me!
nordsb [41]

log (4x-1) + 5 = 8

log (4x-1) = 8 - 5

log (4x-1) = 3

4x - 1 = 10³

4x - 1 = 1000

4x = 1001

x = 1001/4

ok done. Thank to me :>
