Ln x + ln (x + 1) = ln 56

Mathematics
1 answer:
Leni [432]4 years ago
3 0

Answer:

x=7

Step-by-step explanation:

ln x +ln(x+1)=ln 56

ln x(x+1)=ln 56

so x(x+1)=56

x^2+x-56=0

(x+8)(x-7)=0

x= -8 or x=7

and lnx,x>0

so x=7

The point (5,-6) lies on a circle and the center of the circle is at the point (5,-8).
mario62 [17]

Answer:

A.  

(x - 5)^2 + (y + 8)^2 = 4

Step-by-step explanation:

The equation for a circle in center radius form is

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

We need to determine the radius, from the two points which is the distance

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

  = sqrt( (5-5)^2+( -8--6)^2)

  = sqrt(0+ (-8+6)^2)

  = sqrt( 0+(-2)^2)

  = sqrt(4)

  = 2

The radius is 2 and the center is (5,-8)

(x-5)^2 + (y--8)^2 = 2^2

(x-5)^2 + (y+8)^2 = 4
