Log4(2-x)=log4(-5x-18)

1 answer:

6 0

$\log_4 (2-x) = \log_4 (-5x-18)\\\\\implies 2-x = -5x -18\\\\\implies 5x -x = -18-2\\\\\implies 4x = -20\\\\\implies x = -\dfrac {20}4\\\\\implies x = -5$

The ratio of the areas of two circles is 121/100. What is the ratio of the radii of the two circles

alekssr [168]

Answer:

11/10

Step-by-step explanation:

The area ratio is the square of the radius ratio (k):

(121/100) = k²

k = √(121/100) = 11/10

The ratio of radii is 11/10.
