Find the value of x.

  x = 9

Step-by-step explanation:

Triangle BCD is a right triangle, so the inscribed angle at C is the complement of the given angle:

  angle C = 90° -45° = 45°

The measure of arc BE is twice that angle value, so we have ...

  arc BE = 2·angle C

  10x° = 2(45°)

  x = 9 . . . . . . . . . divide by 10°

0.5 meters per second

step-by-step explanation:

the average speed between 2 seconds and 8 seconds is 0.5 meters per second.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :
