We can convert the logarithmic equation to exponential equation to find its equivalent equation.

y= log_{ \frac{1}{2} }(x) \\  \\ 


Shifting the base of log(1/2) to the other side of the equation, we can write:

(\frac{1}{2})^{y} =x \\  \\ 
x= \frac{ 1^{y} }{ 2^{y} }  \\  \\ 
x= \frac{1}{ 2^{y} } \\  \\ 
x= 2^{-y}

This problem has to do with Fahrenheit and Celsius
Vinvika [58]
F = 1.8C + 32

С = -10   ⇒   F = 1.8·(-10) + 32 = 14   ⇒   (-10, 14)
С = 0      ⇒   F = 1.8·(0) + 32 = 32      ⇒   (0, 32)
С = 10    ⇒   F = 1.8·(10) + 32 = 50    ⇒   (10, 50)
С = 20    ⇒   F = 1.8·(20) + 32 = 68    ⇒   (20, 68)

What is the greatest common factor of 20 and 30???
Ugo [173]
The greatest common factor of 20 and 30 is 10. This is because 10 is the largest number that when it is used to divide 20 or 30, it equals a whole number.

The simple way for us to solve is to write down the factors of both numbers, find the factors that match for both numbers, and see which is the largest out of those that match.

20: <u>1</u>,<u>2</u>,4,<u>5</u>,<u>10</u>,20
30: <u>1</u>,<u>2</u>,3,<u>5</u>,6,<u>10</u>,15,30

Using that logic, we can see that 10 is the greatest factor that the numbers share.

30 Points please help!! Please explain too!
sergiy2304 [10]
Initial: 200 feet = opp. side
Angle = 17.31, adj. Side = a
So tan (17.31) = opp. Side / adj. Side
tan (17.31) = 200 / a
--> a = 200/tan17.31 = 641.73
When stopped: adj. Still = a
Opp. Side still = 200, angle = 46.41
tan46.41 = 200 / a
--> a = 200/tan46.41 = 190.39
Now subtract those two distances to get the distance traveled from initial to when it stopped:
641.73 - 190.39 = 451.34 feet
