Answer:
The yellow one
Step-by-step explanation:
If you're solving for g then move all terms to the left side and set equal to zero. Then set each factor equal to zero.
And your answer becomes 
If you're solving for r then then move all terms to the left side and set equal to zero. Then set each factor equal to zero and your answer is 
Answer: The amplitude is 4.
Step-by-step explanation:
Given the form of the sine function:

Where
is the amplitude,
is the period and "k" is the vertical shift of the wave.
You know that, in the sine function given (
), you can identify the amplitude and the period. These are:


Therefore, the amplitude of
is:

Answer:
60
Step-by-step explanation:
Since this angle is unknown, let's just represent it with the variable "x". So the supplement angle of "x" is essentially, the value of the angle that we need to add to "x" to get 180. In other words let's just say that the supplement angle is "y". This means that:
. If we subtract x from both sides we can represent "y" or the supplement angle as:
.
Since it's 660 less than 6 times it's own supplement let's first multiply the supplement by 6

Now let's subtract 660 from it, since it's 660 less

This value should be equal to the angle, which is represented as "x". So let's set it equal to x

Add 6x to both sides

Divide both sides by 7

Answer:
756 miles
Step-by-step explanation:
315/5=63
So, 63=unit rate.
63 times 12=756.
756 miles
