If you draw the circle and divide into 4 quadrants, you can see that the sine is negative, since the quadrant is situated in the negative part of YY', and that the cosine is positive, since the quadrant is situated in the positive part of XX'.
And

, and negative divided by positive gives a negative answer, which means that the tangent is negative on the quadrant IV.
Hope this helps :)
Answer:
one 40% discount
Step-by-step explanation:
lets use 100$ total for an example.
Say we have 40% of 100 so the total would be 60$ but it we have 20% and then another 20% off that we would have a final total of 64$\
Prove: 100*.4=40 100-40=60
100*.2=20 100-20=80, 80*.2=16 80-16= 64$
Answer:
This was already asked
Step-by-step explanation:
Answer is 4 lb.,12 oz. As one pound has 16 ounces. When we convert the given 5 lb. into ounces we multiply it by 16. 5 lb = 5 x 16 oz 5 lb = 80 oz When we subtract 4 oz from 80 oz We get 80 - 4 = 76 oz Which is 64 oz + 12 oz (16 x 4) oz + 12 oz Which will be 4 lb. + 12 oz So the answer will be 4 lb., 12 oz.

Answer: Second option.
Step-by-step explanation:
The Slope-Intercept form of the equation of the line is:

Where "m" is the slope of the line and "b" is the y-intercept.
You know that the second equation of the System of equations given in the exercise is:

Then, you need to solve for the variable "y" in order to write it in Slope-Intercept form. The steps are:
1. Apply the Distributive property and simplify:

2. Now subtract 6 from both sides of the equation:

3. Subtract
from both sides of the equation:

4. Subtract
from both sides:

5. Divide both sides by -2:
