The expression that represents the value of sin C - cos C is s-r
From the triangle ABC, since sin B = r and cos B = s.=, hence;
- Opposite side= r
- Adjacent side = s
- Hypotenuse = 1
If m<C is the reference angle, then;
Opposite side= s
Adjacent side = r
Hypotenuse = 1
Sin C = s and cos C = r
Hence the expression that represents the value of sin C - cos C is s-r

Answer:
Step-by-step explanation:
Based on the two graphs I see at the bottom of the photo, you're looking at a quadratic function. The answer you put in is a linear equation.
Quadratic functions follow the form
, where a, b, and c can be either positive or negative constants.
The table says that the equation, when graphed, should start at the top, slide to the bottom, and then slide back up to the top. So a must be positive.
c has to be -8 since it's the y-intercept.
So far, our equation is
. We'll need to plug in some points in order to work out what
and
are.
Let's use
as the first set of points, and
as the second set.

Now we have 2 equations with 2 unknowns. Solve for one variable:

Now substitute that into the second equation:

Now substitute the result into the first equation.

Now substitute our values back into the original equation:

Please let me know if this is correct.
Answer:
Step-by-step explanation:
Y = 0:

0 is neither prime nor composite.
y=1:

3 is a prime number (because only 3 and 1 divide evenly into it)
y = 2:

8 is a composite number (because multiple different numbers divide evenly into it: 1, 2, 4, and 8)
Answer:
positive, it doesnt have a negative sign duh!
