You draw the reference angle of 45° but clockwise. The exact value of sin(-345°) is 1/√2.
Answer:
D. (2, 0)
Step-by-step explanation:
The solutions are the two points of intersection of the graphs:
(-2, -4) and (2, 0)
The latter of these corresponds to choice D, the one you have marked.
Answer:
1={5 and 3} 2={0} 3={0.209 and 4.791} 4={-3 and 4} 5={1 and 9} 6={-4.303 and -0.697}
Step-by-step explanation:
Your probably confused on what a, b, and c means.
The problems are written like this.

That formula finds the zeros.
For example 1:

Then use the formula

If plus then 5, if minus then 3
CHECK:

Hope this helps you understand how to do this by yourself. Now to do the rest ;-;
A) a customer would pay $1.60 for 1 pound of apples. (To solve, plug in “1” for “p” and find c))
B) 8.5 pounds of apples would cost $13.60. (To solve, plug in 8.5 for p and find c)
C) If a customer pays $5.20, they will have purchased 3.25 pounds of apples. (To solve, plug in 5.2 for c and solve for p)
Have a great day!
