Answer: C
y=-5cos(x) is the graphed equation. Cos(x) starts at (0,0) and one period is 2pi or 6.28 and by cos(x) multiplied by -5 starts the cosine wave at (0,-5) and thus corresponds to the graphed equation shown.

Answer:
2x-3 < 7 = x ≤ 5 and 5 - x ≤ 8 = x ≥ - 3
Step-by-step explanation:
Answer:
(4x−7)⋅(3x+5)
Step-by-step explanation:
Its that because of the steps that you learn
Assuming each employee works 40 hours a week:
3 * 20.93 * 40 = 2511.60
7 * 19.68 * 40 = 5510.40
13 * 23.00 * 40 = 11960.00
2511.60 + 5510.40 + 11960.00 = $ 19,982.00
The calculator rounded the answer.
The exact value of is , i.e. a zero followed by infinitely many 6s.
The calculator can store only 4 decimal digits, so it has to approximate the number. By doing so, it has to "choose" between 0.6666 and 0.6667.
Since the next digit is a 6, the approximation is 0.6667.
In fact, if you have to approximate with four decimal digits, you have to look at the fifth. If it is between 0 and 4, you use your fourth digit. For example, 0.35742 is approximated by 0.3574.
If instead the fifth digit is between 5 and 9, you raise the fourth digit by one: 0.57836 is approximated by 0.5784
