For the wooden box, if you do 7560 ÷ 180 you get 42. that's how many boxes you would need. multiply 42 by the cost of the wooden boxes: 42 × 0.70 you get 29.40 dollars
for the plastic container, do 7560 ÷ 126 which equals 60, the amount of plastic containers you would need. multiply 60 by the plastic containers cost: 60×40= 24 dollars.
to save money, the company should use the plastic containers because it costs less than the wooden ones.
The equation that represents the <em>sinusoidal</em> function is , .
<h3>Procedure - Determination of an appropriate function based on given information</h3>
In this question we must find an appropriate model for a <em>periodic</em> function based on the information from statement. <em>Sinusoidal</em> functions are the most typical functions which intersects a midline () and has both a maximum () and a minimum ().
Sinusoidal functions have in most cases the following form:
(1)
Where:
- - Angular frequency
- - Angular phase, in radians.
If we know that , , , and , then the sinusoidal function is:
(2)
(3)
The resulting system is:
(2b)
(3b)
By applying <em>inverse trigonometric </em>functions we have that:
, (2c)
, (3c)
And we proceed to solve this system:
,
By (2c):
The equation that represents the <em>sinusoidal</em> function is , .

Since the 6 in 629,470 is larger than 4 than you would round up.
hope it helps!
(0, 3) so b = 3 and slope = -5/4
equation
y = -5/4x + 3
answer
B. y = -5/4x + 3
