Answer:
<u><em>C. strong negative</em></u>
Step-by-step explanation:
The reason why is because, the student's grade is falling dramatically while they watch TV. So therefore, we can erase A and D. B maybe however, it isn't "weak" but it is a heavy decrease. Therefore, your answer would be C.
Answer:
The gcf of 56 and 16 is 8.

Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2
Since cosa=adjacent side / hypotenuse
cos45=1/√2
We can rationalize the denominator by multiplying numerator and denominator by √2
√(2)/2
or if you prefer: √(1/2)
Add the balance and allotment:
22.90 + 50.00 = 72.90
This is how much she can actually spend.
She spent 85.50.
Subtract the two:
85.50 - 72.90 = 12.60
Since she spent more than she actually could be balance would be a negative number.
The balance would be - $12.60
The equation that represents the <em>sinusoidal</em> function is ![x(t) = -8 + 6.5 \cdot \sin \left[\left(\frac{2}{3} \pm \frac{4\cdot i}{3}\right)\cdot t + \left(\frac{2\pi}{3} \pm \frac{7\pi \cdot i}{3} \right)\right]](https://tex.z-dn.net/?f=x%28t%29%20%3D%20-8%20%2B%206.5%20%5Ccdot%20%5Csin%20%5Cleft%5B%5Cleft%28%5Cfrac%7B2%7D%7B3%7D%20%5Cpm%20%5Cfrac%7B4%5Ccdot%20i%7D%7B3%7D%5Cright%29%5Ccdot%20t%20%2B%20%5Cleft%28%5Cfrac%7B2%5Cpi%7D%7B3%7D%20%5Cpm%20%5Cfrac%7B7%5Cpi%20%5Ccdot%20i%7D%7B3%7D%20%20%5Cright%29%5Cright%5D)

<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 , .
