The answer would be 10,856 because there are 10,800 seconds in three hours so you divide 12,800 by 10,846 and it will give you the cost of how much it was spent.

The number of views on an interesting video after it's uploaded is represented by the following table:

defon

Answer:

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is $,V(t)=50(6.25)^t$

Step-by-step explanation:

Time (months) Views

0 50

2 313

4 1950

6 12,210

8 76,300

10 476,800

$(x_1,y_1)=(0,50)\\(x_2,y_2)=(2,313)\\(x_3,y_3)=(4,1950)$

$Slope = \frac{y_2-y_1}{x_2-x_1}$

$Slope = \frac{313-50}{2-0}$

Slope =131.5

$Slope = \frac{y_3-y_2}{x_3-x_2}$

$Slope = \frac{1950-313}{4-2}$

Slope =818.5

Since the slope is not same . So, it is not a linear relationship

$\frac{y_2}{y_1}=\frac{313}{50}=6.25\\\frac{y_3}{y_2}=\frac{1950}{313}=6.25$

Since the ratio between the consecutive outputs is same so, it is exponential relationship.

Formula : $y=ab^t$

Where a is the initial value = 50

b = rate of change = 6.25

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data

So $,V(t)=50(6.25)^t$

If 1-cos A=1/2 then find the value of sinA.

Aneli [31]

Step-by-step explanation:

$1 - \cos( \alpha ) = \frac{1}{2} \\ = > \cos( \alpha ) = 1 - \frac{1}{2} = \frac{1}{2} \\ = > \alpha = arccos( \frac{1}{2} ) =60 {}^{ \bullet} = \frac{\pi}{3} \\ then \\ \sin( \frac{\pi}{3} ) = \frac{ \sqrt{3} }{2}$
