Sin²t +cos²t =1

<span> x=2+3 sin t
sin t=(x-2)/3

</span><span>y=1-1/2cos t
y-1= - (cos t)/2 
cos t =-(y-1)/(1/2)

</span>(x-2)²/3² + (y-1)²/(1/2)² = 1

The table below shows the amount paid for different numbers of items. Determine if this relationship forms a direct variation. V
Elden [556K]
<h2>Answer/Step-by-step explanation:</h2>

Direct variation occurs when a variable varies directly with another variable. That is, as the x-variable increases, the y-variable also increases.

The ratio of between y-variable and x-variable would be constant.

Direct variation can be represented by the equation, y = xk, where k is a constant. Thus,

\frac{y}{x} = k

From the table given, it seems, as x increases, y also increases. Let's find out if there is a constant of proportionality (k).

Thus, ratio of y to x, \frac{0.50}{1} = 0.5

k = 0.5.

If the given table of values has a direct variation relationship, then, plugging in the values of any (x, y), into \frac{y}{x} = k, should give us the same constant if proportionality.

Let's check:

When x = 2, and y = 1:

\frac{y}{x} = k,

\frac{1}{2} = 0.5,

When x = 3, y = 1.5:

\frac{1.5}{3} = 0.5,

When x = 5, y = 2.50:

\frac{2.5}{5} = 0.5,

The constant of proportionality is the same. Therefore, the relationship forms a direct variation.

The average rate of change from x = 0 to x = 15 is about −4.667. How does the average rate of change from x = 0 to x = 20 compar
Amanda [17]
First we calculate the ambio rate from x = 0 to x = 15:
 We have:
 R = ((80-10) / (0-15))
 R = -4.666666667
 We now calculate for the entire interval:
 from x = 0 to x = 20:
 R = ((80-2) / (0-20))
 R = -3.9
 Answer:
 What is the average rate of change over the entire slide?
 R = -3.9
 The average rate of change from x = 0 to x = 15 is about -4.667. How does the average rate change from x = 0 to x = 20 compare to this number?
 The percentage difference is:
 (-3.9 / -4.666666667) * (100) = 83.57142857%
 100-83.57142857 = 16.42857143%
