Hey there!

φ = (pi / 2) * (180 / pi) = 90

So, this would include that sense 90 is on
the on the x-axis, this would mean that this
would be (0).

Your correct answer is \boxed{\boxed{0}}

Hope this helps.

Without graphing predict weather the function y= (1/2)x shows exponential growth or decay. Justify your predictions
Alik [6]

Answer:

The base of the exponential function is 0.5 which is between 0 and 1 and thus this is an exponential decay function.

Step-by-step explanation:

Exponential equations are usually in the form;

y=ab^{x}

where;

a is the initial value, that is the value of y when x is 0,

b is the growth or decay factor and also the base of the exponential function

If b>1, then it is an exponential growth function and the values of y keep getting bigger.

if 0<b<1, then it is an exponential decay function and the y values keep getting smaller as x increases.

In the function given;

y=(\frac{1}{2})^{x}

The base of the exponential function is 0.5 which is between 0 and 1 and thus this is an exponential decay function.

In order to justify our prediction, we can simply obtain the graph of the function and check on how x and y vary.

From the attachment below we can see that the values of y become increasingly smaller as the values of x increases in magnitude which justifies our predictions.

Movie Ticket Sales : 6x + 9y = 1,500 Which graph shows this relationship?
sukhopar [10]
Ok so we have movie ticket sales and we have 6x+9y=1,500. So for types of graphs, we have linear, exponential, quadratic, and those are the basic types of graphs. Now looking at the equation, we can quickly see that the answer is linear because, looking at the constant, 1500 and the other numbers, we can see the graph will be increasing linear. Hope this helped, feel free to ask questions if you have any!

Hey guys I need some help with #7 so if anyone could help that would be great THANK YOU!!

The average rate of change obtained from the ratio of change in y to the change in x is 27

The average rate of change can be obtained using the relation :

Rate of change = (y2 - y1) ÷ (x2 - x1)

at; x1 = -3

y1 can be calculated from the function ;

y1= 3(-3³)-1

y1=-82

At ; x2 = 3

y2 can be calculated from the function ;

y2 = 3(3³)-1

y2=80

The rate of change can be calculated thus : (y2 - y1) ÷ (x2 - x1)

[80-(-82)]/[3-(-6])

162/6

27
