Use the graph below to answer the question that follows: trig graph with points at 0, 2 and pi over 2, 0 and pi, negative 2 and

3 pi over 2, 0 and 2 pi, 2 and 5 pi over 2, 0 and 3 pi, negative 2 What trigonometric function represents the graph?
f(x) = −2 cos(x − pi over 2) f(x) = −2 sin(x − pi over 2) f(x) = 2 cos(x − pi over 2) f(x) = 2 sin(x − pi over 2)

What trigonometric function represents the graph?

 f(x) = −2 cos(x − pi/2) 
 f(x) = −2 sin(x − pi/2 )  
f(x) = 2 cos(x − pi/2)  
f(x) = 2 sin(x −pi/2 )

Merlin wants to make more money selling fake beards this month than he did last month. All black beards in his shop cost the sam
sukhopar [10]

We know that all black beards cost the same money

And all red beards cost $25

And B represents number of black beards

And R represents number of red beards

We have been given the inequality 20B+25R > 350 to show the target for this month.

The above inequality shows that Merlin needs to make more than 350, hence he made 350 last month

Further, it shows that B has been multiplied by 20, hence the black beard's cost was 20

If x an integer and 2x +8 <22 and 3x >9, how many possible values of x are there?
koban [17]

Answer:

3 values

Step-by-step explanation:

2x +8 <22 and 3x >9

Solve the two inequalities separately and then put them back together

2x +8 <22

Subtract 8 from each side

2x +8-8 <22 -8

2x < 14

Divide by 2

2x/2 < 14/2

x < 7

Then solve the second inequality

3x>9

Divide by 3

3x/3>9/3

x >3

Putting them back together

x>3 and x < 7

Since it has to be an integer

4,5,6  are possible choices

3 values
