Answer:

See below

Step-by-step explanation:

In order to derivate the cofunction identity, we will use the difference identity for sine.

[tex]\boxed{\sin(\alpha-\beta ) =\sin(\alpha )\cos(\beta ) - \cos(\alpha )\sin(\beta ) }[/tex]

[tex]\sin \left(\dfrac{\pi}{2} - x\right) =\sin \left(\dfrac{\pi}{2}\right)\cos(x) -\cos\left(\dfrac{\pi}{2}\right) \sin(x)[/tex]

Once

[tex]\sin \left(\dfrac{\pi}{2}\right) = 1[/tex]

[tex]\cos\left(\dfrac{\pi}{2}\right) = 0[/tex]

[tex]\sin \left(\dfrac{\pi}{2} - x\right) =1 \cdot \cos(x) -0\cdot \sin(x)[/tex]

[tex]\sin \left(\dfrac{\pi}{2} - x\right) = \cos(x)[/tex]

Answer:

True

Step-by-step explanation:

The ratio would be 1:2, which means for every unshaded part there's 2 shaded parts. Looking at the pie chart, we can tell that there are 2 unshaded and 4 shaded. This can mean there are 2:4 unshaded to shaded. Reduced, we get 1:2

The required retail cost of the hat before the markup is 11.73.

Given that,
Monty buys hats in bulk to sell at his store. His cost for each hate is $17. He marks up the hats 45%. What is the retail price per hat is to be determined.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

here,
Let the retail cost be x,
According to the question, the retail price is markup by 45%.
So the cost after mark up = x + 0.45x = 1.45x
And
17 = 1.45x
x = 17 / 1.45
x = 11.73

Thus, the required retail cost of the hat before the markup is 11.73.

Answer:

Step-by-step explanation:

Hey :)

Keep in mind:

y = mx + b

Where m = slope and b = y-intercept

Since we are told:

y = 9x - 3

This means m = 9 and b = -3

Therefore the slope is 9 and y-intercept is at (0,-3)

Answer:

2x+90°+x°=180

or, 2x+x=180-90

or, 3x= 90

or, x= 90/3

or, x= 30°

Therefore , the value of X is 30°.

Thank you ☺️☺️☺️

Answer:

x=30

Step-by-step explanation:

2x+90+x+90+90=360

Combine like terms

3x+270=360

Subtract 270 from both sides

3x=90

Divide both sides by 3

x=30

Answer:

The second one

Step-by-step explanation:

The true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

A number system is defined as a system of writing to express numbers.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

The given inequality is x>-3.

The value of x should be greater than -3.

The value -3 is not included.

In a number line the values are increased from left to right.

As x is greater than -3 which means the x values are increasing from left to right.

So the statement open circle on -3 and all numbers to the right shaded is true statement.

Hence,  the true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

The slope of y = 2x - 5 is 2. Parallel lines have the same slope, so the slope of the line through the given points A and B is also 2. This means

(8 - 4) / (6 - n) = 2

Solve for n :

4 / (6 - n) = 2

4/2 = 6 - n

2 = 6 - n

n = 6 - 2

n = 4
