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]

sin, cos, 1, 0, cos

Step-by-step explanation:,,

Answer:

The answer is B:subtract 1,add x,divide by 4

The other answer is D:add x,subtract 1,divide 4

Step-by-step explanation:

when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3

the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=[tex]\frac{3}{4}[/tex]

The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=[tex]\frac{3}{4}[/tex]

With that evidence I can reasonably say that answer to the question is B,and D

Answer:

A wall can be built by 6 men working 8*5*6=240 hours.

If 4 men works 5 hours a day, they work 20 hours/day.

It will take them 240 hours /20 hours = 12 days

Answer:

Step-by-step explanation:

Let J = John's share ($)

     P = Peter's share ($)

     H = Henry's share ($)

1) H = P + 80

2) J/P = 6/3 = 2

3) P/H = 3/5  

Substitute equation 1) into equation 3)

P/(P + 80) = 3/5            (multiply both sides by (P + 80)

P = (3/5)*(P + 80)         (multiply both sides by 5)

5*P = 3*P + 240

2*P = 240

P = 240/2 = $120

Substitute P value into equation 2)

J/P = 2  or

J = 2*P = 2*$120 = $240

John received $240

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)

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.

Answer:

3(x+16)= 4x-8

x=56

Step-by-step explanation:

3(x+16)= 4x-8

use distributive property

3x+48=4x-8

add 8 to each side

3x+56=4x

subtract 3x from 4x

56=x

check work

3(56+16)=4(56)-8

distributive property again

168+48= 224-8

add the left side

216=224-8

subtract the right side

216=216

Therefore , the value of X is 30°.

Thank you ☺️☺️☺️

Answer:

x=30
