Step-by-step explanation:

Alright, archtan /

tan

−

1

(

x

)

is the inverse of tangent. Tan is

sin

cos

. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.

Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.

Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.

Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

Which TWO expressions are equivalent to (x - y) 2/3 - 3/4 (y-x)

Answer:

For number one I forget what it is called but I know that its not right because the left side can't be connected to 2 numbers on the right side. For number 3 I honestly have no idea I have never seen or done that equation in my life. For number 4 all you have to do is count up then how many left or right that goes to the line crossing a place where a point could be. For example you rise 3 and go over two it would be 3/2. Though that isn't the answer I hope this helps. Also I don't know number 8 either I am sorry but I also hope this helped a little bit.

Easiest way to solve this is to probably grab a piece of paper and just add 17 until you find whatever you’re looking for!

Answer:

$17.94

Step-by-step explanation:

Step one:

given

the cost price of snow globes = $9.20

mark up percent= 95%

Required:

the retail selling price

Step two:

let us find 95% of $9.20

=95/100*9.20

=0.95*9.20

=$8.74

Hence the retail selling price is = 9.20+8.74

=$17.94

Answer:

Yes you are right.

Step-by-step explanation:

Once you divide 128.25 by 3 you will get 42.75

Then you multiply 42.75 by 5 and you will get 213.75.

Answer:

The height is 8

Step-by-step explanation:

Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.

Make the equation.

[tex]\frac{2}{3} = \frac{x}{12}[/tex]

Now isolate x (in order to solve for it)

[tex]12 * \frac{2}{3} = \frac{x}{12}*12\\8 = x[/tex]

x= 8

The height is 8.

8/12 = 2/3 ✅

Answer:

Small flags = 108

large flags= 47

Step-by-step explanation:

Step one:

given

let the number of small lag be x

and big flags be y

so

3.5x+6.5y= 683.5----------1

x+y=155------------------------2

Step two:

from eqn 2 x= 155-y

put x= 155-y in  eqn 1

3.5(155-y)+6.5y= 683.5

542.5-3.5y+6.5y=683.5

collect like terms

3y=141

divide by 3

y= 141/3

y=47

Step three:

put y= 47 in eqn 2

x+47=155

x= 155-47

x=108

Answer:

1800 = 1950 - m

Step-by-step explanation:

Lets call the fixed amount he withdraws every month m. He starts with $1950 and withdraws a certain amount, m, every month. At the end of the first month, he has withdrawn 1m amount of money and ends up with $1800. Therefore, 1950 - 1m =  1800. We can get rid of the 1 and get 1950 - m =  1800, or 1800 = 1950 - m. If the answer choices do not have "m" as a variable, you can substitute "m" for any variable.

(4x² - 2x - 3) + (-3x² + x + 7)

Step 2: Simplify

Answer:

C.-9, -1, -3,5

Step-by-step explanation:

Given

y = 2x - 3 ---- [missing equation]

Required

Complete the table

To do this, we simply substitute the values of x in the given equation.

When x = -3

y = 2 * -3 - 3

y = -6 - 3

y = -9

When x = 1

y = 2 * 1 - 3

y = 2 - 3

y = -1

When x = 0

y = 2 * 0 - 3

y = 0 - 3

y = -3

When x = 4

x = 2 * 4 - 3

y = 8 - 3

y = 5

Hence, the missing gap can be filled with: C.-9, -1, -3,5
