Use complete sentences to explain the relationship between tan 5pi/4 and tan pi/4. In your answer, reference specific values on
Kisachek [45]
Remark
pi/4 is between 0 and pi/2 which means that pi/4 is in the first quadrant.

5*pi / 4 is between pi and 3/2 pi which means that the angle is in the third quadrant. 

So you are talking about one two angles that are in the first and third quadrants.

Step One
Find the Tangent of pi/4 using the unit circle as a reference.

Since pi/4 is 1/2 way between 0 and pi/2 you are referring to something that has and x value of 0.707 for an x value and 0.707 for a y value. (They are equal)

That is the point where the opposite / adjacent = 0.707/0.707 = 1

Step Two
Find the tangent of 5pi/4 using the unit circle.
Using the same argument as pi/4 this time the opposite / adjacent = -0.707/-0.707 = 1 ( the two minus signs cancel out.)

Solve equation X/4-7=-3
Anettt [7]
This could mean two things from how you’ve written it.

It could mean there is an X with the denominator 4 or it could mean there’s an X with the denominator 4-7.

I am going to work with the first one and assume the 7 is separate. Apologies if that is incorrect.

First, I would add the 7 to both sides.

This leaves you with X/4 = 4

Then, multiply both sides by 4, to get X on its own.

This leaves X=16, which is the answer.

Express 275% as a decimal number
Lorico [155]
Hello there! 

Alright so, 100% is equal to 1, because think about it as a fraction, 2/3 is 66%, because it's not full, and 2/3 is 66%, but it's also .66(etc). So, in order to get 100% you'd have to have a 3/3.

I'm going to use 4/4. so in order to go above 100% you'd have to add more.

8/4 is 200% because it divides to 2.00

So now just add 3 more because 3/4 is 75%

11/4 is 275%

Which also divides to 2.75

2.75 is your answer, hope this helped!
