Answer:

Both A and B

Step-by-step explanation:

For functions you are just trying to make sure all the x's are different.

So let's look at A: The x's there are all different so it is a function

Now let's look at B: The x's there are all different so it is a function.

Both A and B

12 1/2 as a fraction in the simplest form

djverab [1.8K]

12 = 12/1 = 24/2, 24/2+1/2=25/2 so 25/2, and it's in simplest form because 2 can't go into 25

HELP!

Tju [1.3M]

Answer:

(b) 7.28 cis(105.945°)

Step-by-step explanation:

The trig form of a vector is always ...

magnitude(cos(angle)·i +sin(angle)·j)

Sometimes, that is abbreviated ...

magnitude cis(angle) or magnitude∠angle

where the "angle" is measured counterclockwise from the +x axis.

The forms showin in choices C and D can be rejected immediately because the sine and cosine coefficients are incorrectly placed. To differentiate between choices A and B, you need to know whether the angle is greater than 90°. The terminal point is above and left of the initial point, so the angle must be <em>more than 90°</em>. (It can help to plot the points on a graph.)

u = 7.28(cos 105.945°i + sin 105.945°j)
