What’s the cot(180°) + (cos(180°)/sin(180°))

Mathematics
1 answer:
KatRina [158]3 years ago
6 0

Answer:

the answer is 'undefined'

Step-by-step explanation:

Cot is defines as (cos x)/(sin x)

So we can rewrite our expression as...

(cos 180°)/(sin 180°) + (cos 180°)/(sin 180°)

or

2(cos 180°)/(sin 180°)

Cos 180° = 1, sin 180° = 0   (you get these from the unit circle)

so we have

2(1/0) = 2/0,  which is undefined, because we don't divide by zero

Johnny is paid a one-time fee of $245.00 for all his jobs. His uncle also pays him $20.00 for each hour that he works. After all
Free_Kalibri [48]

Answer:

100 hours

Step-by-step explanation:

If Johnny is paid 245.00 as a one time fee for all his jobs then the total money he is paid is 2245.00

We need to separate the hourly fee from the one-time fee so we subtract 245 from 2245. This leaves us with 2000 dollars.

We know that he will be paid 20 dollars per hour so we need to divide 2000 by 20. This leaves us with 100.

<h2>Therefore Johnny worked 100 hours</h2>
