Answer:
the scale factor is 4 to 1, or just 4.
Step-by-step explanation:
Solution:
we are given that
A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the schoo. The order of selection does not matter.
As we know
6 teacheras can be selected out of 30 teacher in
ways.

Hence the required number of ways is 593775.
the solution is in the above picture.
1. Divide both sides by 2
2. Add 16 to each side
Answer x > -2
Cot x = cos x / sin x
cot π/4 = cot 45° = cos 45° / sin 45°
We know that sin 45° and sin 45° have the same value:
cos 45° = sin 45° = √2 / 2;
cos 45° / sin 45° = √2/2 : √2/2 = 1
Answer:
cot π/4 = 1
