18 divided by 60 = 0.3
0.3 x 100 = 30
18 is 30% of 60
Answer:
The first one is x=-y-2z-7
The second one is x=-1/3y + 1/3z + -4/3
The third one is x= 3y + 2z + 17
Answer:
3/45
Step-by-step explanation:
Answer:
A 18
Step-by-step explanation:
f(x) = 4x + 10
f(2) = 4(2) + 10
f(2) = 8 + 10
f(2) = 18
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
