Answer:
He purchased 125 nails.
Step-by-step explanation:
if each nail cost $0.12 you would take $15 and divide it by $0.12.
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
Answer:
No, not a function
Step-by-step explanation:
Functions cannot have two or more same domain and different range. (3,3) and (3,9) have same domain and different range.
$480 is the price after the discount was added. We can then assume that $480 is 3/4 the price of the original item. To find 1/4, we simply divide by 3, which equals $160. since $160 is one quarter of the price, the original price was $640.
