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:
45:48
Step-by-step explanation:
Convert the 4ft to inches
45in:48in
Answer:
answer is option c
Step-by-step explanation:
Amount = $9,000
interest rate (r) = 12%
interest = $762.00
time = ?
we know,
t = 0.7056 years
t = 0.7056 × 365 days
t = 257.54 days ≅ 258 days
correct answer is option c.
<span>let x be the first integer, then
:
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) = 519
:
6x + 15 = 519
:
6x = 504
:
x = 84</span>
