First, let's divide 810 by 3.
810/3= 270
Then we divide 270 by the number of shelves 5.
270/5= 54
The answer is 54.
Answer:

Step-by-step explanation:
The given trigonometric equation is
for
.
We divide through by 5 to get;
We take the inverse tangent of both sides to obtain;
Since the tangent ratio is positive, it means
could also be in the 3rd quadrant. But this is outside the given range.
Therefore the correct answer is A
The answer is in the attachment
(1/4ab)^-2
Remove negative exponent by rewritten the equation as (4ab)^2
AUse Product rule to get:
4^2a^2b^2
Now raise 4 to the second power to get:
16a^2b^2
The last answer is correct.
Answer:
See below.
Step-by-step explanation:
p^2 + 2
= (6n + 1)^2 + 2
= 36n^2 + 12n + 1 + 2
= 36n^3 + 12n + 3
= 3(12n^2 + 4n + 1).
- which is divisible by 3.
