So you have to find how many seconds it takes to fill up with 1 inch.
TO find that, you have to divide 45/3 which equals to 15.
So it takes 15 seconds for 1 inch. The question is asking you to find out how many seconds will it take to fill the tub with 20 inches.
SO your gonna multiply 15*20.
15*20 = 300
So it would take 300 seconds to fill up Camden's tub.
Answer:
4k - 8
Step-by-step explanation:
Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.
Hope this helps!
The period of y = 4 cos(8πx) is 2π/(8π) = 1/4, since
cos(x - 2π) = cos(x)
and if we replace x with 8πx, we get
cos(8πx - 2π) = cos(8πx)
and
8πx - 2π = 8π (x - 1/4)
