Answer:
-2(9x-8)
Step-by-step explanation:
We are to simplify the expression -3.1x+7-7.4x-1.5x-6(x-3/2)
Open the parenthesis
-3.1x+7-7.4x-1.5x-6(x-3/2)
= -3.1x+7-7.4x-1.5x-6x+6(3/2)
= -3.1x+7-7.4x-1.5x-6x+9
Collect like terms
= -3.1x-7.4x-1.5x-6x+7+9
= -12x-6x+16
= -18x+16
= -2(9x-8)
Hence the simplified form of the expression is -2(9x-8)
Hello from MrBillDoesMath!
Answer:
(3 /2)* ( x^(1/2) )
Discussion:
I think you are asking for the derivative of (3x) ^ (1/2) -- the square root of both 3 and x.
The derivative of (3x) ^ (1/2) is
(1/2) (3x) ^ (1/2 -1) (d(3x)/dx) =
(1/2) (3x)^(-1/2) 3 =
3/2 (1/ (3x)^ (1/2) ) =
3/2 ( 1/ 3^(1/2)) ( 1 / x^(1/2) ) =
(3/3^(1/2)) * (1/2) ( 1/ x^(1/2) ) =
( 3^(1/2) / 2 ) * (1/ x^(1/2) ) =
( 3^(1/2) ) * (1 / 2) * (1/ x^(1/2) ) =
It's straightforward but using a keyboard over complicates its appearance
Thank you,
MrB
The answer is -12 because the 4 and 8 are negative
At time t = 0 the pool is empty. At time t = 6 hours the pool is full. Once you have a function that represents the amount of water in the pool, you should be able to put any value for t in the domain 0 <= t <= 6 to find the amount of water in the pool. t can be any real number such as: 1, 1.5, 2.8, 3.6589, etc. So all real numbers from 0 to 6 hours.
Well there is a problem with the question, which is we would need to know the data as well as the units being used in the table
