Your domain is all positive numbers, and your range is all numbers. this is because no matter what you plug in for y, x will only ever get extremely close to 0, but never reach it or go below it, and if you put in large values of y x will get very big.

Show that det(A) = 0 without directly evaluating the determinant. A = [-4 1 1 1 1; 1 -4 1 1 1; 1 1 -4 1 1; 1 1 1 -4 1; 1 1 1 1 -

You could interpret them as system of equation and answer the question easily

from A 

-4x + y + x + w =1

write in same form from A 

as this system has five variables and four of them are unknowns it means the unique solution is not possible 

So, det (A) = 0

Next-door neighbors Bob and Jim use hoses from both houses to fill Bob's swimming pool. They know that it takes 12 h using both
Leokris [45]

Answer:

Jim's hose: 27 hours.

Bob's hose: 21.6 hours.

Step-by-step explanation:

Let t represent hours taken by Jim's hose.

Part of pool filled by Jim's hose in 1 hour would be \frac{1}{t}.

We have been given that Bob's hose, used alone, takes 20% less time than Jim's hose alone. This means that Bob's hose take will take 80% time of Jim's hose that is 0.8t.

Part of pool filled by Bob's hose in 1 hour would be \frac{1}{0.8t}.

We are also told that it takes 12 hours using both hoses. Part of pool filled by both hoses in 1 hour would be \frac{1}{12}.

Now, we will add rates of both hoses and equate with \frac{1}{12} as:

\frac{1}{t}+\frac{1}{0.8t}=\frac{1}{12}

\frac{0.8}{0.8t}+\frac{1}{0.8t}=\frac{1}{12}

\frac{0.8+1}{0.8t}=\frac{1}{12}

\frac{1.8}{0.8t}=\frac{1}{12}

Cross multiply:

0.8t*1=1.8(12)

0.8t=21.6

\frac{0.8t}{0.8}=\frac{21.6}{0.8}

t=27

Therefore, it will take 27 hours for Jim's hose to fill the pool alone.

Time take by Jim's hose alone: 0.8t\Rightarrow 0.8(27)=21.6.

Therefore, it will take 21.6 hours for Bob's hose to fill the pool alone.
