5 is the correct answer. First you had to factor by the numbers, and it gave us, $25=5^2=5*5=25$ , or $=5^2$ . Then you apply radical rule, and it gave us, $\sqrt{5^2}=5$ , and it gave us the answer is 5 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Problem PageQuestion It takes an older pump twice as long to drain a certain pool as it does a newer pump. Working together, it

Answer:

It will take 6 hours for the new pump to drain the pool.

Step-by-step explanation:

As the complete question is not given, the complete question is found online and is attached herewith

Let the rate of new pump is given as x=W/t_1

Let the rate of the old pump is given as y=W/t_2

it is given that the time t_2=2t_1

So by substituting the values of t_2 in the rate equation of y

y=W/2t_1

y=(W/t_1*2)=x/2

Also the total rate of both the pumps is given as W/t3 where t3 is given as 4 hours so the equation becomes

x+y=W/4

x+x/2=W/4

3x/2=W/4

As x=W/t_1

3W/2t_1=W/4

Now as W is same on both sides so

3/2t_1=1/4

12=2t_1

t_1=6 hours

So it will take 6 hours for the new pump to drain the pool.

Determine whether the statement is true or false, and explain why.

Sedbober [7]

Answer:

True

Step-by-step explanation:

The integral

$\int\limits^1_0 {xe^{10x}} \, dx$

in the integral we have a product of a monomial: $x$

and an exponential function: $e^{10x}$

In general case, when we have a combination of these two things you can use the integration by parts, where $x$ will be $u$ and $e^{10x}$ will be $dv$ .
