The slope f′(x) at each point (x,y) on a curve y=f(x) is given, along with a point (a,b) on the curve. Use this information to f

Montano1993 [528]

$f'(x)=\dfrac{4x}{1+7x^2}$

Integrating gives

$f(x)=\displaystyle\int\frac{4x}{1+7x^2}\,\mathrm dx$

To compute the integral, substitute $u=1+7x^2$ , so that $\frac27\,\mathrm du=4x\,\mathrm dx$ . Then

$f(x)=\displaystyle\frac27\int\frac{\mathrm du}u=\frac27\ln|u|+C$

Since $u=1+7x^2>0$ for all $x$ , we can drop the absolute value, so we end up with

$f(x)=\dfrac27\ln(1+7x^2)+C$

Given that $f(0)=10$ , we have

$10=\dfrac27\ln1+C\implies C=10$

so that

$\boxed{f(x)=\dfrac27\ln(1+7x^2)+10}$

Seven men and seven women line up at a checkout counter in a store. In how many ways can they line up if the first person in lin

luda_lava [24]

Answer: The required number of ways is 25401600.

Step-by-step explanation: Given that seven men and seven women line up at a checkout counter in a store.

We are to find the number of ways in which they can line up, if the first person in line is a man , and the people in line alternate man, woman, man, woman and so on.

Since the first person is a man, so

for first position, we have 7 options.

There are alternate man and women in the line, so the second person must be a women.

That is, we have 7 options for the second position.

Similarly, for 3rd and 4th positions, we have 6 options for each, and so on.

Therefore, the number of ways in which the 14 persons can line up is

$n=7\times7\times6\times6\times5\times5\times4\times4\times3\times3\times2\times2\times1\times1=7!\times7!=5040\times5040=25401600.$

Thus, the required number of ways is 25401600.
