Find the general indefinite integral. (Use C for the constant of integration. Remember to use absolute values where appropriate.

Maru [420]

Answer:

$9\text{ln}|x|+2\sqrt{x}+x+C$

Step-by-step explanation:

We have been an integral $\int \frac{9+\sqrt{x}+x}{x}dx$ . We are asked to find the general solution for the given indefinite integral.

We can rewrite our given integral as:

$\int \frac{9}{x}+\frac{\sqrt{x}}{x}+\frac{x}{x}dx$

$\int \frac{9}{x}+\frac{1}{\sqrt{x}}+1dx$

Now, we will apply the sum rule of integrals as:

$\int \frac{9}{x}dx+\int \frac{1}{\sqrt{x}}dx+\int 1dx$

$9\int \frac{1}{x}dx+\int x^{-\frac{1}{2}}dx+\int 1dx$

Using common integral $\int \frac{1}{x}dx=\text{ln}|x|$ , we will get:

$9\text{ln}|x|+\int x^{-\frac{1}{2}}dx+\int 1dx$

Now, we will use power rule of integrals as:

$9\text{ln}|x|+\frac{x^{-\frac{1}{2}+1}}{-\frac{1}{2}+1}+\int 1dx$

$9\text{ln}|x|+\frac{x^{\frac{1}{2}}}{\frac{1}{2}}+\int 1dx$

$9\text{ln}|x|+2x^{\frac{1}{2}}+\int 1dx$

$9\text{ln}|x|+2\sqrt{x}+\int 1dx$

We know that integral of a constant is equal to constant times x, so integral of 1 would be x.

$9\text{ln}|x|+2\sqrt{x}+x+C$

Therefore, our required integral would be $9\text{ln}|x|+2\sqrt{x}+x+C$ .

ANSWER:

A cross section parallel to the base is a rectangle measuring 15 inches by 6 inches.

A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.

A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 4 inches by 15 inches.

A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.

Answer:

Steve's pay is the highest and is equal to 55 dollars per hour.

The column for pay corresponding to 1 hour is $55.

Step-by-step explanation:

Geeta's pay:

The equation for Geeta's pay is given as:

$p=75+45h$

Where, 'p' is in dollars and 'h' is in hours.

The above equation is a linear equation of the form $y=mx+b$ , where 'm' is the rate of change of pay or the pay per hour.

So, the pay per hour of Geeta is 45 dollars.

Richard's pay:

The graph of Richard's pay is a straight line. The slope of the line gives the rate of change of pay or the pay per hour.

The slope of the line is given as:

Slope = Rise over run = $\frac{80-50}{1-0}=30$ dollars per hour.

So, Richard's pay per hour is 30 dollars.

Steve's pay:

The table of hours and pay is given.

The rate of change or pay per hour can be obtained by using two values of both hours and pay.

Consider $h=3\ and\ h=5$ and $p=165\ and\ p=275$

Now, pay per hour = $\frac{275-165}{5-3}=\frac{110}{2}=55$ dollars

Therefore, Steve's pay per hour is 55 dollars.

The column for pay corresponding to 1 hour is $55.

On comparing, Steve's pay is the highest and is equal to 55 dollars per hour.
