Answer:

xe^{x} - e^{x} +C

Step-by-step explanation:

we will solve this using integration by parts as the problem is a product of two functions which none of them are constants.

∫udv = uv -∫vdu   ..............equ 1

∫xe^{x}

u=x ,

du= 1  

dv =e^{x}

v=∫dv= e^{x}

Substituting into  equ 1

∫udv = xe^{x} - ∫e^{x}dx

<em>∫udv = xe^{x}- e^{x} + C</em>

Amber got a raise, and her hourly wage increased from $8 to $9.50 what is the percent increase
I am Lyosha [343]

Answer:

The percent increase is <u>18.75%</u>.

Step-by-step explanation:

Given:

Amber got a raise, and her hourly wage increased from $8 to $9.50.

Now, to find percent increase.

Previous wage = $8.

Wage raised = $9.50.

So, to get the increased wage we subtract the previous wage from the wage raised:

\$9.50-\$8=\$1.50.

Now, to get the percent increase:

\frac{1.50}{8} \times 100

=\frac{150}{8}

=18.75\%.

Therefore, the percent increase is 18.75%.
