Use a change of variables to find the indefinite integral xe^(x^2) dx
ValentinkaMS [17]
\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12\int2xe^{x^2}\,\mathrm dx

If we take y=x^2, then \mathrm dy=2x\,\mathrm dx, and we can write the above integral as


\displaystyle\frac12\int e^y\,\mathrm dy=\frac12e^y+C

and undoing the substitution, we end up with

\displaystyle\int xe^{x^2}\,\mathrm dx=\frac12e^{x^2}+C

Level 3<br> Solve: |x + 2|– 5 = -1
leonid [27]

Answer:

x=−6

x=2

Step-by-step explanation:

Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side. Remember to follow the order of operations.

∣x+2∣−5=−1

Add 5 to both sides of the equation.

∣x+2∣=4

Use the definition of absolute value.

x+2=4

x+2=−4

Subtract 2 from both sides of the equation.

x=2

x=−6

Mike earns $15 for each hour he work plus a $25 bonus. How much does he earn in 10 hours of work?
MakcuM [25]
<h3>Hello there!</h3>

We are trying to find how much Mike earns when he worked for 10 hours

Lets make an equation out of the given information in the question.

We know that:

  • Earns $15 each hour
  • $25 bonus

We would format it as y = mx + b

Our equations would be y = 15x + 25

"x" being the amount of hours he worked

We know that he worked 10 hours, so we would plug 10 into x.

Then, we can solve.

y = 15(10) + 25

y = 150 + 25

y = 175

<h3>Answer: $175</h3><h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>
