You can integrate it by substitution:

\large\begin{array}{l} \mathsf{\displaystyle\int\!e^{2x}\,dx}\\\\ =\mathsf{\displaystyle\int\!\frac{1}{2}\cdot 2e^{2x}\,dx}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!e^{2x}\cdot 2\,dx\qquad(i)} \end{array}


\large\begin{array}{l} \textsf{Now substitute}\\\\ \mathsf{2x=u\quad\Rightarrow\quad 2\,dx=du}\\\\\\ \textsf{then (i) becomes}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!e^u\,du}\\\\ =\mathsf{\dfrac{1}{2}\cdot e^u+C}\\\\ =\mathsf{\dfrac{1}{2}\cdot e^{2x}+C} \end{array}


\large\begin{array}{l} \boxed{\begin{array}{l} \mathsf{\displaystyle\int\!e^{2x}\,dx=\frac{1}{2}\cdot e^{2x}+C} \end{array}}\qquad\checkmark \end{array}

Find the measure of
koban [17]

Answer:

m∡GHI = 21°

Step-by-step explanation:

Since the lines are intersecting, GHI and JHK are opposite angles, so they are the same measure.

That means you can set them equal to each other

x + 7 = 3x - 21

x = 14

Now plug x into GHI

14 + 7 = 21

m∡GHI = 21°

If the Laffite family deposits $8500 in savings account at 6.75% interest, compounded continuously, how much will be in the acco
vitfil [10]

Answer:

Option b

Step-by-step explanation:

We have a compound interest problem. With an annual interest rate of 0.675 and an initial payment of 8500, with t = 25 years

Then you must use the annual compound interest formula, which is represented by a growing exponential function:

y = e ^{ht}

Where:

h is the interest rate of 0.675

y is the money in the savings account as a function of time

Then substitute the values in the formula and we have:

y = e ^{0.675(25)}

y = 45,950.57
