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}

Pleaseee someone help me :( Ive been stuck on this for an hour

Answer:

The number of times organism B's population is larger than organism A's population after 8 days is 32 times

Step-by-step explanation:

The population of organism A doubles every day, geometrically as follows

a, a·r, a·r²

Where;

r = 2

The population after 5 days, is therefore;

Pₐ₅ = = 32·a

The virus cuts the population in half for three days as follows;

The first of ta·2⁵ he three days = 32/2 = 16·a

The second of the three days = 16/2 = 8·a

After the third day, Pₐ = 8/2 = 8·a

The population growth of organism B is the same as the initial growth of organism A, therefore, the population, P₈ of organism B after 8 days is given as follows;

P₈ =  a·2⁸ = 256·a

Therefore, the number of times organism B's population is larger than organism A's population after 8 days is P₈/Pₐ = 256·a/8·a = 32 times

Which gives, the number of times organism B's population is larger than organism A's population after 8 days is 32 times.

Hope this helps you out! :)

Also, it's OK! This was actually pretty hard to figure out!

Solve the system of equations. \begin{aligned} &amp; -5y-10x = 45 \\\\ &amp;-3y+10x=-5 \end{aligned} ​ −5y−10x=45 −3y+10x=−5 ​
sineoko [7]

Answer:

x = -2

y = -5

Step-by-step explanation:

We can solve this algebraically (substitution or elimination) or graphically. I will be using elimination:

Step 1: Add the 2 equations together

-8y = 40

y = -5

Step 2: Plug <em>y </em>into an original equation to find <em>x</em>

-3(-5) + 10x = -5

15 + 10x = -5

10x = -20

x = -2

And we have our final answers!

Cost of NYC rentals: 525 + 0.21m

Cost of Metro Trucks: 585 + 0.13m

 

<span>b.      </span>525 + 0.21m = 850

0.21m = 325

M = 1,548 miles

<span>c.       </span>Initial cost for NYC rentals = $525

Initial cost for Metro Trucks = $585

<span>d.      </span>NYC rentals: 525 + 0.21 (500) = $630

Metro Trucks rentals: 585 + 0.13 (500) = $650

<span>e.      </span>525 + 0.21m = 585 + 0.13m

0.21m – 0.13m = 585 – 525

0.08m = 60

m = 750 miles
