Whats 12y=9x-30 in standard form

nadya68 [22]

Standard form : Ax + By = C

12y = 9x - 30
-9x + 12y = -30 ....some teachers accept this, with A being negative
but if not, then it is this :
9x - 12y = 30

two bird populations were studied and formulas were developed for each populations growth. the populations p1 and p2 are given b

STatiana [176]

Answer:

$20 e^{k*10} = 60 e^{0.2*10}$

We can divide both sides by 20 and we got:

$e^{10k}= 3 e^{2}$

Now we can appply natural log on both sides and we got:

$10 k = ln(3e^2)$

Now we can divide both sides of the equation by 10 and we got:

$k = \frac{ln(3e^2)}{10}= 0.30986$

So then the aproximate value of k is 0.30986 and rounded would be 0.31

Step-by-step explanation:

We have the following two expression:

$p_1 = 20 e^{kt}$

$p_2 = 60 e^{0.2t}$

We know that the two populations were equal 10 years after the start of the study, so then we can create the following equation:

$20 e^{k*10} = 60 e^{0.2*10}$

We can divide both sides by 20 and we got:

$e^{10k}= 3 e^{2}$

Now we can appply natural log on both sides and we got:

$10 k = ln(3e^2)$

Now we can divide both sides of the equation by 10 and we got:

$k = \frac{ln(3e^2)}{10}= 0.30986$

So then the aproximate value of k is 0.30986 and rounded would be 0.31

Find the missing term! if y=1+i, then y^3-3y^2+(-3y,-3y+1,3y,3i)-1=-i

Kazeer [188]

Y = 1 + i

(1 + i)^3 - 3 * (1 + i)^2 + k - 1 = -i 
(1 + 3i + 3i^2 + i^3) - 3 * (1 + 2i + i^2) + k - 1 = -i 
1 + 3i - 3 - i - 3 - 6i + 3 + k - 1 = -i 
1 - 3 - 3 + 3 - 1 + 3i - i - 6i + k = -i 
-3 - 4i + k = -i 
k = 4i - i + 3 
k = 3i + 3 
k = 3 * (1 + i) 
k = 3y
