Answer:

Constant of proportionality = 1/3

y = 1/3a

Step-by-step explanation:

Constant of proportionality: k = y/x

k = 1/3

k = 4/12 = 1/3

Step-by-step Explanation:

We are going to solve this problem using integration by parts. We can write the integrand as

[tex]\dfrac{4x}{x^2+4x+3} = \dfrac{4x}{(x+3)(x+1)}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{A}{x+3} + \dfrac{B}{x+1}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{Ax + A + Bx + 3B}{x^2+4x+3}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:=\dfrac{(A+B)x + (A+3B)}{x^2+4x+3}[/tex]

Comparing the above term to the left hand side, we can see that

(A + B)x = 4x

A + 3B = 0

Solving for A and B, we find that A = 6 and B = -2 so our integrand becomes

[tex]\dfrac{4x}{x^2+4x+3} = \dfrac{6}{x+3} - \dfrac{2}{x+1}[/tex]

We can now easily integrate this expression as follows:

[tex]\displaystyle \int{\dfrac{4x}{x^2+4x+3}}dx = 6\int{\dfrac{dx}{x+3}} - 2\int{\dfrac{dx}{x+1}}[/tex]

[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= 6\ln|x+3| - 2\ln|x+1| + C[/tex]

Answer:D

Step-by-step explanation:

Step-by-step explanation:

(x + 20)º and (4x - 5)º are supplementary angles, meaning the sum of their angles = 180º.

(x + 20) + (4x - 5) = 180

5x + 20 - 5 = 180

5x + 15 = 180

5x = 165

165/5 = 33

Answer: x = 33

Answer:

-4( 3x - 0.6y + 12)

Step-by-step explanation:

The expression - 12x + 2.4y - 48 taken a common factor of - 4 we have

- 4(3x - 2y + 12).

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

The common factor on the other hand is the highest possible value that we can divide each of the given terms.

Given, - 12x + 2.4y - 48.

- 12x + 8y - 48.

Taking - 4 as the common factor we'll have

- 4(3x - 2y + 12).

Answer:

x = 6 degrees

Step-by-step explanation:

A straight line is 180 degrees and we can make out three angles the form it, this means the three of them add to 180 using the straight angle theorem:

5x + x + 54 + 90 = 180

6x + 144 = 180

6x = 36

x = 6

If k and l are parralel, that means if you move them to each other, or shift k, you will get the same angle as ABC. Thus, it's still going to be 19 degrees.

Step-by-step explanation:

Well 12 cenitmters divided by 4 minutes equals the amount of centimeters the snail travels per minute, which is 3 centimeters (12 / 4 = 3). but be careful cuz we need to convert the 3 cm to mm. 1 cm = 10 mm so 3 cm = 30 mm.

the snail travels 30 mm per minute
