Decompose -6x/(x+4)(x-4) into partial fractions

Answers

Answer 1
Answer: Hello,

Integration fractions?

-6x/((x+4)(x-4))=A/(x+4)+B/(x-4)=((A+B)x-4A+4B)/((x+4)(x-4))
==> A+B=-6 and -4A+4B=0
==>A=B=-3

Answer -3/(x+4)-3/(x-4)

Simplify. Write in radical form.
(x^3y^-2/xy)^-1/5

Answers

Answer:

The radical form of the expression ((x^3y^(-2))/(xy))^{(-1)/(5)} is \sqrt[5]{(y^3)/(x^2)}

Step-by-step explanation:

 Given : ((x^3y^(-2))/(xy))^{(-1)/(5)}

We have to simplify the given expression and write in radical form.

RADICAL FORM is the simplest form of expression that do not involve any negative exponent and power is less than n, where n is the nth root of that expression.

Consider the given expression  ((x^3y^(-2))/(xy))^{(-1)/(5)}

Cancel out the common factor x, we get,

((x^2y^(-2))/(y))^{(-1)/(5)}

Using laws of exponents, a^(-m)=(1)/(a^m) , we have,

((x^2)/(y\cdot y^2))^{(-1)/(5)}

Using laws of exponents, x^m \cdot x^n=x^(m+n) , we have,

((x^2)/(y^3))^{(-1)/(5)}

Again using laws of exponents, a^(-m)=(1)/(a^m) , we have,

((y^3)/(x^2))^{(1)/(5)}

Also, written as  \sqrt[5]{(y^3)/(x^2)}

Thus, the radical form of the expression ((x^3y^(-2))/(xy))^{(-1)/(5)} is \sqrt[5]{(y^3)/(x^2)}

A 10 meter long wire is attached to the top of a flagpole 5√3 meters long. What is the measure of the angle the wire makes with the ground?A. 25 degrees
B. 45 degrees
C. 60 degrees
D. 90 degrees

Answers

Well there has to be a right angle in there somewhere as the pole must be perpendicular to the ground.

Using the sine rule:
sinA/a = sinB/b where a = 10, A = 90, b = 5√3, B = B
Re-arrange for B, B = arcsin (b(sinA)/a)
B = arcsin(5√3(sin90)/10)
B = 60 degrees.

Answer is C

Is 4xy + 2y = 9 linear ? If yes write the equation in standard form & determine the x & y interests

Answers

no it is not. if that y by the x wasn't there then yes it would be

Final answer:

Yes, the equation 4xy + 2y = 9 is linear. Its standard form is 4xy + 2y - 9 = 0. The x-intercept is (2.25, 0) and the y-intercept is (0, 4).

Explanation:

Yes, the equation 4xy + 2y = 9 is linear. To write it in standard form, we can rearrange the terms to bring them all to one side of the equation:



4xy + 2y - 9 = 0



The x and y intercepts can be determined by setting either x or y to 0 and solving for the other variable. Let's set x = 0:



2y - 9 = 0



Solving for y, we get y = 4. So the y-intercept is (0, 4).



Next, let's set y = 0:



4x + 0 - 9 = 0



Solving for x, we get x = 2.25. So the x-intercept is (2.25, 0).

What is the difference in simplest form? (n^2+10n+21/n^2+3n-28)-(3n/n-4)

Answers

Answer:

(3-2n)/(n-4)

Step-by-step explanation:

We have been given the expression

(n^2+10n+21)/(n^2+3n-28)-(3n)/(n-4)

Let us write the numerator and denominator of first expression in factored form using AC method.

n^2+10n+21\n=n^2+7n+3n+21\nn(n+7)+3(n+7)\n(n+7)(n+3)

And the factors of denominator is

n^2+3n-28\n=n^2+7n-4n-28\nn(n+7)-4(n+7)\n(n+7)(n-4)

Therefore, the expression becomes

((n+7)(n+3))/((n+7)(n-4))-(3n)/(n-4)\n\n\text{Cancel the common terms}\n\n(n+3)/(n-4)-(3n)/(n-4)\n\n\text{Denominator of both rational expression is same}\n\text{hence, we can directly add the numerators}\n\n(n+3-3n)/(n-4)\n\n(3-2n)/(n-4)

Thus, the simplified form is (3-2n)/(n-4)

The answer is (-2n+3)/(n-4)
