Write the form of the partial fraction decomposition of the function. Do not determine the numerical values of the coefficients.
Gnoma [55]

Answer:

\frac{A}{(x-1)} + \frac{B}{(x-9)}

Step-by-step explanation:

Given the expression \dfrac{1}{(x-1)(x-9)}, we are to write the expression as a partial fraction. Writing as a partial fraction means rewriting the expression a s a sum of two or more expression.

Before we will do this we will need to check the nature of the function at the denominator whether it is linear, quadratic or a repeated function. According to the question, the denominator at the denominator is a linear function and since it is a linear function, we can separate both linear function without restriction as shown;

\dfrac{1}{(x-1)(x-9)} = \frac{A}{(x-1)} + \frac{B}{(x-9)} where A and B are the unknown constant which are numerical values.

Convert theta= 3pi/4 to rectangular form.
Usimov [2.4K]

\theta=\dfrac{3\pi}{4}=\pi-\dfrac{\pi}{4}\\\\y=\tan\theta x\\\\y=\left(\tan\dfrac{3\pi}{4}\right)x\\\\y=\left(\tan\left(\pi-\dfrac{\pi}{4}\right)\right)x\\\\y=\left(\tan\left(-\dfrac{\pi}{4}\right)\right)x\\\\y=\left(-\tan\dfrac{\pi}{4}\right)x\\\\y=-1x\\\\\boxed{y=-x}\to\boxed{D.}

I don’t know how to solve this
Colt1911 [192]

Answer:

x=0, -3/4

Step-by-step explanation:

We can solve by factoring. We will factor by GCF the greatest common factor. 8x^2 and 6x share several factors in common:

  • they both share an x
  • they both share 2

I pull out 2x and I get 2x(4x+3)=0. I now set each factor equal to 0 and solve for x.

2x=0

x=0


4x+3=0

4x=-3

x=-3/4
