Step-by-step explanation:

1 Find common denominator (lower numbers)

2 add numerators(top numbers)

3 put the numerator over the denominator

ex 3/4+2/8

3x2=6,4x2=8

3/4=6/8

6/8+2/8=8/8 or 1

Suppose two fractions be

Now

$\\ \rm\Rightarrow \dfrac{a}{b}+\dfrac{c}{d}$

Find LCM of b and d
divide LCM by b and d and multiply with a and c respectively

$\\ \rm\Rightarrow \dfrac{ad+bc}{bd}$

Which of the following rational functions is graphed below?

IrinaVladis [17]

Answer:

Option (D)

Step-by-step explanation:

The given graph represents a rational function having,

1). Vertical asymptote → x = 2

2). Horizontal asymptote → y = 0

Parent function representing the rational function will be in the form of,

F(x) = $\frac{1}{x^{2} }$

Since, vertical asymptote of the function is x = 2, denominator of the function will be in the form of (x - 2)².

Since, horizontal asymptote of the function is y = 0, highest exponent term in the numerator will be 0.

Therefore, numerator of the fraction will be x⁰.

The rational function given in the graph will be,

F(x) = $\frac{x^{0}}{(x-2)^2}$

F(x) = $\frac{1}{(x-2)^2}$

Option (D) will be the answer.

How would you round the number 9.9813 x 10-5 to two significant figures? Group of answer choices 10 1.0 x 10-4 10.0 x 10-5 9.9 x

zaharov [31]

Answer:

This Significant Figures Rounding Calculator rounds a given number to the amount of significant digits that you specify. This rounding number which you specify cannot be a negative number and it must be greater than 0. A number with 0 significant digits would be 0.

Find a formula for the described function. Express the surface area of a cube as a function of its volume v.

Digiron [165]

Let the side of the cube=a

So the volume will be=V=a³

Then surface area of the cube will be=6a²= $\frac{6a^3}{a}$ = $\frac{6V}{a}$

The above expression showing surface area as a function of Volume. (Answer)

Let T denote the time in minutes for a customer service representative to respond to 10 telephone inquiries. T is uniformly dist

ivanzaharov [21]

Answer:

The answer is " $f_{R} (r) =\frac{5}{2r^2}; \frac{10}{12} \leq r \leq \frac{10}{8}$ "

Step-by-step explanation:

They have the distributional likelihood function of T: $f_{\Gamma } \ (t)= \frac{1}{12-8}= \frac{1}{4}; 8 \leq t \leq 12$

This is the following PDF of transformation $R =\frac{10}{T}$

They know that PDF is the Y=g(X) transformation

$f_{y} (y)=f_{x} (g^{-1} (y))|\frac{dg^{-1} (y)}{dy}$

Using theformula, the PDF of $R =\frac{10}{T}$ is

$f_{R} (\Gamma)=f_{(\Gamma)} |\frac{d(\frac{10}{r})}{dr}| \\\\f_{R}(r) =\frac{1}{4}| -\frac{20}{r^2}|\\\\f_{R} (r) =\frac{5}{2r^2}; \frac{10}{12} \leq r \leq \frac{10}{8}\\\\$
