Answer:

Step-by-step explanation:

$\displaystyle\ \lim_{n \to a} \dfrac{\sqrt{2x}-\sqrt{3x-a} }{\sqrt{x}-\sqrt{a}} =\frac{0}{0} \\\\we\ can \ use\ Hospital's\ Rule\\\\\\f(x)=\sqrt{2x}-\sqrt{3x-a} \qquad f'(x)=\dfrac{2}{2*\sqrt{2x}} -\dfrac{3}{2*\sqrt{3x-a}} \\\\g(x)=\sqrt{x} -\sqrt{a} \qquad g'(x)=\dfrac{1}{2\sqrt{x}} \\\\\\\displaystyle\ \lim_{n \to a} \dfrac{\sqrt{2x}-\sqrt{3x-a} }{\sqrt{x}-\sqrt{a}} =\lim_{n \to a} \dfrac{\dfrac{2}{2*\sqrt{2x}} -\dfrac{3}{2*\sqrt{3x-a}} }{\dfrac{1}{2\sqrt{x}} }\\\\$

$\displaystyle \lim_{n \to a} \dfrac{2\sqrt{x} }{\sqrt{2x}} -\dfrac{3*\sqrt{x} }{\sqrt{3x-a}} =\lim_{n \to a} \dfrac{2 }{\sqrt{2}} -\dfrac{3*\sqrt{x} }{\sqrt{3x-a}}\\\\\\=\dfrac{2}{\sqrt{2}} -\dfrac{3*\sqrt{a} }{\sqrt{2a}}\\\\\\=\dfrac{2}{\sqrt{2}} -\dfrac{3}{\sqrt{2}}\\\\\\=-\ \dfrac{1}{\sqrt{2}}\\\\$

Simplify each expression by combining like terms <br> 3x^-1 - 10x^-1

Dmitry_Shevchenko [17]

Answer:

-7/x

Step-by-step explanation:

first, you combine the terms together to get -7x^-1. you cant have negative exponents in the numerator so you move the x^-1 to the denominator. once it move its becomes positive then.

Using exponents don't understand what's 9 cubed and 20 squared how do I do it in expanded form whett

Naily [24]

Expanded form is when you just write it out.

so 9 cubed becomes:

9×9×9

and 20 squared becomes:

20×20

the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.

Select the correct answer.

viva [34]

Answer:

As the given equation represents a quadratic function.

Thus, $y\:=\:x^2-9x$ represents a function.

As we know that the function is just a relation in which each input has only one output.

Thus, $y\:=\:x^2-9x$ represents a relation and function.

Step-by-step explanation:

Given the equation

$y\:=\:x^2-9x$

As the given equation represents a quadratic function.

Thus, $y\:=\:x^2-9x$ represents a function.

As we know that the function is just a relation in which each input has only one output.

Thus, $y\:=\:x^2-9x$ represents a relation and function.

We know that the domain of a function is the set of input or argument values for which the function is real and defined.

$\mathrm{Domain\:of\:}\:x^2-9x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

We also know that the range of a function is the set of values of the dependent variable for which a function is defined.

$\mathrm{Range\:of\:}x^2-9x:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:-\frac{81}{4}\:\\ \:\mathrm{Interval\:Notation:}&\:[-\frac{81}{4},\:\infty \:)\end{bmatrix}$

The graph is also attached below. From the graph, it is clear that it represents a Parabola.

The sum of five consecutive numbers is 360. What is the smallest of these numbers? *

guajiro [1.7K]

Answer:

Step-by-step explanation:

An easy way to do this is to simply take 360(the sum) and divide it by 5(the number of numbers) to get 72. Thus, 72 is the middle number and the numbers are:

72,72,73

70,71,72,73,74

The smallest of these numbers is 70
