Answer:

10.083333...ft

Step-by-step explanation:

length = 12ft

area = 121sqft

area = length * width

121sqft = 12ft * width

width = 121sqft / 12ft

[tex]width = 10\frac{1}{12}\mathrm{ft}[/tex]

width = 10.08(3)ft

We need to know about natural exponential function to solve the problem. The given function is a natural base exponential function.

An exponential function is a function in which x is an exponent. An exponential function has an exponential graph that keeps growing. A natural base exponential function is one where the base of the function is e which is a mathematical constant and is approximately equal to 2.71828. The inverse of a natural exponential function is a logarithmic function. An exponential function is of the form y=[tex]b^{x}[/tex] where b is the base, in a natural base exponential function, the b is replaced by e which means y=[tex]e^{x}[/tex]. In the given question y=[tex]e^{x+7}[/tex] is a natural base exponential function since the base is the natural base.

Therefore we found that the given function is a natural base exponential function.

The rational number between the square root of 7 and the square root of 8 is 27/10

Rational expressions are expressions that are represented by the quotient of two polynomials or radicals.

This means that, a rational expression is represented by a fraction whose numerator and denominator are polynomials or radicals

The features of the rational number are given as

Value = between the square root of 7 and the square root of 8

Rewrite the value properly

So, we have

Value = between √7 and √8

Evaluate the values of √7 and √8

So, we have

√7 = 2.65

√8 = 2.83

This means that the rational number is between 2.65 and 2.83

A number between 2.65 and 2.83 is 2.7

Express as fraction

value = 27/10

Hence, the rational number between the square root of 7 and the square root of 8 is 27/10

Answer:

B

Step-by-step explanation:

6x - 8x - 4 = - 2x - 2 , that is

- 2x - 4 = - 2x - 2 ( add 4 to both sides )

- 2x = - 2x + 2 ( add 2x to both sides )

0 = 2 ← not possible

this indicates the equation has no solution

Answer:

6x-8x-4=-2x-2 (group the like terms)

6x-8x+2x= 4-2 (-8x+2x= -6x and 6x-6x=0) (4-2=2)

answer= 0=2

,therefore: it has no solution

Step-by-step explanation:

the answer is 0=2 which mean there is nothing that 2 is equivalent to because when you group the like terms and work out the answer the x in the equation will be canceled.

The cost of the Ginnie's dinner is a $40 and the cost of his cousin's dinner is $25.

According to the statement

We have to find that the cost of their dinners.

So, For this purpose, we all know that the

The cost function may be wont to find the common cost, which is that the average amount of cash it costs to provide a unit.

From the given information:

Ginnie dinner cost $15 over her cousin's. If their combined bill was under $65.

Then

Let Ginnie dinner is x and his cousin's be y.

Then

x+y = 65 And x = y+15

Then

Substitute the values then y+15+y = 652

y+15 = 652

y = 65-152

y = 50

[tex]y = \frac{50}{2}[/tex]

y = 25.

Then x = y+15

x = 25+15

x = 40.

So, The cost of the Ginnie's dinner is a $40 and the cost of his cousin's dinner is $25.

Answer:

No Solution

Step-by-step explanation:

An absolute value will always have a positive value. If you isolate the absolute value it shows the abs val LESS THAN a negative number. Its not possible to have a positive less than a negative.

If you just go on and do the problem in auto-pilot, the answers don't check. ALSO since it it a LESS THAN inequality statement BOTH of the inequalities have to be true at the same time which is not possible.

The divide and simplify of the equation √36 x⁴ / √9 x⁶ will result to  [tex]\frac{2}{x^{2} }[/tex]

Let's begin by simplifying the equation;

Simplify the equation by finding the square root of both 36 and 9

The square root of 36= 6

The square root of 9= 3

= [tex]\frac{6x^{4} }{3x^{6} }[/tex]

The above equation can also be written as;

=  [tex]6x^{4} * 3x^{-6}[/tex]

The next step is to solve the powers, that is,

=   [tex]\frac{6x^{4} }{3x^{6} }[/tex]

Cancel out 6 by 3 and get  2

The result is,  

=  [tex]\frac{2}{x^{6-4} }[/tex]

The final submission result is,

=  [tex]\frac{2}{x^{2} }[/tex]

No extraneous solution to the equation.

The equation is:

3[tex]\sqrt{2x}[/tex] - 3= 9

To know whether the equation has an extraneous solution, first we need to find the value of x.

[tex]3\sqrt{2x}[/tex] = 12

[tex]\sqrt{2x}[/tex] = 4

2x = 16

x = 8

Now put the value of x in the equation.

3[tex]\sqrt{2 * 8}[/tex] - 3 = 9

3× 4 - 3 = 9

12 - 3= 9

9 = 9

Therefore there is no extraneous solution to the equation, x = 8 is the solution of the equation.

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

-7 = extraneous solution

The equation is

[tex]\sqrt{-3x - 5}[/tex] = x + 3

To find the value of x we need to square both sides of the equation

[tex](\sqrt{-3x - 5})^{2}[/tex] = [tex](x + 3)^{2}[/tex]

- 3x -5 = [tex]x^{2}[/tex] + 6x + 9

[tex]x^{2}[/tex] + 9x + 14 = 0

[tex]x^{2}[/tex] + 7x + 2x + 14 =0

x( x + 7) + 2( x + 7) = 0

(x + 7) (x + 2 ) = 0

x = -2, -7

To find the extraneous solution we have to put both the value of x in the equation.

x=-2

[tex]\sqrt{(-3 * -2) - 5}[/tex] = -2 +3

[tex]\sqrt{1}[/tex] = 1

1 = 1

x = -7

[tex]\sqrt{(-3 * -7) - 5}[/tex] = -7 +3
