The equation of the required line parallel to the given line is y = -x - 10.

Slope can be defined as the rate of change.

According to the given question we have to write an equation of a line parallel to the line y = - x - 1 that goes through the point (-2,-8).

We know that lines are parallel because of the same slope they have.

So, the required line also have a slope(m) = -1.

∴ The equation of the required line in slope intercept form can be written as y = mx + b.

Putting the value of given points (-2, -8) in (x,y) t evaluate y intercept b.

So, - 8 = (-1)(-2) + b.

- 8 = 2 + b.

b = -10.

∴The equation of the required line in slope intercept form is  y = -x -10.

Answer:

10 2/5 inches

Step-by-step explanation:

Since P=2L+2W, we can flip it to find the length. For example, we could minus 2L from both sides to get P-2L=2W.

We already know that W is 4.5, and P is 29.4.

Plugging that in, we get 29.4-2L=9. Again we can flip the perimeter, and -29.4 on both sides. This would make -2L=-20.4.

For our last flip, we divide the -2 from both sides to finally get L=10.2 (or 10 1/5 if you want) inches.

The value of logarithm as the quotient of two common logarithms is [tex]\frac{Log 140}{Log5}[/tex]. Because [tex]Log_{a}(b)=Log\frac{b}{a}[/tex]

The logarithm is exponentiation's opposite function in mathematics. This means that the exponent to which a fixed number, base b, must be raised in order to produce a given number x, is represented by the logarithm of that number.

Based on the logarithm base, the logarithmic functions are broadly divided into two types. There are common and natural logarithms. Common logarithms are based on the number 10, while natural logarithms are based on the base "e." The power to which a number must be raised in order to obtain another number is known as a logarithm (see Section 3 of this Math Review for more about exponents).

Using the properties of logarithm the value of the expression is   [tex]\frac{1}{2}log_{5} 15 - log_{5} \sqrt{75} = -\frac{1}{2}[/tex]

According to the question the expression that we have been given is

         =  [tex]\frac{1}{2}log_{5} 15 - log_{5} \sqrt{75}[/tex]

Now solving it step by step using the properties of logarithm which are

      [tex]log a^{m} = m*loga[/tex] ,  [tex]log \frac{x}{y} = logx - logy[/tex]  and [tex]log_{a} a = 1[/tex]

As √75 is also equal to [tex](75)^{1/2}[/tex]. Thus equating in the equation we get

Therefore ,  

           [tex]= \frac{1}{2}log_{5} 15 - log_{5} 75^{\frac{1}{2} } \\= \frac{1}{2}log_{5} 15 - \frac{1}{2} log_{5}{75} \\[/tex]  

As we can see that 1/2 is common in both the terms we will take out 1/2 common from both terms, by which we get

           [tex]= \frac{1}{2} [log_{5} 15 - log_{5}{75} ] \\= \frac{1}{2} [log_{5} \frac{15}{75} ] \\\= \frac{1}{2} [log_{5} \frac{1}{5} ] \\= \frac{1}{2} [log_{5} 1 - log_{5}{5} ]\\= \frac{1}{2} [0 - 1]\\= -\frac{1}{2}[/tex]

Hence using the properties of logarithm the value of the expression is  [tex]\frac{1}{2}log_{5} 15 - log_{5} \sqrt{75} = -\frac{1}{2}[/tex]

A) The roots of the graph f(x) are;  x = -2 and x = -1

B) The value of the function at f(0) is; 2

a) We want to find f(0) of the graph.

Now, f(0) simply refers to the y-values when x = 0.

This is the point at which the graph crosses the y-axis

From the graph we can see that the value here is 2. Thus;

f(0) = 2

b) To find the roots of f(x) , we simply find the points at which the plot crosses the x-axis.

From the graph, the roots are at x = -2 and x = -1

Thus, the roots of the equation are x = -2 and x = -1

-4 is an extraneous solution.

The equation is

[tex](x - 2)^{1/2}[/tex] - [tex](28-2x^{1/4}[/tex] = 0

To know whether the given equation has an extraneous solution or not we need to find the value of x.

[tex](x-2^{1/2}[/tex]= [tex](28-2x)^{1/4}[/tex]

Multiply both sides with the power of 4, and we get

[tex](x- 2)^{2}[/tex] = 28-2x

[tex]x^{2}[/tex] - 4x + 4 = 28-2x

[tex]x^{2}[/tex] - 2x - 24= 0

[tex]x^{2}[/tex]- 6x + 4x -24=0

x(x-6) +4(x-6)=0

(x-6)(x+4) = 0

x = 6 , -4

Now put both the value of x in the equation

x=6

[tex](6-2)^{1/2}[/tex]-[tex](28- 2* 6)^{1/4}[/tex]= 0

[tex]4^{1/2}[/tex]- [tex]16^{1/4}[/tex]= 0

2-2=0

0=0

Now

x = -4

[tex](-4-2)^{1/2}[/tex]-[tex](28-2*-4)^{1/4}[/tex]=0

[tex](-6)^{1/2}[/tex] -[tex]36^{1/4}[/tex]=0

[tex](-6)^{2}[/tex] - [tex]6^{1/2}[/tex]=0

Which is not possible and a negative integer is not present in the square root.

Therefore we get the extraneous solution of the equation which is x= -4, and x = 6 is the solution of the equation.

It can be said that Dana is correct when she says that 0.6 divided by 30 gives 0.02 as a reminder.

Step-by-step explanation:

It is given that we need to rectify whether 0.6 divided by 30 = 0.02 or not.

Firstly, let us understand how does simplification work;

In mathematics, the operation and interpretation of a function to make it simple or easier to grasp is known as simplifying, and the process is known as simplification.

Now, let us understand what exactly is arithmetic;

According to the assertions, it deals with a number of operations in mathematics. Addition, subtraction, multiplication, and division are the four main arithmetic operators.

Now, let us equate the given condition that is;

=> 0.6 can also be expressed as 6/10

Now, let us divide the above numbers with each other as given in the question;

=> (6/10) ÷ 30

=> 6/300

On dividing both the numbers with each other we get;

=> 0.02 which can be expressed as 2/100

Therefore, it can be said that Dana is correct when she says that 0.6 divided by 30 gives 0.02 as a reminder.

Answer:

$37.96

Step-by-step explanation:

$9.49 x 4 = $37.96

The given 4th order polynomial equation only has real solutions,  x = √7  and x = –√7

The given equation is x⁴-14 x²+49 = 0.

This is a 4th degree polynomial equation.

Let p = x².

Then we can write x⁴-14 x²+49 = 0 as:

p²- 14p +49 = 0

This is a quadratic equation.

There are three ways to find the solutions of a quadratic equation:

Notice that p²- 14p +49 = 0 can be written as a perfect square:

(p - 7)² = 0

Hence, it has only single real solution:

p - 7 = 0

p = 7

Substitute p = 7 into p = x², we get:

x² = 7

x = ± √7

The solutions are, therefore,  x = √7  and x = –√7

The area of the rectangle having three identical circles inside is calculated as: (16√3 + 32) mm².

Area of rectangle = (length)(width)

The image of the three identical circles in the rectangle has been labelled as shown in the diagram attached below.

We need to find the measure of the length and width of the rectangle.

Radius = AB = BD = DF = FG = CD = HI = 2 mm

Length of the rectangle = AB + BD + DF + FG = 2 + 2 + 2 + 2

Length of the rectangle = 8 mm

Width of the rectangle = CD + DH + HI

CD = 2 mm

HI = 2 mm

Use the Pythagorean theorem to find the measure of DH

DH = √(FH² - DF²)

FH = 2 + 2 = 4 mm

DF = 2 mm

Substitute

DH = √(4² - 2²)

DH = √(16 - 4)

DH = √12 = 2√3 mm

Width of the rectangle = CD + DH + HI = 2 + 2√3 + 2

Width of the rectangle = 2√3 + 4

Area = (2√3 + 4)(8)

Area = (16√3 + 32) mm²
