Answer: -4.25 ≤ x ≤ 6.25

Step-by-step explanation:

The midpoint of a segment is located at the same distance of each of the endpoints of the segment.

The midpoint is at x = 1.

The length of the segment is 10.5, if we divide it by two we have:

10.5/2 = 5.25

Now, if we want the endpoints to be at the same distance of the midpoint, then the endpoints will be:

Xmax = midpoint + 5.25

Xmin = midpoint - 5.25

Then the extremes are:

Xmax = 1 + 5.25 = 6.25

Xmin = 1 - 5.25 = -4.25

Then this segment can be written as:

Xmin ≤ x ≤ Xmax

-4.25 ≤ x ≤ 6.25

Step-by-step explanation:

16x+9=9y-2x

+2x         +2x

18x+9=9y

Answer:

please see explanation below

Step-by-step explanation:

Let's solve for x.

16x+9=9y−2x

Step 1: Add 2x to both sides.

16x+9+2x=−2x+9y+2x

18x+9=9y

Step 2: Add -9 to both sides.

18x+9+−9=9y+−9

18x=9y−9

Step 3: Divide both sides by 18.

18x /18 = 9y−9 /18

x= 1 /2y+ (−1 /2)

Answer:

1/2y+(-1/2)

OR

Let's solve for y.

16x+9=9y−2x

Step 1: Flip the equation.

−2x+9y=16x+9

Step 2: Add 2x to both sides.

−2x+9y+2x=16x+9+2x

9y=18x+9

Step 3: Divide both sides by 9.

9y /9 = 18x+9 /9

y=2x+1

Answer:

y=2x+1

Answer:

[tex]x^2+4x -\frac{1}{2} lnx + \frac{2}{13} ln(x-2) + C[/tex]

Step-by-step explanation:

Given the integrand [tex]\int\limits{\dfrac{2x^3 - 2x + 1}{x^2-2x} } \, dx[/tex], before evaluating the integral function, we will need to simplify the function first by applying long division as shown in the attachment.

Hence the partial form of the function [tex]\dfrac{2x^3 - 2x + 1}{x^2-2x} } = 2x+4 + \frac{6x+1}{x^2-2x}[/tex]

Integrating its partial sum

[tex]\int\limits \dfrac{2x^3 - 2x + 1}{x^2-2x} }dx = \int\limits (2x+4 + \frac{6x+1}{x^2-2x})\ dx\\\\= \int\limits {2x} \, dx + \int\limits {4} \, dx + \int\limits {\frac{6x+1}{x^2-2x} \, dx\\ = \frac{2x^2}{2}+4x -\frac{1}{2} \int\limits{\frac{1}{x} } \, dx + \frac{2}{13} \int\limits{\frac{1}{x-2} } \, dx[/tex]

[tex]= \frac{2x^2}{2}+4x -\frac{1}{2} lnx + \frac{2}{13} ln(x-2) + C[/tex]

[tex]= x^2+4x -\frac{1}{2} lnx + \frac{2}{13} ln(x-2) + C[/tex]

Answer:

177 cm²

Step-by-step explanation:

Area of circle = [tex]\pi[/tex]r²

Radius = diameter/2 = 15/2 = 7.5

Therefore,

Area = 22/7 × 7.5 × 7.5

        = 176.7 = 177 cm²

Answer:

The answer is

Step-by-step explanation:

Area of a circle is given by πr²

where

r is the radius

From the question we were given the diameter

To find the radius using the diameter we use the relation

[tex]radius = \frac{diameter}{2} [/tex]

diameter = 15 cm

[tex]radius = \frac{15}{2} [/tex]

radius = 7.5 cm

Substitute the value into the above formula and solve for the area

Area = (7.5)²π

= 56.25π

= 176.714586

We have the final answer as

176.71 cm² to 2 decimal places

Answer:

2 real roots

2 imaginary roots

Step-by-step explanation:

So we have the function:

[tex]f(x)=x^4-15x^2-16[/tex]

And we want to find its zeros.

First, let u equal x². So:

[tex]0=u^2-15u-16[/tex]

Factor:

[tex]0=(u-16)(u+1)[/tex]

Zero Product Property:

[tex]u-16=0\text{ or }u+1=0[/tex]

Add 16; Subtract 1. Replace u:

[tex]x^2=16\text{ or }x^2=-1[/tex]

Take the square root:

[tex]x=\pm 4\text{ or }x=\pm i[/tex]

So, our solutions are 2 real roots and 2 imaginary roots.

Answer:

-6-4=4x-2x

10=2x

x=2÷10

x=5

There are 2 solutions with absolute value equations.

1. |2x-6| = 4x+4

Remove absolute value:

2x-6 =4x + 4

Subtract 4x from both sides:

-2x -6 = 4

Add 6 to both sides:

-2x = 10

Divide both sides by -2:

X = -5

2nd solution

Remove absolute value and add a negative sign to the right side:

2x-6 = -4x -4

Add 4x to both sides::

6x-6 =-4

Add 6 to both sides:

6x = 2

Divide both sides by 6:

X = 2/6

X = 1/3

The two answers are x = -5 and x = 1/3

Step-by-step explanation:

The function f(x) = 1050 is a polynomial with degree zero option (A) this is a polynomial function of degree zero with a leading coefficient of 1,050 is correct.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

The question is incomplete.

The complete question is:

Determine if the function is a polynomial function. If the function is a polynomial function, state the degree and the leading coefficient. If the function is not a

polynomial, state why.

F(x) = 1,050

We have a function:

f(x) = 1050

We can write it as:

f(x) = 1050x⁰

x⁰ = 1

As we know from the definition of the polynomial:

The polynomial is a combination of the variable and constant with powers of x that are non-negative.

f(x) = 1050 is a polynomial function of degree zero with a leading coefficient of 1,050.

Thus, the function f(x) = 1050 is a polynomial with degree zero option (A) this is a polynomial function of degree zero with a leading coefficient of 1,050 is correct.

Answer:      " x = - 2.5 " .

___________________________________________

Step-by-step explanation:

Given:  

         9(3x + 7) - 3.5  = - 8 ;   Solve for "x" ;

First: Let us add "3.5" ;  to both sides of the equation:

    9(3x + 7) - 3.5   = - 8    ;

                  + 3.5  = + 3.5 ;

___________________________________________

to get:    

    9(3x + 7)           =  - 4.5 ; [Note that " -3.5 + 3.5 = 0" ; [Cancels out to "0".].  

Second: Let us expand the expression on the "left-hand side" of the equation.

 "  9(3x + 7) " ;

Note the "distributive property" of multiplication:

     " a(b + c) = ab + ac " ;

As such:

       9(3x + 7)  =  9(3x) + 9(7)  = 27x + 63 ;

Third:

Now, replace this term for the original expression, on the "left-hand side" of the equation;  & Rewrite the equation:

   27x + 63 = - 4.5 ;

Fourth:  Now, we can divide each side of the equation by "9" ;

(27x + 63) / 9 = (-4.5)/9 ;

to get:

(27x/9) + (63/9) = (-4.5/9) ;

  to get:

   3x + 7 = -0.5 ;            

Fifth:

Subtract "7" ; from Each side of the equation:

   3x + 7   =  -0.5 ;

        - 7   =   - 7  ;

___________________________________________

to get:

  3x          =   -7.5 ; [Note that " +7 - 7 = 0" ; [Cancels out to "0".]  ;

___________________________________________

Sixth:  Divide each side of the equation by "3";  

            to isolate "x" on one side of the equation; & to solve for "x" ;

___________________________________________

  3x / 3  =  -7.5 / 3 ;

 to get:

    x = - 2.5 .

___________________________________________

Hope this helps!  

 Best wishes!

Step-by-step explanation:

Hey there!

Given;

[tex]9(3x + 7) - 3.5 = - 8[/tex]

Perform the operations in left side.

[tex]27x + 63 - 3.5 = - 8[/tex]

Simplify the like terms and find value of x.

[tex]27x + 59.5 = - 8[/tex]

[tex]27x = - 8 - 59.5[/tex]

[tex]27x = - 67.5[/tex]

[tex]x = \frac{ - 67.5}{27} [/tex]

Therefore the value of x is "-2.5".

Check;

9(3×-2.5+7) - 3.5 = -8

-4.5 - 3.5 = -8

-8 = -8 (True).

Answer:

A P value of 0.05 is considered as the gold standard of the significance level, but it depends on the type of study

Step-by-step explanation:

The scientists make experiments to collect relevant data and their conclusions are often based on statistical analyses of their results. In scientific method, the correct interpretation of the statistical results may be critical for obtaining conclusions. The statistical significance level or 'P value' is an index aimed at summarizing the results of a research. Karl Pearson created the term P value in 1900 and used this index in association with his chi-square test. The P-value can be defined as the probability of observing statistical results that are equal to or more extreme than the one observed when null hypothesis is correct. A P value of 0.05 is generally considered to be correct in many studies; however, this index may change according to the level of significance required for a particular case. It is also important to note the factors that may lead to errors in P value calculation (P>0.05): small sample sizes, errors in study design, errors in measurement methods, etc.
