Answer 1

1) Sheryl was wrong, the solution of w² = 49 and w² +49 = 0 are not same.

2) The solution of 4x² - 9 = 0 this quadratic equation is 3/2 and -3/2 through using factoring method.

3)

The solution of  4x² - 20x = 11 is 11/2 and -1/2, through using completing the square method.The solution of  x² + 7x + 12 = 0 is -4 and -3, through using factoring method.

4) The solution of both quadratic equations will give same results.

Explanation:

1) Sheryl says that the solutions of the quadratic equations w² = 49 and

w² +49 = 0 are the same. Do you agree with Sheryl? Justify your answer.

Solution:-

 According to Sheryl says that the solutions w² = 49 and w² +49 = 0 are the same.

Let's find the solution of given quadratic equations

w² = 49

        w = √49      ( ∵√49 = 7 )

         w = ±7

    So the solution of this quadratic equation 7 and -7

w² + 49 = 0

        w² = -49

        w  = √(-49)      ( ∵√49 = 7 )

         w = ±7 √-1       ( ∵√-1 = i )

   So the solution of this quadratic equation 7i and -7i

Both solutions are not same.

2. Patricia says that it's more appropriate to use the method of factoring

than extracting square roots in solving the quadratic equation

4x² - 9 = 0. Do you agree with Patricia? Explain your answer.

Solution:-

Patricia says that it's more appropriate to use the method of factoring

than extracting square roots in solving the quadratic equation

       4x² - 9 = 0.

We are agree with Patricia, the method of factoring is very easy to learn and best way to deliver the solution of this quadratic equation.

Now, let's solve that quadratic equation through factoring method.

  4x² - 9 = 0.

      (2x)² - (3)² = 0                {∵ a²-b²= (a-b)(a+b)

   (2x-3)(2x+3) = 0

    If       (2x-3) = 0  

               2x-3 = 0      

                   2x = 3

                      x = 3/2

   And if  (2x+3) = 0

               2x+3 = 0      

                   2x = -3

                      x = -3/2

The solution of 4x² - 9 = 0. is 3/2 and -3/2.

3. If you are to choose between completing the square and factoring in

finding the solutions of each of the following equations, which would you

choose? Explain and solve the equation using your preferred method.

a. 4x² - 20x = 11

b. x² + 7x + 12 = 0.

Solution:-

a. 4x² - 20x = 11

For solve this quadratic equation, we can use completing the square method, because this equation is very hard to get it's factors.

So,

    4x² - 20x = 11

[tex]x^2-5x+(\frac{5}{2})^2 = \frac{11}{4} +(\frac{5}{2})^2\\x^2-2\times \frac{5}{2} \times x+(\frac{5}{2})^2 = \frac{11}{4} +\frac{25}{4}\\(x-\frac{5}{2})^2 = \frac{11+25}{4}\\(x-\frac{5}{2})^2 = \frac{36}{4}\\(x-\frac{5}{2})^2 = 9\\(x-\frac{5}{2})^2 = (3)^2\\(x-\frac{5}{2}) = \pm (3)\\\\[/tex]

 For taking + sign,

x - [tex]\frac{5}{2}[/tex] = 3

    x = 3 + [tex]\frac{5}{2}[/tex]

    x = [tex]\frac{6+5}{2}[/tex]

     x = [tex]\frac{11}{2}[/tex]

  For taking - sign,

x - [tex]\frac{5}{2}[/tex] = -3

    x =  [tex]\frac{5}{2}[/tex] - 3

    x = [tex]\frac{5-6}{2}[/tex]

     x = [tex]\frac{-1}{2}[/tex]

The solution of  4x² - 20x = 11 is 11/2 and -1/2, through using completing the square method.

b. x² + 7x + 12 = 0.

For solve this quadratic equation, we can use factoring method, because that is very easy to get it's factors.

So,

            x² + 7x + 12 = 0

      x² + 4x +3x + 12 = 0

          x(x+4) +3(x+4) = 0

                 (x+4)(x+3) = 0

                If       (x+4) = 0  

                           x+4 = 0      

                               x = -4

             And if  (x+3) = 0

                           x+3 = 0      

                               x = -3

The solution of  x² + 7x + 12 = 0 is -4 and -3, through using factoring method.

4. The values of a, b, and e of a quadratic equation written in standard form are -2, 8, and 3, respectively. Another quadratic equation has 2, -8, and -3 as the values of a, b, and c, respectively. Do you agree that the two equations have the same solutions? Justify your answer.

Solution:-

We know that the standard form of quadratic equation is

ax²+bx+c = 0

From question we have two values of a,b and c.

For 1st quadratic equation the value of a,b and c is -2, 8, and 3, respectively.

So, the quadratic equation is

-2x²+8x+3 = 0

For 2nd quadratic equation the value of a,b and c is 2, -8, and -3, respectively.

So, the quadratic equation is

2x²-8x-3 = 0

Now, we have to find the solution of both equations are same or not.

So, the solution of 1st quadratic equation

       -2x²+8x+3 = 0

           2x-8x-3 = 0            (multiplying - with both sides)

Now, this equation convert in the form of 2nd quadratic equation. So we can say that the solution of both quadratic equations will give same results.

a house at the bottom of a hill is fed by a full tank of water 5.pm deep and connected to the house by a pipe that is 110m long at an angle of 58 degrees from the horizontal

Answers

The water gauge pressure at the house will be 9.63×10⁵ N/m².

Firstly we will be calculating the total height which will comprise of height from tank to house and elevated height. The formula for total height will be -

Total height = 5 + 110 sin 58°

Keep the value of sin 58° in formula and performing multiplication followed by addition

Total height = 5 + 110×0.848

Total height = 5 + 93.28

Total height = 98.28 meters

Now, calculating the water gauge pressure at house. The formula to be used is -

P = ρ×g×h, where P is pressure, ρ is density of water, g refers to acceleration due to gravity and h represents total height. We are aware that density of water is 1000 kg/m³ and accelerate due to gravity is 9.8 m/s².

Keep the values in formula to find the gauge pressure.

P = 1000 × 9.8 × 98.28

Performing multiplication

P = 963,144 N/m² or 9.63×10⁵ N/m²

Hence, the water gauge pressure at the house will be 9.63×10⁵ N/m².

solve for x32=10+ x/2

Answers

Answer:

x=44

Step-by-step explanation:

x32=10+x/2

Multiply the 2 from x over 2 to reverse the division equation.

2*x32=10+x/2*2

That results in 2 multiplying 32x and 2 multiplying the 2 in x over 2.

Because multiplication is the reverse of division, the 2's will cancel out and reduce x over to 2 to simply x.

2*32 is 64, include the x before the 64 just like the given equation exemplifies with the x before the 32.

The equation looks like the following once put together: x64=10+x

Subtract the x from the 10+x side of the equation underneath the x64.

x64=10+x

-x          -x

Which equals x63=10.

To receive the answer to this question, you have to divide the 63 on both sides.

63 divided by 63x leaves you with just the x.

63 divided by 10 leaves you with 6.3 in decimal form.

Thus, x equals 6.3.

To check if it's right, insert 6.3 for both x's.

(6.3)*32=10+(6.3)/2

Solve.

201.6=10+3.15

201.6=13.15

Clearly, this doesn't work.

So, I'm assuming you actually meant: 32=10+x/2.

Hence, you would multiply 2 on both sides.

2*32=10+x/2*2

We've established that 32*2 is 64 and the 2's would cancel out.

64=10+x

Subtract the 10 on both sides.

54=x

To see if this one is correct, plug in 54 to the x.

32=10+(54)/2

Divide 54 by 2 which equals 27.

32=10+27

32=37

Nope, that doesn't work either.

Thus, instead of multiplying by 2, we would first need to subtract the 10.

32=10+x/2

-10 -10

32-10 is 22 and it would leave the other side with just x over 2.

22=x/2

Now, we would have to multiply the 2 on both sides.

22*2=44 and x/2*2 gives us x.

So, 44=x.

Let's check.

32=10+(44)/2

32=10+22

32=32

Finally, we have our match.

In conclusion, x=44.

Hope this helps.

Abstract:

background: In randomised studies, first-rate of life measures are mechanically utilised as outcomes. contraptions with several subscales provide researchers the choice of combining a few or all scales right into a unmarried composite score. There is probably diverse clinically and scientifically sound alternative subscale combinations for the predominant outcome degree.foremost findings: The statistical effectiveness of diverse subscale combinations is decided with the aid of the relative effect size of the intervention on every subscale as well as the correlation between the subscales. easy formulae may be installed to determine the relative statistical efficiency of each clinically appropriate subscale aggregate. Hypothetical situations imply that the variety of participants required in a scientific trial is probably twice as huge for a few subscale combinations as for others.

Answers

The number of 8-inch long pieces of ribbon that the other class cut is 9.

What is subtraction?

Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.

Given that Students in 3 art classes cut 728 inches of ribbon into 8-inch long pieces. Therefore, the number of ribbon that 3 classes together cut is,

Number of ribbon cut by 3 classes together = 728 inches / 8 inches = 91

Further, it is given that two of the classes together cut 656 inches of ribbon. Therefore, the number of ribbon that 2 classes together cut is 656.

Number of ribbon cut by 2 classes together = 656 inches / 8 inches = 82

Now, the number of  8-inch long pieces of ribbon that the other class cut can be written as,

Number of pieces cut by other class

= Number of ribbon cut by 3 classes together - Number of ribbon cut by 2 classes

= 91 - 82

Triangle EFG is similar to triangle HIJ. Find the measure of side HI.
Round your answer to the nearest tenth if necessary. Figures are not
drawn to scale.

Answers

The measure of side HI is 10.74 for the triangle EFG which is similar to HIJ.

Similar triangles are those triangles which have corresponding sides in proportion to each other and the corresponding angles of two triangles are equal to each other. Similar triangles look the same but they differ in terms of the sizes of the two triangles.

In short, If two triangles are similar that means,

All corresponding angle pairs of triangles will be equal.

All corresponding sides of triangles will be proportional.

Now, it is given in the question that ΔEFG is similar to ΔHIJ then, their corresponding sides will be in proportion.

⇒ GE/EF = HJ/HI

⇒ 19/34 = 6/HI

⇒ HI = 6 x 34/19

⇒ HI = 10.74

Therefore, the measure of side HI is 10.74.

Calculate the value of the x (with reason) ​

Answers

in fig. 3.1 the value of  x  is 20° , in fig. 3.2 the value of  x  is 40° ,  in fig.  the value of  3.3 x  is 10° ,  in fig. 3.4 the value of  x  is 120°.

WHAT IS ANGLE?

In planar geometry, an angle is a shape made up of two rays or lines that share an endpoint. The English word "angle" derives from the Latin word "angulus," which means "corner." The vertex and the two rays are referred to as the sides of an angle, respectively, and are the shared termini of two rays.

CALCULATION

3.1

straight lines makes an angle of 180° thus ,

              x + 2x + 120 = 180

                3x = 60

                  x = 20°

3.2

    sum of the angles of triangle is = 180°

     105 + 35 + x = 180

      140 + x = 180

       x = 40°

3.3

       since it is an isoceles triangle so the opposite angles to equal sides are equal

140 + 4x = 180

4x = 40

x = 10°

3.4

parallel  line theorem  state that alternate angles are equal

so ,

    180= x + 60

x = 120 °

Describe and correct the error in solving the equation below. (2 pts)

Answers

Answer: 3x=13

Step-by-step explanation:

The person is blind. They did what they were supposed to except the fact that they didn't multiply the 8 by the -1.

Answer: The error is in step 3

Explanation:

In step 2, they multiplied both sides by 8 to clear out the fractions. In step 3, they forgot to distribute the 8 to each term inside the parenthesis.

This is what the steps should look like

[tex]\frac{3\text{x}}{8}-1=\frac{5}{8}\\\\\\8\left(\frac{3\text{x}}{8}-1\right)=8\left(\frac{5}{8}\right)\\\\\\3\text{x}-8 = 5\\\\\\3\text{x} = 13\\\\\\\text{x} = \frac{13}{3}\\\\\\[/tex]

In step 4, we added 8 to both sides. Afterward, divide both sides by 3 to fully isolate x.

Solve the inequality. Graph the solution, if possible.

24. |m|greater than or equal to 10

Answers

We can use inequality, 24. |m| greater than or equal to 10 then the possible to value is =  |14|.

What is Inequality :

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Based on the given conditions, formulate,

24. |m| greater than or equal to 10

So, we can write,

24 + m ≥ 10

m ≥ 10 - 24

We can sum or difference,

m ≥ -14

Then,

|m| ≥ |-14|

Hence,

|m| ≥  |14|

Therefore,

24. |m| greater than or equal to 10 then the possible to value is =  |14|.

The answer is (3,4) because you use the midpoint formula

−4xy(5x² – 9xy – y²)

Answers

The abbreviated formula is -4xy (5x(x-y) - y(4x + y)).

The answer to the question is that common words outside of the brackets can be used to simplify the supplied equation.

Therefore,

Required expression is -4xy(5x2 - 9xy -y2), which is equivalent to -4xy(5x2 - 5xy - 4xy -y2).

The final formula will be: -4xy(5x(x-y) - y(4x + y)).

Therefore, the abbreviated formula is: -4xy(5x(x-y) - y(4x + y)).
