The equations that will represent the reflected function are:

(c)  [tex]f(x)=5(\frac{1}{5})^{-x}[/tex] and;

(d) [tex]f(x)=5(5)^{x}[/tex]

If two functions share the same domain and codomain and have values that are consistent across all domain elements, they are said to be equivalent.

Consider the function,

[tex]f(x)=5(\frac{1}{5})^{x}[/tex]

Now,

Positive x-values and negative x-values are switched by a reflection over the y-axis, which also swaps the values of x and x.

So,

[tex]f(-x)=f(x)[/tex]

The reflection of the function f(x) across the y axis will be:

[tex]f(x)=5(\frac{1}{5})^{-x}[/tex]

Therefore, the equivalent function will be:

[tex]f(x)=5(\frac{1}{5})^{(-1)(x)}[/tex]

[tex]f(x)=5 \times ((\frac{1}{5})^{-1})^{x} \\f(x)=5(5)^{x}[/tex]

Therefore, the equations which represent the function are:

[tex]f(x)=5(\frac{1}{5})^{-x}[/tex] and;

[tex]f(x)=5(5)^{x}[/tex].

The equation formed using the given data is 195 = x + 12 and your final score is 183 points.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say your final score is x

Given that,

Your final score x is 12 points less than your friend's final score.

So,

x = friend final score - 12

Now,

Friend final score = 195

So,

x = 195 - 12

x + 12 = 195

195 = x + 12

Now,

x = 195 - 12 = 183

Hence "The equation formed using the given data is 195 = x + 12 and your final score is 183 points".

Answer:  110 grams of the 99% cocoa, and 90 grams of the 70% cocoa.

===================================================

Work Shown:

x = amount of the 99% cocoa

200-x = amount of the 70% cocoa

0.99x = amount of pure coca from the first batch

0.70(200-x) = amount of pure cocoa from the second batch

0.99x+0.70(200-x) = total amount of pure cocoa

0.99x+0.70(200-x) = 200*0.86

0.99x+0.70*200-0.70x = 200*0.86

0.99x+140-0.70x = 172

0.29x+140 = 172

0.29x = 172-140

0.29x = 32

x = 32/0.29

x = 110.344827586207

x = 110

200-x = 200 - 110 = 90

Lyle needs 110 grams of the 99% cocoa, and 90 grams of the 70% cocoa.

Both of these values are approximate.

By solving a system of equations, we can see that the chemist needs to use 375 mL of the 2% acid, and the other 225% of the 10% acid.

Let's define the variables that we will need to write our system of equations:

We know that the chemist wants to make 600mL of a 5% acid solution, so we can write the system of equations:

x + y = 600

x*0.02 + y*0.10 = 600*0.05

If we isolate y on the first equation, then we get:

y = 600 - x

Now we can replace that on the other equation so we get:

x*0.02 + (600 - x)*0.10 = 30

With this, we can get the value of x.

x*0.02 + 60 - x*0.10 = 30

-x*0.08 = 30 - 60 = -30

x = 30/0.08 = 375

So the chemist needs to use 375 mL of the 2% acid, and the other 225% of the 10% acid.

The kinetic energy is 1000J.

Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. It is the measure of the work that an object does by virtue of its motion.

Kinetic energy is the product of half the product of mass and the square of the speed.

K.I = 1/2 m v²

Here m = 20kg, v = 10m/s

K.I = 1/2 × 20 × 10²

    = 10 ×10²

    = 1000

Therefore the kinetic energy is 1000J.

Let me know if you have any questions

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)

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

        w = √49      ( ∵√49 = 7 )

         w = ±7

    So the solution of this quadratic equation 7 and -7

        w² = -49

        w  = √(-49)      ( ∵√49 = 7 )

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

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

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.

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

      (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

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

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]

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

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

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

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

So, the quadratic equation is

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.

Now, we also know that Area of triangle PAB is:

A = 1 / 2 (h ( 3 − 4 ) + 2 ( 4 − k ) − 3 ( k − 3 ) )

± 8.5 = 1 / 2 ( h ( - 1 ) + 2 ( 4 - k ) - 3 ( k - 3 ) )

± 17 = ( - h + 8 - 2 k - 3 k + 9 )

± 17 = ( 17 - 5 k - h )

When + 17 is there:
