Let f(x) = 7(x − 5) + 1 . If g is the inverse of f, write an equation for g(x)

To answer this question, we need to first multiply the left side of the given equation and write it as the difference of two squares. This can be done by using the difference of squares formula, which states that the difference of two squares can be written as the product of the square of the sum and the square of the difference.

The left side of the given equation can be written as:

(csc0+1)(csc0-1)

We can then apply the difference of squares formula to this expression to get:

(csc0+1)(csc0-1) = (csc0+1)(csc0-1)

Now, we can see that this expression is equivalent to cot 0 using the Pythagorean Identity. This identity states that the sum of the squares of the cosecant and cotangent of an angle is equal to 1. In this case, since (csc0+1)(csc0-1) = cot 0, we can use the Pythagorean Identity to rewrite the left side of the equation as (csc0^2 + cot0^2) = 1, which is equivalent to cot 0.

Therefore, the correct answer is C. Pythagorean Identity

If the width of a rectangle is two feet less than the length and the perimeter is 52 feet, then the length and width of the rectangle is 14 feet and 12 feet respectively

The width of a rectangle is two feet less than the length

Consider the length of the rectangle as x

Then the width of the rectangle = x - 2

The perimeter of the rectangle = 52 feet

The perimeter of the rectangle = 2(l + w)

Where l is the length and w id the width

Substitute the values in the equation

2(x + x - 2) = 52

2(2x - 2) = 52

2x - 2 = 52/2

2x - 2 = 26

2x = 28

x = 14 feet

Width of the rectangle = 14 - 2

= 12 feet

Therefore, the length and width of the rectangle is 14 feet and 12 feet respectively

The greatest common factor of polynomial  64xyz−36xy + 24x  is 4x

The greatest common factor of a polynomial is a monomial that divides all terms of the polynomial.

The given polynomial is:

64xyz−36xy + 24x

Notice that there are 3 terms:

64xyz

−36xy

π/32 is the area enclosed by the curve r= sin(8θ)

The given curve is polar curve and hence the area of the polar curve is given by:

Let A be the area of the curve so,

A = [tex]\int\limits^a_b {\frac{1}{2} r^2 } \, d\theta[/tex]

where a and b is the boundary at which r=0

so after equation r=0

sin(8θ) =0

=> sin(8θ) =0

=> 8θ = 0,π

=> θ = 0, π/8

so a=0 , b= π/8

now  

   A = [tex]\int\limits^a_b {\frac{1}{2} r^2 } \, d\theta[/tex]    ------(i)

 so   [tex]r^2[/tex] = (sin(8θ))^2

=>  [tex]sin^2[/tex] ( 8θ )

ans we know that

cos(2α) = 1 -  2[tex]sin^2[/tex] α

so   [tex]r^2[/tex]  = (1- cos(16θ) )/2

putting the value of r in the equation (i) we get :-

A = [tex]\int\limits^a_b {\frac{1}{4} *(1-cos(16\alpha ) } \, d\alpha[/tex]

=> 1/4* [tex]\int\limits^a_b {(1-cos(16\alpha ) } \, d\alpha[/tex]

Step-by-step explanation:

The positive intercept y is [tex]\sqrt{ }(3 / 2)[/tex], the negative  y intercept is y= [tex]-\sqrt{ }\left(\frac{3}{2}\right)[/tex], the equation of the tangent line at positive intercept is y=-0.48989x+1.2247,  the equation of the tangent line negative intercept  is y=0.48989x-1.2247.

(a). Here we have to find the positive y intercept

So letting x=0 in the given equation [tex]\frac{1}{(\mathrm{x}-1)^2+\mathrm{y}^2}+\frac{4}{(\mathrm{x}+1)^2+\mathrm{y}^2}=2[/tex]

x=0 implies

[tex]$$\begin{aligned}\frac{1}{(0-1)^2+y^2}+\frac{4}{(0+1)^2+y^2} & =2 \\\frac{1}{1+y^2}+\frac{4}{1+y^2} & =2 \\\frac{5}{1+y^2} & =2 \\5 & =2+2 y^2 \\5-2 & =2 y^2 \\\frac{3}{2} & =y^2 \\\mathrm{y} & =\sqrt{ }\left(\frac{3}{2}\right)\end{aligned}$$[/tex]

Therefore, the positive intercept y is [tex]\sqrt{ }\left(\frac{3}{2}\right)[/tex].

(b). Next we have to find the negative y intercept , the negative y intercept is y= [tex]-\sqrt{ }\left(\frac{3}{2}\right)[/tex]

The standard form of the linear equation of a straight line is given as  

2x - y + 17 = 0

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.    

                           Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

y=mx+c; where y and x stand for the respective axis's; 'm' represents the slope while 'c' represents the constant.

Let the point through which the line passes be P

Then, P= (-6,5)

m= 2

The equation of a straight line as a single point form can be found using the formula:

y-y1=m(x-x1)+c

y-(5) = 2(x-(-6))+c

y -5= 2(x+ 6)+c

Taking LCM

y - 5 =2(x+6)

on cross multiplying we get:

y - 5 = 2x + 12

 y  = 2x + 12 + 5

  2x - y + 17 = 0

Thus, Equation of the line comes out to be    2x - y + 17 = 0

The number of scholars who voted for the play named Wicked will be equal to 48.

This problem can be solved by using the concept of Ratio. It is given that the total number of students are 240. Now, the ratio of Annie to Wicked is equal to 5:2 and ratio of Wicked to Wizard Oz is equal to 2:3. If we assume that the number of people who voted for Annie is 'x', the number of people who voted for Wicked is 'y' and number of people who voted for Wizard Oz is 'z'. Now, we write the expressions as

x/y = 5:2; from this we get x = 5y/2                              ....(1)

y/z = 2:3; from this we get z = 3y/2                              ....(2)

x + y + z = 240                                                               ....(3)

We use the above values of equation (1) and (2) in equation (3) as

5y/2 + y + 3y/2 = 240

4y + y = 240

5y = 240

y = 48

Answer:

{x = -2, y = -1

Step-by-step explanation:

Solve the following system:

{-3 y + 8 x = -13

5 y - 3 x = 1

Choose an equation and a variable to solve for.

In the first equation, look to solve for x:

{-3 y + 8 x = -13

5 y - 3 x = 1

Isolate terms with x to the left-hand side.

Add 3 y to both sides:

{8 x = 3 y - 13

5 y - 3 x = 1

Hint: | Solve for x.

Divide both sides by 8:

{x = (3 y)/8 - 13/8

5 y - 3 x = 1

Perform a substitution.

Substitute x = (3 y)/8 - 13/8 into the second equation:

{x = (3 y)/8 - 13/8

5 y - 3 ((3 y)/8 - 13/8) = 1

Expand the left-hand side of the equation 5 y - 3 ((3 y)/8 - 13/8) = 1.

5 y - 3 ((3 y)/8 - 13/8) = 5 y + (-(9 y)/8 + 39/8) = (31 y)/8 + 39/8:

{x = (3 y)/8 - 13/8

((31 y)/8 + 39/8) = 1

Choose an equation and a variable to solve for.

In the second equation, look to solve for y:

{x = (3 y)/8 - 13/8

(31 y)/8 + 39/8 = 1

Isolate terms with y to the left-hand side.

Subtract 39/8 from both sides:

{x = (3 y)/8 - 13/8

(31 y)/8 = -31/8

Solve for y.

Multiply both sides by 8/31:

{x = (3 y)/8 - 13/8

y = -1

Hint: | Perform a back substitution.

Substitute y = -1 into the first equation:

Answer: {x = -2, y = -1
