The composition of a function and its inverse is x. So an easy approach to solve this question is to find the composition of a function with itself. If the composition results in an answer "x", then this will mean that function and its inverse are the same.

Finding the composition for 1st option:
(fof)(x) = f(f(x))= \frac{ \frac{x-1}{x+5}-1 }{ \frac{x-1}{x+5}+5 } \\  \\ 
= \frac{ \frac{x-1-x-5}{x+5} }{ \frac{x-1+5x+25}{x+5} } \\  \\ 
= \frac{-6}{6x+24} \\  \\ 
=    \frac{1}{x+4}

Since the composition of the function with itself is not x, the function and its inverse are not the same.

Similarly, we can find the compositions of next 3 functions with themselves. The results of compositions are listed below:

(gog)(x)=g(g(x)) = x

(hoh)(x)=h(h(x))=\frac{4x-3}{7-x}

(kok)(x)=k(k(x))= x

Thus the option 2 and 4 are the correct answers i.e. these functions are the same as their inverse functions.

Patrick has $12,000 saved for medical school from gifts and summer jobs. Because the cost of college has risen each year, Patric
stealth61 [152]
Based on the given situation above about Patrick's savings, I can say that the best option for him in order to keep up with the increase 20 years after would be to utilize a compound interest account. The answer would be option B. Notice that with compound interest account, the amount he gets is around $31,000. Hope this helps.

How do you determine two angles which are coterminal to the given angles ?
Julli [10]

Answer:

Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. There are an infinite number of coterminal angles that can be found.

Step-by-step explanation:

i hope this helped you :)

A solid shape is made by joining two cones.
dlinn [17]

The surface area of the solid shape is the amount of space on it

The radius of the two cones is 2.93 cm

<h3>How to determine the radius?</h3>

The given parameters are:

  • Cone 1: slant height, l = 2r
  • Cone 2: slant height, L = 3r
  • Surface area = 135. 21 cm²

The surface area of the shape is calculated using:

T = πr(L + l)

So, we have:

135.21 = πr(2r + 3r)

Evaluate

135.21 = 5πr²

Divide both sides by 5π

r² = 135.21/5π

Evaluate the quotient

r² = 8.61

Take the square root of both sides

r = 2.93

Hence, the radius of the cones is 2.93 cm

-3/4x&gt;12 solve for x​
Ad libitum [116K]

Answer:

\Huge\boxed{\mathsf{\rightarrow X

Step-by-step explanation:

\Large\boxed{\mathsf{SUBJECT: MATH}}

Isolate x on one side of the equation.

Find the value of x.

First, multiply -1 from both sides.

(-3/4x)(-1)<12(-1)

Solve.

12(-1)=-12

3/4x<-12

Next, multiply 4 from both sides.

4*3/4x<4(-12)

Solve.

Multiply the numbers from left to right.

4(-12)=-48

3x<-48

Then, divide by 3 from both sides.

3x/3<-48/3

Solve.

Divide the numbers from left to right.

-48/3=-16

X<-16

\Large\boxed{\Rightarrow \mathsf{X

The correct answer is x<-16.
