Number 3 determine the inverse

Answers

Answer:

So Imma use the explanation area to answer this (I'll link a video on how I solved this.)

Step-by-step explanation:

F(x)=1/3(-5x -4)³-3 (Multiply 1/3 by -5x & -4. Be sure to move the unused parts of the equation down)

F(x)= -1.66x -1.33³-3 (Here we need to use our exponent)

F(x)= -1.66x -2.37 -3 (Here we need to subtract -3 from -2.37)

F(x)= -1.66x - 0.629 (You need to subtract 0.629 from the right side and left side)

-0.629 =  -1.66x (Now since X is attached by multiplication, we need to divide both sides by -1.66)

0.378 = x (this means that your inverse is 0.378)

F(x) =x+4/3 and g(x) = 3x – 4 Verify that the functions below are inverses by showing that (f o g)(x) = x and (g o f)(x) = x.

Answers

Answer:

The answer is below

Step-by-step explanation:

A composite function is a function which is placed inside another function, this type of function can be calculated by substituting one function into another function.

If two functions g(x) and f(x) are inverses, then each will reverse the effect of the other. That is, (f○g)(x)=f(g(x))=x and (g○f)(x)=g(f(x))=x.

Given that F(x) =(x+4)/3 and g(x) = 3x – 4

a) (f o g)(x) = f[g(x)]

   = f(3x - 4)

   = [(3x - 4) + 4]/3

   = [3x - 4 + 4]/3

   = 3x / 3

   = 3

b) (g o f)(x) = g[f(x)]

   = g[(x + 4)/3]

   = 3(x + 4)/3 - 4

   = x + 4 - 4

   = x

We can see that (f o g)(x) = (g o f)(x) = x. Hence the functions are inverse functions.

Solve each equation: -5(7-8x)-7x=-(3x+1)

Answers

Answer:

x = 17/18

Step-by-step explanation:

-5(7-8x) -7x = -(3x+1)

-35 + 40x - 7x = -3x - 1

-35 + 33x = -3x - 1

33x + 3x = -1 + 35

36x = 34

x = 34/36

x = 17/18

The answer is H. You have to distribute 6 3/4 into -11.5. The answer is negative because a positive (+) times a negative (-) is a negative (-).

Answer:

77 5/8

Step-by-step explanation:

a) Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4

= 24/4

b) Add the answer from the previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

c) Write a previous answer (new numerator 27) over the denominator 4.

Conversion a decimal number to a fraction: -11.5 = -115/10

= -23/2

a) Write down the decimal -11.5 divided by 1: -11.5 = -11.5/1

b) Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

-11.5/1

= -115/10

c) Simplify and reduce the fraction

-115/10

= -23 * 5/2*5

= -23 * 5/2*5

= -23/2

Multiple: 27/4

* (-11.5) = 27 · (-23)/4 times5

= -621/8

A tent company makes one kind of tent that is shaped like a triangular prism. The approximate dimensions of the tent are 30 times 1/2 plus 30 times 1/2 plus 49.5 plus 49.5 plus 54 equals?

Answers

Answer:

The answer is below

Step-by-step explanation:

A triangular prism is a polyhedron (three dimensional shape) made up of two equal triangles, two equal rectangle and a base rectangle.

The total surface are of a triangular prism is given as:

A = bh + 2ls + lb

where b is the base of the triangle, h is the height of the triangle, l is the length of the base rectangle and s is the length of the slant side of the triangle.

Given that:

b = 6 ft, s = 5.5 ft, h = 5 ft, l = 9 ft.

Therefore:

A = (6 * 5) + 2(9 * 5.5) + (9 * 6) = 183 ft²

Therefore 183 ft² of fabric is needed to make the tent

Answers

Answer:

135

Step-by-step explanation:

Ratio = 3 : 9

Angles are : 3x , 9x

3x + 9x = 180         {supplementary angles}

   12x   = 180  {divide both side by 12}

       x = 180/12

x = 15
