The inverse of the function f(x) = 4(x - 3) is f⁻¹(x)=(x+12)/4.

A function that "undoes" another function is known as an inverse in mathematics. In other words, if f(x) generates y, then y entered into f's inverse creates x. x . Invertible refers to a function that has an inverse, which is represented by the symbol f1.

Inverse functions are functions that "reverse" one another in the broadest sense. If f, for instance, goes from a to b, then its inverse, f 1 f -1 f 1f, start superscript, minus 1, end superscript, must go from b to a.

Make f a function. Any horizontal line that crosses the f graph more than once indicates that f lacks an inverse. F has an inverse if there are no horizontal lines that cross the graph of f more than once.

Let f(x)=y

f(x)=4(x-3)

f(x)=y

y=4(x-3)

x=4(y-3)

x=4y-12

4y=x+12

y=(x+12)/4

Therefore, f⁻¹(x)=(x+12)/4

American adults believes in alien for the  given 95% confidence interval and sample surveyed is in the interval range of ( 0.66 , 0.78 ).

As given in the question,

Sample of American adults surveyed 'n' = 200

Percent of people believes in aliens are success  'p'= 72%

                                                                                      = 0.72

Percent of people who don't believes (failure) in aliens ' 1 - p'  = 1 - 0.72

95% Confidence interval that represents Americans adults who believes in aliens

value of z - score for 95% confidence interval = ± 1.96

Margin of error 'MOE'= (z-score)√p ( 1- p) /n

                                   = ( 1.96)√(0.72 × ( 1 - 0.72 )/ 200

                                   = 1.96 ( √0.2016 / 200)

                                   = 1.96 ×√0.001008

                                   = 0.063

Lower limit = p - MOE

                 = 0.72 - 0.063

                 = 0.66

Upper limit =  p + Margin of error

                 = 0.72 + 0.063

The surface area of this cylinder is 118.378 square yards. 3.6 yard is the height.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

For instance, the surface area of a cube is its surface area if we need to determine how much paint is needed to paint it. Square units are used to measure it at all times.

The terms "lateral surface area," "curved surface area," and "total surface area" refer to three different forms of surface area.

Surface area and volume are the cylinder's two main characteristics because it is a three-dimensional form. The area of the two circular bases combined with the cylinder's curved surface area equals the cylinder's overall surface area. Its volume is the three-dimensional area that a cylinder takes up.

Given that,

Surface area (A) of the cylinder = 118.378 square yards.

radius (r) = 2.9 yard

As we know, A = 2πrh + 2πr²

putting the values we get -

or, 118.378 = 2πr (h + r)

or, 118.378 = 2 × 3.14 ×2.9 × (h + 2.9)

or, 118.378 = 18.212 × (h + 2.9)

or, 6.5 = h + 2.9

or, h = 6.5 - 2.9

or, h = 3.6 yard

Thus, 3.6 yard is the height of the cylinder.

Given that x is in quadrant 3, its value for tan x=1/2 will be 206.565°, and its value for cos(206.565°) will be -0.894.

Trigonometry is the study of angles and the angular relationships between planar and three-dimensional shapes. The cosecant, cosine, cotangent, secant, sine, and tangent are among the trigonometric functions (also known as the circle functions) that make up trigonometry. The sine, cosine, and tangent are the three fundamental trigonometric operations. The cotangent, secant, and cosecant functions are derived from these three basic functions. On these functions, all trigonometrical concepts are built.

Here,

Tan x=1/2

x=tan⁻¹/²(1/2)

x=26.565°

As the x is in quadrant 3,

Step-by-step explanation:

[tex]\frac{3x-3}{5}=\frac{24+3x}{20}[/tex]          Original equation. A proportion can be set up so that

                              you can find x. One proportion can be one side over the

                              combine forming 24, which continues to be added to 3x.

                              15 and 5 can be combined to become 20.

20(3x-3)=5(24+3x) Now, cross multiply. This involves the distribution of one

                               term to the terms it's multiplied by. 20*3x=60x and

                               20*-3=-60. 5*24=120 and 5*3x=15x.

60x-60=120+15x     Now, the goal is to get x alone on one side. You can do

                                this by combining like terms. Subtract 15x from both

                                sides and add 60 to both sides.

45x=180                   Then, divide by 45 to get x by itself.

As per the congruency theorem, the two triangles are congruent.

Congruency theorem:

Congruency theorem states that "if all the three sides of one triangle are equal to all the three sides of another triangle, then both the triangles are congruent to each other."

Given,

Here we need to prove that  congruency theorem can be used to prove that △wut ≅ △vtu.

Let us consider triangles WUT and VTU.

And in these triangles:

=> WU≅VT

And in those one, ∠T≅∠U,

Therefore, m∠T = m∠U = 90°

Here the side TU is common.

Now, we have to note that triangles WUT and VTU are right triangles, because m∠T = m∠U = 90°.

Then the side TU is common leg and sides WU and VT are hypotenuses.

Therefore, the HL theorem states: if the hypotenuse (WU) and one leg  (TU) of a right triangle (ΔWUT) are congruent to the hypotenuse (VT) and one leg (TU) of another right triangle (ΔVTU), then the triangles are congruent.

Step-by-step explanation:

If the pond now contains 320 gallons of water, number of weeks it has been since the pond was at full capacity is 5 week.

Given that, a full pond containing 625 gallons of water begins losing its water at a rate of 20% per week.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here, number of gallons water being used for x weeks is

625-320=305 gallons

Now, number of gallons of water used in a week= 20% of 305

= 20/100 ×305

= 0.2 ×305

= 61 gallons

So, number of weeks = x=305/61

= 5

Therefore, if the pond now contains 320 gallons of water, number of weeks it has been since the pond was at full capacity is 5 week.

The equation of line s is y + 7 = -7/6(x - 7).

What is slope of a line?

A line's steepness and direction are measured by the line's slope. A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates,  Δy, Δx respectively. Consequently, it is possible to write the change in y coordinate with respect to the change in x coordinate as m = Δy/Δx

Given equation of line r is y = 6/7x+1.

The slope of line r is m = 6/7

The slope of the line that is perpendicular to line r is -1/m = - 7/6.

The equation of line that passes through the point (x₁, y₁) with slope m is y - y₁ = m(x - x₁).

Putting m = - 7/6, x₁ = 7 and y₁ = -7 in y - y₁ = m(x - x₁):

y - (-7) = - 7/6(x - 7)

y + 7 = - 7/6(x - 7)

a) Equation for length and width of the rectangular rug be [tex]x^{2}[/tex] + 8x - 42 = 0

b) Width of the rectangular rug be 3.5 feet

c) Diagonal of the rectangle is 12.5 feet

What is the area of the rectangle?

The area of ​​a rectangle is the area occupied by the rectangle within its four sides or boundaries.

The area of ​​a rectangle depends on its sides. Basically, the formula for area is equal to the product of the length and width of a rectangle. The perimeter of a rectangle is equal to the sum of all its four sides

It is given that area of a rectangular rug id 42 square feet. The rug is 8 feet longer than its wide

a) Let the width of the rectangular rug be x feet

Length of the rectangular rug = (x+8) feet

area of rectangular rug = Length × width = x × (x + 8) = [tex]x^{2}[/tex] + 8x

area of rectangular rug = 42

[tex]x^{2}[/tex] + 8x = 42

[tex]x^{2}[/tex] + 8x - 42 = 0

Therefore, equation for length and width of the rectangular rug be [tex]x^{2}[/tex] + 8x - 42 = 0

b) If the length of the rectangle is 12 feet

Area of rectangle = 42 square feet

length × width = 42 square feet

12 × width = 42 square feet

width = 42/12 = 3.5

Therefore, width of the rectangular rug be 3.5 feet

c) Length of the diagonal of the rectangle = [tex]\sqrt{length^2+width^2}[/tex]

= [tex]\sqrt{12^2+3.5^2}=\sqrt{144+12.25}=\sqrt{156.25}= 12.5[/tex]
