The relation that is not a function, but whose inverse is a function are:

for every x in the domain of f, f -1[f(x)] = x, and

for every x in the domain of f -1, f[f -1(x)] = x

An inverse function is a characteristic that undoes the movement of another characteristic. A feature g is the inverse of a characteristic f if whenever y=f(x) then x=g(y). In different words, applying f and then g is the equal aspect as doing not anything. we are able to write this in terms of the composition of f and g as g(f(x))=x.

A few capabilities do not have inverse functions. for instance, remember f(x) = x2. There are numbers that f takes to four, f(2) = 4 and f(-2) = four. If f had an inverse, then the fact that f(2) = 4 might mean that the inverse of f takes four again to 2.

To discover the inverse function of an algebraic relation in terms of x and y, simply interchange the variables x and y, and resolve the equation for y. as an example, to discover the inverse of a relation y = x3, interchange x, and y after which clear up it for y. Then we get x = y3 ⇒ y = x1/3.

An inverse version can be represented by means of the equation xy=k or y=kx. this is, y varies inversely as x if there are a few nonzero steady k such that, xy=k or y=kx in which x≠0,y≠0 . assume y varies inversely as x such that xy=3 or y=3x.

Answer:

244Y

1E

Step-by-step explanation:

The given expression contains a fractional exponent and would be simplified through solving for it.

The reciprocal of power associated with the base is the degree of the radical signs.

For example: ∜7=7^1/4

In the given expression, there are two considerations. The number 243 has a power of 1/5, and the negative sign or say -1 also has a power of 1/5.

As a general rule, if the denominator of the fractional exponent is an odd number, as 5 in this case, the negative sign is extracted from the radical. Another way to look at it is -1 raised to any odd power would be -1.

Hence, (-243)^¹/₅ =-(243)^¹/₅

Factorizing the term,

243=3*3*3*3*3

Which can be expressed as 3^5

Hence,

-(243)^1/5=-(35)^1/5

As we know that (a^b)^c=a^bc, thus,

-(3^5^)1/5=-(3^5*1/5)= -(3^1)=-3

(-243)^¹/₅is simplified to -3

This can sometimes result in 2 possible values when using the Law of Sines, since sin(180°-x)=sin(x)

A uniform distribution has the data values evenly distributed throughout the range of the data. A bimodal distribution has two very common data values seen in a dot plot or histogram as distinct peaks.

A Dot Plot, also called a dot chart or strip plot, is a type of simple histogram-like chart used in statistics for relatively small data sets where values fall into a number of discrete bins (categories). A dot plot is similar to a bar graph because the height of each “bar” of dots is equal to the number of items in a particular category.

A dot plot is a graphical display of data using dots: Dot Plot is a graph for displaying the distribution of quantitative variable where each dot represents a value. For whole numbers, if a value occurs more than once, the dots are placed one above the other so that the height of the column of dots represents the frequency for that value.

The surface area of a rectangular cuboid cake which covered by a cookie crumble is approximately 35.1 m²

The cake can be depicted as in the attached picture with

length (l) = 4.45 meters

wide (w) = 4.06 meters

height (h) = 1 meter

It is a rectangular cuboid, or a right rectangular prism, which has 6 rectangular faces. Since all surfaces were covered by a cookie crumble except the bottom, hence, the surface areas are:

top face = l x w = 4.45 x 4.06 = 18.067 m²

left/right faces = 2 x w x h = 2 x 4.06 x 1 = 8.12 m²

front/back faces = 2 x l x h = 2 x 4.45 x 1 = 8.90 m²

Therefore, total surface area covered by the sprinkle is:

Total surface = 18.067 + 8.12 + 8.90  ≈ 35.1 m² ( to the nearest tenth)

C.It is zero.

The net force is the sum of all of the forces exerted on an object.

Identifying Forces

Force is measured in newtons, which is shortened to N. Additionally, force will always have a direction, like 5N up or 3N to the left.

Sometimes force will be negative to represent direction. A force moving down or to the left might be negative because moving down or to the left on an axis moves towards negative numbers.

Net Force

As stated above, the net force is the sum of all of the forces acting on an object. For example, if one object is being moved 5N to the left and 4N to the right, the net force will be 1N to the left.

On the other hand, if the forces are balanced, like 5N on both the left and right, then the forces cancel out. This leaves a net force of 0.

The measure of angles 1, 2 and 3 for fig in 11. are 100°, 80° and 100°. And for part 12. are 80°, 80° and 100° respectively.

For 11. part:

Considering two parallel lines l and m cut by a transversal p,

If two parallel lines are intersected by a transversal, each pair of interior angles on the same side of the transversal is supplementary.

m∠1 + 80° = 180°

m∠1 = 180° - 80°

m∠1 = 100°

Similarly, m∠1 + m∠2 = 180°

⇒ 100° + m∠2 = 180°

⇒m∠2 = 180° - 100°

⇒m∠2 = 80°

and also, m∠2 + m∠3 = 180°

⇒ 80° + m∠3 = 180°

⇒m∠3 = 180° - 80°

⇒m∠3 = 100°

Therefore, m∠1 = 100°, m∠2 = 80° and m∠3 = 100°.

For 13. part:

m∠3 = 100° (vertically opposite angle)

Now, let us suppose the angle adjacent to ∠3 be x then, m∠x will be simply equal to

m∠3 + m ∠x = 180° (Linear pair property.)

100° + m ∠x = 180°

m ∠x = 180° - 100°

m ∠x = 80°

Now, from the figure we can clearly see that,

m∠1 = m∠2 = m ∠x  = 80°(Corresponding angles are equal.)
