The compositions f(g(x)) and g(f(x)) of functions f and g are shown on the graph. Which statements describe the compositions? Check all that apply. f(g(x)) = g(f(x)) for at least one value of x. The composition of f and g is commutative. f(g(0)) = 5 and g(f(–2.5)) = 5. Both f(g(x)) and g(f(x)) have the same domain. The graphs show that function composition is not commutative.

Answer:

First you divide 290.44 by 10 which would equal 29.044, then you would round both 4's down to 0 which would get you $29.

Answer:

(-14,12)

Step-by-step explanation:

Way 1: (little more complicated)
we know two things,
The two halves of the line have the same slope, and that the length from the endpoint to the midpoint is equal to the length from the midpoint to the other end point.
The slope is equal to: (6-9)/(4-(-5)) = -3/9 = -1/3
The length is equal to (using the Pythagorean theorem):
height = delta y = 9 - 6 = 3
length = delta x = 4 - (-5) = 9
3^2+9^2=hypotenuse^2
9+81 = h^2
h = sqrt(90)
So, the let's say point Q has the coordinate (a, b).
The formula of the slope would give us (b-9)/(a-(-5)) = -1/3
The formula of the hypotenuse would give us (b-9)^2+(a-(-5))^2 = 90
solving the system of equations, we would get that a = -14 and b = 12, so the point is (-14,12)
Make sure to be careful, however, because you will get two points with this system of equations. Only one works
Way 2:
since from point P to the midpoint we went to the left by 9 and up by 3, from the midpoint to point Q, we would go left by 9, and up by 3.
from the midpoint (-5,9), go left by 9, so x decreases by 9 to get (-14, 9).
go up by 3, so y increases by 3 to get (-14,12). This agrees with our other answer

The volume of the figure shown in the reference attachment, provided hereby with the question statement will be 6786 ft³.

As per the question statement and the reference attachment, we are provided with a figure and its dimensions.

We are required to calculate the volume of the concerned figure using the dimensional values provided.

To solve this question, we need to calculate the volumes of the bottom cuboidal part, and the top pyramidal part separately, and then add these volumes, to obtain our final desired answer.

Given, the dimensions of the bottom cuboidal part is (21ft by 18ft by 13ft).

We know that, volume of a cuboid = (length * breadth * height).

Therefore, volume of our concerned bottom cuboidal part

= (21 * 18 * 13) ft³

= 4914 ft³.

Also given, the dimensions of the top pyramidal part are as follows,

Base of the triangle  = 18 ft,

Altitude of the triangle  = 16 ft,

and length of the pyramid = 13 ft.

Therefore, Volume of the concerned pyramid

= [(1/2) * base * altitude * length]

= [(1/2) * 18 * 16 * 13] ft³

= (9 * 16 * 13) ft³

= 1872 ft³.

Therefore, Total volume of the concerned figure shown in the reference  attachment, provided hereby with the question statement will be

(4914 + 1872) ft³ = 6786 ft³

The rational sums are:

√16 + (-21/5)

√4 + 5

√36 + ∛27

The irrational sums are:

π + 24

√8 + π

3/4 + √27

√16 + (-21/5)

= 4 + (-21/5)

= 4 - (21/5)

= (20 - 21) / 5

= - 1/5

= -0.2

Hence, the sum can be expressed as p/q so it is a rational number.

π + 24

= 3.1428571429 + 24

= 27.1428571429

The sum is non-terminating, so it is an irrational number.

√8 + π

= 2.82842712 + 3.1428571429

= 5.97128426

The sum is non-terminating, so it is an irrational number.

√4 + 5

= 2 + 5

= 7

The sum is an integer so it is a rational number.

√36 + ∛27

= 6 + 3

= 9

The sum is an integer so it is a rational number.

3/4 + √27

= 3/4 + 5.1961524227

= 0.75 + 5.1961524227

= 5.9461524227

The sum is non-repeating so it is an irrational number.

The velocity of the cart b is found as 20/23 ft/s over the pulley.

For the given data in the question.

q's velocity is 2 feet per second.

Rope length is 39 feet.

Assume x is the distance between A and Q. (refer the image).

Assume y is the distance between Q and B. (refer the image).

As a result of the image,

x² + 12² = L²

Now, with respect to time t, differentiate the above equation.

2x(dx/dt) + 0 = 2L.(dL/dt)

For x = 5 ft and L = 13 ft

dL/dt = (5×2)/13 = 10/13

In the case of B,

y² + 12² = (39 - L)² ; from diagram.

Differentiating now,

2y(dy/dt) + 0 = -2(39 - L).(dL/dt)

At x = 5 ft and y = 23 ft.

dy/dy = -20/23

(A negative sign indicates the opposite direction)

The equation of the hyperbola is -(1/16) (x +4)² + (1/4) (y +2)² = 1

What is Hyperbola?

A hyperbola is a particular kind of smooth curve that lies in a plane and is classified by its geometric characteristics or by equations for which it is the solution set. A hyperbola is made up of two mirror images of one another that resemble two infinite bows. These two sections are known as connected components or branches.

The intersection of the two asymptotes is where the hyperbola's center is located. This is the key idea (-4,-2)

We have y orientation because the vertex at (-4,0) is above this location. The equation will take the form as a result.

-a (x + 4)

2 + b (y + 2)

In the case of certain a and b, 2 Equals 1.

Inputting (-4,0) reveals that b = 1/4.

Finally, requiring that y = x/2 be an asymptote reveals that a = 1/16.

-(1/16) (x +4)² + (1/4) (y +2)² = 1

Hence, The equation of hyperbola is -(1/16) (x +4)² + (1/4) (y +2)² = 1

The given parameters are

Slope, m = 5/4

Point, (x1, y1) = (1, 3)

A linear equation is represented as

y = m(x - x1) + y1

So, we have

y = 5/4(x - 1) + 3

This gives

y = 5/4x + 7/4

Hence. the linear equation is y = 5/4x + 7/4

Here, we have

(x, y) = (3, 0) and (0, 2)

A linear equation is represented as

y = m(x - x1) + y1

Where

m = (y2 - y1)/(x2 - x1)

So, we have

m = (2 - 0)/(0 - 3)

m = -2/3

A Linear equation may be defined as the one which can be represented in the form ax + b = 0 where a, b are coefficients and x is the independent variable. Since the equation only has one variable that is x then the linear equation will be rightly called as linear equation in one variable. We are given the equation -2(2x - _) + 1 = 17 - 4x. We solve the equation further which results as

-4x - _ + 1 = 17 - 4x

a) A occurs and B does not: 0.1817 = 18.17%.

b) Either occurs: 0.3434 = 34.34%.

A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.

In the context of this problem, we have two mutually exclusive events, meaning that they cannot happen together.

For item a, we have that:

The events are mutually exclusive, hence we can multiply the probabilities as follows:

p = 0.23 x 0.79 = 0.1817 = 18.17%.

The side length of the square that provides a counterexample to the statement square units in the area of a square is greater than or equal to the number of units in the perimeter is 2 Units.

A square is a kind of a 2D figure in which all the sides are equal.

We know that the absolute perimeter of a square is the sum of the lengths of all the total sides and as we see the area of a square is (side)².

Assuming that the whole square has four units completed for each side.

The square's circumference can be calculated as is 4 sides plus 4 fours, or as seen as 16 units.

Now the area of the square will be calculated as (4) ² = 16 sq units.

Now assuming that the total side length of the square about is 2 units.

The square's perimeter is calculated as (24) = 8 units, while its total area is calculated as (22) = 4 units.

∴ 2 units make up the side length that serves as a counterexample.
