Answer:

The plot coordinates are (3,3).

Step-by-step explanation:

Given:

A fucntion f(x) and its inverse is f-1(x)

To find :

The plot of the coordinates for the intersection.

Solution:

Now we know that inverse fucntion is changing the y=f(x) and then

changing to x to y and y to x

So given function is f(x)

Inverse function is y,

But value of inverse function is f-1(x)

So y=f(x)=f-1(x)

Therefore it becomes

y=x

Hence the value is y=x coordinates

Answer:

1.631

1.861

-2.322

Step-by-step explanation:

The value of logarithm log₅20 is 1.861.

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x.

The given logarithms are log₃6, log₅20 and log₂(1/5).

We have change of base formula: logₐx= logₙx/logₙa

Here, log₃6 = log₁₀6/log₁₀3

= 0.7781/0.4771

= 1.6308

≈ 1.631

log₅20 = log₁₀20/log₁₀5

= 1.3010/0.6989

= 1.8614

≈ 1.861

log₂(1/5) = log₁₀(1/5)/log₁₀2

= -0.6989/0.3010

= -2.3219

≈ -2.322

Therefore, the value of logarithm log₅20 is 1.861.

495 students in 7th grade do not ride a car to school

Step-by-step explanation:

Number of students walking or riding a bike = 8

Number of students who ride a car = 15

Number of students who take the bus = 25

Total students in the sample = 48

⇒ Percentage of students who rides a car in the sample = 15/48 × 100 = 31.25%

Total number of students = 720

Number of students who ride a car = 31.25/100 × 720

                                                           = 225

Number of students who do not ride a car to school = 720 - 225 = 495

Answer:

36 Yellow pieces

Step-by-step explanation:

-Given the total number of pieces is 80 and the probability of choosing a yellow piece at random is 0.45.

-To find the number of yellows pieces in the container, we multiply its probability by the total number of pieces;

[tex]n_y=P(yellow)\times n\\\\=0.45\times 80\\\\=36[/tex]

Hence, the total number of yellow pieces is 36

Final answer:

To find the total number of yellow game pieces in the container, we can use the given probabilities to calculate the number of yellow pieces. By setting up equations based on the information provided, we determine that there are 8 yellow game pieces in the container.

Explanation:

Let's first calculate the total number of game pieces in the container.

Let x be the total number of yellow game pieces. The total number of game pieces is 80.

Given that the probability of choosing a green piece is 0.2 and the probability of choosing a yellow piece is 0.45:

Let the number of green pieces be (80 - x), so 0.2(80 - x) = 4 - 0.2x

Now, we know the number of yellow pieces is x, so 0.45x = 0.45x

Solving the equations, we get x = 8, thus there are 8 yellow game pieces in the container.

Answer:

Headband: 15.98 in.

Wristband: 8.63 in.

Step-by-step explanation:

In this problem, we call:

h = the amount of fabric used for each headband

w = the amount of fabric used for each wristband

We are told that:

Sean uses 671.16 in at on headbands for 39 players and three coaches, so the total number of headbands made is 42

Therefore, we can write

[tex]671.16 = 42 h[/tex]

And solving for h, we find

[tex]h=\frac{671.16}{42}=15.98 in.[/tex]

Then we also know that Sean uses 336.57 in the fabric on wristbands just for the players, so he produced 39 wristbands; so we can write:

[tex]336.57 = 39w[/tex]

And solving for w,

[tex]w=\frac{336.57}{39}=8.63 in.[/tex]

Answer:

An apple costs $2.25. A mango costs $1.25.

Step-by-step explanation:

Let a = price of 1 apple.

Let m = price of 1 mango.

Cameron:

4 apples + 7 mangoes ----> total $17.75

4a + 7m = 17.75

Gavin:

2 apples + 5 mangoes ----> total $10.75

2a + 5m = 10.75

We have a system of 2 equations in 2 unknowns.

4a + 7m = 17.75

2a + 5m = 10.75

We can use the elimination method to eliminate the variable a. Rewrite the first equation. Multiply both sides of the second equation by -2 and write below it. Then add the equations.

           4a + 7m = 17.75

(+)       -4a - 10m = -21.5

---------------------------------

                    -3m = -3.75

Divide both sides by -3.

m = 1.25

A mango costs $1.25.

Now we use the first equation and substitute 1.25 for m and solve for a.

4a + 7m = 17.75

4a + 7(1.25) = 17.75

4a + 8.75 = 17.75

4a = 9

a = 2.25

An apple costs $2.25.

Answer: An apple costs $2.25. A mango costs $1.25.

Answer:

2.25 ; 1.25

Step-by-step explanation:

4A + 7M = 17.75

2A + 5M = 10.75

2A = 10.75 - 5M

4A = 21.5 - 10M

21.5 - 10M + 7M = 17.75

3.75 = 3M

M = 1.25

4A = 21.5 - 10(1.25)

4A = 9

A = 2.25

62 units is the answers

Step-by-step explanation:

The correct answer is C) 68 units². The net to compute the surface area of the three-dimensional figure is C) 68 units².

To compute the surface area of a three-dimensional figure, one must consider all the faces that make up the shape. The net of a three-dimensional figure provides a two-dimensional representation of all these faces. By calculating the area of each face and summing them up, we can find the total surface area.

Let's assume the net provided shows a figure composed of rectangles and triangles. We will calculate the area of each face as follows:

1. For rectangles, the area is given by the formula A = length × width.

2. For triangles, the area is given by the formula A = 1/2  × base × height.

Let's denote the lengths of the sides of the rectangles as l and w, and the base and height of the triangles as b and h, respectively.

Now, let's calculate the area of each face:

- Rectangle 1: A1 = l ×  w

- Rectangle 2: A2 = l ×  w (assuming it has the same dimensions as Rectangle 1)

- Triangle 1: A3 = 1/2 × b × h

- Triangle 2: A4 = 1/2 ×  b ×  h (assuming it has the same dimensions as Triangle 1)

The total surface area (SA) is the sum of the areas of all faces:

SA = A1 + A2 + A3 + A4

SA = (l × w) + (l ×  w) + (1/2 × b ×  h) + (1/2×  b ×  h)

SA = 2lw + bh

SA= 2*5*3+19*2

SA=68

After performing these calculations with the given measurements from the net, we would find that the total surface area is 68 units².

Therefore, the correct answer is C) 68 units²."

Maximum width of image that can be viewed clearly on the cylindrical screen is 10 ft

Step-by-step explanation:

Here we have

Circumference of screen = 2πr = 120 ft

Angle that can be viewed horizontally either side of focus = 15°

Total angle view = 30°

Size of image that can be viewed = Object within 30° of focus

Maximum width of image that can be viewed clearly = Perimeter of 30° arc section of cylinder

Maximum width of image that can be viewed clearly = 30/360×120 ft = 10 ft.

Answer: b & c

I got the answer right on my quiz

The following statements are true:

- To begin converting the equation to standard form, subtract 36 from both sides.

- To complete the square for the x terms, add 4 to both sides.

- The center of the circle is at (-2, 3).

- The radius of the circle is 7 units.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

To convert the equation to standard form, we need to complete the square for both the x and y terms.

x² + y² + 4x - 6y - 36 = 0

x² + 4x + y² - 6y = 36

(x² + 4x + 4) + (y² - 6y + 9) = 49

(x + 2)² + (y - 3)² = 7²

So the center of the circle is at (-2, 3) and the radius of the circle is 7 units.

Therefore, the following statements are true:

- To begin converting the equation to standard form, subtract 36 from both sides.

- To complete the square for the x terms, add 4 to both sides.

- The center of the circle is at (-2, 3).

- The radius of the circle is 7 units.

And,

The statement "The center of the circle is at (4.-6)" is false, and the statement "The radius of the circle is 49 units" is also false.

Thus,

The following statements are true:

- To begin converting the equation to standard form, subtract 36 from both sides.

- To complete the square for the x terms, add 4 to both sides.

- The center of the circle is at (-2, 3).

- The radius of the circle is 7 units.

Answer:

5.83 or E

Step-by-step explanation:

Use Pythagorean theorem. 5^2+3^2=c^2 because the diameter is perpendicular it cuts the chord in half.

25+9=c^2  

34=c^2

5.83

Answer:

x = 5.83.

Step-by-step explanation:

The diameter bisects the vertical chord so the right triangle has legs 3 and 5.

So x^2 = 3^2 + 5^2

x^2 = 34

x = 5.83.

That is odd - if we work it out another way we get a different answer. I guess that must be because the numbers given in the diagram are not possible.

If we use the intersecting chords theorem,  we get (3+6)*3 = 27

= 5 * y where y is the other leg of the right triangle giving y = 5.4

and then this will give x = 6.18.
