Answer:

Step-by-step explanation:

f⁻¹(x) is the inverse of f(x).

y = 4x − 9.  To find the inverse, switch x and y and solve for y.

x = 4y − 9

x + 9 = 4y

y = (x + 9) / 4

So the inverse function is:

f⁻¹(x) = (x + 9) / 4

ANSWER

[tex]{f}^{ - 1}(x) = \frac{x + 9}{4} [/tex]

EXPLANATION

The given function is

f(x)=4x-9

Let

y=4x-9

Interchange x and y.

x=4y-9

Add 9 to both sides,

x+9=4y

Divide both sides by 4

[tex] \frac{x + 9}{4} = y[/tex]

[tex]y = \frac{x + 9}{4} [/tex]

Therefore,

[tex] {f}^{ - 1}(x) = \frac{x + 9}{4} [/tex]

Answer: (-2, 5) Quadrant II

Step-by-step explanation:

For every point in the plane, we will identify the location using an ordered pair of the form (x, y).

The first coordinate, the x-coordinate, will refer to the number which corresponds with the point's horizontal location as determined by the number on the x-axis.

The second coordinate, the y-coordinate, will refer to the number which corresponds with the point's vertical location as determined by the number on the y-axis.

Quadrant II: x-coordinate is negative and y-coordinate is positive.

[tex]\textit{\textbf{Spymore}}[/tex]​​​​​​

The point (-2, 5) is located in the second quadrant.

A quadrant is a region defined by the two axes (x-axis and y-axis) of the coordinate system.

Given the location of Point A at (-2, 5):

This implies that x = -3 and y = 5 represent the coordinates of Point A. In reference to the Coordinate Plane:

Since the coordinates of point A is (-2, 5), this matches the description of the points located in Quadrant II.

Therefore, the point (-2, 5) is located in the second quadrant.

Probability that the next customer to enter Jeremy's Pet Store has exactly 3 pets is 0.23.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that a dot plot shows how many pets each customer owned before entering Jeremy's Pet Store today.

Based on this data we need to find the reasonable estimate of the probability that the next customer to enter Jeremy's Pet Store has exactly 3 pets.

The total number of customer enter  Jeremy's Pet Store is 13.

Probability that the next customer to enter Jeremy's Pet Store has exactly 3 pets= 3/13

Total Weight of sand =90Kg

Ratio in which sand is divided= 2:3:7

Let x be the fundamental unit in which the sand is divided.

By conservation of mass.

2x +3x + 7x= 90

=> 12x =90

=> x=90/12 =45/6=15/2=7.5

So Amount of sand in small bag=2×7.5=15Kg

Amount of sand in medium bag =3×(7.5)=23.5Kg

Amount of sand in Large bag =7×(7.5)=52.5 Kg

Hope it helps...

Regards;

Leukonov/Olegion.

Add the ratios to find the total shares:

2 + 3 +7 = 12

Divide the total weight by the number of shares:

90 kg/ 12 =7.5 kg per share.

Now multiple each share by the weight per share:

Small = 2 x 7.5 = 15 kg

Medium = 3 x 7.5 = 22.5 kg

Large = 7 x 7.5 = 52.5 kg

Answer:

≈ 12.43 ( to 2 dec. places )

Step-by-step explanation:

Given

tan46° = [tex]\frac{x}{12}[/tex]

Multiply both sides by 12

12 × tan46° = x, so

x ≈ 12.43

The value of x is 12.426 in the equation Tan 46° = x/12

Tan 46° represents the ratio of the opposite side to the adjacent side in a right triangle with a 46° angle.

Using the tangent function, we have:

Tan 46° = x/12

To find the value of x, we can multiply both sides of the equation by 12:

12 ×Tan 46° = x

Now, we can calculate the value of x using the tangent of 46°:

x = 12×Tan 46°

x=  12 × 1.03553031374

x = 12.4263637649

Therefore, the value of x is 12.426

3:4 is the ratio there are more soda cans

Step-by-step explanation:

There are more sodas than candy bars. Specifically, there are 4 sodas and 3 candy bars, which means there is 1 more soda than candy bars.

To compare the number of sodas to candy bars, we simply look at the quantities given. We have 4 sodas and 3 candy bars. To determine which quantity is greater, we can subtract the number of candy bars from the number of sodas:

Number of sodas - Number of candy bars = 4 - 3 = 1

Since the result is a positive number, it indicates that there are more sodas than candy bars. In this case, there is exactly 1 more soda than candy bars. Therefore, we can conclude that the number of sodas is greater than the number of candy bars.

June and Stella can together create 12 floral arrangements per hour. To fulfill 372 orders, they would need to work for 31 hours.

This problem is solved by calculating the combined rate of work of June and Stella and then using this to calculate the time it will take to complete the orders. June and Stella can create a total of 12 floral arrangements per hour (6 arrangements each). Therefore, to complete 372 orders, they would need 372 divided by 12 hours.

To perform this calculation, divide 372 by 12:

372 ÷ 12 = 31 hours

So, June and Stella would need 31 hours to complete 372 Valentine’s Day floral arrangements if they work together at their current rate.

June and Stella will need 31 hours to fulfill the 372 Valentine's Day orders.

To find out how many hours June and Stella will need to fulfill the orders, we can use the concept of unit rates. We know that June and Stella each create 6 floral arrangements in 1 hour. So together, they can create 12 floral arrangements in 1 hour. Now, we can set up a proportion using the given information: 1 hour is to 12 floral arrangements as x hours is to 372 floral arrangements. This can be written as: 1/12 = x/372. To solve for x, we can cross-multiply: 12x = 372. Dividing both sides by 12 gives us x = 31. Therefore, June and Stella will need 31 hours to fulfill the 372 orders.

The cube of a number (n) divided by two can be mathematically represented as n³/2.

The cube of a number is achieved when you raise that number to the power of 3. If we have a number, let's denote it as 'n', and we cube it, and we get n³. Now, if you are to divide the cube of a number by two, the formula would be n³/2. For example, if n = 2, the cube of 2 is 8, divided by two equals 4.

The cube of a number divided by two means that you take a number raise it to the power of 3, and then divide the result by 2. For example, if the number is 4, the cube of 4 is 4 × 4 × 4 = 64. Dividing 64 by 2 gives you a result of 32.

Answer:

The correlation coefficient is 0 which implies no association between the number of apples eaten per week and the times sick in a year.

Step-by-step explanation:

The correlation coefficient between paired data gives information on the strength and the direction of the relationship between the paired data sets. The coefficient of correlation can imply strong or weak association as well as positive or negative association between data sets.

In the data given, the number of apples eaten per week can be used to explain the number of times an individual falls ill per year. This implies that the number of apples eaten per week is our explanatory or independent variable while times sick in a year is our response or dependent variable.

We can use Ms.Excel to compute the correlation coefficient between these two variables;

The first step is to enter the data in two adjacent columns in an excel workbook. We then type;

=CORREL

In an empty cell and enter the data arrays. This is an in-built function that computes the correlation coefficient.

Ms. Excel returns a correlation coefficient of 0. The correlation coefficient of 0 implies no association between the number of apples eaten per week and the times sick in a year.

x = - 3, x = 2

Step-by-step explanation:

Given

x² + x - 6 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)

The factors are + 3 and - 2, since

3 × - 2 = - 6 and 3 - 2 = + 1, hence

(x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2
