The depth of the water is 5.3 meters

The dolphin jumps to a height of 4.5 over the water's surface, and her companion swims 9.8 straight beneath her, according to the story.

We will take the position of the dolphin's friend and subtract it from the dolphin's position to determine the location of the dolphin's friend with respect to the water's surface.

-5.3 denotes the depth of the water.

As a result, the friend of the dolphin is located 5.3 meters below the water's surface.

Answer: The square root of 169 is 13, so the two solutions for x are:

x = (13 + 13) / 4 = 3.25

x = (13 - 13) / 4 = -0.25

Since the quadratic expression 2x^2 - 13x - 5 equals 0 when x is either 3.25 or -0.25, the factors of this expression are (x - 3.25)(x + 0.25).

In summary, the factors of the first quadratic expression are (x + 1.056)(x + 5.937), the factors of the second expression are (x - 0.75)(x + 3.75), and the factors of the third expression are (x - 3.25)(x + 0.25).

Step-by-step explanation: To find the factors of a quadratic expression, we can use the quadratic formula. The quadratic formula states that for a quadratic expression of the form ax^2 + bx + c = 0, the solutions for x are given by the formula x = (-b ± sqrt(b^2 - 4ac)) / (2a).

In the first equation, a is 9, b is 31, and c is 20. Plugging these values into the quadratic formula, we get:

x = (-31 ± sqrt(31^2 - 4 * 9 * 20)) / (2 * 9)

This simplifies to:

x = (-31 ± sqrt(961 - 720)) / 18

This further simplifies to:

x = (-31 ± sqrt(241)) / 18

We can find the value of the square root by using a calculator or by remembering some common square roots. The square root of 241 is approximately 15.937, so the two solutions for x are:

x = (-31 + 15.937) / 18 = -1.056

x = (-31 - 15.937) / 18 = -5.937

Since the quadratic expression 9x^2 + 31x + 20 equals 0 when x is either -1.056 or -5.937, the factors of this expression are (x + 1.056)(x + 5.937).

We can use the same approach to find the factors of the other two quadratic expressions. For the second expression 2x^2 + 7x - 4, the values of a, b, and c are 2, 7, and -4, respectively. Plugging these values into the quadratic formula, we get:

x = (-7 ± sqrt(7^2 - 4 * 2 * -4)) / (2 * 2)

This simplifies to:

x = (-7 ± sqrt(49 + 32)) / 4

This further simplifies to:

x = (-7 ± sqrt(81)) / 4

The square root of 81 is 9, so the two solutions for x are:

x = (-7 + 9) / 4 = 0.75

x = (-7 - 9) / 4 = -3.75

Since the quadratic expression 2x^2 + 7x - 4 equals 0 when x is either 0.75 or -3.75, the factors of this expression are (x - 0.75)(x + 3.75).

For the third expression 2x^2 - 13x - 5, the values of a, b, and c are 2, -13, and -5, respectively. Plugging these values into the quadratic formula, we get:

x = (13 ± sqrt(13^2 - 4 * 2 * -5)) / (2 * 2)

This simplifies to:

x = (13 ± sqrt(169 + 40)) / 4

The value of the equation log(3 47) is about 4.235.

The power to which a number must be increased in order to obtain another number is known as a logarithm. For instance, since ten raised to the power of two equals 100, the base ten logarithm of 100 is 2: log 100 = 2.

Given that the approximate values of log(3) and log(47) are 1.1 and 3.85, respectively,

we must determine the approximate value of log(347).

log(a × b) = log(a) × log(b)

we get ,

log(3 × 47) = log(3) × log(47)

substituting , the values of log(3) and log(47) ,

we get ,

log(3 × 47) = 1.1 × 3.85

≈ 4.235

Therefore , The approximate value of log(3 × 47) is 4.235   .

A graph of the given system of equations f(x) = 2x² - 8x + 3 and g(x) = -2x + 3 is shown in the image attached below.

The points that make both equations true is (0, 3)

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate respectively.

In Mathematics, the graph of every quadratic equations (functions) is either an upward or downward parabola, which is typically a u-shaped curve. This ultimately implies that, the graph of a quadratic equation (function) would always form a parabolic curve.

Based on the graph (see attachment), we can logically deduce that the solution to the given system of equations is the point of intersection of the lines on the graph representing each, which is the ordered pair (0, 3);

f(x) = 2x² - 8x + 3

3 = 2(0)² - 8(0) + 3

3 = 3 (True).

g(x) = -2x + 3

3 = -2(0) + 3

3 = 3 (True).

On solving the provided question, we got that The 90% confidence interval for the population mean mu is (140.4, 147.6)

A measure of how far the data are from the mean is called standard deviation (or). Data that have a low standard deviation are more likely to be centered around the mean than those that have a high standard deviation.

xbar = 144 (sample mean)

s = 12 (sample standard deviation)

n = 30 (sample size)

z = 1.645 (critical value at 90% confidence; use a calculator or table to compute this value)

[tex]The lower limit of the confidence interval is L, which is found by\\\\L = xbar - z(s/sqrt(n))\\L = 144 - 1.645(12/sqrt(30))\\L = 140.395985571616\\L = 140.4\\[/tex]

Similarly the upper limit U is

U = xbar + z(s/sqrt(n))

U = 144 + 1.645(12/sqrt(30))

It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. A phrase in language may contain an action on its own, but it does not constitute a whole sentence.

Lela is making peach pies. She uses 9 peaches for each pie. If she uses 18 peaches for 2 pies and 36 peaches for 4 pies, how many peaches will she need for 7 pies?

As, Lela is using 9 peaches for each pie.

Thus, she used 18 peaches for 2 pies, which is 2 times 9 and 36 peaches for 4 pies, which is 4 times 9. Therefore, to make 7 pies, she would need :

Peaches used for one pie = 9

=> Peaches used for 7 pies = 9 × 7

=> Peaches needed for 7 pies = 63

Hence, she will need 63 peaches to make 7 pies.

The height of the flagpole, found using the ratio of the sides of similar triangles is 12.975 meters

Similar triangles are triangles  in which two angles of one triangle  are congruent to two angles in the other triangle, such that they have the same shape.

The parameters that can be used to find the height of the flagpole are;

Distance of the mirror from the flagpole = 8.65 meters

Distance of Feng on the other side of the flagpole = 1.1 meters

The height from Feng's eyes to the ground = 1.65 meters

According to the law of reflection, the angle of incident and the angle of reflection are the same

The angle made by Feng and the ground = Angle made by the flagpole and the ground = 90°

The triangle formed by the Feng and the flagpole are therefore similar by AA similarity postulate

The ratio of corresponding sides of similar triangles are the same, therefore;

[tex]\dfrac{1.65}{Height\, of \, the \, flagpole} = \dfrac{1.1}{8.65}[/tex]

Answer: To estimate the company's sales in 2026, we need to find the average increase in sales per year and then use that to predict the sales for 2026.

The total increase in sales from 2017 to 2020 was $14.5 million - $9 million = $<<14.5-9=5.5>>5.5 million.

The number of years from 2017 to 2020 is 2020 - 2017 = <<2020-2017=3>>3 years.

Therefore, the average increase in sales per year was $5.5 million / 3 years = $<<5.5/3=1.83>>1.83 million/year.

Since the average increase in sales per year was $1.83 million/year, we can estimate the sales in 2026 by adding that amount to the sales for each year from 2020 to 2026. For example, the estimated sales for 2021 would be $14.5 million + $1.83 million = $16.33 million. Similarly, the estimated sales for 2022 would be $16.33 million + $1.83 million = $18.16 million, and so on.

Using this method, we can estimate that the sales for 2026 will be $26.73 million.
