It would take an echo sounder's ping 88 seconds to make the trip from a ship to the Challenger Deep (10,994 meters) and back. The speed of sound in seawater is 1,500 meters per second, which is used to calculate the round-trip time of the ping.

Given, The depth of Challenger Deep, d = 10,994 meters.

The speed of sound in seawater = 1500 meters per second. Assuming the sound moves at a constant speed, we can calculate the time it takes for a sound to travel 1 meter as follows:

t = d/s, where t = time taken to travel 1 meter, d = distance traveled by sound (in meters), s = speed of sound in seawater (in meters/second)

Substituting the values, we get

t = 10,994/1500 = 7.33 seconds

To find the round-trip time of the ping, we need to double this time, so the total time taken by the ping is 2 × 7.33 = 14.66 seconds. However, the ping travels from the ship to the Challenger Deep and then back to the ship. So, we need to double the time taken by the ping again to account for the return trip. Therefore, the round-trip time of the ping is

=2 × 14.66 = 29.32 seconds. Finally, converting the time into seconds, we get 88 seconds.

Hence, it would take an echo sounder's ping 88 seconds to make the trip from a ship to the Challenger Deep (10,994 meters) and back.

\(\boxed{\textsf{ The first negative term of the sequence is \textbf{-4} .}}\)

Step-by-step explanation:

A sequence is given to us . And we need to find the first negative term of the sequence. So the given sequence to us is :-

\(\sf\implies Sequence = 31 , 26 , 21 , 16 ..... \)

Here first term of the sequence is 31. And the common difference is 26 - 31 = -5 . Hence here (-5) is added to each number to obtain the second number of the sequence .

Here the last term mentioned is 16. And we are subsequently adding (-5) to each term to obtain the next term . Next third term will be obtained after adding 5×(-3) = -15 .

And that term will be , 16 - 15 = 1 .

Hence the last positive term is 1 . The next term term after adding (-5) will be the first negative term.

\(\sf \implies 1st \ negative \ term = 1 -5 =\pink{-4} . \)

What is combination?

A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The quantity of k-combinations for a set with n components

Sample: Kevin should have used an open circle on 1, not a closed circle. The closed circle means that 1 is included in the solution set, but the inequality is x > 1, so 1 is not part of the solution.

Mistake done by Kelvin is he  used closed circle at 1 where inequality x > 1 which excludes 1.

" Closed circle represents that the value is included in the given range while that of open circle represents given number is not included."

According to the question,

Graph of inequality x > 1 represents all values greater 1 excluding 1.

Number line represents -3 to 5.

A closed circle at 1 means 1 is included.

As per the condition  of inequality x > 1 , 1 is excluded while in closed circle 1 is included both are contradictory conditions.

Explicación paso a paso:

Podemos obtener la altura de la torre de enfriamiento usando trigonometría;

Tan θ = opuesto / adyacente

Altura de la torre de enfriamiento = opuesto

Altura de la sombra = 271 m = adyacente

Tan 30 = opuesto / 271

Opuesto = 271 tan30

Altura de la torre de enfriamiento = 0.5773502 * 271

Altura de la torre de enfriamiento = 156,46 m

To solve this system of equations, we can use the method of elimination. The goal is to eliminate one of the variables, such as x or y, by adding or subtracting the equations.

First we can eliminate the y variable by adding the two equations together:

X + 3y = 14

2x - 3y = -8

3x = 6

Dividing both sides by 3:

x = 2

Now we have the value of x, we can substitute it back into one of the original equations:

X+3y=14

2 + 3y = 14

Subtracting 2 from both sides:

3y = 12

Dividing both sides by 3:

y = 4

So the solution of the system of equations is (x,y) = (2,4)

To check the solution, we can substitute the values back into the original equations:

x + 3y = 14

2 + 3(4) = 14

2 + 12 = 14

14 = 14

and

2x - 3y = -8

2(2) - 3(4) = -8

4 - 12 = -8

-8 = -8

As the equation holds true, the solution (2,4) is correct.

Answer:

x = 21

y = 114

Step-by-step explanation:

Here, we are to find the values of x and y

Mathematically;

3x - 15 + 6x + 6 = 180

reason for this is that opposite interior angles are supplementary, they add up to 180

9x-9 = 180

9x = 180 + 9

9x = 189

x = 189/9

x = 21

Also;

3x-15 + y + 18 = 180

Reason for this is that angles on a straight line are supplementary

Recall, x = 21

3(21)-15 + y + 18 = 180

63-15 + y + 18 = 180

y = 180-66

y = 114 degrees

The scale that a person can use for the vertical axis such that the difference in the heights of the bars is maximized is called Logarithmic Scale.

Logarithmic Scale: It is used when the data covers a large range of values, as it allows for a more precise representation of the data.

It compresses the data so that the graph can fit on a single page.

The logarithmic scale has a logarithmic base, which is often 10 or e.

The tick marks and labels on a logarithmic scale aren't evenly distributed; instead, they're spaced according to the logarithm of their values.

The logarithmic scale, also known as the log scale, is a scale that measures values logarithmically rather than linearly.

A logarithmic scale is commonly used in scientific and engineering graphs and charts. It is used for data that covers a large range of values, such as population growth, global warming, and the stock market.

A ternary string is a string composed of characters 0, 1, and 2. The number of ternary strings that contain exactly n characters, each of which is one of three types, is 3^n.Exactly 5 0s, 5 1s, and 5 2s are required for the ternary string, which means that the total number of characters is 15.

Each of these characters can be one of three types (0, 1, or 2). As a result, the total number of possible strings is 3^15. This is equivalent to 14,348,907. We arrived at this conclusion by computing 3 to the fifteenth power.Explanation:When constructing a sequence of three symbols, the first symbol has three alternatives, the second symbol has three alternatives, and so on. There are n choices for each of the n characters, resulting in a total of 3^n possible sequences.Example 1:Let's assume we have to create 5-character sequences with three symbols: a, b, and c. There are 3*3*3*3*3 = 243 possible sequences since there are three choices for each symbol.Example 2:Let's assume we have to construct a 10-character sequence using three symbols: 0, 1, and 2. There are 3*3*3*3*3*3*3*3*3*3 = 59,049, a total of 59,049 possible 10-character sequences. We can perform the same calculation for 15-character strings using the same logic.

Step-by-step explanation:

The figure is composed of 3 rectangles.

A( lower) = 5 × 7 = 35 in²

A(middle) = 10 × 6 = 60 in²

A(right) = 6 × 9 = 54 in²

Sum the 3 areas for total area

Total area = 35 + 60 + 54 = 149 in²

Answer:

149 inches square.

Step-by-step explanation:

Given,

length (l) = 7 in.

breadth (b) = 5 in.

Area (A1) = l×b

= 7×5

= 35 inches square

now,

length = 9 in.

breadth= 6 in.

Area (A2) = l×b

= 9×6

= 54 square inches

again,

length = 10 in.

breadth = 6 in.

Area (A3) = l×b

= 10×6

= 60 square inches

Area of irregular figure = A1+ A2+ A3

= 35 +54 + 60

A function that is the same type as W(x) is B(x) because it shows a common ratio among the data points.

In Mathematics and Geometry, an exponential function can be modeled by using this mathematical equation:

\(f(x) = a(b)^x\)

Where:

Based on the graph, we can logically deduce that W(x) is an exponential equation with the following common ratio;

Common ratio, r = a₂/a₁

Common ratio, r = 48/24 = 96/48 = 192/96

Common ratio, r = 2.

For B(x), we have:

Common ratio, r = 6/2 = 18/6 = 54/18

Common ratio, r = 3.

Therefore, B(x) is the same as W(x).

For M(x), we have:

Common ratio, r = 120/20 = 420/120 = 920/420

Common ratio, r = 60 ≠ 3.5 ≠ 2.19.

Therefore, M(x) is not the same as W(x).

For S(x), we have:

Common ratio, r = 81/38 ≠ 124/81 ≠ 167/124.

It will take approximately 7.27 years for your mother's investment to become worth $1,000,000 when invested in a well-diversified, low-cost mutual fund returning 10% per year.

To determine the number of years it will take for your mother's investment to become worth $1,000,000, we can use the future value formula:

FV = PV * (1 + r)^n

Where:

FV = Future value ($1,000,000)

PV = Present value ($500,000)

r = Annual interest rate (10% or 0.10)

n = Number of years (unknown)

Substituting the given values into the formula:

$1,000,000 = $500,000 * (1 + 0.10)^n

Simplifying the equation:

2 = (1.10)^n

Taking the logarithm of both sides:

log(2) = log(1.10)^n

Using the logarithmic property:

log(2) = n * log(1.10)

Solving for n:

n = log(2) / log(1.10)

Using a calculator:

n ≈ 7.27

Therefore, it will take approximately 7.27 years for your mother's investment to become worth $1,000,000 when invested in a well-diversified, low-cost mutual fund returning 10% per year.
