Answer: -27

Step-by-step explanation: Use inductive reasoning to predict the most probable next number in the list.

3, 9, -3, 3, -9, -3, -15, -9, -21, ?

We can start by looking at the differences between consecutive terms in the list:

9 - 3 = 6 -3 - 9 = -12 3 - (-3) = 6 -9 - 3 = -12 -3 - (-9) = 6 -15 - (-3) = -12 -9 - (-15) = 6 -21 - (-9) = -12

Notice that the differences alternate between positive 6 and negative 12. This suggests that the pattern involves adding 6, then subtracting 12, and then adding 6 again. Applying this pattern to the last term in the list (-21), we get:

-21 + 6 = -15 -15 - 12 = -27 -27 + 6 = -21

Therefore, we predict that the most probable next number in the list is -27.

Answer:

A

Step-by-step explanation:

We know that the growth of a linear function will always be constant. So, that eliminates B and C.

A quadratic function can be a function such as \(x^2\), or \(5x^2+7x\), etc.

An exponential function wouldn't be \(x^2\), it would be \(2^x\)! Or \(3^x\), or \((1.738283)^x\), etc. Therefore, D is eliminated.

So, the answer is \(\boxed{A}\) and we're done!

Answer:

495

Step-by-step explanation:

using the definition

n\(C_{r}\) = \(\frac{n!}{r!(n-r)!}\)

where n! = n(n - 1)(n - 2) ... × 3 × 2 × 1

then

12\(C_{4}\)

= \(\frac{12!}{4!(12-4)!}\)

= \(\frac{12!}{4!(8!)}\)

cancel 8! on numerator/ denominator

= \(\frac{12(11)(10)(9)}{4!}\)

= \(\frac{11880}{4(3)(2)(1)}\)

= \(\frac{11880}{24}\)

= 495

Answer

Question 1

Option C is correct.

Runner A and B are tied.

Question 2

Option B is correct.

Runner B is the faster runner in this time period.

Question 3

Option A is correct.

Runner A is the faster runner in this time period.

Explanation

Average speed is distance covered divided by time taken.

Question 1

For the first 9 seconds

Runner A

Distance covered = 120 - 0 = 120 m

Time Taken = 9 - 0 = 9 seconds

Average speed = (120/9) = 13.33 m/s

Runner B

Distance covered = 120 - 0 = 120 m

Time Taken = 9 - 0 = 9 seconds

Average speed = (120/9) = 13.33 m/s

Both runners are tied.

Question 2

For 9 seconds to 20 seconds

Runner A

Distance covered = 168 - 120 = 48 m

Time Taken = 20 - 9 = 11 seconds

Average speed = (48/11) = 4.36 m/s

Runner B

Distance covered = 213 - 120 = 93 m

Time Taken = 20 - 9 = 11 seconds

Average speed = (93/11) = 8.45 m/s

Runner B is the faster runner in this time period.

Question 3

For 20 to 31 seconds

Runner A

Distance covered = 287 - 168 = 119 m

Time Taken = 31 - 20 = 11 seconds

Average speed = (119/11) = 10.82 m/s

Runner B

Distance covered = 287 - 213 = 74 m

Time Taken = 31 - 20 = 11 seconds

Average speed = (74/11) = 6.73 m/s

Runner A is the faster runner in this time period.

Question 4

For 0 to 31 seconds

Runner A

Distance covered = 287 - 0 = 287 m

Time Taken = 31 - 0 = 31 seconds

Average speed = (287/31) = 9.26 m/s

Runner B

Distance covered = 287 - 0 = 287 m

Time Taken = 31 - 0 = 31 seconds

Average speed = (287/31) = 9.26 m/s

Both runners are tied in this time interval.

If they maintain a constant speed the entire way, Michelle and Temba would have covered 140 km in 1 hour and 24 minutes.

The following equation can be used to determine the average speed of Michelle and Temba:

Distance x time speed

They covered 30 kilometers in 18 minutes, so their average speed is:

speed = 30 / (18 / 60) = 30 / 0.3, or 100 km/hr.

They would have traveled the following distance in 1 hour and 24 minutes, or in 1 hour + (24 / 60) hours, or 1.4 hours:

The distance= speed × time, or 100 × 1.4 = 140 km.

Therefore, it is important to remember that their speed and the actual distance they travel can be impacted by real-world variables like traffic, road conditions, and vehicle maintenance.

Answer:

First of all: Heat energy is transferred from higher to lower level.

Normally,a room temperature is about 25°C–27°C. Hot food has temperature higher than that, and (cold) drinks have temperature lower than that. So, heat is transferred from/to the atmosphere to maintain heat levels at the Normal temperature and pressure.

When kept in open, heat transfers from the food (higher level of heat) to atmosphere (lower level), decreasing it's temperature, i.e., making it cold.

Likewise, in case of (cold) drinks, heat is transferred to the drink (lower level of heat) from the atmosphere (higher level), hence making it warmer.

Step-by-step explanation:

A rectangle that could have a perimeter of 52 feet is a 12 feet by 14 feet rectangle.

The symbols W and L are variables.

The symbol P is a constant.

In Mathematics and Geometry, the perimeter of a rectangle can be calculated by using this mathematical equation (formula);

P = 2(L + W)

Where:

By substituting the given side lengths into the formula for the perimeter of a rectangle, we have the following;

P = 2(L + W)

52 = 2(12 + 14)

52 = 2(26)

52 feet = 52 feet.

The relationship representing the amount of water remaining in the pool when using the large hose to pump out is

a. 1200 - 60x = y

The amount of water to be pumped out = 1200 gallons

The rate of pumping out using the small hose 20 gallons of water per minute. = -20x

let each minute be x, hence every minute 20x volume of water leaves the pond

The equation is represented as

water remaining = 1200 - 20x

in 2 hours, we have  120 minutes, when will the water finish

water remaining = 0 = 1200 - 20x

20x = 1200

x = 1200 / 20

x = 60 minutes hence 1 hour

For the large hose the rate of pumping out is tripled hence

water remaining = 1200 - 60x

y = 1200 - 60x

The theme is the underlying message, lesson, or central idea conveyed by the narrative or story.

Both a narrative and a story share several common elements that contribute to their structure and presentation. These elements include characters, setting, plot, conflict, and theme.

Characters are essential components of both narratives and stories. They are the individuals or entities that drive the events and experiences within the narrative or story. The setting is the time and place in which the events occur and provide the context for the story.

The plot refers to the sequence of events that unfold and create a structure for the narrative or story. Conflict represents the central problem or challenge faced by the characters and is often a driving force behind the plot's progression.

These shared elements create a framework for both narratives and stories, enabling the development and communication of experiences, ideas, and emotions to the audience. They contribute to the engagement, coherence, and impact of the narrative or story, regardless of the medium or genre in which they are presented.

The maximum revenue possible in this situation is 15625/A dollars, where A is the coefficient in the quadratic equation.

To find the maximum revenue possible in this situation, we can use the concept of vertex or the vertex form of a quadratic equation.

The revenue equation is given by R = -Ax^2 + 250x, where A is a constant coefficient.

The maximum revenue occurs at the vertex of the parabolic curve represented by the equation. The x-coordinate of the vertex can be found using the formula x = -b / (2a), where a and b are the coefficients of the quadratic equation.

In this case, a = -A and b = 250. Plugging in these values, we get:

x = -250 / (2 * (-A))

= 125 / A

To find the maximum revenue, we substitute this value of x into the revenue equation:

R = -A * (125 / A)^2 + 250 * (125 / A)

= -A * (15625 / A^2) + (31250 / A)

= -15625 / A + 31250 / A

= 15625 / A

The maximum revenue is given by 15625 / A. The value of A is not specified in the question, so we cannot determine the exact maximum revenue without knowing the value of A. However, we can say that the maximum revenue increases as A decreases.

Answer:

so first question is b)8/5p=c, explanation in comments and your second question is 25%explanation in comments!! Have a good day and hope this helped!!

Step-by-step explanation:

All the solutions are,

⇒ x = 1/2 (w- v)

⇒ x = (b - 9)/(a - 2)

⇒ x = (4 + w) / (7 - v)

⇒ x = 2 / (v + w)

⇒ x = 7v/(3w - 4)

Given that;

Expressions are,

⇒ 6x + v = 4x + w

⇒ ax + 9 = 2x + b

⇒ 7x - w = vx+4

⇒ 6 - wx = vx + 4

⇒ 3(wx - v) = 4(x + v)

We can simplify as;

⇒ 6x + v = 4x + w

⇒ 6x - 4x = w - v

⇒ 2x = w - v

⇒ x = 1/2 (w- v)

⇒ ax + 9 = 2x + b

⇒ ax - 2x = b - 9

⇒ (a - 2)x = b - 9

⇒ x = (b - 9)/(a - 2)

⇒ 7x - w = vx+4

⇒ 7x - vx = 4 + w

⇒ (7 - v) x = 4 + w

⇒ x = (4 + w) / (7 - v)

⇒ 6 - wx = vx + 4

⇒ vx + wx = 6 - 4

⇒ (v + w)x = 2

⇒ x = 2 / (v + w)

⇒ 3(wx - v) = 4(x + v)

⇒ 3wx - 3v = 4x + 4v

⇒ 3wx - 4x = 7v

⇒ (3w - 4)x = 7v

⇒ x = 7v/(3w - 4)

According to the concept of compound interest, the effective annual yield on your investment of $1800 at a 6.3% interest rate compounded daily is 6.49%.

To find the effective annual yield, we need to use the formula for compound interest:

A = P(1 + r/n)ⁿˣ

Where A is the amount of money at the end of the investment period, P is the principal amount invested, r is the annual interest rate, n is the number of times the interest is compounded in a year, and t is the number of years.

In this case, we know that the principal amount P is $1800, the annual interest rate r is 6.3%, and the interest is compounded daily, which means that n is 365 (the number of days in a year). We need to find the effective annual yield, which is the total amount of interest earned in one year.

To calculate the effective annual yield, we can use the following formula:

Effective Annual Yield = (1 + r/n)ⁿ - 1

Plugging in the values, we get:

Effective Annual Yield = (1 + 0.063/365)³⁶⁵ - 1

Effective Annual Yield = 0.0649 or 6.49%
