Answer:

Step-by-step explanation:

By using remainder theorem , value of P(1) = (-1)

P(1) = 1 + 3 + 4 - 9

P(1) = (-1)

Remainder Theorem is an approach of Euclidean division of polynomials. According to this theorem, if we divide a polynomial P(x) by a factor ( x – a); that isn’t essentially an element of the polynomial; you will find a smaller polynomial along with a remainder. This remainder that has been obtained is actually a value of P(x) at x = a, specifically P(a)

For finding the value of P(1) we have to put the value of 1 on the place of x, then we can get  P(1) = (-1)

The Population Changes table indicate the following percent of change of the three towns

Question 1: The percent of change for Centerville is about 29.6%

Question 2: The town with the greatest percent of change is Riverview

Question 3: The percent of change for Riverview is about 51%

A percent of change is the change in the value of a parameter, expressed as a percentage.

Question 1: The population Centerville in 2000 = 37,065

The population of Centerville in 2010 = 26,102

The percentage change can be found using the formula;

[tex]Percentage \ change=\dfrac{New \ value - Initial \ value}{Initial\ value} \times 100[/tex]

The percentage change for Centerville is therefore;

[tex]Percentage \ change=\dfrac{Population \ in \ 2010-Polulation \ in \ 2000}{Population \ in \ 2000} \times 100[/tex]

From which we get;

[tex]Percentage \ change \ for \ Centerville=\dfrac{26102-37065}{37065} \times 100 \approx -29.6\%[/tex]

Question 2:

The percent of change for the town of Lakeside is found as follows;

Percentage change = ((45,863 - 51,342)/(51,342)) × 100 ≈ -10.7%

The percent of change of the population of Riverview is found using the percentage change formula as follows;

Percentage change = ((63017 - 41726)/(41726)) × 100 = 51%

Therefore, the town that had the greatest percent of change is is Riverview

Question 3: The percent of change for Riverview is about 51%

Answer: 45

(Read the explanation to make sure it is correct)

Step-by-step explanation:

Let's start with what we know. Since the sum of all angles in a triangle add up to 180, we can use that logic to find the last angle in the triangle. So far, we have:

85 + 50 + x = 180

We subtract 135 from both sides to get:

Answer: Using proportions, it is found that of the remaining pins, 14 pins are green and 21 pins are yellow.

A proportion is a fraction of a total amount, and then operations such as multiplication are applied to find the equivalent amounts relative to the proportion.

In this problem, we have that:

3/7 of the x pins are green.

4/7 of the x pins are yellow.

With one less pin, 2/5 are green and 3/5 are yellow, hence:

3/7x - 1 = 2/5x.

Isolating for x and applying the least common multiple, we have that:

x = 35.

He has 35 pins remaining, hence:

2/5 x 35 = 14 pins are green.

3/5 x 35 = 21 pins are yellow.

What is the missing information?

A. The meters that Gianna walk each hour is 5760 meters.

B. The kilometers that Gianna walk each hour is 5.760 kilometers.

The distance can be found by illustrating it as an expression. Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

There are 1000 meters in 1 kilometer

3600 seconds = 1 hour

Gianna's average walking rate is 1.6 meters per second. The distance in an hour will be:

= 1.6 × 3600

Answer:

To solve this problem, we first need to find out how much time it will take for the airplane that is descending to reach the same altitude as the airplane that is ascending. To do this, we can use the formula d = r * t, where d is the distance, r is the rate, and t is the time.

In this case, the distance is the difference between the starting altitudes of the two airplanes, which is 42,000 feet for the descending airplane and 0 feet for the ascending airplane. The rate is the rate at which the descending airplane is descending, which is 3,500 feet per minute. Plugging these values into the formula, we get:

d = r * t

d = (3,500 feet/minute) * t

d = 42,000 feet

Solving for t, we get:

t = d / r

t = (42,000 feet) / (3,500 feet/minute)

t = 12 minutes

So it will take 12 minutes for the descending airplane to reach the same altitude as the ascending airplane.

To find the altitude at which the two airplanes will be at the same altitude, we can use the formula d = r * t, where d is the distance, r is the rate, and t is the time. In this case, the distance is the altitude at which the two airplanes will be at the same altitude, the rate is the rate at which the ascending airplane is ascending, which is 2,500 feet per minute, and the time is the time it will take for the descending airplane to reach the same altitude as the ascending airplane, which we calculated to be 12 minutes.

Plugging these values into the formula, we get:

d = r * t

d = (2,500 feet/minute) * (12 minutes)

d = 30,000 feet

Therefore, the altitude at which the two airplanes will be at the same altitude is 30,000 feet.

There are several other ways we could have solved this problem. For example, we could have used the formula d = r * t to find the altitude of the ascending airplane at the same time that the descending airplane reaches the same altitude, and then subtracted the starting altitude of the ascending airplane (0 feet) from this value to find the altitude at which the two airplanes will be at the same altitude.

Another way to solve this problem is to use the formula d = (v1 + v2) * t / 2, where d is the distance, v1 and v2 are the rates at which the two airplanes are moving, and t is the time. In this case, we can set d equal to the difference between the starting altitudes of the two airplanes, v1 equal to the rate at which the descending airplane is descending, v2 equal to the rate at which the ascending airplane is ascending, and t equal to the time it will take for the descending airplane to reach the same altitude as the ascending airplane.

Plugging these values into the formula, we get:

d = (v1 + v2) * t / 2

d = (3,500 feet/minute + 2,500 feet/minute) * (12 minutes) / 2

d = (6,000 feet/minute) * (12 minutes) / 2

d = (72,000 feet) / 2

d = 36,000 feet

Therefore, the altitude at which the two airplanes will be at the same altitude is 36,000 feet.

We can also solve this problem using a table to track the altitude of the two airplanes over time. We can start by making a table with

what is uniform probability with three examples?

Uniform probability is a type of probability distribution in which all outcomes have the same probability of occurring. This means that all outcomes have an equal chance of being selected, and no one outcome is more likely to occur than any other. For example, if you were to roll a die, each of the six outcomes (1, 2, 3, 4, 5, 6) would have an equal probability of occurring. Here are three examples of uniform probability:

1. Tossing a coin: When a coin is tossed, the probability of it landing on either heads or tails is 50%. This is because both outcomes have an equal chance of occurring, making it a uniform probability.

2. Rolling a dice: When a dice is rolled, the probability of it landing on any of the six numbers (1, 2, 3, 4, 5, 6) is equal, at 16.67%. This is because all outcomes have an equal chance of occurring, making it a uniform probability.

3. Drawing a card from a deck: When a card is drawn from a deck, the probability of it being any of the 52 cards (13 of each suit) is equal, at 1.92%. This is because all outcomes have an equal chance of occurring, making it a uniform probability.

Step-by-step explanation: I had this same question before

5 miles is the distance a cyclist travels in 20 minutes, then 0.25 miles does the cyclist travel in 1 minutes.

A mile was equivalent to 1,000 Roman strides, with a stride being equal to two paces. The term "mile" is derived from the Latin "mille passus," which means "one thousand paces." The English Parliament established the Mile at eight furlongs (one furlong is 660 feet) in 1592. 5,280 feet, 1,760 yards, or around 1,609 meters make up a mile. On July 1, 1959, an international agreement established the mile's precise measurement at 1609.344 metres. Currently, the mile is the only unit of measurement used in the US and UK.

So, a mile is one of many different distance units.

Given that,

In 20 minutes a cyclist travels distance of 5 miles

So, in 1 minutes cyclist travels distance of [(5/20) × 1] miles
