What is the acceleration of a bus his speech changes from 126M/S to 3097 m/s over a period of three seconds

Answers

Answer 1

The acceleration of a bus his speech changes from 126M/S to 3097 m/s over a period of three seconds is 990. 3 m/s^2

What is acceleration?

Acceleration is can be defined as the rate of change of the velocity of an object with respect to time.

It is also defined as the rate at which velocity changes with time, that is, in both speed and direction.

Accelerations are vector quantities because they are known to have both magnitude and direction.

The orientation of an object's acceleration is determined by the configuration of the net force acting on that object.

The formula for acceleration is given as;

Acceleration = change in velocity/time

Substitute the values

Acceleration = 3097 - 126 (m/s)/3 s

Divide the values

Acceleration = 990. 3 m/s^2

Find an equation of the line with gradient 4 and that passes through the point
(-5, -5)

Answers

Answer:

y = 4x + 15

Step-by-step explanation:

Using 'y=mx+c' form,

Since m = 4,

y = 4x + c

Substituting (-5, -5) into the above equation:

-5 = -20 + c

c = 15

Hence,

y = 4x + 15

Feel free to mark this as brainliest! :)

Answer:

y = 4x + 15.

Step by step solved:

Using the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the gradient and (x1, y1) is the given point, we can substitute the given values to find the equation:

y - (-5) = 4(x - (-5))

y + 5 = 4(x + 5)

y + 5 = 4x + 20

y = 4x + 15

Therefore, the equation of the line with gradient 4 and passing through the point (-5, -5) is y = 4x + 15.

Answers

The probability that a customer ordered a hot drink, given that they ordered a small, is approximately 0.045.

The Bayes theorem is what?

A mathematical technique called the Bayes theorem enables us to revise our views or probability regarding an occurrence in light of fresh data or evidence. It has the name of the reverend Thomas Bayes, a statistician and philosopher active in the 18th century. According to the Bayes theorem, the likelihood of an event A given that an event B has already happened is equal to the likelihood of an event B given that an event A has already occurred, multiplied by the prior likelihood of an event A, divided by the previous likelihood of an event B.

The Baye's Theorem is given as:

P(B|A) = P(A|B) × P(B) / P(A)

Here,

P(A) is the probability that a customer ordered a small drink = 0.22.

P(B) is the probability that a customer ordered a hot drink, regardless of whether it was small or medium or large = 0.05.

P(A|B) is the probability that a customer ordered a small drink, given that they ordered a hot drink = 0.2.

Substitute the value we have:

P(B|A) = P(A|B) × P(B) / P(A) = (0.2 × 0.05) / 0.22 ≈ 0.045

Therefore, the probability that a customer ordered a hot drink, given that they ordered a small, is approximately 0.045.

The work done by the force as the particle moves from x = 0 m to x = 2.2 m is approximately -0.53 J.

A particle of mass 0.58 kg is subject to a force that is always pointed towards east or west but whose magnitude changes sinusoidally with time. With the positive x-axis pointed towards the east, the x-component of the force is given as follows: fx(t) = (2.6 N) sin(2.2t)where t is in seconds.

The work done by the force as the particle moves from x = 0 m to x = 2.2 m: For a sinusoidal force that changes with time, the work done is given by W = ∫F dx where F is the force, and dx is the displacement. For this problem, the force is given by fx(t) = (2.6 N) sin(2.2t)dx is the displacement, which is given by dx = x2 – x1 where x2 = 2.2 m, and x1 = 0 m.

Substituting for F and dx, we get W = ∫02.2(2.6 sin(2.2t)) dx= 2.6 ∫02.2 sin(2.2t) dx= 2.6 [(-1/2.2) cos(2.2t)]02.2= 1.18 (cos(4.84) – 1)≈ -0.53 J. So, the work done by the force as the particle moves from x = 0 m to x = 2.2 m is approximately -0.53 J.

A family is traveling a total distance of 532 miles. If the family travels at an average speed of 57 miles per hour, which equation represents the number of miles remaining, m, after h hours?

Answers

m = 532 - (57 * h) represents the number of miles remaining after h hours of traveling at an average speed of 57 miles per hour.

The equation m = 532 - (57 * h) is used to represent the number of miles remaining, m, after h hours of traveling at an average speed of 57 miles per hour. The equation works by taking the total distance, 532 miles, and subtracting the product of the average speed, 57 miles per hour, and the amount of hours traveled, h. The result of the equation is the number of miles remaining, m. For example, if the family has been traveling for four hours, the equation would be m = 532 - (57 * 4). Solving the equation, m = 344, meaning the family has 344 miles left to travel. This equation allows the family to easily determine how many miles they have left to travel, given the average speed and amount of time traveled.

Randy claims that he can purchase 3. 5 pounds of chicken salad for $23. 50. Is he correct? Explain.

Answers

Randy's claim is not correct Therefore, he cannot purchase 3.5 pounds of chicken salad for $23.50

To determine if Randy's claim is correct, we can use the given linear graph and points to find the equation of the line that represents the relationship between the amount of chicken salad purchased and the cost.

We can use the two points (1, 7.5) and (3, 22.5) to find the slope of the line:

slope = (change in y) / (change in x)

slope = (22.5 - 7.5) / (3 - 1)

slope = 15 / 2

slope = 7.5

Now we can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept, to find the equation of the line:

y = 7.5x + b

To find b, we can use one of the points on the line, such as (1, 7.5):

7.5 = 7.5(1) + b

b = 0

So the equation of the line is:

y = 7.5x

Now we can use this equation to check if Randy's claim is correct. If he can purchase 3.5 pounds of chicken salad for $23.50, we can plug in x = 3.5 and see if y = 23.5:

y = 7.5x

y = 7.5(3.5)

y = 26.25

Since y = 26.25 is not equal to $23.50

Therefore, Randy's claim is not correct

Answers

The proposed maximum wait time should be 24.2 minutes so that 1% of the customers receive a free meal.

To answer the vice president's request, the proposed maximum wait time should be 24.2 minutes so that 1% of the customers receive a free meal. This can be seen in the graph below, which illustrates the normal distribution of customer wait times with a mean of 20 minutes and a standard deviation of 4 minutes. In this graph, the area of the curve between 0 and 24.2 minutes represents the customers who will receive a free meal, and the area to the right of 24.2 minutes represents the customers who will not receive a free meal.

The normal distribution is a common probability distribution which follows a symmetric, bell-shaped curve. It is often used to describe real-world phenomena such as customer wait times in restaurants, since it is an effective tool for modeling variation in large datasets. The normal distribution can be determined by two parameters: the mean and the standard deviation. The mean represents the average wait time, while the standard deviation describes how the wait times vary.

In this case, the normal distribution has a mean of 20 minutes and a standard deviation of 4 minutes. This means that the average wait time is 20 minutes and that the wait times may vary by up to 4 minutes. The area of the graph between 0 and 24.2 minutes can be seen as the customers who will receive a free meal, as these customers waited longer than the advertised maximum wait time. The area of the graph to the right of 24.2 minutes represents the customers who will not receive a free meal, as these customers did not wait longer than the advertised maximum wait time.

By proposing a maximum wait time of 24.2 minutes, the company will not be losing out on any profit. This is because only 1% of customers will be receiving a free meal, and the cost of this will be more than offset by the increased customer satisfaction due to faster service.

Alex picked 15 ⅘ kilograms of red apples and 9 ⅗ kilograms of green apples. What is the total mass of the apples Alex picked?

Answers

The total mass of the apples Alex picked is 25 2/5 kilograms.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants

To find the total mass of the apples Alex picked, we need to add the mass of the red apples and the mass of the green apples.

First, let's convert the mixed numbers to improper fractions to make the addition easier:

15 ⅘ = 15 + 8/10 = 15 + 4/5 = 75/5 + 4/5 = 79/5

9 ⅗ = 9 + 6/10 = 9 + 3/5 = 45/5 + 3/5 = 48/5

Now we can add the fractions:

79/5 + 48/5 = (79 + 48)/5 = 127/5

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 1 in this case:

127/5 = 25 2/5

Therefore, the total mass of the apples Alex picked is 25 2/5 kilograms.

The path of a firecracker is modeled by the equation h(t) = -t^2 + 19t + 14, where h(t) is the hight, in feet, of the firecracker at any given time, t. What is the hight of the firecracker after 4 seconds from launch.

A. 63 feet
B. 68 feet
C. 70 feet
D. 74 feet​

Answers

the height of the firecracker after 4 seconds from launch is 68 feet.

To find the height of the firecracker after 4 seconds from launch, we need to plug in t = 4 into the equation h(t) =[tex]-t^2[/tex] + 19t + 14. This gives us h(4) =[tex]-4^2[/tex] + 19(4) + 14 = -16 + 76 + 14 = 68 feet. Therefore, the height of the firecracker after 4 seconds from launch is 68 feet.

To find the height of the firecracker after 4 seconds from launch, we need to use the equation h(t) =[tex]-t^2[/tex] + 19t + 14. This equation models the path of the firecracker, with h(t) being the height in feet of the firecracker at any given time, t. When we plug in t = 4, we get h(4) = [tex]-4^2[/tex] + 19(4) + 14 = -16 + 76 + 14 = 68 feet. So, the height of the firecracker 4 seconds after launch is 68 feet. This equation allows us to calculate the height of the firecracker at any given time, making it a useful tool for predicting the trajectory of the firecracker.

Roy, Sydney, Mila, Taniya invested money on a project. Roy invested twice as Sydney. Mila invested twice as Roy. Taniya invested half as Mila. If the total profit of the project is $27,000. What percentage of profit Mila should receive?

Answers

Mila should receive 44.44% of the profit.

What is equations?

An equation is a statement that asserts the equality of two expressions, typically with one or more variables. Equations are used to represent relationships between different quantities, such as the relationship between the length and width of a rectangle or the relationship between the time and distance traveled by an object.

What is profit?

Profit is the financial gain that is earned by a business or an individual after all expenses and costs have been subtracted from revenue or income. It is the difference between the amount earned from sales or services and the costs incurred to produce or provide those goods or services.

In the given question,

Let's begin by determining the amount of money each person invested in the project.

Let Sydney's investment be x.

Roy's investment is twice Sydney's, so Roy invested 2x.

Mila's investment is twice Roy's, so Mila invested 2(2x) = 4x.

Taniya's investment is half of Mila's, so Taniya invested 0.5(4x) = 2x.

The total amount invested is x + 2x + 4x + 2x = 9x.

Now, we need to find the percentage of profit Mila should receive. Since the profit is shared in proportion to the amount invested, Mila should receive a fraction of the profit equal to her investment divided by the total investment.

Mila's share = (Mila's investment) / (Total investment) x (Total profit)

Mila's share = (4x / 9x) x 27000

Mila's share = 12000

So Mila should receive $12,000 of the profit. To find the percentage of profit Mila should receive, we can divide her share by the total profit and multiply by 100:

Percentage of profit Mila should receive = (Mila's share / Total profit) x 100%

Percentage of profit Mila should receive = (12,000 / 27,000) x 100%

Percentage of profit Mila should receive = 44.44%

Therefore, Mila should receive 44.44% of the profit.

Step-by-step explanation:

Arthur can paint a wall in 45 minutes alone. Cheyenne can paint a wall in 1 hour alone. One
room has 4 walls. How many minutes will it take them to paint 3 rooms together?

Answers

The time needed to paint 3 rooms together is given as follows:

308.4 minutes.

How to obtain the time needed?

The time needed is obtained applying the proportions in the context of the problem.

First we use the together rate, which is the sum of each separate rate, for the time needed to paint a single wall, hence:

1/x = 1/45 + 1/60

1/x = 7/180

7x = 180

x = 180/7

x = 25.7 minutes per wall.

The number of walls in 3 rooms is given as follows:

3 x 4 = 12 walls.

Thus the time needed to paint the 3 rooms is given as follows:

25.7 x 12 = 308.4 minutes.
