Answer:answer is b

Step-by-step explanation:it’s miles per hour not hours per mile

The form that most quickly reveals the zeros of the function is b because it is already factored the zeros are -8 and 2.

We are given that;

Functions f(x) = -1/2(x+3)^2+25/2, f(x)= -1/2(x-2)(x+8) and f(x)= -1/2x^2-3x+8

Now,

The zeros of a quadratic function are the points where the graph of the function intersects the x-axis. At the zeros of the function, the y-coordinate is 0 and the x-coordinate represents the zeros of the quadratic polynomial function1.

To find the zeros of a quadratic function in standard form (ax^2+bx+c), we can use the quadratic formula:

\(x = (-b ± sqrt(b^2-4ac)) / 2a^\\2\\\)

Now, let’s look at the three equivalent forms of f(x) given in your question. a. f(x) = -1/2(x+3)^2+25/2 b. f(x)= -1/2(x-2)(x+8) c. f(x)= -1/2x^2-3x+8

Therefore, by quadratic equations the answer will be -8 and 2.

The possible number of passengers on the flight over the past 5 days can range from 72 to 92 passengers

Since the mean number of passengers on a flight from Los Angeles to San Francisco is 82, we can assume that this is the average number of passengers over a period of time. To list the possible number of passengers on the flight over the past 5 days, we can use the range of values that are within one standard deviation of the mean.

Assuming a normal distribution of passengers on the flight, we can use the empirical rule to estimate the range of values within one standard deviation of the mean. The empirical rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean.

Therefore, the range of possible values for the number of passengers on the flight can be estimated as:

Mean - Standard deviation <= Number of passengers <= Mean + Standard deviation

Since we do not have the standard deviation of the data, we can use a conservative estimate of the standard deviation as 10% of the maximum capacity of the plane, which is 102 passengers. Therefore, the standard deviation can be estimated as 10.2 passengers.

Substituting these values into the formula, we get:

82 - 10.2 <= Number of passengers <= 82 + 10.2

Simplifying this inequality, we get:

71.8 <= Number of passengers <= 92.2

Therefore, the possible number of passengers on the flight over the past 5 days can range from 72 to 92 passengers, assuming a normal distribution of passengers and a standard deviation of 10.2 passengers.

The following parts can be solved by the concept of Area.

1. The area of the sprinkled lawn is 9π square feet, where π is approximately 3.14.

2. The area that the storm will affect is 113.1 square miles, where the value of π is approximately 3.14.

1. To find the area of the sprinkled lawn, we need to find the area covered by the sprinkler in one rotation and then multiply it by the number of rotations. The sprinkler sprays water 3 feet in every direction, so it covers a circular area with a radius of 3 feet. The area of a circle with a radius of 3 feet is given by the formula A = πr^2, where r is the radius of the circle.

Therefore, the area covered by the sprinkler in one rotation is 9π square feet (A = π x 3^2 = 9π). If the sprinkler rotates n times, then the total area covered by the sprinkler is n times the area covered in one rotation.

2. To find the area that the storm will affect, we need to find the area of the circle with a radius of 6 miles. The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Therefore, the area that the storm will affect is 36π square miles (A = π x 6^2 = 36π). To get a numerical value, we can use the approximation of π as 3.14, which gives us an area of approximately 113.1 square miles (A = 3.14 x 36 = 113.1).

Thus, the storm will affect an area of approximately 113.1 square miles.

Answer:

b is your answer (:

Step-by-step explanation:

Volume of ice =   10 X 10 X 20 = 2000 cm^3

tank volume increase will be the same

   100 x 40 x HEIGHT = 2000

            Height = 2000/ ( 100 X 40) =  .5 cm height increase

The melting of the ice block would raise the water level in the tank by approximately 0.5 centimeters. This can be answered by the concept of Volume

To calculate the amount of water that would be displaced by the ice block, we need to first find its volume, which is 10 x 10 x 20 = 2000 cubic centimeters. Since 1 cubic centimeter of water has a mass of 1 gram, the mass of the ice block would be 2000 grams or 2 kilograms.

When the ice block melts, it will turn into water and occupy the same volume, which would displace an equal amount of water in the tank. The volume of the tank is 100 x 40 x h, where h is the increase in water level. Setting the volume of the ice block equal to the increase in the water level, we get:

2000 = 100 x 40 x h

h = 0.5 centimeters

Therefore, the melting of the ice block would raise the water level in the tank by approximately 0.5 centimeters.

Step-by-step explanation:

The solution to the inequality (x-3)(x+5) ≤0 is  {x | -5 ≤ x ≤ 3}.

To solve the inequality (x-3)(x+5) ≤ 0, we can first find the critical points of the quadratic expression \(x^{2}\) + 2x - 15 by setting it equal to zero:

\(x^{2}\) + 2x - 15 = 0

(x + 5)(x - 3) = 0

This gives us two critical points: x = -5 and x = 3. These divide the real number line into three intervals:

Interval 1: x < -5

Interval 2: -5 ≤ x ≤ 3

Interval 3: x > 3

We can now test each interval to determine where the inequality (x-3)(x+5) ≤ 0 is true.

For interval 1, we can choose x = -6 as a test point:

(-6 - 3)(-6 + 5) = (-9)(-1) = 9 > 0

This means that the inequality is not true for any value of x less than -5.

For interval 3, we can choose x = 4 as a test point:

(4 - 3)(4 + 5) = (1)(9) = 9 > 0

This means that the inequality is not true for any value of x greater than 3.

For interval 2, we can choose x = 0 as a test point:

(0 - 3)(0 + 5) = (-3)(5) = -15 < 0

This means that the inequality is true for all values of x between -5 and 3, including the endpoints. Therefore, the solution to the inequality is:

{x | -5 ≤ x ≤ 3}

So the correct answer is {x | -5 ≤ x ≤ 3}.

If a function Llf(t)) exists but is not piecewise continuous, it means that there are points of discontinuity in its graph.

A function is said to be piecewise continuous if it is continuous on each interval within its domain, but may have discontinuities at the endpoints of those intervals. However, if a function Llf(t)) exists but is not piecewise continuous, it indicates that there are points of discontinuity within the intervals as well.

Discontinuities can manifest in different forms. One common type is a jump discontinuity, where the function "jumps" from one value to another at a particular point. Another type is a removable discontinuity, also known as a hole, where the function approaches a specific value but does not attain it at a particular point. There can also be oscillating discontinuities, where the function oscillates between two or more values indefinitely.

The existence of a function Llf(t)) despite its lack of piecewise continuity implies that there may be specific points or regions in the function where certain conditions or behaviors are present. These points of discontinuity can have significant implications for the behavior and properties of the function, and they need to be carefully considered when analyzing and interpreting its graph or applying mathematical operations involving the function.

According to the question, the probability that a new oil filter is needed given that the automobile's oil is being changed is 0.20.

To find the probability that a new oil filter is needed given that the automobile's oil is being changed, we can use conditional probability.

Let's define the events:

A: The car needs an oil change.

B: Both the oil and the filter need changing.

We are given:

\(P(A) = 0.30\) (probability that a car needs an oil change)

\(P(B) = 0.20\) (probability that both the oil and the filter need changing)

We need to find P(B|A), which represents the probability that both the oil and the filter need changing given that the car needs an oil change.

The conditional probability formula is given by:

\(\[ P(B|A) = \frac{P(A \cap B)}{P(A)} \]\)

In this case, P(A ∩ B) represents the probability that both events A and B occur.

Since we know that P(B) = 0.20, we can rewrite P(A ∩ B) as:

P(A ∩ B) = P(B) * P(A|B)

P(A|B) represents the probability that a car needs an oil change given that both the oil and the filter need changing.

We can rearrange the conditional probability formula as follows:

P(A ∩ B) = P(A|B) * P(B)

Substituting the given values:

P(A ∩ B) = P(A|B) * 0.20

Now we can solve for P(A|B):

\(\[ P(A|B) = \frac{P(A \cap B)}{P(B)} \]\)

\(\[ P(A|B) = \frac{P(A|B) \times 0.20}{0.20} \]\)

Simplifying, we can cancel out the 0.20:

P(A|B) = P(A|B)

This means that the probability of needing a new oil filter given that the oil is being changed is equal to the conditional probability of needing an oil change given that both the oil and the filter need changing.

Therefore, the probability that a new oil filter is needed given that the automobile's oil is being changed is equal to the conditional probability of needing an oil change given that both the oil and the filter need changing, which is 0.20.

Hence, the probability that a new oil filter is needed given that the automobile's oil is being changed is 0.20.

Three cards are drawn from a standard deck. Thus, the probability to get an ace, followed by a king, and then a queen, is  16/34,425

The formula for conditional probability is:

P(A∩B) = P(B|A) . P(A)

In the given problem:

P(ace) = 4 / 54

After an ace was drawn, the number of cards now is 51.

Hence,

P(king | ace) = 4/51

After the second drawn, the remaining cards is 50. Hence,

P(queen | (king | ace)) = 4/50

Therefore,

P(ace,king,queen) = 4/54 x 4/51 x 4/50 = 64 / 137,700 = 16/34,425

The margin of error is (31.15, 32.85).

The margin of Error is a statistical expression that is used to determine the percentage point by which the result arrived will differ from the value of the entire population, and it is calculated by dividing the standard deviation of the population by the sample size and lastly multiplying the resultant with the critical factor. A higher error indicates a high chance that the result of the sample reported may not be the true reflection of the whole population. The formula for the margin of error is calculated by multiplying a critical factor (for a certain confidence level) with the population standard deviation. Then the result is divided by the square root of the number of observations in the sample.

Mathematically, it is represented as,

Margin of Error = Z * ơ / √n

Given:

Number of people = n = 16

Mean = μ = $32

Standard deviation = σ = $7

Confidence level = 95%

Thus, the z value would be 1.96.

The confidence interval can be calculated as follows:

Confidence interval = μ ± z(σ/√n)

= 32 ± 1.96 × (7/16)

= 32 ± 0.85

= (31.15, 32.85)

Thus, the margin of error is (31.15, 32.85).
