Answer:

number of pennies = 19

number of dimes = 19

number of quarters = 45 - 2 × 19 = 45 - 38 = 7

Step-by-step explanation:

The total number of coins in the box is 45 . The coins consist of pennies, dimes and quarters.

The number of pennies is equal to the number of dimes. The remaining number is the quarters. Therefore,

number of pennies = a

number of dimes = a

number of dimes = 45 - 2a

1 dime = 0.1 dollars

1 penny = 0.01 dollars

1 quarters = 0.25 dollars

Thee total cost can be expressed as follows

3.84 = a(0.01) + a(0.1) + 0.25(45 - 2a)

3.84 = 0.01a  + 0.1a + 11.25  - 0.5 a

3.84 = -0.39 a + 11.25

3.84 - 11.25 = -0.39 a

-7.41  = -0.39 a

divide both sides by -0.39

a = -7.41/-0.39

a = 19

number of pennies = 19

number of dimes = 19

number of quarters = 45 - 2 × 19 = 45 - 38 = 7

The vertical component of velocity can be zero at specific points in the motion of an object.

What is Velocity?

Velocity is a vector quantity that describes the rate of change of an object's position in space over time. It is defined as the displacement of an object divided by the time interval during which the displacement occurred.

The vertical component of velocity can be zero at specific points in the motion of an object. This occurs when the object reaches the highest point in its vertical motion and begins to fall back down. At this point, the vertical component of velocity changes direction from upward to downward, and its magnitude becomes zero. This moment is known as the "instant of maximum height" or "instant of maximum altitude." Beyond this point, the vertical component of velocity becomes negative, indicating that the object is moving downward.

The angular area of the HST's field of view is 25 square degrees.

The field of view is the extent of the sky that the Hubble Space Telescope (HST) can observe at a given time. It is usually measured in degrees.

To calculate the angular area, we can use the formula for the area of a circle:

Area = π * (angular size/2)^2

Where π is a mathematical constant approximately equal to 3.14, and the angular size is in degrees.

Let's say the angular size of the HST's field of view is 10 degrees.

First, we divide the angular size by 2:

10 degrees / 2 = 5 degrees

Next, we square the result:

5 degrees * 5 degrees = 25 square degrees

The Tesla Model S P100D, when pushed to its limit in "Ludicrous mode," can accelerate to 60 mph in an astonishingly short amount of time. The acceleration profile of the vehicle during the first 3.0 seconds can be modeled using the equation x = (35 m/s³)t + 14.6 m/s² - (1.5 m/s³)t² for 0 s ≤ t ≤ 0.40 s and x = 14.6 m/s² - (1.5 m/s³)t² for 0.40 s ≤ t ≤ 3.0 s.

Explanation:

During the initial phase of acceleration from 0 s to 0.40 s, the equation x = (35 m/s³)t + 14.6 m/s² - (1.5 m/s³)t² describes the motion of the Tesla Model S P100D. This equation includes a linear term, (35 m/s³)t, and a quadratic term, -(1.5 m/s³)t². The linear term represents the linear increase in velocity over time, while the quadratic term accounts for the decrease in acceleration due to drag forces.

After 0.40 s, the quadratic term dominates the equation, and the linear term is no longer significant. Therefore, the equation x = 14.6 m/s² - (1.5 m/s³)t² applies for the remaining duration until 3.0 s. This equation allows us to calculate the position of the car as a function of time during this phase of acceleration.

Now, to determine the time it takes for the Tesla Model S P100D to accelerate to 60 mph, we need to convert 60 mph to meters per second. 60 mph is equivalent to approximately 26.82 m/s. We can set the position x equal to the distance covered during this acceleration period (x = distance) and solve the equation x = 26.82 m/s for t.

It takes around 2.34 seconds for the Tesla Model S P100D in "Ludicrous mode" to accelerate to 60 mph.

To find out how long it takes for the Tesla Model S P100D to accelerate to 60 mph, we need to convert 60 mph to meters per second (m/s) since the given acceleration equation is in m/s.

1 mile = 1609.34 meters

1 hour = 3600 seconds

Converting 60 mph to m/s:

60 mph * (1609.34 meters / 1 mile) * (1 hour / 3600 seconds) ≈ 26.82 m/s

Now, we can set up the equation and solve for time:

x = (35 m/s^3)t^3 + (14.6 m/s^2)t^2 - (1.5 m/s^3)t

To find the time when the velocity reaches 26.82 m/s, we set x equal to 26.82 and solve for t:

26.82 = (35 m/s^3)t^3 + (14.6 m/s^2)t^2 - (1.5 m/s^3)t

Since the equation is a cubic equation, we can use numerical methods or calculators to solve it. Using a numerical solver, we find that the time it takes to accelerate to 60 mph is approximately 2.34 seconds.

Therefore, it takes around 2.34 seconds for the Tesla Model S P100D in "Ludicrous mode" to accelerate to 60 mph.

A function f such that f '(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f is f(x) = 3x^4/4 + 729/4.

In the given question, we have to find a function f such that f'(x) = 3x^3 and the line 81x + y = 0 is tangent to the graph of f.

The given function is f'(x) = 3x^3.

No integrating on both side,

f(x) = \(\int3x^3dx\) + C

f(x) = 3x^4/4 + C

As given, the line 81x + y = 0 is tangent to the graph of f.

So, slope at point of tangent; f'(x) = -81

So, 3x^3 = -81

Divide by 3 on both side, we get

x^3 = -27

Taking cube root on both side, we get

x = -3

So putting the value of x in 81x + y = 0, we get

y = 243

Thus, f(x) passes through (-3, 243).

So, 243 = 3/4(81) + C

Multiply by 4 on both side, we get

972 = 243 + 4C

Subtract 243 on both side, we get

4C = 729

Divide by 4 on both side, we get

C = 729/4

So, f(x) = 3x^4/4 + 729/4

If there are 8 pieces of strawberry candy and 7 pieces of rhubarb candy then I have 77 different methods to give this candy to kids who have donated $5.

Number of strawberry candy = 8 pieces

Number of rhubarb candy = 7 pieces

Find the number of ways for equally distributing candy to all 5 children

Using formula:

→ ⁿCr = n!/r(n-r)!

          = 8!/5!3!

          = 8×7×6×5!/5! 3 × 2 ×1

          = 8×7×6/6

The revenue from hedging minus the revenue from not hedging receivables can be calculated by considering the net exposure to the Malaysian ringgit, the forward rate, and the probabilities of different exchange rate outcomes.

To calculate the revenue from hedging minus the revenue from not hedging receivables, we need to compare the outcomes of hedging versus not hedging in terms of the exchange rate.

If Money Corp. hedges its receivables, it will lock in the forward rate of $.23 for the net exposure of MYR1,500,000. Therefore, the revenue from hedging will be:

Revenue from Hedging = Net Exposure * Forward Rate = MYR1,500,000 * $.23

To calculate the revenue from not hedging, we consider the probabilities associated with each exchange rate outcome. The expected revenue from not hedging is calculated by multiplying each possible value by its corresponding probability and summing the results:

Expected Revenue from Not Hedging = (Revenue at $.20 * Probability of $.20) + (Revenue at $.25 * Probability of $.25)

An interval variable is one that has numerical values and still makes sense when you average the data values. This type of variable is used in statistics and data analysis to measure continuous data, such as temperature, time, or weight.

Interval variables are based on a scale that has equal distances between each value, meaning that the difference between any two values is consistent throughout the scale.

Interval variables can be used to create meaningful averages or means. The arithmetic mean is a common method used to calculate the average of interval variables. For example, if a researcher is studying the temperature of a city over a month, they can use interval variables to represent the temperature readings. By averaging the temperature readings, the researcher can calculate the mean temperature for the month.

In summary, interval variables are essential in statistics and data analysis because they can be used to measure continuous data and create meaningful averages. They are based on a scale with equal distances between each value and are commonly used in research studies.

When the null hypothesis is true as an equality, the probability of committing a type I error is denoted by α and it is equal to the significance level.

A null hypothesis is a type of hypothesis used in statistics that proposes that no statistical significance exists in a series of given observations. The null hypothesis is a hypothesis that implies that no statistical significance exists in a set of given observations. It is the default assumption in which one begins. In null hypothesis testing, the null hypothesis is typically the statement that there is no difference between two measured phenomena.Type I errorWhen the null hypothesis is correct and we reject it, a Type I error occurs. A type I error, also known as a false positive, occurs when the null hypothesis is rejected when it is true. In other words, the null hypothesis (H0) is correct, but we reject it. A type I error can occur when testing a statistical hypothesis because statistical tests involve a probability of making a mistake.

The null hypothesis is accepted if the value obtained from the test statistic falls within the range of the null distribution. If the test statistic falls outside of the range of the null distribution, the null hypothesis is rejected in favor of the alternative hypothesis. The decision to reject or accept the null hypothesis is based on the comparison of the test statistic to the critical value.
