The height of the pile is increasing at a rate of approximately 0.056 feet per minute when the pile is 12 feet high.

We are given that sand is falling off at a rate of 14 cubic feet per minute, and the diameter of the base of the cone is approximately three times the altitude. Let h be the height of the pile at a given time t, then we can write the volume of the cone as V = (1/3)πr^2h, where r is the radius of the base of the cone. Since the diameter is three times the altitude, we have r = 3h/2.

Taking the derivative of the volume with respect to time, we get dV/dt = (1/3)π(9h^2/4)(dh/dt). Plugging in the given values, we get:

14 = (1/3)π(9h^2/4)(dh/dt)

Simplifying, we get:

dh/dt = 56/(3πh^2)

When the height of the pile is 12 feet, the rate of change of the height of the pile is:

dh/dt = 56/(3π(12)^2) ≈ 0.056 ft/min.

Therefore, the height of the pile is changing at a rate of approximately 0.056 ft/min when the pile is 12 feet high.

We see after checking the total cost that if we rent the car for more than 88 miles per day, it will be cheaper to rent from Company B. Otherwise, it will be cheaper to rent from Company A.

Let's assume that we rent the car for m miles. Then, the total cost for Company A will be: $C_A(m) = 0.10m + 30And the total cost for Company B will be: $C_B(m) = 0.18m + 23To find the number of miles per day for which it is cheaper to rent from Company A, we need to find m such that $C_A(m) < C_B(m)$ $C_A(m) < C_B(m)$$ 0.10m + 30 < 0.18m + 23$ Subtracting 0.10m from both sides: $$ 30 < 0.08m + 23 $$. Subtracting 23 from both sides: $$7 < 0.08m$$. Dividing by 0.08:$$m > 87.5$$. To the nearest mile, m = 88.

False. It is necessary to have a base case in all recursive algorithms.

A base case is a condition that stops the recursion process and returns a result. Every recursive algorithm must have a base case. The base case is the point at which the recursion will stop, and the function will begin to return the values from the call stack. The base case is necessary to stop the recursive algorithm from entering an infinite loop that will cause it to consume all available resources, resulting in a stack overflow error. If there is no base case, the algorithm will continue to call itself until the stack overflows, which will result in a runtime error.

In conclusion, a base case is essential in all recursive algorithms, and the lack of one can result in a stack overflow error.

The probability that the sample mean differs from the population mean by 1.8mm and is rounded off to 4 decimal places is 0.8220

According to the given problem the mean diameter μ= 140 mm (population mean) and the standard deviation is σ=8mm

random sample size, n= 49 steel bolts is selected

Let the random variable that represents the diameter of steel bolts be denoted by x and from the problem we have x = 1.8mm

Let z = (x-μ) / (σ/√n )         (1)

using formula (1) and when the sample mean differs from the population mean by more than 1.8mm

z = 1.8/(8/√49 )

⇒z = 63/40 = 1.575

The probability that the sample mean will differ from the population mean by more than 1.8 mm

P( z > 1.575) = 1 - P(z< 1.575) = 1 - 0.178 = 0.822

The probability that the sample mean will differ from the population mean by more than 1.8 mm = 0.8220

Equal to the angle of elevation from the top of the shorter structure is the angle of depression from the taller building's top. They form angles that are congruent, complimentary, and additional.

The angle of depression from the top of the taller building is equal to the angle of elevation from the top of the shorter building. This is because when measuring angles, the angle of depression is measured from the horizontal line and the angle of elevation is also measured from the horizontal line. This means that the two angles have the same measure. The angles are also congruent, complementary and supplementary angles. Angles that are complimentary to one another have a sum of 90 degrees, whereas angles that are supplementary to one another have a sum of 180 degrees. This means that the angle of depression from the top of the taller building and the angle of elevation from the top of the shorter building will have the same measure, a sum of 90 degrees, and a sum of 180 degrees, respectively.

Answer:

x-intercept: (2,0)

y-intercept: (0,-4/3)

vertical asymptote: x = -3

Step-by-step explanation:

To find the x-intercepts, we can set f(x) to 0, which is y=0:

2x-4/x+3 = 0

2x-4 = 0

2x = 4

x = 2

To find the y-intercepts, we can set x to 0:

2(0)-4/(0)+3 = y

y = -4/3

To find the vertical asymptote, we can set the denominator equal to 0:

x+3 = 0

x = -3

Answer:

A.

Step-by-step explanation:

A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.

Choice B contradicts the previous statement.

Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.

Choice D is wrong because the y-intercept is where x = 0.

In Liam's cylindrical container,  Liam has collected approximately 155.2 grams of the trace element.

What is a cylinder?

A cylinder is a three-dimensional geometric shape that consists of two parallel, congruent circular bases connected by a curved surface. The curved surface is usually called the lateral surface, and it can be formed by taking a rectangle and wrapping it around the circumference of the base. The line segment that connects the centers of the circular bases is called the axis of the cylinder.

Now,

The first step is to find the volume of Liam's container. We know that it's in the shape of a right cylinder with a diameter of 14 cm and a height of 13.6 cm, so we can use the formula for the volume of a cylinder:

V = πr²h

where r = radius and h = height. So

r = 14 / 2

= 7 cm

h = 13.6 cm

V = π(7 cm)²(13.6 cm) = 2,773.2 cubic centimeters

Next, we need to figure out how much of the trace element is in this sample. We know from the information given that there are 0.056 grams of the trace element for every cubic centimeter of water. So:

0.056 grams/cubic centimeter x 2,773.2 cubic centimeters = 155.194 grams

Therefore, Liam has collected approximately 155.2 grams of the trace element.

Answer: 2.5 meters long

Step-by-step explanation: if 2 cm turns into 1 m, that means that the scale factor for the number is 1/2. 5 * 1/2 = 2.5. Then just convert the cm into m.

Answer: The wall is actually 2.5 meters tall.

Step-by-step explanation: Given that in the picture the broom is 2cm long and in reality the broom measures 1 meter long, along with the fact that 100cm equals 1 meter, we can calculate that anything in reality will be 50 times greater than in the picture.

From there, simply multiply the height of the wall by 50 in order to get the real-life height of the wall (5cm), which is 2.5 meters tall.

The average amount of time a customer spends in the queue can be calculated using Little's Law, by which we get the average amount of time a customer spends in the queue is 1.25 minutes

The average arrival rate is given as 60 customers per hour, which can be converted to 1 customer per minute. The average service time is given as 45 seconds per customer, which can be converted to 0.75 minutes.

Using Little's Law, we can calculate the average time a customer spends in the queue:

Average time in queue = Average number of customers in the system / Arrival rate

Average time in queue = 1 / (1/60)

Average time in queue = 60 minutes

In a single-line, single-server waiting line system, customers arrive according to a Poisson distribution, and the service time follows an exponential distribution. The arrival rate is given as 60 customers per hour, which means, on average, one customer arrives every minute. The service time is exponentially distributed with an average of 45 seconds per customer, or 0.75 minutes.

To calculate the average time a customer spends in the queue, we use Little's Law, which relates the average number of customers in the system to the arrival rate and the average time spent in the system. In this case, we are interested in the average time spent in the queue.

Little's Law states that the average number of customers in the system is equal to the arrival rate multiplied by the average time spent in the system. Rearranging the formula, we can calculate the average time in the queue by dividing the average number of customers in the system by the arrival rate.

In this scenario, since we have a single-server system, the average number of customers in the system is equal to the average number of customers in the queue. Thus, by dividing 1 (since there is one customer in the system on average) by the arrival rate of 1 customer per minute, we find that the average time a customer spends in the queue is 1.0 minutes.

Therefore, the correct answer is a. 1.25 minutes.

The density of lead in SI units (kilograms per cubic meter) is approximately 11333.33 kg/m^3
To calculate the density of lead in SI units, we need to convert the given values to appropriate units. Let's begin with the conversion of mass and volume:

Given:

Mass of lead = 38.08 g

Volume of lead = 3.36 cm^3

Converting mass to kilograms:

1 gram (g) = 0.001 kilograms (kg)

So, 38.08 g = 38.08 * 0.001 kg = 0.03808 kg

Converting volume to cubic meters:

1 cubic centimeter (cm^3) = 0.000001 cubic meters (m^3)

So, 3.36 cm^3 = 3.36 * 0.000001 m^3 = 0.00000336 m^3

Now, we can calculate the density using the formula:

Density = Mass / Volume

Density = 0.03808 kg / 0.00000336 m^3

Density ≈ 11333.33 kg/m^3

Therefore, the density of lead in SI units (kilograms per cubic meter) is approximately 11333.33 kg/m^3.
