Answer: First find your given information:

D=6 miles (3 miles there + 3 miles back)

T=1 hour

Vwind= 3 mph

We're going to assume that the wind's velocity is always in opposite direction to Mr. Lee so:

VFinal = VMr. Lee - Vwind

We also know that VFinal=D/T

So D/T = VMr. Lee - Vwind

Rearrange to get VMr. Lee = D/T + Vwind

Plug in your given info to get VMr. Lee = (6 miles)/(1 hours) + 4 mph or 10 mph

Tno wind= D/VMr. Lee or (6 miles/10 mph)

Tno wind=0.6 hours

Answer:

  540x⁴

Step-by-step explanation:

You want the 3rd term of the expansion of (x +6)⁶.

The k-th term of (a +b)^n is ...

   C(n, k)a^(n-k)b^k

where terms are numbered 0 to n.

The third term of (x+6)⁶ is the above expression with k=2:

  C(6, 2)a⁴b²

Where a=x and b=6, this is ...

  15x⁴6² = 540x⁴

__

Additional comment

C(n, k) is the function that represents the number of combinations of n things taken k at a time:

  C(n, k) = n!/(k!(n-k)!)

  C(6, 2) = 6!/(2!·4!) = 6·5/(2·1) = 15

If Malcolm trains on his kayak every weekend. The speed is 12km/h and the distance is 31.5km.

Let's call Malcolm's paddling speed in still water "v".

When paddling upstream, Malcolm is fighting the current, so his effective speed is v - 3 km/h. And when paddling downstream, his effective speed is v + 3 km/h.

The time it takes for him to paddle upstream= 3.5 hours

Distance he covers in this time =  (v - 3) * 3.5.

The time it takes for him to paddle downstream = 2.1 hours

Distance he covers in this time = (v + 3) * 2.1.

Let  set the sum of these two distances equal to each other and solve for v:

(v - 3) * 3.5 = (v + 3) * 2.1

Expanding both sides:

3.5v - 10.5 = 2.1v + 6.3

Subtracting 2.1v from both sides:

1.4v - 10.5 = 6.3

Adding 10.5 to both sides:

1.4v = 16.8

Dividing both sides by 1.4:

v = 12 km/h

So Malcolm's paddling speed in still water is 12 km/h. To find the distance he paddles upstream, we can use the formula (v - 3) * 3.5, which gives us:

(12 - 3) * 3.5 = 9 * 3.5 = 31.5 km

Therefore  the distance Malcolm paddles upstream is 31.5 km.

The average with two digits after the decimal point followed by a newline is 7.4

An integer is a whole number, either positive or negative, that does not have any decimal points. Non-negative integers are those that are greater than or equal to zero.

To write such a program, we can use a loop to continuously read in integers from the user until a negative integer is entered. We then ignore the negative integer and calculate the maximum and average of the non-negative integers that were entered.

The maximum is simply the largest integer in the set. We can use a variable to keep track of the largest integer as we read in the input. At the end of the loop, the variable will hold the maximum value.

The average is the sum of all the integers divided by the total number of integers.

We add each non-negative integer to the sum and increment the count. At the end of the loop, we divide the sum by the count to get the average.

To output the average with two digits after the decimal point, we can use the printf method, which allows us to format our output. The format string "%.2f\n" specifies that we want to output a floating-point number with two decimal places followed by a newline character.

=> (15 + 20 + 0 + 3 - 1) / 5 = 7.4

In summary, a program that takes any number of non-negative integers as input, and outputs the max and average can be written using a loop, variables to keep track of the maximum, sum, and count, and the printf method to format the output. Understanding the basics of integers and how to perform calculations with them is essential for programming and statistical analysis.

Answer:

Step-by-step explanation:

The rate of deflation of the hot-air balloon is 0.25 feet per minute. Let's represent the diameter of the balloon at any time t in minutes as D(t).

We know that D(0) = 14 feet (initial diameter) and we want to find x when D(x) = 8 feet.

Using the fact that the rate of change of D with respect to time is -0.25 (negative because the diameter is decreasing), we can set up a differential equation:

dD/dt = -0.25

Separating variables and integrating, we get:

∫(1/D) dD = ∫(-0.25) dt

ln|D| = -0.25t + C

where C is the constant of integration.

Using the initial condition D(0) = 14, we get:

ln|14| = C

C = ln(14)

Substituting this value of C into the equation, we get:

ln|D| = -0.25t + ln(14)

Taking the exponential of both sides, we get:

|D| = e^(-0.25t + ln(14)) = e^ln(14) e^(-0.25t) = 14 e^(-0.25t)

Since we are only interested in the positive value of D, we can drop the absolute value sign:

D = 14 e^(-0.25t)

Now we can solve for x by setting D = 8:

8 = 14 e^(-0.25x)

Dividing both sides by 14, we get:

e^(-0.25x) = 8/14 = 4/7

Taking the natural logarithm of both sides, we get:

ln(e^(-0.25x)) = ln(4/7)

-0.25x = ln(4/7)

x = -4 ln(4/7) / 0.25

x ≈ 6.21

Therefore, it will take about 6.21 minutes for the balloon to shrink to a diameter of 8 feet.

(C) 48 = V2 -2 -2 -2 - 3 = 4√3 correctly uses prime factorization to write V48 in simplest form.

In number theory, the breakdown of a composite number into a sum of smaller integers is known as integer factorization.

The procedure is known as prime factorization if these factors are further limited to prime numbers.

The technique of expressing all numbers as the product of primes is known as prime factorization.

So, let's take something like the number 20 as an example.

It can be divided into two components.

"Well, that's 4 times 5," we can respond.

Observe that 5 is a prime number. The number 4 is not a prime.

So, it is necessary to write 48 as the product of its prime elements:

2 * 3 * 2 * 2 * 2

Then,

√48 = √(2 * 2 * 2 * 2 * 2)

Lower radical form: √48

The end behavior of this the end behavior of this polynomial is positive, meaning that as x approaches positive and negative infinity, the y values approach positive infinity.

The end behavior of a polynomial can be determined by looking at the degree (highest exponent) and the leading coefficient (coefficient of the highest degree term). If the degree is even and the leading coefficient is positive, the end behavior of the polynomial is positive, meaning that as x approaches positive and negative infinity, the y values approach positive infinity. Similarly, if the degree is even and the leading coefficient is negative, the end behavior of the polynomial is negative, meaning that as x approaches positive and negative infinity, the y values approach negative infinity. If the degree is odd and the leading coefficient is positive, the end behavior of the polynomial is positive, and if the degree is odd and the leading coefficient is negative, the end behavior of the polynomial is negative.For example, consider a polynomial of degree 5, f(x) = 3x5 + 2x4 - 3x2 + 4. The leading coefficient is 3, which is positive, and the degree is 5, which is odd.

The angles m∠MON and m∠LOM form one of the interior angles of a rectangle, hence they are complementary as they add up to 90°.

we shall solve for x as follows:

2x + 7x + 9 = 90

9x + 9 = 90

9x = 90 - 9 {subtract 9 from both sides}

9x = 81

x = 81/9 {divide through by 9}

x = 9

m∠MON = 7(9) + 9 = 72°

m∠LOM = 2(9) = 18°

On the other hand, BIC (Bayesian Information Criterion) is a criterion for model selection based on the Bayesian approach. It is also used to compare different models, but it takes into account the complexity of the model. BIC tends to favor simpler models, and it is more focused on finding the model that is most likely to be true given the data.
