Step-by-step explanation:

Given that:

Speed from hive to flowerbed = 10 ft/s

Time used in flowerbed = 10 minutes

Speed from flowerbed to hive = 6ft/s

Total time at which bee is away from hive = 12 minutes

Equation to find distance of flowerbed from hive :

Let distance from hive to flowerbed = d

Time taken = distance / speed

Time taken from hive to flowerbed = d/ 10

Time used in flowerbed = 10 minutes = (10 * 60) = 600 seconds

Time taken from flowerbed to hive = d/6

Total time away from hive = 12 mins = (12 * 60) = 720 seconds

A. What equation can you use to find the distance of the flowerbed from the​ hive?

Distance can be obtained from the formula :

d/10 + 600 + d/6 = 720

B. How far is the flowerbed from the​ hive?

d/10 + 600 + d/6 = 720

Take L. C. M of 10 and 6 = 30

(3d + 18000 + 5d) = 21600

8d + 18000 = 21600

8d = 21600 - 18000

8d = 3600

d = 3600/8

d = 450

Distance of flowerbed from hive = 450 fts

Answer:

Yes

Step-by-step explanation:

The Elephant Building is 335 feet high. A real Asian elephant is 12 feet tall. If 29 real elephants could stand on top of each other, would they reach the top of the building?

They are asking if 29 12' elephants are as tall as as a 335' building:

29 × 12' = 348' elephant stack

because 348' is taller than 335' building then yes, 29 staked elephant would reach and pass the top of a 335' building.  

The acceleration of the hare, once it begins to slow down, is \($\frac{-11.52 - 12v_{\text{hare2}} + 85}{6}$\)\(m/s$^2$\), the total time the hare is moving in \($4.8 + 12 + t_{\text{hare3}}$\) seconds, and the acceleration of the tortoise \(($a_{\text{tortoise}}$)\) is to be determined.

To solve the problem in detail:

Hare's initial acceleration \(($a_{\text{hare1}}$) = 1 m/s$^2$\)

Hare's acceleration after constant speed \(($a_{\text{hare2}}$) = ?\) (to be determined)

Hare's time of constant speed \(($t_{\text{hare2}}$) = 12 s\)

Hare's final displacement \(($s_{\text{hare}}$) = 85 m\)

Step 1: Finding the hare's acceleration once it begins to slow down.

Using the equation of motion, we can determine the acceleration:

\(\[s_{\text{hare}} = v_{\text{hare1}} \cdot t_{\text{hare1}} + \frac{1}{2} \cdot a_{\text{hare1}} \cdot t_{\text{hare1}}^2 + v_{\text{hare2}} \cdot t_{\text{hare2}} + \frac{1}{2} \cdot a_{\text{hare2}} \cdot t_{\text{hare2}}^2\) \\\(85 = 0 + \frac{1}{2} \cdot 1 \cdot (4.8)^2 + v_{\text{hare2}} \cdot 12 + \frac{1}{2} \cdot a_{\text{hare2}} \cdot (12)^2\]\)

Solving for \($a_{\text{hare2}}$\), we get:

\(\[a_{\text{hare2}} = \frac{-11.52 - 12v_{\text{hare2}} + 85}{6}\]\)

Step 2: Finding the total time the hare is moving.

The total time the hare is moving is the sum of the time for acceleration \(($t_{\text{hare1}}$)\), time at a constant speed \(($t_{\text{hare2}}$)\), and the time to decelerate to rest \(($t_{\text{hare3}}$)\):

\(\[t_{\text{total hare}} = t_{\text{hare1}} + t_{\text{hare2}} + t_{\text{hare3}}\]\)

\(\[t_{\text{total hare}} = 4.8 + 12 + t_{\text{hare3}}\]\)

Step 3: Finding the acceleration of the tortoise.

The tortoise accelerates uniformly for the entire distance, so its acceleration \(($a_{\text{tortoise}}$)\) is constant.

The person's total salary over the first 6 years is $231,750.

To determine the person's total salary over the first 6 years, we need to calculate the sum of the salary for each year.

Given information:

- Initial salary: $34,000

- Annual raise: $1,850

- Number of years: 6

To calculate the total salary, we can use the arithmetic progression formula:

[ S = frac{n}{2} left(2a + (n - 1)dright) ]

Where:

- ( S ) is the sum of the salaries

- ( n ) is the number of terms (years)

- ( a ) is the first term (initial salary)

- ( d ) is the common difference (annual raise)

Substituting the given values, we have:

[ S = frac{6}{2} left(2(34000) + (6 - 1)(1850)right) ]

Simplifying the expression:

[ S = 3 left( 68000 + 5 times 1850 right) ]

[ S = 3 left( 68000 + 9250 right) ]

[ S = 3 times 77250 ]

[ S = 231750 ]

Therefore, the person's total salary over the first 6 years is $231,750.

(a) The expression for a Riemann sum of a function f on an interval [a, b] is Δx = (b-a)/n

(b) If f(x)⩾ 0, then the geometric interpretation of a Riemann sum is infinity

(c) If f(x) takes on both positive and negative values, then the geometric interpretation of a Riemann sum is infinity

Riemann sums are an important tool in calculus for approximating the area under a curve. They are used to estimate the value of a definite integral, which represents the area bounded by the curve and the x-axis on a given interval. In this explanation, we will discuss the expression for a Riemann sum, its notation, and its geometric interpretation.

(a) Expression for a Riemann sum:

A Riemann sum is an approximation of the area under a curve using rectangles. We divide the interval [a, b] into n subintervals, each of length Δx=(b−a)/n. The notation used to represent this is:

Δx = (b-a)/n

(b) Geometric interpretation of a Riemann sum when f(x)⩾ 0:

If f(x) is always non-negative, the Riemann sum represents an approximation of the area between the curve and the x-axis on the interval [a, b].

Each rectangle has a positive area, which contributes to the overall area under the curve. The sum of the areas of the rectangles approaches the true area under the curve as the number of subintervals n approaches infinity.

(c) Geometric interpretation of a Riemann sum when f(x) takes on both positive and negative values:

When f(x) takes on both positive and negative values, the Riemann sum represents the net area between the curve and the x-axis on the interval [a, b].

Each rectangle may have a positive or negative area, depending on the sign of f(xi).

The positive areas represent regions where the curve is above the x-axis, and the negative areas represent regions where the curve is below the x-axis.

In conclusion, Riemann sums are used to approximate the area under a curve on an interval [a, b]. The expression for a Riemann sum involves dividing the interval into n subintervals and approximating the area under the curve using rectangles.

The probability that the second card is another 8 is  approximately 0.045

There are 52 cards in a standard deck, and after drawing the first card, there are only 51 cards remaining.

The probability of drawing an 8 as the first card is 4/52, since there are four 8s in the deck.

Since the first card is not replaced, there are only three 8s remaining in the deck.

Therefore, the probability of drawing another 8 as the second card, given that the first card is an 8 and was not replaced, is 3/51.

The correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

To calculate the probability of a cash flow being between $16,000 and $19,000, we can use the standard deviation and assume a normal distribution.

We are given that the average cash flow is $14,000 with a standard deviation of $5,000. These values are necessary to calculate the probability.

The probability of a cash flow falling within a certain range can be determined by converting the values to z-scores, which represent the number of standard deviations away from the mean.

First, we calculate the z-score for $16,000 using the formula: z = (x - μ) / σ, where x is the cash flow value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get z1 = (16,000 - 14,000) / 5,000.

z1 = 2,000 / 5,000 = 0.4.

Next, we calculate the z-score for $19,000: z2 = (19,000 - 14,000) / 5,000.

z2 = 5,000 / 5,000 = 1.

Now that we have the z-scores, we can use a standard normal distribution table or calculator to find the corresponding probabilities.

Subtracting the probability corresponding to the lower z-score from the probability corresponding to the higher z-score will give us the probability of the cash flow falling between $16,000 and $19,000.

Looking up the z-scores in a standard normal distribution table or using a calculator, we find the probability for z1 is 0.6554 and the probability for z2 is 0.8413.

Therefore, the probability of the cash flow being between $16,000 and $19,000 is 0.8413 - 0.6554 = 0.1859, which is approximately 18.59%.

So, the correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.
