A plant measured x inches tall last week and 8 inches tall this week.

1. Circle the expression that represents the number of inches the plant grev

this week. Explain how you know.

• X-8

• 8-x

Answers

Answer 1

The expression that represents the number of inches the plant grew this week is:

8 - x

This is because we are given that the plant measured x inches tall last week and 8 inches tall this week. The difference between the two measurements gives us the amount of growth that occurred over the course of the week. We subtract the initial height (x inches) from the final height (8 inches) to find the amount of growth. Therefore, the expression 8 - x represents the number of inches the plant grew this week.

what is expression?

In mathematics, an expression is a combination of numbers, symbols, and/or variables that are combined using mathematical operations such as addition, subtraction, multiplication, division, exponents, and more. Expressions can be simple or complex, and they are used to represent mathematical relationships and to perform calculations.

find f(t). ℒ−1 s (s + 1)2

Answers

The function f(t) corresponding to the Laplace transform ℋ(f(t)) = ℋ{s(t)} is:

f(t) = u(t) + 2te^(-t) + t^2/2 u(t)

To find f(t) from the Laplace transform ℋ(f(t)), we need to apply the inverse Laplace transform ℒ⁻¹ to ℋ(f(t)).

Given ℋ(f(t)) = ℋ{s(t)}, we have:

ℒ⁻¹{ℋ(s(t))} = ℒ⁻¹{ℋ[(s + 1)²/s]} = ℒ⁻¹{ℋ[s/s] + ℋ[2s/(s+1)²] + ℋ[1/(s+1)²]}

Using the properties of Laplace transforms and taking the inverse Laplace transforms, we get:

f(t) = u(t) + 2te^(-t) + t^2/2 u(t)

where u(t) is the unit step function.

Therefore, the function f(t) corresponding to the Laplace transform ℋ(f(t)) = ℋ{s(t)} is:

f(t) = u(t) + 2te^(-t) + t^2/2 u(t)

Answers

If  a deadly disease infected the hummingbird population, what would most likely happen to the plants option (b) They would become endangered

If a deadly disease infected the hummingbird population, it would most likely lead to a decrease in the pollination of plants that rely on hummingbirds for pollination. Without the hummingbirds to transfer pollen between flowers, these plants would have a reduced rate of successful pollination, which would result in a decrease in their ability to reproduce.

However, it is unlikely that the plants would die within hours or become endangered immediately, nor would they need to migrate. The effect of the loss of hummingbird pollinators on the plants would depend on the specific plant species, their pollination requirements, and the availability of alternative pollinators. Some plants may be more adaptable to using alternative pollinators, while others may suffer more severe consequences. It is also possible that the loss of hummingbirds could lead to a decline in the populations of other animals that depend on the plants, creating a ripple effect in the ecosystem.

Therefore, the correct option is (d) They would become endangered

an airplane flying with the wind can cover 560 miles in 2 hours. the return trip against the wind takes 2 1 2 hours. what is the speed of the plane? the speed of the plane is miles per hour. what is the speed of the air? the wind's speed is miles per hour.

Answers

The speed of the plane is 252 miles per hour and the speed of the wind is 28 miles per hour .

In the question ,

it is given that ,

the airplane covers the distance of 560 miles in 2 hours with the wind,

So , the speed of the airplane with the wind is 560/2 = 280 miles per hour

also given that

airplane covers the distance of 560 miles in 2.5 hours against the wind ,

So , the speed of the plane with the wind = 560/2.5 = 224 miles per hour .

let the speed of the airplane be "a" miles per hour ,

and let the speed of the wind be "b" miles per hour ,

So , equation of speed  with the wind is denoted by

a + b = 280

and the equation of speed against the wind is denoted by

a - b = 224

Adding both the equations , we get

2a = 504

a = 504/2

a = 252 miles per hour

and b = 280 - 252 = 28 miles per hour .

Therefore , The speed of the plane is 252 miles per hour and the speed of the wind is 28 miles per hour .

Where,

\(\sf T_n\) is the nth term.r is the common ratioa is the first term

According to the given question.

During the first bounce, height of the ball from the ground, a = 4.5 feet

And, the each successive bounce is 73% of the previous bounce's height.

So,

During the second bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 10\)

\(=\dfrac{73}{100}(10)\)

\(\sf = 0.73 \times 10\)

\(\sf = 7.3 \ feet\)

During the third bounce, the height of ball from the ground

\(\sf = 73\% \ of \ 7.3\)

\(=\dfrac{73}{100}(7.3)\)

\(\sf = 5.33 \ feet\)

Like this we will obtain a geometric sequence 7.3, 5.33, 3.11, 2.23,...

And the common ratio of the geometric sequence is 0.73

Therefore,

The sixth term of the geometric sequence is given by

\(\sf T_{10}=10(0.73)^{10-1\)

\(\sf T_{10}=10(0.73)^{9\)

\(\sf T_{10}=10(0.059)\)

What is Tangent Line Approximation?

Tangent line approximation is the approximation of any function using a linear function. It is also called as linear approximation.

It allows us to approximate the value of a general function with a more simpler linear function.

Given that,

f(1) = 2

f'(x) = \(\sqrt{x^{2} +2cos x + 3}\)

We have the formula for linear approximation as,

f(x) = f(a) + f'(a) (x - a)

Here x = 4 and a = 1

f(a) = f(1) = 2

f'(a) = f'(1) = \(\sqrt{1^{2} +2cos 1 + 3}\) = 2.254

Substituting,

f(4) = 2 + (2.254) (4 - 1)

a sample of 137cs (half-life = 30.1 years) decays at a rate of 10^10 decays per second. how long (in years) will it take the decay rate to decrease to 10^7 decays per second?

Answers

It will take 19.44 years for the decay rate of 137Cs to decrease to 10^7 decays per second.

The decay rate of 137Cs is given by the formula:

A = A0 * e^(-λt)

Where A is the decay rate, A0 is the initial decay rate (10^10 decays per second), λ is the decay constant (ln(2)/30.1 years) and t is the time in years.

To calculate the time, t, required for the decay rate to decrease to 10^7 decays per second, we solve for t and substitute the given values into the equation:

\(t = (ln(A0/A))/λ\\t = (ln(10^10/10^7))/(ln(2)/30.1)\\t = 19.44 years\)

Write a system of equations to find the number of World Series championships won by the Yankees, y, and the number of World Series championships won by the Cardinals, x.

Answers

Answer:

1) The system of equations are;

2) y = 27 World Series championships

x = 11 World Series championships

Step-by-step explanation:

1) The number of World Series championships won by the Yankees = y

The second most-winning team = The St. Louis Cardinals

The number of World Series championships won by the St, Louis Cardinals = x

From the details of the number of World Series won by the Yankees and the St. Louis Cardinals we are given, we can write the following system of equations  to find the number of World Series championships won by the Yankees, 'y', and the number of World Series championships won by the Cardinals, 'x' as follows;

y - 2·x = 5...(1)

y + x = 38...(2)

2) Making 'y' the subject of both equations gives;

For equation (1)

y = 5 + 2·x

For equation (2)

y = 38 - x

Equating both 'y' values gives;

y = 5 + 2·x = 38 - x

2·x + x = 38 - 5

3·x = 33

∴ x = 33/3 = 11

The number of World Series championships won by the St, Louis Cardinals, x = 11 World Series championships

From y = 38 - x, we have;

y = 38 - x

∴ y = 38 - 11 = 27

Therefore, the number of World Series championships won by the Yankees, y = 27 World Series championships

(If no, enter " 0 " for the time.) distance Your responwedidfers from the correct answer by more than 10\%, Double chack your calculations, m times ox 5 Need Holp?

Answers

Yes, there will be a collision between Speedy Sue's car and the slow-moving van in the tunnel. The collision will occur at a distance of approximately 146.5 meters into the tunnel, and the time of the collision will be around 7.72 seconds.

To determine whether there will be a collision, we need to calculate the time it takes for Speedy Sue to reach the van and compare it with the time it takes for the van to exit the tunnel.

First, we calculate the time it takes for Sue to reach the van. The relative velocity between Sue and the van is (33.0 m/s - 5.40 m/s) = 27.6 m/s. Using the formula time = distance / velocity, the time it takes for Sue to reach the van is approximately 175 m / 27.6 m/s ≈ 6.34 seconds.

Next, we calculate the time it takes for the van to exit the tunnel. The distance the van needs to travel to exit the tunnel is the sum of the distance from its initial position to the end of the tunnel and the distance Sue needs to travel to reach the end of the tunnel. The total distance is 175 m + 175 m = 350 m. The velocity of the van is 5.40 m/s. Using the formula time = distance / velocity, the time it takes for the van to exit the tunnel is approximately 350 m / 5.40 m/s ≈ 64.81 seconds.

Since 6.34 seconds is less than 64.81 seconds, Sue will collide with the van before it exits the tunnel. To determine the distance into the tunnel where the collision occurs, we subtract the distance Sue travels in 6.34 seconds from the initial distance between Sue and the van. The distance Sue travels is (33.0 m/s - 1.90 m/s^2 * 6.34 s^2 / 2) * 6.34 s ≈ 146.5 meters.

Therefore, the collision between Sue's car and the van will occur at a distance of approximately 146.5 meters into the tunnel, and the time of the collision will be around 7.72 seconds.

Answers

Answer:

Step-by-step explanation:

no because 6 , 7 and 10 doesn't add up to 180 so it is not

A triangle has sides with lengths of 6 kilometers, 7 kilometers, and 10 kilometers is not a right triangle.

To determine if a triangle is a right triangle, you can use the Pythagorean Theorem. The Pythagorean Theorem states that "In a right-angled triangle, the sum of the square of the two shorter sides is equal to the square of the longest side." It can be written as:

a² + b² = c², where 'a' and 'b' are the lengths of the two legs of a right triangle, and 'c' is the length of the hypotenuse.

In this triangle, the two shorter sides have lengths of 6 kilometers and 7 kilometers and the longest side is 10 kilometers.

The square of 6 kilometers is 36 kilometers and the square of 7 kilometers is 49 kilometers.

The sum of 36 kilometers and 49 kilometers is 85 kilometers.

The longest side of the triangle has a length of 10 kilometers, and the square of 10 kilometers is 100 kilometers.

Since 85 kilometers is not equal to 100 kilometers, this triangle is not a right triangle.

Use the following information to answer the question. The distribution of the number of hours of sleep people get per night is unimodal and symmetric with a mean of 6 hours and a standard deviation of 1.5 hours.Approximately what percent of people sleep between 6 and 7.5 hours per night?

Answers

Approximately 34 percent of people sleep between 6 and 7.5 hours per night.

Since the distribution is symmetric, we know that the percentage of people who sleep between 6 and 7.5 hours per night is approximately half of the total percentage of people who sleep within one standard deviation of the mean.

One standard deviation from the mean in either direction is 1.5 hours, so the percentage of people who sleep between 4.5 and 7.5 hours per night is approximately 68%. Therefore, approximately half of 68%, or 34%, of people sleep between 6 and 7.5 hours per night.

In this case, we want to find the percentage of people who sleep between 6 and 7.5 hours per night. Since the mean is 6 hours and the standard deviation is 1.5 hours, one standard deviation above the mean is 6 + 1.5 = 7.5 hours. Therefore, according to the Empirical Rule, approximately 34% of people sleep between 6 and 7.5 hours per night.

It is assumed that approximately 15% of adults in the US. are left-handed. Consider the probability that among 100 adults selected in the U.S., there are at least 30 who are left-handed. Given that the adults surveyed were selected without replacement, can the probability be found by using the binomial probability formula with x counting the number who are left-handed? Why or why not? Choose the correct answer below ○ A. O B. Yes, because the 100 adults represent less than 5% of the U.S. adult population, the trials can be treated as independent. No, because the 30 adults represent more than 5% of the sample size, the trials are dependent No, because the 100 adults were selected without replacement, the selections are dependent. No, because the probability of being right-handed is greater, x must count the number of right-handed adults. C. O D.

Answers

D. No, because the probability of being left-handed is greater, x must count the number of left-handed adults.

The binomial probability formula can be used to calculate the probability of a certain number of successes (or left-handed individuals) in a given number of trials (100 adults). In order for the binomial probability formula to be used, the trials must be independent, meaning that the selection of one person does not affect the selection of the next one. Since the probability of being left-handed is greater, the binomial probability formula cannot be used in this case and x must count the number of left-handed adults.
