Answer:

Step-by-step explanation:

9 = - 7w + 12w - 6

by transposing,

9 + 6 = -7w + 12w

15 = 5w

w = 15 / 5

w = 3

Hope this helps

plz mark as brainliest!!!!!!

Answer:

\(w=3\)

Step-by-step explanation:

\(9 = -7w + 12w -6\)

Start by combining like terms (\(-7w+12w\)):

\(9=5w-6\)

Add \(6\) to both sides of the equation:

\(15=5w\)

Divide both sides of the equation by the coefficient of \(w\), which is \(5\):

\(3=w\)

_

Check your work by substituting the solved value of \(w\) (\(3\)), into the initial equation:

\(9 = -7(3) + 12(3) -6\)

Multiply:

\(9=-21+36-6\)

Combine like terms:

\(9=9\)

Since both sides of the equation are equal, our answer is correct!

Average speed of train B is 60 mph.

To find average speed of train B:

Let average speed of train B = x mph.

Based on information provided to us it is said average speed of train A is 20 mph more than B.

Average speed of train A = (x + 20) mph.

Speed = Distance/ Time

The time taken by both trains will be the same since they cover their respective distances in the same time.

For train A:

Speed of train A = (x + 20) mph

Distance covered by train A = 240 miles

Time taken by train A = Distance / Speed = 240 / (x + 20) hours

For train B:

Speed of train B = x mph

Distance covered by train B = 180 miles

Time taken by train B = Distance / Speed = 180 / x hours

Since the time taken by both trains is the same, we can set up an equation:

240 / (x + 20) = 180 / x

240x = 180(x + 20)

240x = 180x + 3600

240x - 180x = 3600

60x = 3600

x = 3600 / 60

x = 60

Therefore, the average speed of train B is 60 mph.

The expression \(du^2 = (dx)^2 + (dy)^2\) in polar coordinates can be derived using the given transformations u = f(x, y), x = r cos θ, and y = r sin θ.

In the given problem, we have u = f(x, y) and the transformations x = r cos θ and y = r sin θ, where r and θ represent the polar coordinates. We need to find the expression for \(du^2\).

Using the chain rule, we can express the differentials dx and dy in terms of dr and dθ:

dx = dr cos θ - r sin θ dθ,

dy = dr sin θ + r cos θ dθ.

Substituting these into the expression \(du^2 = (dx)^2 + (dy)^2\), we get:

\(\[du^2 = \left(dr \cos \theta - r \sin \theta d\theta\right)^2 + \left(dr \sin \theta + r \cos \theta d\theta\right)^2\]\).

Expanding and simplifying the above expression, we obtain:

\(\[ du^2 = (dr)^2 + r^2 (d\theta)^2 \]\).

This is the desired expression for \(du^2\) in polar coordinates.

Moving on to the second part of the question, we are asked to evaluate ∫∫fx dx dy over the region bounded by y = x² and y = x³.

Converting the integral into polar coordinates, we need to determine the limits of integration. From the given equations y = x² and y = x³, we can find the intersections by solving x² = x³, which gives x = 0 and x = 1.

In polar coordinates, x = r cos θ and y = r sin θ. We need to find the values of r and θ that correspond to the points of intersection.

For x = 0, we have r cos θ = 0, which implies θ = π/2 or θ = 3π/2.

For x = 1, we have r cos θ = 1, which implies r = 1/cos θ.

Therefore, the limits of integration for r are from 0 to 1/cos θ, and for θ, they are from π/2 to 3π/2.

Finally, we can evaluate the integral ∫∫fx dx dy by converting it to polar coordinates and applying the limits of integration found above.

Over a short interval near time t=0, the coordinate of an automobile is given by x(1) = 30t² − 15t³. At the end of 1.0 s the automobile is deaccelerating (option C). The muon takes 0.100 m to stop (option E).

Given that x(1) = 30t² − 15t³

The velocity of the automobile is given by:

v = dx/dtv = 60t − 45t²

When the time t = 1.0 s, we have: v = 60(1.0) − 45(1.0)²= 15 m/s

Since the velocity is positive, the automobile is moving to the right (i.e. accelerating).

However, since the velocity is decreasing, the automobile is deaccelerating. To determine the acceleration, we take the derivative of the velocity with respect to time:

a = dv/dta = 60 − 90t

When t = 1.0 s, a = 60 − 90(1.0)= −30 m/s²

Since the acceleration is negative, the automobile is deaccelerating (option C).

5. The initial velocity, u = 8.00×10⁵ m/s

The acceleration, a = -3.20×10¹⁴ m/s² (since the muon is slowed down)

Final velocity, v = 0

We want to find the distance traveled, s.

To find the distance traveled, we use:

s = (v² − u²)/2a

Here, u = 8.00×10⁵ m/s,

v = 0, and

a = -3.20×10¹⁴ m/s²

So,s = (0 − (8.00×10⁵)²)/2(−3.20×10¹⁴)= 0.100 m

Therefore, the muon takes 0.100 m to stop (option E).

The sample variance for the given data is 4.4 minutes. This corresponds to option e. in the list of choices provided.

The sample variance is a measure of how much the individual data points in a sample vary from the mean.

It is calculated by finding the average of the squared differences between each data point and the mean.

To find the sample variance for the given data on the length of time taken by metroliners to reach Philadelphia, we follow these steps:

Calculate the mean (average) of the data set:

Mean = (93 + 89 + 91 + 87 + 91 + 89) / 6 = 540 / 6 = 90

Subtract the mean from each data point and square the result:

(93 - 90)^2 = 9

(89 - 90)^2 = 1

(91 - 90)^2 = 1

(87 - 90)^2 = 9

(91 - 90)^2 = 1

(89 - 90)^2 = 1

Calculate the sum of the squared differences:

9 + 1 + 1 + 9 + 1 + 1 = 22

Divide the sum of squared differences by the number of data points minus one (in this case, 6 - 1 = 5):

Variance = 22 / 5 = 4.4

Answer:

To solve this problem, we can use the formula for exponential growth:

N = N0 * (1 + r)^t

Where:

N0 = the initial population size

N = the population size after t time periods

r = the growth rate per time period

t = the number of time periods

In this case, we know that the initial population (N0) is 6000, the growth rate (r) is 15% per day, and we want to find the population size (N) after 10 days (t = 10).

First, we need to convert the growth rate from a percentage to a decimal:

r = 15% / 100% = 0.15

Now we can plug in the values and solve for N:

N = 6000 * (1 + 0.15)^10

N = 6000 * 3.439

N ≈ 20,634

Therefore, the population of bacteria after 10 days would be approximately 20,634.

This is because the researcher is likely to experience fatigue over the course of the trials, so the number of squeezes should not significantly increase after the tenth trial.

Fatigue is a normal physiological response to physical activity and can affect performance, resulting in decreased strength, power, and endurance. The researcher is likely to become increasingly tired and less able to squeeze the bulb during each successive trial, so the 11th trial should not show any significant increases in the number of squeezes compared to the previous trials.
