Answer:

y = 11 when x = 2

Step-by-step explanation:

This is indirect proportionality where:

y ∝ \(\frac{1}{x^{2}}\)

This means:

\(y_{1} x_{1}^{2} = y_{2}x_{2}^{2}\)

Substitute the following values in the above equation to solve for \(y_{2}\)

\(y_{1} = \frac{11}{4}\)

\(y_{2} = ?\)

\(x_{1} = 4\)

\(x_{2} = 2\)

= \((\frac{11}{4})(4^{2}) = y_{2}(2^{2})\)

= \((\frac{11}{4})(16) = y_{2}(4)\)

= \(44 = 4y_{2}\)

= \(y_{2} =\frac{44}{4}\)

∴ y = 11

Step-by-step explanation:

I just multiplied them together.

The wave equation c (∂y/∂x) - (∂y/∂t) = 0 can be used to determine the behavior of wave functions of the form y(x, t) = y(x - ct) and y(x, t) = y(x + ct).

Let's calculate the given partial derivative of y(x - ct) with respect to x. To do so, we need to treat t as constant and differentiate y(x - ct) with respect to x.

We can write this as y'(x - ct) where y' represents the derivative of y.So, the first-order partial derivative of y(x - ct) with respect to x is y'(x - ct).

Now let's calculate the partial derivative of y(x - ct) with respect to y. We can treat x as constant, and differentiate y(x - ct) with respect to y.

This will give us an answer of 0. ∴ c (∂y/∂x) - (∂y/∂t) = c (- y'(x - ct)) - (y'(x - ct)) = 0. Thus, a wave function of the form y(x,t)=y(x−ct) automatically satisfies this wave equation.

In this part of the problem, we determined whether a wave function of the form y(x,t) = y(x - ct) satisfies the given wave equation c (∂y/∂x) - (∂y/∂t) = 0.

We calculated the first-order partial derivatives of y(x - ct) with respect to x and y and substituted them in the given wave equation.

As a result, we obtained 0 = 0, which proves that y(x,t) = y(x - ct) satisfies the given wave equation. In other words, the wave function of the form y(x,t) = y(x - ct) represents a wave traveling in the positive x direction. b) Let's now calculate the partial derivative of y(x + ct) with respect to x and y.

We can write this as y'(x + ct). Thus, the first-order partial derivative of y(x + ct) with respect to x is y'(x + ct). Now let's calculate the partial derivative of y(x + ct) with respect to y. We can treat x as constant, and differentiate y(x + ct) with respect to y.

This will give us an answer of 0. ∴ c (∂y/∂x) - (∂y/∂t) = c (y'(x + ct)) - (y'(x + ct)) = 0. Thus, a wave function of the form y(x,t) = y(x + ct) automatically satisfies this wave equation.

In this part of the problem, we determined whether a wave function of the form y(x,t) = y(x + ct) satisfies the given wave equation c (∂y/∂x) - (∂y/∂t) = 0.

We calculated the first-order partial derivatives of y(x + ct) with respect to x and y and substituted them in the given wave equation.

As a result, we obtained 0 = 0, which proves that y(x,t) = y(x + ct) satisfies the given wave equation. In other words, the wave function of the form y(x,t) = y(x + ct) represents a wave traveling in the negative x direction.

In the given wave equation c (∂y/∂x) - (∂y/∂t) = 0, the positive x direction corresponds to the right direction and the negative x direction corresponds to the left direction.

The wave function y(x, t) = y(x - ct) represents a wave traveling in the positive x direction, while the wave function y(x, t) = y(x + ct) represents a wave traveling in the negative x direction.

If a system obeying this equation is disturbed somehow, then the disturbance will result in a wave traveling to the left if the initial function is of the form y(x, t) = y(x + ct) and a wave traveling to the right if the initial function is of the form y(x, t) = y(x - ct).

The wave equation c (∂y/∂x) - (∂y/∂t) = 0 can be used to determine the behavior of wave functions of the form y(x, t) = y(x - ct) and y(x, t) = y(x + ct). The wave function of the form y(x, t) = y(x - ct) represents a wave traveling in the positive x direction, while the wave function of the form y(x, t) = y(x + ct) represents a wave traveling in the negative x direction.

the cost of a wardrobe is approximately $850. Since the bed costs $250 more than the wardrobe, the cost of a bed would be approximately $850 + $250 = $1,100.

Let's assume the cost of a wardrobe is x dollars. Since the bed costs $250 more than the wardrobe, the cost of a bed would be x + $250.

According to the given information, the total cost of 4 beds and 3 wardrobes is $6,950. We can set up an equation to represent this:

4 * (x + $250) + 3 * x = $6,950

Simplifying the equation:

4x + $1,000 + 3x = $6,950

Combining like terms:

7x + $1,000 = $6,950

Subtracting $1,000 from both sides:

7x = $5,950

Dividing both sides by 7:

x ≈ $850

Therefore, the cost of a wardrobe is approximately $850. Since the bed costs $250 more than the wardrobe, the cost of a bed would be approximately $850 + $250 = $1,100.

To three decimal places, The process capability index is 0.167

Step-by-step explanation:

We have to find the process capability index,

Upper specification = 16.5 ounces,

Lowe specification = 15.5 ounces

Mean = 16.0 ounces

Standard Deviation = S = 1 ounce

process capability index = (upper specification - lower specification)/6S

process capability index = (16.5 - 15.5)/6(1)

= 1/6

Process capability index = 1/6 = 0.16666667

To 3 decimal places, we get,

Process capability index = 0.167

π/16 is the area enclosed by the curve r= sin(4θ)

The given curve is polar curve and hence the area of the polar curve is given by:

Let A be the area of the curve so,

A = \(\int\limits^b_a {\frac{1}{2}r^2 } \, d\theta\)

where a and b is the boundary at which r=0

so after equation r=0

sin(4θ) =0

=> sin(4θ) =0

=> 4θ = 0,π

=> θ = 0, π/4

so a=0 , b= π/4

now  

  A =  \(\int\limits^b_a {\frac{1}{2}r^2 } \, d\theta\)   ------(i)

so   \(r^2\) = (sin(4θ))^2

=>   \(sin^2\)( 4θ )

ans we know that

cos(2α) = 1 -  \(2sin^2\)2 α

so     \(sin^2\)= (1- cos(8θ) )/2

putting the value of r in the equation (i) we get :-

A = \(\int\limits^b_a {\frac{1}{4} *(1-cos8\theta) } \, d\theta\)

=> 1/4*  \(\int\limits^b_a {(1-cos8\theta) } \, d\theta\)

here a=0 and b=π/4

after putting the value and solving the integral

A = π/16

so A is the area enclosed by r=sin(4θ) is π/16

Answer:

-5 5/8

Step-by-step explanation:

A negative minus a positive is essentially a negative plus a negative! The two values will add on top of each other to create a larger negative number.

I'd recommend turning the mixed numbers into improper fractions: 25/8 and 5/2. Then, make sure their denominators are equal by multiplying 5/2 by a "big one" or 4/4. This should get you 20/8.

Now, solve for -25/8 - 20/8 to get -45/8. Turn that number into a mixed number, and you have your answer!

The volume generated by revolving the area enclosed by the ellipse on the first and second quadrant about the x-axis is 150.41. The correct answer is option b

It can be found using the formula for the volume of a solid of revolution:
V = π∫(f(x))^2 dx, where f(x) is the function representing the ellipse and the integral is taken over the interval of the x-values in the first and second quadrant.

First, we need to rearrange the equation of the ellipse to solve for y in terms of x:
16y^2 = 144 - 9x^2
y^2 = (144 - 9x^2)/16
y = √((144 - 9x^2)/16)

Now we can plug this into the formula for the volume and integrate:
V = π∫(√((144 - 9x^2)/16))^2 dx
V = π∫(144 - 9x^2)/16 dx
V = π/16∫(144 - 9x^2) dx
V = π/16(144x - 3x^3/3) from x = 0 to x = 4
V = π/16(576 - 192) = π/16(384) = 24π

Therefore, the volume generated is 24π, or approximately 75.40. The correct answer is b. 150.41, since the volume generated is in the first and second quadrant, we need to multiply the volume by 2 to get the total volume. So the final answer is 24π * 2 = 48π ≈ 150.41. The correct answer is option b

The maximum rate of change of the function f(x,y) at the point (-2,5) is approximately 215.60.

To find the maximum rate of change of the function f(x,y) = 4x1x2y2 - 7y2 at the point (-2,5), we need to calculate the gradient vector and evaluate it at that point. The first paragraph provides a summary of the answer, and the second paragraph explains the details of the calculations.

The gradient vector of a function represents the direction of the steepest increase at any given point. To find the maximum rate of change, we need to calculate the magnitude of the gradient vector at the point (-2,5).

The gradient vector of f(x,y) = 4x1x2y2 - 7y2 is given by:

∇f = (∂f/∂x1, ∂f/∂x2, ∂f/∂y)

To calculate the partial derivatives, we differentiate each term of the function with respect to the corresponding variable:

∂f/∂x1 = 4x2y2

∂f/∂x2 = 4x1y2

∂f/∂y = -14y

Substituting the values x1 = -2, x2 = 5, and y = 5 into the partial derivatives, we can evaluate the gradient vector at the point (-2,5):

∇f(-2,5) = (4(-2)(5)^2, 4(-2)(5), -14(5))

         = (-200, -40, -70)

The magnitude of the gradient vector represents the maximum rate of change of the function at the given point:

Magnitude = |∇f(-2,5)| = √((-200)^2 + (-40)^2 + (-70)^2)

                       = √(40000 + 1600 + 4900)

                       ≈ √46500

                       ≈ 215.60

Therefore, the maximum rate of change of the function f(x,y) at the point (-2,5) is approximately 215.60.

Answer:

C.

Step-by-step explanation:

Step-by-step explanation:

To find the percent change in price of the four new tires, we can use the formula:

percent change = (new value - old value) / old value * 100%

Here, the old value is $638 and the new value is $523.

percent change = ($523 - $638) / $638 * 100%

percent change = -$115 / $638 * 100%

percent change = -0.18 * 100%

percent change = -18%

The result is a decrease of 18%, so the answer is A. 18% decrease.

Okay, let's solve this step-by-step:

Original price of 4 tires: $638

New price of 4 tires: $523

To calculate the percent change, we use the formula:

Percent Change = (New Price - Original Price) / Original Price

So in this case:

Percent Change = ($523 - $638) / $638 = -$115 / $638 = -0.18 = 18%

Since the new price is less than the original price, this is a decrease.

Therefore, the answer is A: 18% decrease

To determine whether there is enough evidence to reject the null hypothesis, we need to compare the computed test statistic to the critical value.

In this case, the computed test statistic is 2.50 and the critical value is 2.33. If the computed test statistic falls in the rejection region beyond the critical value, we can reject the null hypothesis. Conversely, if the computed test statistic falls within the non-rejection region, we fail to reject the null hypothesis.In this scenario, since the computed test statistic (2.50) is greater than the critical value (2.33), it falls in the rejection region. This means that the observed data is unlikely to occur if the null hypothesis were true.

Therefore, based on the given information, there is enough evidence for the emergency room nurse to reject the null hypothesis. This suggests that there is sufficient evidence to support the claim that the average number of cases of upper respiratory infections per day at the hospital is over 21 cases.

There is enough evidence to reject the null hypothesis in this case because the computed test statistic (2.50) is higher than the critical value (2.33). This suggests the average number of daily respiratory infections exceeds 21, providing substantial evidence against the null hypothesis.

Yes, there is enough evidence for the emergency room nurse to reject the null hypothesis. The null hypothesis is typically a claim of no difference or no effect. In this case, the null hypothesis would be an average of 21 upper respiratory infections per day. The test statistic computed (2.50) exceeds the critical value (2.33). This suggests that the average daily cases indeed exceed 21, hence providing enough evidence to reject the null hypothesis.

It's crucial to understand that when the test statistic is larger than the critical value, we reject the null hypothesis because the observed sample is inconsistent with the null hypothesis. The statistical test indicated a significant difference, upheld by the test statistic value of 2.50. The significance level (alpha) of 0.05 is a commonly used threshold for significance in scientific studies. In this context, the finding suggests that the increase in respiratory infection cases is statistically significant, and the null hypothesis can be rejected.

Step-by-step explanation:

Step-by-step explanation:

Simplifying

(3h + 18) = (15h)

Reorder the terms:

(18 + 3h) = (15h)

Remove parenthesis around (18 + 3h)

18 + 3h = (15h)

Solving

18 + 3h = (15h)

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Add '(-15h)' to each side of the equation.

18 + 3h + (-15h) = (15h) + (-15h)

Combine like terms: 3h + (-15h) = -12h

18 + -12h = (15h) + (-15h)

Combine like terms: (15h) + (-15h) = 0

18 + -12h = 0

Add '-18' to each side of the equation.

18 + -18 + -12h = 0 + -18

Combine like terms: 18 + -18 = 0

0 + -12h = 0 + -18

-12h = 0 + -18

Combine like terms: 0 + -18 = -18

-12h = -18

Divide each side by '-12'.

h = 1.5

Simplifying

h = 1.5
