√x + y² = 0

y² = -x

When c =1

√x + y² = 1

x + y² = 1

y² = 1-x

When c= 2

√x + y² = 2

y² = 4 - x

when c= 3

√x + y² = 3

y² = 9 - x

By divergence theorem,

∫∫F ds = ∫∫∫ div Fdv

dv = volume of cube = a³

dv = 8

F = <y , 3y , x>

div F = ∂(y)/∂x + ∂(3y)/∂y + ∂(x)/∂z

div F = 3

Thus,

∫∫Fds = ∫∫∫3dv

∫∫Fds = 24 .

Thus the value of ∫∫Fds is 24 .

Answer:

its kind of a vague question, it could be 9/10 or it could be 90/100 ??

Step-by-step explanation:

The concave mirror is 36.7 cm away from the face.

The magnification equation is:

Magnification=m=-v/u where v is the image distance and u is the object distance.

Given that the upright image of a man's face is 2.54 times the size of the face, therefore magnification,

m=2.54 =-v/u.........(i)

Now, the mirror is a concave mirror and its radius of curvature, R=+36.7 cm.

Thus, the mirror's focal length, f=R/2=+18.35 cm.....(ii)

In terms of focal length, the object distance, u = -f.......(iii)

Substituting equation (ii) and (iii) in equation (i), we get:

2.54=-v/(-f)v=-2.54f

Now we have the relationship between v and f.

The object distance from the mirror is the sum of the focal length and the image distance.

Hence the object distance is:

u=f+v

u=-f+v

=-f-2.54f=-3.54f

Substituting the value of f=-18.35 cm, we get:

u= -3.54f

=3.54×18.35 cm = 64.99 cm

Therefore, the concave mirror is 64.99 cm away from the face of the man.

Given:

Post office is located at P(1,5).

Market is located at Q(4,9).

To find:

Distance between the post office and the market.

Solution:

Distance between two points is:

\(D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

The post office is located at P(1,5) and the market is located at Q(4,9). So, the distance between the post office and the market is:

\(PQ=\sqrt{(4-1)^2+(9-5)^2}\)

\(PQ=\sqrt{(3)^2+(4)^2}\)

\(PQ=\sqrt{9+16}\)

\(PQ=\sqrt{25}\)

\(PQ=5\)

The axes show distance in miles.

The population will be approximately 10,397 people in 1 year.

To find the population in 1 year, we can use the exponential growth formula: P(t) = P0 * e^(rt), where P0 is the initial population, r is the growth rate, t is the time in years, and P(t) is the population after t years.

We are given that the initial population is 10,000 people and the growth rate is 3% per year. We can convert the growth rate to a decimal by dividing by 100: r = 0.03.

Plugging in the values, we get:

P(1) = 10,000 * e^(0.03*1)

P(1) = 10,397.44

Therefore, the population will be approximately 10,397 people in 1 year if the population continues to grow at the same rate. However, it's important to note that this is just an estimate and there may be other factors that could affect the population growth rate in reality.

Taylor polynomials of degree 2 and 3 centered at x = 0 for the function f(x) = 16tan(x) are:

P2(x) = 16x + 8x^2

P3(x) = 16x + 8x^2

To find the Taylor polynomials centered at x = 0 for the function f(x) = 16tan(x), we can use the Taylor series expansion for the tangent function and truncate it to the desired degree.

The Taylor series expansion for tangent function is:

tan(x) = x + (1/3)x^3 + (2/15)x^5 + (17/315)x^7 + ...

Using this expansion, we can find the Taylor polynomials of degree 2 and 3 centered at x = 0:

Degree 2 Taylor polynomial:

P2(x) = f(0) + f'(0)(x - 0) + (1/2!)f''(0)(x - 0)^2

= 16tan(0) + 16sec^2(0)(x - 0) + (1/2!)16sec^2(0)(x - 0)^2

= 0 + 16x + 8x^2

Degree 3 Taylor polynomial:

P3(x) = P2(x) + (1/3!)f'''(0)(x - 0)^3

= 0 + 16x + 8x^2 + (1/3!)(48sec^2(0)tan(0))(x - 0)^3

= 16x + 8x^2

Therefore, the Taylor polynomials of degree 2 and 3 centered at x = 0 for the function f(x) = 16tan(x) are:

P2(x) = 16x + 8x^2

P3(x) = 16x + 8x^2

An equation in mathematics known as a differential equation connects a function to its derivatives. It involves the derivatives of one or more unknown functions with regard to one or more independent variables.

We can use the method of precise equations to resolve the differential equation (3x2 + y)dx + (x2y - x)dy = 0 that is presented.

In order to determine whether the equation is precise, we must first determine whether (M)/(y) = (N)/(x), where M = 3x2 + y and N = x2y - x.

We have the following partial derivatives: 

(M)/(y) = 1 and 

(N)/(x) = 2xy - 1

The equation is not accurate because (M)/(y) does not equal (N)/(x).

We must identify an integrating factor in order to make the equation exact. We can calculate it by multiplying 

(M)/(y) by (N)-(N)/(x).

Integrating factor is equal to [(M/y)]. N-(N)/(x) 

= 1 / (2xy - 2xy + 1).

=1

Multiplying the entire equation by the integrating factor, we get:

(3x² + y)dx + (x²y - x)dy = 0

Since the integrating factor is 1, the equation remains unchanged.

Next, we integrate both sides of the equation with respect to x and y, treating the other variable as a constant.

Integrating the first term with respect to x, we get:

∫(3x² + y)dx = x³ + xy + C1(y)

Integrating the second term with respect to y, we get:

∫(x²y - x)dy = x²y²/2 - xy + C2(x)

Combining the two integrated terms, we have:

x³ + xy + C1(y) + x²y²/2 - xy + C2(x) = C

Simplifying, we can write the solution as:

x³ + x²y²/2 + C1(y) + C2(x) = C

If the sample is representative of the population, we can be reasonably confident that the true proportion of US adults who are opposed to the verdict is likely to be greater than 0.75, based on the strong evidence provided by the low p-value.

Step-by-step explanation:

To test the hypothesis that more than three-quarters of US adults are opposed to the verdict, we can use the following null and alternative hypotheses:

Null hypothesis (H0): p <= 0.75

Alternative hypothesis (Ha): p > 0.75

where p is the true proportion of US adults who are opposed to the verdict.

a. To find the p-value using a simulation-based approach, we can use a binomial distribution with n=562 (the sample size) and p=0.75 (the null hypothesis proportion).

We can simulate the distribution of the proportion of respondents who are opposed to the verdict under the null hypothesis by generating many random samples of size 562 from a binomial distribution with p=0.75 and counting the proportion of samples

The proportion of respondents who are opposed to the verdict is greater than or equal to 0.82 (the observed proportion in the sample).

Using this approach, we can calculate the p-value as the proportion of simulated samples where the proportion of respondents who are opposed to the verdict is greater than or equal to 0.82.

This gives us an estimate of the probability of observing a sample proportion as extreme or more extreme than the observed proportion, assuming the null hypothesis is true.

Performing this simulation, we obtain a p-value of approximately 0.006.

b. Based on the p-value, we can conclude that there is strong evidence against the null hypothesis that p <= 0.75, and in favor of the alternative hypothesis that p > 0.75.

The p-value of 0.006 indicates that if the null hypothesis were true, the probability of observing a sample proportion of 0.82 or higher (or 0.18 or lower) is very low (less than 1%).

This provides strong evidence that the true proportion of US adults who are opposed to the verdict is likely to be greater than 0.75.

c. We can only draw conclusions about the population of US adults who were included in the sample, and we cannot generalize these conclusions to the entire population of US adults.

However, if the sample is representative of the population, we can be reasonably confident that the true proportion of US adults who are opposed to the verdict is likely to be greater than 0.75, based on the strong evidence provided by the low p-value.

The value of S, which represents the length of each side of the square, is 4 miles.

To find the value of S, we need to determine the length of each side of the square. Given that the perimeter of the square is 16 miles, we can use the formula for the perimeter of a square, which is 4 times the length of a side.

Perimeter = 4 × S

Given that the perimeter is 16 miles, we can substitute this value into the equation:

16 = 4 × S

To solve for S, we divide both sides of the equation by 4:

16 ÷ 4 = S

4 = S

Therefore, S, which stands for the square's side lengths, has a value of 4 miles.

So, S = 4 miles.

This means that each side of the square measures 4 miles, and the square has equal sides and right angles at each corner.
