The total distance travelled by the particle from t=1 to t=4 is 98 feet.

1) We can find velocity by taking the derivative of position i.e. s'(t)=15. It means that the particle is moving with a constant velocity of 15 ft/s when acceleration is zero.2) The particle is moving in the positive direction if its velocity is positive i.e. s'(t)>0. Similarly, the particle is moving in the negative direction if its velocity is negative i.e. s'(t)<0.Using s'(t)=15, we can see that the particle is always moving in the positive direction.3) We have to find all the local (relative) extrema of the position function. Using s(t)=15t-2, we can calculate the first derivative as s'(t)=15. The derivative of s'(t) is zero which shows that there are no local extrema on the given interval.4) The given function is s(t)=15t-2. We need to find the integral of s(u) from t=1 to t=4. Using the integration formula, we can calculate the integral as:S(t)=∫s(u)du=t(15t-2)dt= 15/2 t^2 - 2t + C Putting the limits of integration and simplifying.

The area between the birth rate and death rate curves over the interval [0, 10] is 5478.38 (rounded to two decimal places).

To find the area between the curves of the birth rate function and the death rate function over a given interval, we need to calculate the definite integral of the difference between the two functions. In this case, we'll integrate the expression b(t) - d(t) over the interval [0, 10].

The birth rate function is given as b(t) = 2500e^(0.023t) people per year,

and the death rate function is given as d(t) = 1430e^(0.019t) people per year.

To find the area between the curves, we can evaluate the definite integral:

Area = ∫[0, 10] (b(t) - d(t)) dt

= ∫[0, 10] (2500e^(0.023t) - 1430e^(0.019t)) dt

To compute this integral, we can use numerical methods or software. Let's use a numerical approximation with a calculator or software:

Area ≈ 5478.38

Therefore, the approximate area between the birth rate and death rate curves over the interval [0, 10] is 5478.38 (rounded to two decimal places).

The line integral R is evaluated by splitting it into two components: Scy'd.r and rdy. The first component is calculated using the parametric equations of the parabola, while the second component simplifies to the integral of ydy over the given range.

To evaluate the line integral R, we need to calculate the two components separately and then sum them. Let's start with the first component, Scy'd.r. Since the line integral is defined along the arc of the parabola r = 4 - y², we can express the parabola parametrically as x = y and z = 4 - y². We then calculate the differential of position vector dr = dx i + dy j + dz k, which simplifies to dy j + (-2y dy) k. Taking the dot product of Scy'd.r, we have S c(y dy) . (dy j + (-2y dy) k). Integrating this expression over the given range (-5, -3) to (0, 2), we obtain the first component of the line integral.

Moving on to the second component, rdy, we simply integrate ydy over the same range (-5, -3) to (0, 2). This integral evaluates to the sum of the antiderivative of y²/2 evaluated at the upper and lower limits.

After calculating both components, we add them together to obtain the final value of the line integral R.

the correct option is option d): ∫(x² cos(3x)) dx = (x/3 + 1/27) * sin(3x) + C. To solve the integral ∫(x² cos(3x)) dx, we can use integration by parts.

Let's use the following formula for integration by parts:

∫(u * v) dx = u * ∫v dx - ∫(u' * ∫v dx) dx,

where u' is the derivative of u with respect to x.

In this case, let's choose:

u = x² => u' = 2x,

v = sin(3x) => ∫v dx = -cos(3x)/3.

Now, applying the formula:

∫(x² cos(3x)) dx = x² * (-cos(3x)/3) - ∫(2x * (-cos(3x)/3)) dx.

Simplifying:

∫(x² cos(3x)) dx = -x² * cos(3x)/3 + 2/3 * ∫(x * cos(3x)) dx.

Now, we have a new integral to solve: ∫(x * cos(3x)) dx.

Applying integration by parts again:

Let's choose:

u = x => u' = 1,

v = (1/3)sin(3x) => ∫v dx = (-1/9)cos(3x).

∫(x * cos(3x)) dx = x * ((1/3)sin(3x)) - ∫(1 * ((-1/9)cos(3x))) dx.

Simplifying:

∫(x * cos(3x)) dx = (x/3) * sin(3x) + (1/9) * ∫cos(3x) dx.

The integral of cos(3x) can be easily found:

∫cos(3x) dx = (1/3)sin(3x).

Now, substituting this back into the previous expression:

∫(x * cos(3x)) dx = (x/3) * sin(3x) + (1/9) * ((1/3)sin(3x)) + C.

Simplifying further:

∫(x * cos(3x)) dx = (x/3) * sin(3x) + (1/27) * sin(3x) + C.

Combining the terms:

∫(x * cos(3x)) dx = (x/3 + 1/27) * sin(3x) + C.

Therefore, the correct option is option d):

∫(x² cos(3x)) dx = (x/3 + 1/27) * sin(3x) + C.

The definite integral of f(x) from 5 to -1 is -1.5 units. The average value of f(x) on the interval [-1, 5] is 0.75.

To evaluate the definite integral ∫[5, -1] f(x)dx, we need to split the interval into two parts: [-1, 1] and [1, 5]. In the interval [-1, 1], f(x) = x, and in the interval [1, 5], f(x) = 1/x.

Integrating f(x) = x in the interval [-1, 1], we get ∫[-1, 1] x dx = [x^2/2] from -1 to 1 = (1/2) - (-1/2) = 1.

Integrating f(x) = 1/x in the interval [1, 5], we get ∫[1, 5] 1/x dx = [ln|x|] from 1 to 5 = ln(5) - ln(1) = ln(5).

Therefore, the definite integral ∫[5, -1] f(x)dx = 1 + ln(5) ≈ -1.5 units.

To evaluate the average value of f(x) on the interval [-1, 5], we divide the definite integral by the length of the interval: (1 + ln(5)) / (5 - (-1)) = (1 + ln(5)) / 6 ≈ 0.75.

the equation of the normal plane to the curve at the point (0, 1, 3) is 2x + 6z - 18 = 0.

To find the equation of the normal plane, we first calculate the gradient vector of the curve at the given point. The gradient vector is obtained by taking the partial derivatives of the curve with respect to each variable: ∇r = (dx/dt, dy/dt, dz/dt) = (2cos(2t), 2sin(2t), 6).

At the point (0, 1, 3), the parameter t is 0. Therefore, the gradient vector at this point becomes ∇r = (2cos(0), 2sin(0), 6) = (2, 0, 6).

The normal vector of the plane is the same as the gradient vector, so the normal vector is (2, 0, 6). Since the normal vector represents the coefficients of x, y, and z in the equation of the plane, the equation of the normal plane becomes:

2(x - 0) + 0(y - 1) + 6(z - 3) = 0.

A random sample of 100 observations from a normal population has a sample variance of 220. We need to test, with a significance level of α = 0.05, whether we can infer that the population variance differs from 300.

To test whether the population variance differs from a hypothesized value of 300, we can use the chi-square test. In this case, we calculate the test statistic as (n-1)s^2/σ^2, where n is the sample size, s^2 is the sample variance, and σ^2 is the hypothesized population variance.

In our case, the sample variance is 220, and the hypothesized population variance is 300. The sample size is 100. Thus, the test statistic is (100-1)*220/300.

We can compare this test statistic to the critical value from the chi-square distribution with degrees of freedom equal to n-1. With a significance level of α = 0.05, we find the critical value from the chi-square distribution table.

If the test statistic is greater than the critical value, we reject the null hypothesis that the population variance is 300, indicating that there is evidence that the population variance differs from 300. Conversely, if the test statistic is less than or equal to the critical value, we fail to reject the null hypothesis and do not have enough evidence to conclude that the population variance is different from 300.

In conclusion, by comparing the calculated test statistic to the critical value, we can determine whether we can infer that the population variance differs from the hypothesized value of 300, with a significance level of α = 0.05.

Naron is three times older than his sister, which means his age is 3X.

Let's assume that the age of Naron's sister is X years old. According to the question, Naron is three times older than his sister, which means his age is 3X.
In two years, Naron's age will be 3X + 2, and his sister's age will be X + 2. The question states that in two years, Naron will be twice as old as his sister.
So, we can write the equation:
3X + 2 = 2(X + 2)
Solving for X, we get:
X = 2
This means that Naron's sister is currently 2 years old. Therefore, Naron's age is 3 times older than his sister, which is 6 years old.
In summary, Naron is currently 6 years old, and his sister is currently 2 years old. Let N represent Naron's age and S represent his sister's age. According to the given information, N = 3S, which means Naron is 3 times older than his sister. In 2 years, Naron's age will be N+2, and his sister's age will be S+2. At that time, Naron will be twice as old as his sister, so N+2 = 2(S+2).
Now, we have two equations:
1) N = 3S
2) N+2 = 2(S+2)
Substitute equation 1 into equation 2:
3S+2 = 2(S+2)
Solve for S:
3S+2 = 2S+4
S = 2

The minimum value of f (x,y,z) = 2x2 + y2 + 3z2 subject to the constraint 2x – 3y - 4z = 49 is 7075/169 using the method of Lagrange multipliers.

To solve this problem, we introduce a Lagrange multiplier λ and form the function

F(x,y,z,λ) = 2x^2 + y^2 + 3z^2 + λ(2x – 3y – 4z – 49)

Taking partial derivatives with respect to x, y, z, and λ, we get

∂F/∂x = 4x + 2λ

∂F/∂y = 2y – 3λ

∂F/∂z = 6z – 4λ

∂F/∂λ = 2x – 3y – 4z – 49

Setting these to zero, we have a system of four equations:

4x + 2λ = 0

2y – 3λ = 0

6z – 4λ = 0

2x – 3y – 4z = 49

Solving for x, y, z, and λ in terms of each other, we get

x = -λ/2

y = 3λ/2

z = 2λ/3

λ = -98/13

Substituting λ back into the expressions for x, y, and z, we get

x = 49/13

y = -147/26

z = -98/39

Finally, substituting these values into the expression for f(x,y,z), we find that the minimum value is f(49/13, -147/26, -98/39) = 7075/169

To evaluate the definite integral ∫(5x^2 - dx)/(x + 2) from 0 to 5, we can use a change of variables.

Let u = x + 2, then du = dx. When x = 0, u = 2, and when x = 5, u = 7. Rewriting the integral in terms of u, we have ∫(5(u - 2)^2 - du)/u. Expanding the squared term, we get ∫(5(u^2 - 4u + 4) - du)/u. Simplifying further, we have ∫(5u^2 - 20u + 20 - du)/u. Now we can split the integral into three parts: ∫(5u^2/u - 20u/u + 20/u - du/u). The integral of 5u^2/u is 5u^2/u = 5u, the integral of 20u/u is 20u/u = 20, and the integral of 20/u is 20 ln|u|. Thus, the integral evaluates to 5u - 20 + 20 ln|u|. Substituting back u = x + 2, the final result is 5(x + 2) - 20 + 20 ln|x + 2|.

Using the dot product, we can find the angle between two vectors if we know their magnitudes and the dot product itself.

The formula to find the angle θ between two vectors A and B is:

θ = cos^(-1)((A · B) / (||A|| ||B||))

where A · B represents the dot product of vectors A and B, ||A|| represents the magnitude of vector A, and ||B|| represents the magnitude of vector B.

To find the angle between two vectors using the dot product, you need to calculate the dot product of the vectors and then use the formula above to find the angle.

Note: The dot product can also be used to determine if two vectors are orthogonal (perpendicular) to each other. If the dot product of two vectors is zero, then the vectors are orthogonal.

If you have specific values for the vectors A and B, you can substitute them into the formula to find the angle between them.

The given initial value problem is y' = (1 – 7x)y, y(0) = 6.Find the solution of the given initial value problem in explicit form:By separation of variables, we can write:y' / y = (1 – 7x)dx. Integrating both sides with respect to x, we have ln |y| = x – (7/2)x^2 + C, where C is a constant of integration. Exponentiating both sides, we get:|y| = e^(x – (7/2)x^2 + C).

Let's consider the constant of integration as C1= e^C and write the equation as follows:|y| = e^x * e^(-7/2)x^2 * C1, where C1 is a positive constant as it is equal to e^C.

Taking the logarithm on both sides, we have ln y = x – (7/2)x^2 + ln C1, for y > 0andln(-y) = x – (7/2)x^2 + ln C1, for y < 0.

Now, we need to use the given initial value y(0) = 6 to find the value of C1 as follows:6 = e^0 * e^0 * C1 => C1 = 6.

Therefore, the solution of the given initial value problem in explicit form is y = e^x * e^(-7/2)x^2 * 6  (for y > 0)and y = - e^x * e^(-7/2)x^2 * 6  (for y < 0).

The general solution of y' -24 can be written in the form y = C is: By integrating both sides with respect to x, we get y = 24x + C, where C is a constant of integration.

The condition of the Alternating Series Test that is not satisfied is A. The terms of the series are not nonincreasing in magnitude.

To show that the given series diverges and determine which condition of the Alternating Series Test is not satisfied, let's analyze the series and its terms.

The series is represented by Σ((-1)^(k+1) / (2k + 1)), where k ranges from 1 to 9. The terms of the series can be denoted as ak = |((-1)^(k+1) / (2k + 1))|.

To identify the behavior of ak, we observe that as k increases, the denominator (2k + 1) becomes larger, while the numerator (-1)^(k+1) alternates between -1 and 1. Therefore, ak is a decreasing function for all k. This eliminates options A and C.

To determine which condition of the Alternating Series Test is not satisfied, we evaluate the limit as k approaches infinity: lim(k→∞) ak. As k increases without bound, the magnitude of the terms ak approaches 0 (since ak is decreasing), satisfying the condition lim(k→∞) ak = 0.

Hence, the condition that is not satisfied is A. . Since ak is a decreasing function, the terms are indeed nonincreasing. Therefore, the main answer is that the condition not satisfied is A.

The expression that describes the field of values (outputs) of the graph of f(x) = -2sin(x) is [-2, 2], and the amplitude of the graph is 2.

In the given function f(x) = -2sin(x), the coefficient of sin(x) is -2. The coefficient, also known as the amplitude, determines the vertical stretching or compressing of the graph. The absolute value of the amplitude represents the maximum displacement from the midline of the graph.

Since the amplitude is -2, we take its absolute value to obtain 2. This means that the graph of f(x) = -2sin(x) has a maximum displacement of 2 units above and below the midline.

Therefore, the field of values (outputs) of the graph is [-2, 2], representing the range of y-values that the graph of f(x) = -2sin(x) can attain.
