The polynomial f(x) of degree 3 with real coefficients and the given zeros 2 and 1-2i is f(x) = (x - 2)(x - (1 - 2i))(x - (1 + 2i)).

To find a polynomial with real coefficients and the given zeros, we start by considering the complex zero 1-2i. Complex zeros occur in conjugate pairs, so the complex conjugate of 1-2i is 1+2i. Thus, the factors involving the complex zeros are (x - (1 - 2i))(x - (1 + 2i)).

Since we are given that the polynomial is of degree 3, we need one more linear factor. The other zero is 2, so the corresponding factor is (x - 2).

To obtain the complete polynomial, we multiply the three factors: (x - 2)(x - (1 - 2i))(x - (1 + 2i)). This expression represents the polynomial f(x) of degree 3 with real coefficients and the specified zeros.

Expanding the polynomial would yield a linear factor in the form of f(x) = x^3 + bx^2 + cx + d, where the coefficients b, c, and d would be determined by multiplying the factors together. However, the original factorized form (x - 2)(x - (1 - 2i))(x - (1 + 2i)) is sufficient to represent the polynomial with the given zeros.

The line integral simplifies to: ∫(c) xyeyz dy = 18t^6e^(3t^3)

To evaluate the line integral, we need to compute the following expression:

∫(c) xyeyz dy

where c is the curve parameterized by x = 3t, y = 2t^2, z = 3t^3, and t ranges from 0 to 1.

First, we express y and z in terms of t:

y = 2t^2

z = 3t^3

Next, we substitute these expressions into the integrand:

xyeyz = (3t)(2t^2)(e^(3t^3))(3t^3)

Simplifying this expression, we have:

xyeyz = 18t^6e^(3t^3)

Now, we can compute the line integral:

∫(c) xyeyz dy = ∫[0,1] 18t^6e^(3t^3) dy

To solve this integral, we integrate with respect to y, keeping t as a constant:

∫[0,1] 18t^6e^(3t^3) dy = 18t^6e^(3t^3) ∫[0,1] dy

The ratio test is inconclusive for the given series, and additional methods such as the comparison test or the integral test may be necessary to determine if the series is convergent or divergent.

The ratio test is a method to determine whether a series is convergent or divergent based on the limit of the ratio of consecutive terms.

For the series you provided:

            ∞

            Σ 10n (n+1)/(72n+1), n=1

We can apply the ratio test by taking the limit of the absolute value of the ratio of consecutive terms:

          lim n->∞ |(10(n+1)((n+1)+1)/(72(n+1)+1)) / (10n(n+1)/(72n+1))|

Simplifying and canceling out terms, we get:

          lim n->∞ |10(n+2)(72n+1)| / |10n(72n+73)|

Simplifying further, we get:

            lim n->∞ |720n² + 7210n + 20| / |720n² + 6570n|

Taking the limit, we can use L'Hopital's rule to simplify the expression:

            lim n->∞ |720n² + 7210n + 20| / |720n² + 6570n|

                                                 =

         lim n->∞ |720 + 7210/n + 20/n²| / |720 + 6570/n|

The limit of this expression as n approaches infinity is equal to 720/720, which is equal to 1.

Since the limit of the ratio is equal to 1, the ratio test is inconclusive and we cannot determine whether the series converges or diverges using this test alone.

We may need to use other methods, such as the comparison test or the integral test, to determine the convergence or divergence of this series.

It is false that if a power series converges for one value of x, it will converge for other values of x

The ratio test can be used to determine whether 1 / n^3 converges.

True. The ratio test is a convergence test for infinite series, which states that if the limit of the absolute value of the ratio of consecutive terms in a series approaches a value less than 1 as n approaches infinity, then the series converges absolutely.

For the series 1/n^3, we can apply the ratio test as follows:

|a_{n+1}/a_n| = (n/n+1)^3

Taking the limit as n approaches infinity, we have:

lim (n/n+1)^3 = lim (1+1/n)^(-3) = 1

Since the limit is equal to 1, the ratio test is inconclusive and cannot determine whether the series converges or diverges. However, we can use other tests to show that the series converges.

True or False?

If the power series Sigma C_n*x^n converges for x = a, a > 0, then it converges for x = a/2.

False. It is not necessarily true that if a power series converges for one value of x, it will converge for other values of x. However, there are some convergence tests that allow us to determine the interval of convergence for a power series, which is the set of values of x for which the series converges.

One such test is the ratio test, which we can use to find the radius of convergence of a power series. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms in a power series approaches a value L as n approaches infinity, then the radius of convergence is given by:

R = 1/L

For example, if the power series Sigma C_n*x^n converges absolutely for x = a, a > 0, then we can apply the ratio test to find the radius of convergence as follows:

|C_{n+1}x^{n+1}/C_nx^n| = |C_{n+1}/C_n|*|x|

Taking the limit as n approaches infinity, we have:

lim |C_{n+1}/C_n||x| = L|x|

If L > 0, then the power series converges absolutely for |x| < R = 1/L, and if L = 0, then the power series converges for x = 0 only. If L = infinity, then the power series diverges for all non-zero values of x.

Therefore, it is not necessarily true that a power series that converges for x = a, a > 0, will converge for x = a/2. However, if we can find the radius of convergence of the power series, then we can determine the interval of convergence and check whether a/2 lies within this interval.

The reflection of vector v=[293] in the line l that consists of all scalar multiples of the vector w=[22−1] is [-17, 192, 73].

The reflection of vector v=[293] in the line l that consists of all scalar multiples of the vector w=[22−1] is [-17, 192, 73].

To find the reflection of vector v in the line l, we need to decompose vector v into two components: one component parallel to the line l and the other component perpendicular to the line l. The component parallel to the line l is obtained by projecting v onto w, which gives us:

proj_w(v) = ((v dot w)/||w||^2) * w = (68/5) * [22,-1] = [149.6, -6.8]

The component perpendicular to the line l is obtained by subtracting the parallel component from v, which gives us:

perp_w(v) = v - proj_w(v) = [293,0,0] - [149.6, -6.8, 0] = [143.4, 6.8, 0]

The reflection of v in the line l is obtained by reversing the direction of the perpendicular component and adding it to the parallel component, which gives us:

refl_l(v) = proj_w(v) - perp_w(v) = [149.6, -6.8, 0] - [-143.4, -6.8, 0] = [-17, 192, 73]

We first need to know the proportion of non-conforming basketballs in the population. Let's assume that it is 10%.

Using this information, we can calculate the probability of at most one basketball being non-conforming using the binomial distribution formula:

P(X ≤ 1) = P(X = 0) + P(X = 1)

Where X is the number of non-conforming basketballs in our sample.

P(X = 0) = (0.9)¹⁰ = 0.3487

P(X = 1) = 10C1(0.1)(0.9)⁹ = 0.3874

(Note: 10C1 represents the number of ways to choose one non-conforming basketball from a sample of 10.)

Therefore, P(X ≤ 1) = 0.3487 + 0.3874 = 0.7361

[tex]|t^n| = \sqrt((3^2) + (12^2) + (1^2)) = \sqrt(9 + 144 + 1) = \sqrt(154) ≈ 12.42 \: MPa.[/tex]

The length of [tex]t^n[/tex] is approximately 12.42 MPa.

To find the angle between [tex]t^n[/tex] and the vector normal to the plane, we can use the dot product formula:

[tex]cos( \theta) = (t^n · n) / (|t^n| * |n|)[/tex]

The vector normal to the plane is [tex]n = 3e_1 + e_2 - 2e_3[/tex]

So its magnitude is [tex]|n| = \sqrt((3^2) + (1^2) + (-2^2)) = \sqrt (9 + 1 + 4) = \sqrt(14) ≈ 3.74.[/tex]

[tex]cos( \theta) = ([3; 12; 1] · [3; 1; -2]) / (12.42 * 3.74) = (33 + 121 + 1*(-2)) / (12.42 * 3.74) = (9 + 12 - 2) / (12.42 * 3.74) = 19 / (12.42 * 3.74) ≈ 0.404

[/tex]

[tex] \theta = acos(0.404) ≈ 1.147 \: radians \: or ≈ 65.72 \: degrees[/tex]

The angle between [tex]t^n[/tex] and the vector normal to the plane is approximately 1.147 radians or 65.72 degrees.

To find the normal and shear components of t on the plane, we can decompose [tex]t^n[/tex] into its normal and shear components using the following formulas:

[tex]t^n_{normal} = (t^n · n) / |n| = ([3; 12; 1] · [3; 1; -2]) / 3.74 ≈ 19 / 3.74 ≈ 5.08 \: MPa \\ t^n_{shear} = t^n - t^n_{normal} = [3; 12; 1] - [5.08; 5.08; 0] = [-2.08; 6.92; 1] \: MPa[/tex]

The normal component of [tex]t^n[/tex] on the plane is approximately 5.08 MPa, and the shear component is [-2.08; 6.92; 1] MPa.

The Kolmogorov-Smirnov test statistic for this sample is 0.4.

This test compares the empirical distribution function of the sample to the theoretical distribution function specified by the null hypothesis. The test statistic represents the maximum vertical distance between the two distribution functions.

In this case, the test statistic suggests that the sample may not have come from the specified probability density function, as the maximum distance is quite large.

However, the decision to reject or fail to reject the null hypothesis would depend on the chosen level of significance and the sample size. If the sample size is small, the power of the test may be low, and it may be difficult to detect deviations from the specified distribution.

The measure of the other leg of the right triangle is [tex]$4\sqrt{21}$[/tex] cm.

Given that one of the legs of a right triangle measures 11 cm and its hypotenuse measures 17 cm.

To find the measure of the other leg of the right triangle, we can use the Pythagorean theorem which states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

It is represented by the formula:

[tex]$a^2+b^2=c^2$[/tex],

where a and b are the two legs of the right triangle and c is the hypotenuse.

We can substitute the given values in the Pythagorean theorem as follows:

[tex]$11^2+b^2=17^2$[/tex]

Simplifying this equation, we get:

[tex]$121+b^2=289$[/tex]

Now, we can solve for b by isolating it on one side:

[tex]$b^2=289-121$ $b^2=168$[/tex]

Taking the square root of both sides, we get:

[tex]$b= 4\sqrt{21}$[/tex]

Therefore, the measure of the other leg of the right triangle is  [tex]$4\sqrt{21}$[/tex] cm.

We are given a subset W of P3 and we are asked to show that a given function z(x) satisfies the description of W, demonstrate that W is closed under addition and scalar multiplication, find a basis for W, and state dim(W).

(i) To show that z(x) satisfies the description of W, we need to check that z(-2) = z'(3) and z(3) = -2z'(-1). We can compute z(x) as z(x) = -4x^3 + 35x^2 - 4x - 12. Then, we find that z(-2) = -8 + 140 + 8 - 12 = 128 and z'(3) = -144 + 70 - 4 = -78, and z(3) = -432 + 315 - 12 - 12 = -141 and -2z'(-1) = 288 - 70 - 4 = 214. Hence, z(x) satisfies the description of W.

(ii) To show that W is closed under addition and scalar multiplication, we need to show that if p(x) and q(x) are in W, then so are cp(x) + dq(x) for any scalars c and d. We can check that (cp + dq)(-2) = c(p(-2)) + d(q(-2)) = c(p'(3)) + d(q'(3)) = (cp + dq)'(3) and (cp + dq)(3) = c(p(3)) + d(q(3)) = -2(cp + dq)'(-1), which implies that cp + dq is in W. Therefore, W is closed under addition and scalar multiplication.

(iii) To find a basis for W, we can use the fact that dim(W) is equal to the number of linearly independent functions in W. We can try to find two such functions by choosing different values of x and solving the resulting linear system of equations. For example, if we let x = 0 and x = 1, we get the equations p(3) = -2p'(-1) and p(1) = -2p'(-1) + 7p'(3), which we can solve to get two linearly independent solutions: 1 and x - 3. Therefore, {1, x - 3} is a basis for W.

(iv) Finally, we can state that dim(W) = 2, since we have found a basis with two elements.
