What is the shape of the cross - section

To calculate the equal monthly payments for a 6-year, $50,000 loan at a nominal annual interest rate of 10% compounded monthly, we can use the formula for the monthly payment on a loan:

P = (r(PV))/(1 - (1 + r)^(-n))

where P is the monthly payment, r is the monthly interest rate (which is the nominal annual rate divided by 12), PV is the present value of the loan (which is $50,000), and n is the total number of monthly payments (which is 6 years times 12 months per year, or 72).

First, we need to calculate the monthly interest rate:

r = 0.10/12 = 0.0083333

Next, we can substitute these values into the formula to calculate the monthly payment:

P = (0.0083333(50000))/(1 - (1 + 0.0083333)^(-72)) = $843.86

Therefore, the equal monthly payments for this loan would be $843.86, starting at the end of the first month.

(a) The sketch of the plane curve with the given vector equation is illustrated below.

(b) The resulting picture is a curve in the xy-plane with the position vector r(37/4) and the tangent vector r'(37/4) at that point.

(c) The sketch of the position vector r(t) and the tangent vector r'(t) for the given value of t is illustrated below.

To find r'(t), we need to take the derivative of r(t) with respect to t. Since the coefficients of i and j are functions of t, we need to use the chain rule. The result is r'(t) = 4 cos(t)i + 2 sin(t)j. This vector represents the tangent vector to the curve at the point r(t) for any given value of t.

Now, let's sketch the curve together with the position vector r(t) and the tangent vector r'(t) for t = 37/4.

To do this, we can plot the point (4sin(37/4), -2cos(37/4)) on the xy-plane and draw a vector from the origin to this point, which represents r(37/4). We can also draw a tangent vector to the curve at this point, which represents r'(37/4).

Since

=> r'(37/4) = 4cos(37/4)i + 2sin(37/4)j,

we can plot this vector starting at the point r(37/4) and extending in the direction of the vector.

The answer is , The braking distance of the Cadillac Escalade that corresponds to z=1.2 is approximately 166.14 feet. The option is (a) .

Given that the mean stopping distance is 157.5 feet and the standard deviation is 7.2 feet.

We need to find the braking distance of the Cadillac Escalade that corresponds to z=1.2.

Because the distribution is normal, we can use the z-score formula to find the corresponding braking distance:

z=(x-μ)/σ

where z=1.2, μ=157.5, and σ=7.2

We can solve for x by rearranging the equation:

x = zσ + μx

= 1.2(7.2) + 157.5x

= 8.64 + 157.5x

= 166.14

The braking distance of the Cadillac Escalade that corresponds to z=1.2 is approximately 166.14 feet.

Therefore, the correct option is (a) 166.14 feet.

The required answer is every 5 times we roll the dice and don't get a sum of 7, we can expect to get a sum of 7 once.

To find the probability of odds against a sum of 7 when rolling a pair of dice one time, we need to first determine the number of ways to get a sum of 7 versus the number of ways to get any other sum.
There are a total of 36 possible outcomes when rolling a pair of dice, as there are six possible outcomes for each die (1, 2, 3, 4, 5, or 6). To get a sum of 7, there are 6 possible combinations: 1+6, 2+5, 3+4, 4+3, 5+2, and 6+1. Therefore, the probability of rolling a sum of 7 is 6/36 or 1/6.

To find the odds against rolling a sum of 7, we can use the formula:
Odds against = (number of ways it won't happen) : (number of ways it will happen)
So the number of ways it won't happen (i.e. rolling any sum other than 7) is 36-6, or 30. Therefore, the odds against rolling a sum of 7 are:
Odds against = 30 : 6
Simplifying, we get:
Odds against = 5 : 1
This means that for every 5 times we roll the dice and don't get a sum of 7, we can expect to get a sum of 7 once.

The fundamental matrix Φ(t) satisfying Φ(0) = I for the given first-order system x' = [[-1, 1], [-4, -1]]x is Φ(t) = [[e^(-t), te^(-t)], [-4te^(-t), e^(-t)]].

The fundamental matrix is a matrix whose columns are the linearly independent solutions of the given system of differential equations. In this case, we are given the matrix representation of the system and we need to find the fundamental matrix Φ(t).

To find Φ(t), we first need to find the eigenvalues and eigenvectors of the coefficient matrix A = [[-1, 1], [-4, -1]]. The eigenvalues can be found by solving the characteristic equation det(A - λI) = 0, where λ is the eigenvalue and I is the identity matrix.

Solving det(A - λI) = 0, we find that the eigenvalues are λ₁ = -2 and λ₂ = -3.

Next, we find the corresponding eigenvectors. For λ₁ = -2, we solve the equation (A - λ₁I)v₁ = 0, where v₁ is the eigenvector. Similarly, for λ₂ = -3, we solve (A - λ₂I)v₂ = 0, where v₂ is the eigenvector.

After finding the eigenvectors, we construct the fundamental matrix Φ(t) using the formula Φ(t) = [v₁ e^(λ₁t), v₂ e^(λ₂t)], where e^(λ₁t) and e^(λ₂t) are the exponential terms corresponding to the eigenvalues.

Finally, we substitute the eigenvalues and eigenvectors into the formula and simplify to obtain the fundamental matrix Φ(t) = [[e^(-t), te^(-t)], [-4te^(-t), e^(-t)]], which satisfies Φ(0) = I.

This result shows that the eigenvalues of A^2 are the squares of the eigenvalues of A, and the eigenvectors of A and A^2 are the same

Let λ be the eigenvalue associated with eigenvector v of matrix A. Then by definition, we have:

Av = λv

Now consider the matrix A^2. We can write A^2 as the product A * A, so we have:

A^2 v = A(Av) = A(λv) = λ(Av)

Note that Av = λv, so we have:

A^2 v = λ(Av) = λ(λv) = λ^2 v

This shows that v is an eigenvector of A^2 with associated eigenvalue λ^2. To see why, note that we have shown that A^2 v is a scalar multiple of v, with the scalar being λ^2. This means that v is an eigenvector of A^2 with associated eigenvalue λ^2.

Therefore, we have shown that if v is an eigenvector of A with associated eigenvalue λ, then v is an eigenvector of A^2 with associated eigenvalue λ^2.

To summarize:

If Av = λv, then A^2 v = λ^2 v.

So, v is an eigenvector of A^2 with associated eigenvalue λ^2.

a) the vertices are (9, 0) and (-3, 0).

the foci are (3 ± 2√10, 0)

the asymptotes are y = ±x/3 - 1

b) the equation of the ellipse is x² + (y-√5/2)² = 5/4

a)  To find the foci, vertices, and asymptotes of the ellipse (x - 3)² - 9y² = 36, we can first divide both sides by 36 to get:

[tex]\frac{(x-3)^2}{36} - \frac{y^2}{4}=1[/tex]

Therefore, the center of the ellipse is (3, 0).

The semi-major axis length is √36 = 6, and the semi-minor axis length is √4 = 2.

Therefore, the vertices are (3 ± 6, 0) = (9, 0) and (-3, 0).

The foci are located at a distance of √(6²-2²) = 2√10 from the center along the major axis. Therefore, the foci are (3 ± 2√10, 0) and the equation of the major axis is x = 3.

To find the asymptotes, we will use the formula:

[tex]\frac{y-k}{b} = \pm\frac{x-h}{a}[/tex]

where (h, k) is the center of the ellipse, a is the length of the semi-major axis, and b is the length of the semi-minor axis. Therefore, the equations of the asymptotes are:

(y-0)/2 = ±(x-3)/6

y = ±x/3 - 1

b) To find the equation of the ellipse with foci (0, 2) and semi-major axis length 3, we can first find the center of the ellipse. Since the foci are located on the y-axis, the center must also be located on the y-axis. Therefore, the center is (0, c), where c is the distance between the center and one of the foci.

Since the semi-major axis length is 3, the distance between the center and one of the vertices is 3. Therefore, we have:

c² + (3/2)² = (3/2+2)²

c² = 5/4

Therefore, the center of the ellipse is (0, √5/2). The distance between the center and one of the foci is √5/2 - 2. Therefore, the distance between the center and one of the vertices is √{(√5/2)² - (√5/2 - 2)²} = √5.

Therefore, the semi-minor axis length is √5/2, and the equation of the ellipse is:

[tex]\frac{x^2}{\frac{5}{4} } +\frac{(y-\frac{\sqrt{5}}{2} )^2}{\frac{5}{4} } =1[/tex]

To find the Taylor polynomials t2(x) and t3(x) for f(x) = ln(x+1) centered at x=4, we need to evaluate the function and its derivatives at x=4.

f(4) = ln(5)

f'(x) = 1/(x+1), so f'(4) = 1/5

f''(x) = -1/(x+1)^2, so f''(4) = -1/25

f'''(x) = 2/(x+1)^3, so f'''(4) = 2/125

Using these values, we can plug them into the general formula and simplify to get:

The solution of the given initial value problem is y(r) = (1/9) cos(3r) + (1/9) sin(3r) - (1/9) sin(3r) = (1/9) cos(3r)

We are given the initial value problem:

d^2y/dr^2 + 9y = sin(3r), y(0) = y'(0) = 0 ---------(1)

We can write the characteristic equation for the given differential equation as:

r^2 + 9 = 0

The roots of the characteristic equation are: r = 0 ± 3i

So, the general solution of the homogeneous differential equation d^2y/dr^2 + 9y = 0 is:

y_h(r) = c1 cos(3r) + c2 sin(3r) ------------(2)

Now, we will find the particular solution of the given differential equation. We use the method of undetermined coefficients and assume the particular solution to be of the form:

y_p(r) = A sin(3r) + B cos(3r)

Differentiating y_p(r) w.r.t r, we get:

y_p'(r) = 3A cos(3r) - 3B sin(3r)

Differentiating y_p'(r) w.r.t r, we get:

y_p''(r) = -9A sin(3r) - 9B cos(3r)

Substituting these values in the differential equation (1), we get:

-9A sin(3r) - 9B cos(3r) + 9(A sin(3r) + B cos(3r)) = sin(3r)

Simplifying the above equation, we get:

-9A sin(3r) + 9B cos(3r) = sin(3r)

Comparing the coefficients of sin(3r) and cos(3r) on both sides, we get:

-9A = 1 and 9B = 0

Solving the above equations, we get:

A = -(1/9) and B = 0

So, the particular solution of the given differential equation is:

y_p(r) = -(1/9) sin(3r)

Therefore, the general solution of the given differential equation is:

y(r) = y_h(r) + y_p(r) = c1 cos(3r) + c2 sin(3r) - (1/9) sin(3r) ------------(3)

Now, we will apply the initial conditions to find the values of c1 and c2.

Given that y(0) = 0. Substituting r = 0 in equation (3), we get:

c1 - (1/9) = 0

So, c1 = 1/9

Differentiating equation (3) w.r.t r, we get:

y'(r) = -3c1 sin(3r) + 3c2 cos(3r) - (1/3) cos(3r)

Given that y'(0) = 0. Substituting r = 0 in the above equation, we get:

3c2 = (1/3)

So, c2 = (1/9)

Therefore, the solution of the given initial value problem is:

y(r) = (1/9) cos(3r) + (1/9) sin(3r) - (1/9) sin(3r) = (1/9) cos(3r)

Substituting r sin(θ) = 4 into the second equation gives y = 4/r cos(θ). We can now substitute r^2 = x^2 + y^2 into this equation to get:

y = 4/√(x^2 + y^2) * x/√(x^2 + y^2)

Simplifying this equation gives:

x^2 + y^2 = (4/y)^2

This is the equation of a circle centered at the origin with radius r = 16/y. However, we need to be careful because the original polar equation is only defined for θ values where sin(θ) ≠ 0, or in other words, θ ≠ kπ for any integer k.

When we look at the Cartesian equation x^2 + y^2 = (4/y)^2, we can see that it is undefined at y = 0. However, we know that the original polar equation is defined for all values of θ except θ = kπ. Therefore, we can say that the resulting curve is a circle centered at the origin with radius r = 16/y for all values of y except y = 0.

In summary, the Cartesian equation is x^2 + y^2 = (4/y)^2, and the resulting curve is a circle centered at the origin with radius r = 16/y for all values of y except y = 0.

The series converges for values of x such that |x-4| < 1, since the series for ln(1+x) converges for |x| < 1.

To find the Maclaurin series for f(x) = ln(x-4), we can use the formula for the Maclaurin series of ln(1+x), which is:

ln(1+x) = ∑ n=1[infinity] ((-1)^ⁿ⁺ / n) * xⁿ

We can apply this formula by replacing x with (x-4), which gives us:
ln(x-3) = ln(1 + (x-4)) = ∑ n=1[infinity] ((-1)^(n+1) / n) * (x-4)ⁿ

Therefore, the Maclaurin series for f(x) = ln(x-4) is:
f(x) = ∑ n=1[infinity] ((-1)^ⁿ⁺¹ / n) * (x-4)ⁿ

This series converges for values of x such that |x-4| < 1, since the series for ln(1+x) converges for |x| < 1.

Computing the vector assigned to the points P=(0,6,-3) and Q=(9,1,0) by the vector field F(P)=F(Q) is that we can estimate the vectors based on assumptions about the smoothness and continuity of the vector field, and nearby points.

To compute the vector assigned to the points p=(0,6,-3) and q=(9,1,0) by the vector field f=F(P)=F(Q), we need to evaluate the vector field at each point.

The vector field F(P) tells us the direction and magnitude of the vector at point P.

In this case, we don't have a specific formula for the vector field, so we can't simply plug in the coordinates of P and Q to get the vectors.

However, we can make an educated guess based on the given points.

Looking at the coordinates of P and Q, we can see that they are not aligned along any of the coordinate axes.

This suggests that the vector field may be twisting or curving in some way.

Without more information, we can't say for sure what the vector field looks like, but we can make some assumptions and use our intuition.

One possible assumption is that the vector field is smooth and continuous, meaning that the vectors at nearby points are similar in direction and magnitude.

If we assume this, we can estimate the vectors at P and Q by looking at the nearby points.

For example, we can look at the points (1,6,-3) and (0,5,-3) that are close to P. The vector from P to (1,6,-3) is (1,0,0), and the vector from P to (0,5,-3) is (0,-1,0).

These vectors suggest that the vector field is pointing slightly to the right and slightly down at P.

Similarly, we can look at the points (9,2,0) and (9,1,-1) that are close to Q. The vector from Q to (9,2,0) is (0,1,0), and the vector from Q to (9,1,-1) is (0,0,1).

These vectors suggest that the vector field is pointing slightly up and slightly forward at Q.

Based on these assumptions and estimates, we can assign approximate vectors to P and Q:

- The vector at P is approximately (-0.5,-0.5,0.5), pointing slightly to the right, slightly down, and slightly forward.
- The vector at Q is approximately (0,0.5,0.5), pointing slightly up and slightly forward.


In summary, the long answer to the question of computing the vector assigned to the points P=(0,6,-3) and Q=(9,1,0) by the vector field F(P)=F(Q) is that we can estimate the vectors based on assumptions about the smoothness and continuity of the vector field, and nearby points.

The measure of the angles are;

m<AED = 90 degrees

m<DAE = 43 degrees

m<BCE = 37 degrees

To determine the measure of the angles, we need to know the following;

From the information given, we have that;

m<AED is right- angled thus is equal to 90 degrees

But we have that;

m<DAE + m<EDA + m<AED = 180

Then,

m<DAE + 37 + 90 = 180

collect the like terms

m<DAE = 180 - 137

m<DAE = 43 degrees

m<BCE = m<EDA

Hence, m<BCE = 37 degrees

The measure of the arc is:

x = 120°

The arc of a circle is the part or segment of the circumference of a circle. A straight line drawn by connecting the two ends of the arc is called chord of a circle.

Check the attached image for labeling.

y = 180° (semicircle)

The measure of inscribed angle is half the measure of its intercepted arc. That is:

30° = 1/2 * U

U = 2 * 30

U = 60°

x = 360 - U - y  (sum of angles in a circle is 360°)

x = 360 - 60 - 180

x = 120°

The height of the tree, found using the distances in the diagram and Pythagorean Theorem is about 92.49 feet

The Pythagorean Theorem express the relationship between the lengths of the sides of a right triangle. The theorem states that the square of the hypotenuse side of a right triangle is equivalent to the sum of the squares of the other two sides of the triangle.

The distances in the drawing, whereby the tree is vertical indicates;

The distance line from the person to the top of the tree, the height of the person, and the distance from the base of the tree to the person forms a right triangle

Hypotenuse side = The distance line from the person to the top of the tree, h

The legs = The height of the tree, y and the distance from the person to the base of the tree, x

Pythagorean theorem indicates that we get;

h² = y² + x²

h = 102, x = 43, therefore;

102² = y² + 43²

y² = 102² - 43² = 8555

The height of the tree, y = √(8555) ≈ 92.49
