ANSWERS

1. Domain: all real values

2. Zeros: 0 (with multiplicity 2) and 3

3. Not periodic. Symmetric about the point (1, 2)

4. Positive for x < 3; negative for x > 3

5. f → ∞ as x → -∞; f → -∞ as x → ∞

6. none

EXPLANATION

1. The domain of a function is the set of all the x-values for which the function exists. In this case, we have a polynomial function and, therefore, the domain is all real values.

2. To find the zeros of the function, we have to solve,

First, factor x² and -1 out. To do so, we have to divide each term by x² and by -1 - or, in other words, divide by -x²,

So, we have,

In this equation, we can see that if x = 0, then the equation is true. Also, if x = 3 the equation is true. So, these are the two zeros, with the particularity that x = 0 has multiplicity 2. This is because the factor related to that zero is x squared.

Hence, the zeros are 0 and 3. 0 has multiplicity 2.

3. As mentioned before, this is a polynomial function, which means that it is not a periodic function. A cubic function is an odd function, and it is symmetric about the origin. However, this function is not the parent function, x³, but it is symmetric about the point (1, 2).

4. We know that the function is zero at x = 0 and at x = 3. For x < 0, the function is positive,

For 0 < x < 3, the function is also positive. This is because x = 0 with multiplicity 2.

Then, since the function crosses the x-axis at x = 3 and that zero has multiplicity 1, we can conclude that the function is negative for x > 3.

Hence, is the function is positive for x < 3 and negative for x > 3.

5. As mentioned in part 4, the function is positive for all values of x less than 3, which means that the function goes to infinity as x goes to negative infinity.

Since for x > 3 the function is always negative, it goes to negative infinity as x goes to infinity.

6. A polynomial function has no restrictions in the domain and, therefore, has no asymptotes.

Answer:

f (3) = 21

Step-by-step explanation:

To answer, we know that x in f (x) equals 3, so in f (x) = 7x, we simply substitute x with 3:

f (3) = 7 (3)

Now multiply:

f (3) = 21

In summary the equivalence relation on the set of real numbers is:

- [1] = {x ∈ R | x = 1 + q, q ∈ Q}

- [1/2] = {x ∈ R | x = 1/2 + q, q ∈ Q}

- [π] = {x ∈ R | x = π + q, q ∈ Q}

The union of both rational and irrational numbers is known as a real number. They are represented by the letter "R" and can be either positive or negative.

To show that the relation {(x, y) | x − y ∈ Q} is an equivalence relation on the set of real numbers, we need to verify three properties: reflexivity, symmetry, and transitivity.

1. Reflexivity: For any real number x, we have x - x = 0, which is a rational number (0 ∈ Q). Therefore, (x, x) ∈ {(x, y) | x − y ∈ Q} for all x, and the relation is reflexive.

2. Symmetry: If (x, y) ∈ {(x, y) | x − y ∈ Q}, then x - y is a rational number. Since the negation of a rational number is still a rational number, -(x - y) = y - x is also a rational number. Therefore, (y, x) ∈ {(x, y) | x − y ∈ Q}, and the relation is symmetric.

3. Transitivity: If (x, y) ∈ {(x, y) | x − y ∈ Q} and (y, z) ∈ {(x, y) | x − y ∈ Q}, then x - y and y - z are both rational numbers. The sum of two rational numbers is also a rational number, so (x - y) + (y - z) = x - z is a rational number. Therefore, (x, z) ∈ {(x, y) | x − y ∈ Q}, and the relation is transitive.

Since the relation satisfies all three properties (reflexivity, symmetry, and transitivity), it is an equivalence relation on the set of real numbers.

Now, let's determine the equivalence classes [1], [1/2], and [π].

The equivalence class [1] consists of all real numbers x such that x - 1 ∈ Q. In other words, [1] = {x ∈ R | x - 1 ∈ Q}. This means that any real number x in the form x = 1 + q, where q is a rational number, belongs to [1].

Similarly, the equivalence class [1/2] consists of all real numbers x such that x - 1/2 ∈ Q. Therefore, [1/2] = {x ∈ R | x - 1/2 ∈ Q}, which means that any real number x in the form x = 1/2 + q, where q is a rational number, belongs to [1/2].

Finally, the equivalence class [π] consists of all real numbers x such that x - π ∈ Q. Thus, [π] = {x ∈ R | x - π ∈ Q}. This means that any real number x in the form x = π + q, where q is a rational number, belongs to [π].

In summary:

- [1] = {x ∈ R | x = 1 + q, q ∈ Q}

- [1/2] = {x ∈ R | x = 1/2 + q, q ∈ Q}

- [π] = {x ∈ R | x = π + q, q ∈ Q}

The solution to the given differential equation with the initial condition y = 70 when x = 0 is y - 10xy² - 10xC₁  = x + 70

To solve the given differential equation:

dy - 10xy = dx

We can rearrange it as:

dy = 10xy dx + dx

Now, let's separate the variables by moving all terms involving y to the left side and all terms involving x to the right side:

dy - 10xy dx = dx

To integrate both sides, we will treat y as the variable to integrate with respect to and x as a constant:

∫dy - 10x∫y dx = ∫dx

Integrating both sides, we get:

y - 10x * ∫y dx = x + C

Now, let's evaluate the integral of y with respect to x:

∫y dx = xy + C₁

Substituting this back into the equation:

y - 10x(xy + C₁) = x + C

y - 10xy² - 10xC₁ = x + C

Next, let's apply the initial condition y = 70 when x = 0:

70 - 10(0)(70²) - 10(0)C₁ = 0 + C

Simplifying:

70 - 0 - 0 = C

C = 70

Substituting this value of C back into the equation:

y - 10xy² - 10xC₁ = x + 70

Thus, the solution to the given differential equation with the initial condition y = 70 when x = 0 is y - 10xy² - 10xC₁ = x + 70

Answer:

It c

Step-by-step explanation:

She applied the exponent Negative 2 to 4 (negative 2) instead of applying the exponent to just Negative 2.

For the sequence the correct statement is Monotonic, bounded, and divergent. So the correct answer is option (c).

To determine which statement is true for the sequence defined as 12 + 22 + 32 + ... + (n + 2)2, let's examine the pattern of the sequence.

The given sequence represents the sum of squares of consecutive natural numbers starting from 1. In other words, it can be written as:

12 + 22 + 32 + ... + n2 + (n + 1)2 + (n + 2)2

Expanding the squares, we have:

1 + 4 + 9 + ... + n2 + n2 + 2n + 1 + n2 + 4n + 4

Combining like terms, we get:

3n2 + 6n + 6

Now, let's substitute n = 10 into the expression:

3(10)2 + 6(10) + 6

= 300 + 60 + 6

= 366

Therefore, when n = 10, the sum of the sequence is 366.

Now, let's analyze the given statements:

(a) Monotonic, bounded, and convergent.

(b) Not monotonic, bounded, and convergent.

(c) Monotonic, bounded, and divergent.

(d) Monotonic, unbounded, and divergent.

(e) Not monotonic, unbounded, and divergent.

To determine whether the sequence is monotonic, we need to check if the terms of the sequence consistently increase or decrease.

If we observe the given sequence, we can see that the terms are increasing, as we are adding squares of consecutive natural numbers. So, the sequence is indeed monotonic.

Regarding boundedness, as the sequence is increasing, it is not bounded above. Therefore, it is not bounded.

Lastly, since the sequence is not bounded, it cannot be convergent. Instead, it is divergent.

Based on these analyses, the correct statement for the given sequence is:

Monotonic, bounded, and divergent. So option c is the correct answer.

Yes, it is possible to find a limit at a location where there is a hole in a graph , such as where a point has been removed or where a graph abruptly stops.

This is because the limit of a function is defined as the value that the function approaches as x approaches a given value. In the case of a hole in the graph, the limit is found by looking at the limit from the left, the limit from the right, and the general limit.

The limit from the left is the limit of the function as x approaches the hole from the left. The limit from the right is the limit of the function as x approaches the hole from the right. The general limit is the overall limit of the function at the point where the hole appears. By considering all of these limits, it is possible to determine the overall limit of the function at the point where the hole is present.

Solution :

Given initial velocity, v= 48 ft/s

Acceleration due to gravity, g = \($12\ ft/s^2$\)

a). Therefore the maximum height he can jump on Mars is

     \($H_{max}=\frac{v^2}{2g}$\)

     \($H_{max} = \frac{(48)^2}{2 \times 12}$\)

               = 96 ft

b). Time he can stay in the air before hitting the ground is

   \($T=\frac{2v}{g}$\)

  \($T=\frac{2 \times 48}{12}$\)

     = 8 seconds

c).  Considering upward motion as positive direction.

     v = u + at

We find the time taken to reach the maximum height by taking v = 0.

     v = u + at

     0 = 16 + (12) t

     \($t=\frac{16}{12}$\)

        \($=\frac{4}{3} \ s$\)

We know that, \($S=ut + \frac{1}{2}at^2$\)

Taking t =  \($=\frac{4}{3} \ s$\)  , we get

\($S=16 \times\frac{4}{3} + \frac{1}{2}\times(-12) \times \left(\frac{4}{3}\right)^2$\)

\($S=\frac{32}{3}$\)  feet

Thus he can't reach to 100 ft as it is shown in the movie.

d). For any jump whose final landing position will be same of the take off level, the final velocity will be the initial velocity.

Step-by-step explanation:

The equation \(4x^2u^n + (1-x^2)u = 0\) has two solutions. One solution is given by \(u_1 = x^{1/2}\left(1 + \frac{x^2}{16} + \frac{x^4}{1024} + \dots\right)\). The other solution is not provided in the given question.

To find the solutions, we can rewrite the equation as \(u^n = -\frac{1-x^2}{4x^2}u\). Taking the square root of both sides gives us \(u = \pm\left(-\frac{1-x^2}{4x^2}\right)^{1/n}\). Now, let's focus on finding the positive solution.

Expanding the expression inside the square root using the binomial series, we have:

\[\left(-\frac{1-x^2}{4x^2}\right)^{1/n} = -\frac{1}{4^{1/n}x^{2/n}}\left(1 + \frac{(1-x^2)}{4x^2}\right)^{1/n}\]

Since \(|x| < 1\) (as \(x\) is a fraction), we can use the binomial series expansion for \((1+y)^{1/n}\), where \(|y| < 1\):

\[(1+y)^{1/n} = 1 + \frac{1}{n}y + \frac{1-n}{2n^2}y^2 + \dots\]

Substituting \(y = \frac{1-x^2}{4x^2}\), we get:

\[\left(-\frac{1-x^2}{4x^2}\right)^{1/n} = -\frac{1}{4^{1/n}x^{2/n}}\left(1 + \frac{1}{n}\cdot\frac{1-x^2}{4x^2} + \frac{1-n}{2n^2}\cdot\left(\frac{1-x^2}{4x^2}\right)^2 + \dots\right)\]

Simplifying and rearranging terms, we find the positive solution as:

\[u_1 = x^{1/2}\left(1 + \frac{x^2}{16} + \frac{x^4}{1024} + \dots\right)\]

The second solution is not provided in the given question, but it can be obtained by considering the negative sign in front of the square root.
