Draw a line from (2,3) to (21,12) using DDA?

The sequence (xn) = yn + (-1)^n/n, where (yn) is a divergent sequence, also diverges.

To prove that the sequence (xn) diverges, we need to show that it does not have a finite limit.

Assuming that (xn) converges to a finite limit L, we can write:

lim(n→∞) xn = L

Since (yn) is a divergent sequence, it does not converge to any finite limit. Let's consider two subsequences of (yn), namely (yn1) and (yn2), such that (yn1) → ∞ and (yn2) → -∞ as n → ∞.

For the subsequence (yn1), we have:

xn1 = yn1 + (-1)^n/n

As n approaches infinity, the term (-1)^n/n oscillates between positive and negative values, which means that (xn1) does not converge to a finite limit.

Similarly, for the subsequence (yn2), we have:

xn2 = yn2 + (-1)^n/n

Again, as n approaches infinity, the term (-1)^n/n oscillates, leading to the divergence of (xn2).

Since we have found two subsequences of (xn) that do not converge to a finite limit, it follows that the sequence (xn) = yn + (-1)^n/n also diverges.

Therefore, the sequence (xn) diverges.

Step-by-step explanation:

Part A: The expression to represent the amount of canned food collected so far by the three friends is 4x² + 3xy + 8.

Part B: The expression representing the number of cans the friends still need to collect to meet their goal is 5x² - 8xy - 2.

Part A: We shall sum the number of cans collected by each friend to find the amount of canned food collected by the three.

Given:

Jessa collected: 3xy - 7 cans.

Tyree collected: 3x² + 15 cans.

Ben collected: x² cans.

First, we sum the number of cans collected by each:

Total = (3xy - 7) + (3x² + 15) + (x²)

Then we combine the  like terms:

Total = 3xy + 3x² + 15 + x² - 7  

Simplify:

Total = 4x² + 3xy + 8

So, the expression to represent the amount of canned food collected so far by the three friends is 4x² + 3xy + 8.

Part B: We subtract the total amount collected by the three friends from their goal expression, 9x² - 5xy + 6 to find the number of cans the friends still need to collect to meet their goal.

Amount needed = (9x² - 5xy + 6) - (4x² + 3xy + 8)

Amount needed = 9x² - 5xy + 6 - 4x² - 3xy - 8

Join the like terms:

Amount needed = (9x² - 4x²) + (-5xy - 3xy) + (6 - 8)

Simplifying:

Amount  needed = 5x² - 8xy - 2

Hence, 5x² - 8xy - 2 is the expression representing the number of cans the friends still need to collect to meet their goal.

a. The equation of tangent line is  : y = 2x + 1.

b. The equation of the tangent line is y = (3/25)x + 16/75.

a. y = 4x³ + 2x - 1 at (0,-1)

The equation of the tangent to the curve y = f (x) at the point where x = a is given by

y - f (a) = f'(a) (x - a).

Thus, in the first case, we need to find f'(a) and substitute the values of x, y, and a to find the tangent equation.

f(x) = 4x³ + 2x - 1

Taking the derivative of the function,

f'(x) = 12x² + 2

The slope of the tangent line at (0, -1) can be found by substituting x = 0, which yields f'(0) = 2.

Substituting the point (0,-1) and the value of the slope m = f'(0) = 2 in the point-slope form,

we have the equation of the tangent line,

y - (-1) = 2(x - 0)

y + 1 = 2x + 0

b. g(x) = x/(x²+4) at the point where x=1.

The slope of the tangent to g(x) at x = a is given by

f'(a).g(x) = x/(x²+4)

Taking the derivative of the function,

g'(x) = [x² + 4 - x (2x)]/(x² + 4)²

g'(x) = (4 - x²)/(x² + 4)²

The slope of the tangent line at x = 1 can be found by substituting x = 1, which yields

g'(1) = 3/25.

Substituting the point (1, 1/5) and the value of the slope m = g'(1) = 3/25 in the point-slope form, we have the equation of the tangent line,

The function f(x) = x^4e^x has one critical point at x = -4 and two intervals of increase and decrease. It has no local maximum value but has an absolute minimum value of -4e^-4.

To determine the intervals of increase and decrease, we need to find the derivative of the function f(x) with respect to x. Taking the derivative, we get: f'(x) = 4x^3e^x + x^4e^x = x^3e^x(4 + x)

Setting f'(x) equal to zero, we find the critical point: x^3e^x(4 + x) = 0

This equation is satisfied when x = -4 or x = 0. However, x = 0 does not affect the intervals of increase and decrease since it does not change the sign of the derivative. Therefore, the critical point is x = -4.

Next, we examine the intervals around the critical point. For x < -4, f'(x) is negative, indicating a decreasing interval. For x > -4, f'(x) is positive, indicating an increasing interval. Thus, we have one interval of decrease (-∞, -4) and one interval of increase (-4, +∞).

To find the absolute minimum value, we evaluate the function at the critical point and the endpoints of the intervals. Plugging x = -4 into f(x), we get f(-4) = (-4)^4e^(-4) = 256e^-4 ≈ 0.0114. Evaluating the function at the endpoints of the intervals, we find that as x approaches ±∞, f(x) also approaches ±∞. Therefore, the absolute minimum value occurs at x = -4 and is approximately -4e^-4.

In summary, the function f(x) = x^4e^x has one critical point at x = -4 and two intervals of increase and decrease. It has no local maximum value but has an absolute minimum value of -4e^-4.

The derivative of y = x^4 sin(x) with respect to x is dy/dx = 4x^3 sin(x) + x^4 cos(x).

To find the derivative of y = x^4 sin(x), we use the product rule of differentiation. Let's denote f(x) = x^4 and g(x) = sin(x). Applying the product rule, we have:

dy/dx = f'(x)g(x) + f(x)g'(x).

Differentiating f(x) = x^4 with respect to x gives f'(x) = 4x^3, and differentiating g(x) = sin(x) with respect to x gives g'(x) = cos(x). Substituting these values into the product rule formula, we get:

dy/dx = 4x^3 sin(x) + x^4 cos(x).

Therefore, the derivative of y = x^4 sin(x) with respect to x is dy/dx = 4x^3 sin(x) + x^4 cos(x).

We have given a function f(x, y) = In (1 + 4x^2 + 6y^2) and point P (1/2 -√2).

The gradient of the function f(x, y) is obtained by differentiating with respect to both variables x and y separately.f(x, y) =

= 12y / (1 + 4x^2 + 6y^2) . . .(2)

Therefore, the gradient of the function f(x, y) is (f'x(x, y), f'y(x, y)).At the point P (1/2 -√2),x = 1 / 2, y = - √2We will substitute these values in equations (1) and (2)

f'x (x, y) = 8x / (1 + 4x^2 + 6y^2)

1. Indefinite Integral: To find the indefinite integral of sech² (3x) dx, let us proceed with the steps below: Let y = sech² (3x) dx We know that sech x = 1 / cosh x= 2 / [ e^x + e^(-x)] So, sech² x = (2 / [ e^x + e^(-x)])²= 4 / [e^(2x) + 2 + e^(-2x)]

Therefore, y = 4 / [e^(2(3x)) + 2 + e^(-2(3x))]dx

= 4 / [e^(6x) + 2 + e^(-6x)]dx

Let u = e^(6x)u²

= e^(12x)du

= 6e^(6x)dx

So, we can rewrite the expression as,

y = 4 / [(u² / u²) + 2(u / u²) + 1]

= 4 / [u² + 2u + 1 - u²]

= 4 / [(u + 1)² - 1]

Substituting the value of u back, we get the final expression as:

y = 4 / [(e^(6x) + 1)² - 1]

Now, using the formula of integration, we can write,

∫ sech² (3x) dx

= ∫ 4 / [(e^(6x) + 1)² - 1] dx

= 2 / tanh (3x + C),

where C is a constant of integration.

2. Derivative of the Function:

To find the derivative of y

= tanh-¹ (sin 2x),

let us first find the derivative of tanh y

=y

=tanh^-1 (sin 2x)We know that tanh y

= sin 2xWe know that sech² y dy/dx

=[tex]2 cos 2xdy/dx[/tex]

=[tex]2 cos 2x / sech² ydy/dx[/tex]

= [tex]2 cos 2x / (1 - tanh² y)dy/dx[/tex]

= [tex]2 cos 2x / [1 - sin² (tanh y)][/tex]

Now, we can use the identity, sin² a + cos² a

= 1 and

sin² a

= tanh² b, to get,

dy/dx

=[tex]2 cos 2x / [1 - tanh² (tanh^-1 (sin 2x))]dy/dx[/tex]

=[tex]2 cos 2x / [1 - sin² (2x)]dy/dx[/tex]

=[tex]2 cos 2x / cos² (2x)dy/dx[/tex]

[tex]= 2 / cos (2x)[/tex]

= 2 sec (2x)

Hence, the derivative of y

= tanh-¹ (sin 2x) is dy/dx

= 2 sec (2x).

3. Indefinite Integral:

To find the indefinite integral of, let us proceed with the steps below:

Let y = (sin³x)(cos x) dx

We know that sin³ x

= sin² x * sin xWe also know that sin

2x = 2 sin x cos xsin² x

= (1 - cos 2x) / 2

Therefore, sin³ x

= (1 - cos 2x) / 2 * sin x

So, y = (1 - cos 2x) / 2 * sin x * cos x dx

= 1/4 sin 2x - 1/2 ∫ cos² x sin x dx

Now, we can use the formula, d/dx [sin x]

= cos x, to get,

[tex]∫ cos² x sin x dx[/tex]

= - 1/2 ∫ sin x d(cos x)

[tex]=- 1/2 sin x cos x + 1/2 ∫ cos x d(sin x)= - 1/2 sin x cos x + 1/2 sin² x+ C[/tex]

= [tex]1/2 sin x (sin x - cos x) + C[/tex]

Now, substituting this back to y, we get the final expression as,∫ (sin³ x)(cos x) dx= 1/4 sin 2x - 1/2 ∫ cos² x sin x dx= 1/4 sin 2x - 1/2 [1/2 sin x (sin x - cos x)]+ C= 1/4 sin 2x - 1/4 sin x (sin x - cos x) + C, where C is a constant of integration.

The number of units that must be produced and sold in order to yield the maximum profit is 14 units. Therefore, the correct answer is "14 units."

To find the number of units that must be produced and sold in order to yield the maximum profit, we need to determine the quantity that maximizes the profit function. The profit function is calculated by subtracting the cost function from the revenue function: P(x) = R(x) - C(x).

Given the revenue function R(x) = 20x - 0.5x^2 and the cost function C(x) = 6x + 5, we can substitute these equations into the profit function:

P(x) = (20x - 0.5x^2) - (6x + 5)

P(x) = 14x - 0.5x^2 - 5

To find the maximum profit, we take the derivative of the profit function with respect to x and set it equal to zero: P'(x) = 14 - x = 0 x = 14

So, the number of units that must be produced and sold in order to yield the maximum profit is 14 units. Therefore, the correct answer is "14 units."

Answer:

The maximum value f(4) can have is 70

f(4) = 70

Step-by-step explanation:

For the largest possible value, the derivative must be greatest,

so, for our case, since f'(x) ≤ 9,

but for largest value, f'(x) must be greatest, hence it must be,

f'(x) = 9.

With this derivative,

Using the value,

f(-3) = 7,

with each step, we increase by 9 units

so, f(-2) = f(-3) + 9 = 7 + 9 = 16

f(-2) = 16

going till f(4),

f(-1) = 16+9

f(-1) = 25

f(0) = 25 + 9 = 34

f(1) = 34 + 9 = 43

f(2) = 43 = 9 = 52

f(3) = 52 + 9 = 61

The inverse DFT of the resulting product to obtain the convolution y[n].

a) To compute y[n] = x[n] * h[n] using a 5-point DFT, we can follow these steps:

Pad x[n] and h[n] with zeros to make them of length 5, if necessary. In this case, both x[n] and h[n] are already of length 5, so no padding is required.

Take the DFT of x[n] and h[n] using a 5-point DFT algorithm. You can use algorithms like the Cooley-Tukey algorithm or any other efficient DFT algorithm to compute the DFT.

Multiply the corresponding frequency components of x[n] and h[n] element-wise.

Take the inverse DFT of the resulting product to obtain y[n].

However, in this case, x[n] has length 5 and h[n] has length 3. To perform linear convolution, the lengths of x[n] and h[n] should be the sum of their individual lengths minus one. In this case, the length of y[n] should be 5 + 3 - 1 = 7. Since the DFT requires the input sequences to have the same length, we cannot directly compute y[n] using a 5-point DFT.

b) To compute the convolution of x[n] and h[n] using a 10-point DFT, we can follow these steps:

Pad x[n] and h[n] with zeros to make them of length 10. Pad x[n] with 5 zeros at the end and h[n] with 7 zeros at the end.

Take the DFT of x[n] and h[n] using a 10-point DFT algorithm.

Multiply the corresponding frequency components of x[n] and h[n] element-wise.

Take the inverse DFT of the resulting product to obtain the convolution y[n].

The center of mass is an average location of all the points in an object. This point also represents the point at which the object can be perfectly balanced.

The center of mass of a body is the point at which the total mass of the system is concentrated. It is an important quantity in physics and engineering and is used to determine the behavior of objects when they are subjected to forces.

[tex]Let p= x^3 + xe^-x  for x € (0, 1),[/tex]

compute the center of mass We can compute the center of mass of p= x^3 + xe^-x  for x € (0, 1) using the formula given below,[tex]`{x_c = (1/M)*int_a^b(x*f(x))dx}` where `x_c[/tex]` is the center of mass, `M` is the mass of the system, `a` and `b` are the limits of integration, and `f(x)` is the density function of the system.

[tex]`x_c = (1/M)*int_0^1(x*p(x))dx`. Substituting the values we obtained for `M` and `int_0^1(x*p(x))dx`, we get:`x_c = [(1/4) - (1/2)e^-1]/[-(1/4) + (1/2)e^-1] = (1/2) - (1/2)e^-1`[/tex]

I understand the instructions and will distribute the points in a way that maximizes the total earned for both participants. Here is how I would allocate the points:

KEEP account: 0 points

GIVE account: 10 points

By allocating all 10 points to the GIVE account, both participants will receive 15 points after the 50% multiplier is applied (10 * 1.5 / 2 = 15). This results in the highest total score compared to any other allocation.

Therefore, the given equation is true and we have successfully proved that the first side is equal to the second side.

Given, A + (AB) = A + B

First we take LHS, then expand using distributive property:

A + (AB) = A + B

=> A + AB = A + B

=> AB = B

Subtracting B from both the sides we get:

AB - B = 0

=> B (A - 1) = 0

So, either B = 0 or (A - 1) = 0.

If B = 0, then both sides are equal as 0 equals 0.

If (A - 1) = 0, then A = 1.

Substituting A = 1, the given equation is rewritten as:(1 + B) = 1 + B => 1 + B = 1 + B

Thus, both sides are equal.

Hence, we can say that the first side is equal to the second side.

Proof: A + (AB) = A + B(1 + B) = 1 + B [As we have proved it in above steps]

The, (overline{DF} ) has a length of ( sqrt{74} ) units in case (b).

To find the length of (overline {DF} ) in both cases, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

(a) Given ( DE = 16) and ( EF = 12 ), we can find ( DF ) using the Pythagorean theorem:

\[ DF^2 = DE^2 + EF^2 \]

\[ DF^2 = 16^2 + 12^2 \]

\[ DF^2 = 256 + 144 \]

\[ DF^2 = 400 \]

Taking the square root of both sides, we get:

[ DF = sqrt{400} = 20 ]

Therefore, (overline{DF} ) has a length of 20 units in case (a).

(b) Given ( DE = 7 ) and ( EF = 5 ), we can apply the Pythagorean theorem again to find ( DF ):

\[ DF^2 = DE^2 + EF^2 \]

\[ DF^2 = 7^2 + 5^2 \]

\[ DF^2 = 49 + 25 \]

\[ DF^2 = 74 \]

Taking the square root of both sides, we have:

[ DF =sqrt{74} ]

Therefore, (overline{DF} ) has a length of (sqrt{74} ) units in case (b).

The coordinates of the equilibrium point are (70, 2600).

To find the equilibrium point, we need to set the consumer willingness to pay equal to the producer willingness to accept. In other words, we need to find the value of x that makes D(x) equal to S(x).

Given:

D(x) = 4000 - 20x

S(x) = 850 + 25x

Setting D(x) equal to S(x), we have:

4000 - 20x = 850 + 25x

To solve this equation, we can combine like terms:

45x = 4000 - 850

45x = 3150

Now, divide both sides by 45 to isolate x:

x = 3150 / 45

x = 70

So the equilibrium quantity is 70 units.

To find the equilibrium price, we substitute this value of x back into either D(x) or S(x). Let's use D(x) = 4000 - 20x:

D(70) = 4000 - 20(70)

D(70) = 4000 - 1400

D(70) = 2600

Therefore, the equilibrium price is $2600 per unit.

The coordinates of the equilibrium point are (70, 2600).
