Answers

Answer 1

The maximum altitude attained by the projectile is 720 meters.  The maximum altitude was achieved by the projectile when time expressed in seconds and rounded off to four significant figures was equal to 10.89 seconds.

The formula for the altitude y of the projectile at the moment of time t is given by the formula: y(t) = [(v_0 / p)g][1 - exp(-pt / m)] + (m / p)g(t / p) where v_0 is the initial velocity of the projectile, p is the empirical constant, g is the acceleration due to gravity, m is the mass of the projectile, and t is the time.

The formula for the velocity of the projectile at the moment of time t is given by the formula: v(t) = (v_0 / p)exp(-pt / m) + (m / p)g.

Any object launched into space with only gravity acting on it is referred to as a projectile. Gravity is the main force affecting a projectile. This doesn't imply that other forces don't affect it; it merely means that their impact is far smaller than that of gravity. A projectile's trajectory is its route after being fired. A projectile is something that is launched or batted, as a baseball.

Answer:

Where is the question tho whaaAAaaaa

Two particles, Alpha and Beta, race from the y-axis to the vertical line x = 6*pi. For t >= 0, Alpha's position is given by the parametric equations xalpha = 3t - 4sin(t) and yalpha = 3 - 3cos(t) while Beta's position is given by xbeta = 3t - 4sin(t) and ybeta = 3 - 4sin(t). Which sentence best describes the race and its outcome?
(A) Beta starts out in the wrong direction and loses.
(B) Alpha takes a shorter path and wins.
(C) Alpha moves slower and loses.
(D) Beta moves faster but loses.
(E) Alpha and Beta tie

Answers

The outcome of the race between Alpha and Beta, as described by their parametric equations, is that Beta moves faster but loses. Although Beta has a higher speed, Alpha consistently maintains a higher vertical position, leading to Alpha winning the race.

To determine the outcome of the race between Alpha and Beta, let's compare their positions using the given parametric equations:

Alpha's position:

[tex]x_{alpha} = 3t - 4sin(t)\\y_{alpha}= 3 - 3cos(t)[/tex]

Beta's position:

[tex]x_{beta} = 3t - 4sin(t)\\y_{beta} = 3 - 4sin(t)[/tex]

From the equations, we can see that the x-coordinate of both Alpha and Beta is the same, given by 3t - 4sin(t). Therefore, their horizontal positions are identical throughout the race.

To determine the vertical positions, we compare their y-coordinates. Alpha's y-coordinate is given by 3 - 3cos(t), while Beta's y-coordinate is given by 3 - 4sin(t).

Since cos(t) ranges from -1 to 1, and sin(t) ranges from -1 to 1, we can observe the following:

For Alpha, the y-coordinate (3 - 3cos(t)) ranges from 0 to 6, inclusive.

For Beta, the y-coordinate (3 - 4sin(t)) ranges from 2 to 4, inclusive.

Based on the range of their y-coordinates, we can conclude that Beta remains at a higher position throughout the race. Therefore, the correct answer is:

(D) Beta moves faster but loses.

Despite Beta moving faster, it loses the race because Alpha consistently maintains a higher vertical position.

Therefore, the outcome of the race between Alpha and Beta, as described by their parametric equations, is that Beta moves faster but loses. Although Beta has a higher speed, Alpha consistently maintains a higher vertical position, leading to Alpha winning the race.

Step-by-step explanation:

Solve the following problem using Simplex Method: MAX Z=6X1 + 10X2 + 5 X3 ST X1 + 2X2 + 4X3 <=8 6X1 + 4X2 <=24 6X1 + 5X3 <=30 X1,X2,X3 >=0

Answers

The maximum value of the objective function Z is 120. The optimal values for the decision variables are X1 = 8, X2 = 0, and X3 = 0. The constraints are satisfied, and the optimal solution has been reached using the Simplex Method.

To compute the problem using the Simplex Method, let's convert it into standard form.

Maximize:

Z = 6X1 + 10X2 + 5X3

Subject to the constraints:

X1 + 2X2 + 4X3 <= 8

6X1 + 4X2 <= 24

6X1 + 5X3 <= 30

X1, X2, X3 >= 0

Introducing slack variables S1, S2, and S3 for each constraint, the constraints can be rewritten as equalities:

X1 + 2X2 + 4X3 + S1 = 8

6X1 + 4X2 + S2 = 24

6X1 + 5X3 + S3 = 30

Now, we have the following equations:

Objective function:

Z = 6X1 + 10X2 + 5X3 + 0S1 + 0S2 + 0S3

Constraints:

X1 + 2X2 + 4X3 + S1 = 8

6X1 + 4X2 + S2 = 24

6X1 + 5X3 + S3 = 30

X1, X2, X3, S1, S2, S3 >= 0

Next, we will create the initial simplex tableau:

  | X1 | X2 | X3 | S1 | S2 | S3 | RHS |

---------------------------------------

Z  | 6  | 10 | 5  | 0  | 0  | 0  | 0   |

---------------------------------------

S1 | 1  | 2  | 4  | 1  | 0  | 0  | 8   |

---------------------------------------

S2 | 6  | 4  | 0  | 0  | 1  | 0  | 24  |

---------------------------------------

S3 | 6  | 0  | 5  | 0  | 0  | 1  | 30  |

---------------------------------------

By performing the simplex pivot operations and iterating through the simplex method steps, we find the following tableau:

  | X1 | X2 | X3 | S1 | S2 | S3 | RHS |

---------------------------------------

Z  | 0  | 0  | 5  | -6 | 0  | -60| 120 |

---------------------------------------

X1 | 1  | 2  | 4  | 1  | 0  | 0  | 8   |

---------------------------------------

S2 | 0  | -8 | -24| -6 | 1  | 0  | 0   |

---------------------------------------

S3 | 0  | 0  | -1 | -6 | 0  | 1  | 0   |

---------------------------------------

The optimal solution is Z = 120, X1 = 8, X2 = 0, X3 = 0, S1 = 0, S2 = 0, S3 = 0.

Therefore, the maximum value of Z is 120, and the values of X1, X2, and X3 that maximize Z are 8, 0, and 0, respectively.

Answers

The value of the integral is 15.87.

The given integral is:∫∫R 10(x+y) dAwhere R={(x,y)∣16≤x²+y²≤25,x≤0} in rectangular coordinates.In rectangular coordinates, the equation of circle is x²+y² = r², where r is the radius of the circle and the equation of the circle is given as: 16 ≤ x² + y² ≤ 25 ⇒ 4 ≤ r ≤ 5We need to evaluate the integral over the region R using rectangular coordinates and integrate first with respect to x and then with respect to y.∫∫R 10(x + y) dA = 10∫ from 4 to 5 ∫ from -√(25-y²) to -√(16-y²) (x+y) dx dy...[since x < 0]

Now, integrating ∫(x+y) dx we get ∫(x+y) dx = (x²/2 + xy)Therefore, 10∫ from 4 to 5 ∫ from -√(25-y²) to -√(16-y²) (x+y) dx dy = 10∫ from 4 to 5 ∫ from -√(25-y²) to -√(16-y²) [ (x²/2 + xy) ] dy dx= 10∫ from 4 to 5 [∫ from -√(25-y²) to -√(16-y²) (x²/2 + xy) dy] dxNow integrating with respect to y we get∫(x²/2 + xy) dy = (xy/2 + y²/2)

Putting the limits and integrating we get10∫ from 4 to 5 [∫ from -√(25-y²) to -√(16-y²) (x²/2 + xy) dy] dx = 10∫ from 4 to 5 [(∫ from -√(25-y²) to -√(16-y²) (x²/2 + xy) dy)] dx = 10∫ from 4 to 5 [(x²/2)[y]^(-√(16-x²) )_(^(-√(25-x²))] + [(xy/2)[y]^(-√(16-x²) )_(^(-√(25-x²)))] dx = 10∫ from 4 to 5 [-(x²/2)√(16-x²) + (x²/2)√(25-x²) - (x/2)(16-x²)^(3/2) + (x/2)(25-x²)^(3/2) ] dxNow integrating with respect to x, we get10∫ from 4 to 5 [-(x²/2)√(16-x²) + (x²/2)√(25-x²) - (x/2)(16-x²)^(3/2) + (x/2)(25-x²)^(3/2) ] dx = [ (10/3) [(25/3)^(3/2) - (16/3)^(3/2)] - 5√3 - (5/3)[(25/3)^(3/2) - (16/3)^(3/2) ] ]Ans: The value of the integral is 15.87.

A rubber ball is dropped from a height of 26 feet, and on each bounce it rebounds up 62% of its previous height. Step 2 of 2: Assuming the ball bounces indefinitely, find the total vertical distance traveled. Round your answer to two decimal places.

Answers

The total vertical distance traveled by the rubber ball, assuming it bounces indefinitely, is approximately 85.71 feet.

To find the total vertical distance traveled, we need to sum up the heights achieved by the ball during each bounce. The ball initially drops from a height of 26 feet, so we start with this value. On each bounce, the ball rebounds up 62% of its previous height. This means that after the first bounce, the ball reaches a height of 26 feet * 0.62 = 16.12 feet.

For subsequent bounces, we continue to multiply the previous height by 0.62 to find the new height. Therefore, after the second bounce, the height becomes 16.12 feet * 0.62 = 9.99 feet.

We can see that the heights achieved during each bounce form a geometric sequence with a common ratio of 0.62. The sum of an infinite geometric sequence can be calculated using the formula,

Sum = a / (1 - r), first term is a and 'r' is the common ratio is r.

In this case, 'a' is the initial height of 26 feet and 'r' is 0.62. Plugging these values into the formula, we get,

Sum = 26 / (1 - 0.62) = 26 / 0.38 ≈ 68.42 feet.

Therefore, adding all the distances,

Distance = 68.42 + 9.99 + 16.12

Distance = 85.71 feet, total vertical distance traveled by the rubber ball, rounded to two decimal places, is approximately 85.71 feet.

For the function f(x,y) = 3x^7 + 4y^7 + 12, f_xy = f_yx since fx = ______ and fy = ____

Therefore, fxy= _______ and fyx = _______

Answers

Given the function: f(x,y) = 3x^7 + 4y^7 + 12To verify that f_xy = f_yx, we need to find the partial derivatives of the given function with respect to x and y. We can find them as follows: ∂f/∂x = 21x^6 ∂f/∂y = 28y^6

Now, to verify that f_xy = f_yx, we need to find f_xy and f_yx. We can find them as follows: f_xy = ∂^2f/∂y∂x = ∂/∂y(∂f/∂x) = ∂/∂y(21x^6) = 0 (since we have no y terms in the derivative of ∂f/∂x) f_yx = ∂^2f/∂x∂y = ∂/∂x(∂f/∂y) = ∂/∂x(28y^6) = 0 (since we have no x terms in the derivative of ∂f/∂y)Since f_xy = f_yx = 0, we can say that f_xy = f_yx.

Therefore, the value of fx is 21x^6 and the value of fy is 28y^6. Hence, the value of fxy is 0 and fyx is also 0.

Find m so that x + 4 is a factor of 5x3 + 18x2 + mx + 16

Answers

The value of 'm' for which (x + 4) is a factor of the polynomial [tex]5x^3 + 18x^2 + mx + 16[/tex] is -4.

To find the value of 'm' for which the expression (x + 4) is a factor of the polynomial[tex]5x^3 + 18x^2 + mx + 16[/tex], we can apply the factor theorem. According to the factor theorem, if (x + 4) is a factor of the polynomial, then the polynomial evaluated at (-4) should be equal to zero.

Substituting (-4) into the polynomial, we get:

[tex]5(-4)^3 + 18(-4)^2 + m(-4) + 16 = 0[/tex]

-320 + 288 + (-4m) + 16 = 0

-16 + (-4m) = 0

Simplifying the equation, we have:

-4m - 16 = 0

-4m = 16

m = 16 / -4

m = -4

Therefore, the value of 'm' for which (x + 4) is a factor of the polynomial [tex]5x^3 + 18x^2 + mx + 16[/tex] is -4.

By substituting -4 for 'm' in the given polynomial, we obtain:

[tex]5x^3 + 18x^2 - 4x + 16[/tex]

When this polynomial is divided by (x + 4), the remainder will be zero, confirming that (x + 4) is indeed a factor.

(b) lim(z→-1) (1 + √(2 - 2z + z²))/(2 - iz - 1) = ((1 + √(5))(3 - i))/10

(a) To find the limit of lim(x→0) 4x/(x² + 1), we can directly substitute 0 for x in the expression:

lim(x→0) 4x/(x² + 1) = (4 × 0)/(0² + 1) = 0/1 = 0

Therefore, the limit is 0.

(b) To find the limit of lim(z→-1) (1 + √(2 - 2z + z²))/(2 - iz - 1), we can again substitute -1 for z in the expression:

lim(z→-1) (1 + √(2 - 2z + z²))/(2 - iz - 1) = (1 + sqrt(2 - 2(-1) + (-1)^2))/(2 - i(-1) - 1)

= (1 + √(2 + 2 + 1))/(2 + i + 1)

= (1 + √(5))/(3 + i)

To simplify this expression further, we need to rationalize the denominator. We can multiply the numerator and denominator by the conjugate of the denominator, which is (3 - i):

lim(z→-1) (1 + √(5))/(3 + i) × (3 - i)/(3 - i)

= ((1 + √(5))(3 - i))/(9 - i²)

= ((1 + √(5))(3 - i))/(9 + 1)
