A rock is projected from the edge of the top of a building with an initial velocity of 12. 2 m/s at an angle of 63° above the horizontal. The rock strikes the ground a horizontal distance of 25 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. What is the time?.

Answers

Answer 1

The rock travels a horizontal distance x after time t of

x = (12.2 m/s) cos(63°) t

If it hits the ground 25 m away from where it was thrown, then for some time t we have

25 m = (12.2 m/s) cos(63°) t

Solve for t :

t = (25 m) / ((12.2 m/s) cos(63°))

t ≈ 4.5 s

Maximize the objective function p = 5x + 3y for the given constraints. X ≥ 0 y ≥ 0 3x + 6y ≤ 48 2x + 8y ≤ 56.

Answers

The maximized value of the objective function is 38

The objective function is given as:

Max P = 5x + 3y

The constraints are given as:

3x + 6y ≤ 48 2x + 8y ≤ 56x ≥ 0 y ≥ 0

To do this, we make use of the graphical method.

See attachment for the graph of the constraints.

From the graph, we have the following feasible point

[tex](x,y) = (4,6)[/tex]

Substitute 4 for x and 6 for y in the objective function.

[tex]Max\ P = 5x + 3y[/tex]

So, we have:

[tex]P = 5 \times 4 + 3 \times 6[/tex]

[tex]P = 20 + 18[/tex]

[tex]P = 38[/tex]

Hence, the maximized value of the objective function is 38

https://brainly.com/question/16826001

Answer:

Explanation:

If an objective function has a maximum value, it will occur at one of the vertices of the feasible region (i.e., the solution region for the system of inequalities). The feasible region's vertices occur at (0, 0), (0, 7), (4, 6), and (16, 0).

Use the x- and y-value from each vertex to evaluate the objective function P = 5x + 3y.

(x, y) 5x + 3y P

(0, 0) 5(0) + 3(0) 0

(0, 7) 5(0) + 3(7) 21

(4, 6) 5(4) + 3(6) 38

(16, 0) 5(16) + 3(0) 80

Therefore, the maximum of the objective function is 80.

Answers

The reference angle is the smallest angle between the terminal side and the x-axis.

[tex](1)\ \theta = 300^o[/tex]

300 degrees is in the 4th quadrant.

So, the reference angle is

[tex]\alpha = 360 - \theta[/tex]

[tex]\alpha = 360 - 300[/tex]

[tex]\alpha = 60^o[/tex]

Hence, the reference angle of 300 degrees is 60 degrees

[tex](2)\ \theta = 225^o[/tex]

225 degrees is in the 3rd quadrant.

So, the reference angle is

[tex]\alpha = \theta - 180[/tex]

[tex]\alpha = 225 - 180[/tex]

[tex]\alpha = 45^o[/tex]

Hence, the reference angle of 225 degrees is 45 degrees

[tex](3)\ \theta = 480^o[/tex]

480 degrees is in the 2nd quadrant (i.e. 480 - 360 = 120)

So, the reference angle is

[tex]\alpha = 180 - \theta[/tex]

[tex]\alpha = 180 - 120[/tex]

[tex]\alpha = 60^o[/tex]

Hence, the reference angle of 480 degrees is 60 degrees

[tex](2)\ \theta = -210^o[/tex]

-210 degrees is in the 2nd quadrant (i.e. 360 - 210 = 150)

So, the reference angle is

[tex]\alpha = 180 - \theta[/tex]

[tex]\alpha = 180 - 150[/tex]

[tex]\alpha = 30^o[/tex]

Hence, the reference angle of -210 degrees is 30 degrees

Answers

Answer:

the answer is evaporation

Explanation: Evaporation is the process by which a liquid transforms into vapor (a gas). When some material is in its liquid phase, its particles are really close together (but not as much as we would see in a metal). As the temperature of the liquid increases, also does the kinetic energy of the particles. This cause the particles in the water to move a lot faster, thus its oscillations are larger. This causes an increase in the volume of the material.

The origin of Christianity in America started with the Europeans. The Europeans like Spain, France, England, and the Netherlands brought different forms of Christian practice to America.

During this period, the Europeans settled in America and quickly spread Christianity among themselves and the Native Americans due to their superior warfare.

Unlike other regions that have many natives with different religious beliefs, America mainly was populated with few natives, thereby making Christianity increase in the region when many Europeans came.

Hence, in this case, it is concluded that the correct answer is America.

What is the approximate tangential speed of an object orbiting earth with a radius of 1. 8 × 108 m and a period of 2. 2 × 104 s? 7. 7 × 10–4 m/s 5. 1 × 104 m/s 7. 7 × 104 m/s 5. 1 × 105 m/s.

Answers

Answer: the period is 2.2 x 104 s, then the rotational speed is:

1 / 2.2x104 = 4.55x10-5 rad/s

We can solve for the tangential speed using the formula:

v = ωr

where ω is the rotational speed

v is the linear or tangential speed

r is the radius

So,

v = 4.55x10-5(1.8x108)

v = 5.1 x 104 m/s

Explanation:

The approximate tangential speed of an object orbiting earth with a radius of 1. 8 × 108 m is 5.1 x 104 m/s.

What is tangential speed?

Any item moving along a circular path has a linear component to its speed called tangential velocity.

An object's velocity is always pointed tangentially when it travels in a circle at a distance r from the center. Tangential velocity is the name given to this.

The period is 2.2 x 104 s, then the rotational speed is:

1 / 2.2 x 104 = 4.55 x 10⁻⁵ rad/s

We can solve for the tangential speed using the formula:

v = ωr

where ω is the rotational speed

v is the linear or tangential speed

r is the radius

So,

v = 4.55 x 10⁻⁵ (1.8 x 108)

v = 5.1 x 104 m/s

Therefore, the tangential velocity is 5.1 x 104 m/s.
