Ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth? 0.5 m/s2 4.9 m/s2 8.5 m/s2 9.8 m/s2

Answers

Answer 1

The option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".

What is mass?

A tangible body's mass is the amount of matter it possesses. It's also a metric of inertial, or the resistance to velocity when a net force is exerted.

The question is incomplete.

The complete question is:

A box that has a mass of 80 kg slides down a ramp with a 30-degree angle. The free-body diagram shows the forces acting on the box. Ignoring friction and air resistance, what is the acceleration of the box, to the nearest tenth?

-0.5 m/s²

-4.9 m/s²

-8.5 m/s²

-9.8 m/s²

First we calculate the weight:

W = mg = 80×9.8

W = 784 N

The weight component parallel to the ramp is:

W₁ = Wsin30

W₁ = (784)(sin30)

W₁ = 392 N

From the Newton's second law:

a = F/m

a = 392/80

a = 4.9 m/s²

Thus, the option second -4.9 m/s² is correct the negative sign shows that a positive direction "upward along the ramp".

Therefore, all possible results are (0,1,0,0),(1,0,1,0),(1,0,0,1),(0,1,1,1)
Would this be correct?

Answers

The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).

Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.

Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).

Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).

Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).

To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.

(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)

Expanding this expression, you get:

(0+a+b, 1+a+b, 0+a, 0+b)

Simplifying, you obtain the following set of solutions:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Therefore, the correct set of possible results would be:

(0, 1, 0, 0)

(1, 2, 1, 0)

(1, 2, 0, 1)

Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

The owner of a retail store is tracking his inventory for an annual report. The graph shows the remaining Inventory for a particular item and the
number of days that have passed since the stock was replenished.

Which type of function best models the relationship between the number of days and the inventory remaining?

The owner of a retail store is tracking his inventory for an annual report. The graph shows the remaining

Answers

Answer:

y = -2.8x +69.4

Step-by-step explanation:

Let y represent units of inventory, and x represent days since the last replenishment. We are given points (x, y) = (3, 61) and (13, 33). The line through these points can be described using the 2-point form of the equation of a line:

... y -y1 = (y2-y1)/(x2 -x1)(x -x1)

Filling in the given point values, we have ...

... y -61 = (33 -61)/(13 -3)(x -3)

Simplifying and adding 61, we get ...

... y = -2.8x +69.4

The linear function which best models the relationship between the number of days and remaining inventory is \(y = \frac{-35}{12}x + \frac{50}{3}\) .

What is linear function?

A linear function refers to when the dependent variable (usually expressed by 'y') changes by a constant amount as the independent variable (usually 'x') also changes by a constant amount.

According to the given equation

We have a graph which shows the remaining inventory.

In which x represents the number of days and y represents the inventory remaining.

Let y = mx + b be the linear function which represents the relationship between the number of days and the inventory remaining.

Form the given graph if we choose two points (14, 30) and (2, 65) for finding the value of m and b.

Substitute y = 30 and x = 14 in y = mx + b

⇒ \(30 = m(14) + b...(i)\)

Similarly,

substitute y =65 and x =2 in y = mx + b

⇒\(65 = 2m + b..(ii)\)

From equation (i) and (ii)

\(m = \frac{-35}{12}\)

and \(\frac{50}{3}\)

Therefore, \(y = \frac{-35}{12}x + \frac{50}{3}\)

Hence, the linear function which best models the relationship between the number of days and remaining inventory is \(y = \frac{-35}{12}x + \frac{50}{3}\) .

What is nonexperimental research?

Research without either the manipulation of an independent variable, the random assignment of individuals to conditions or orders of conditions, or both, is referred to as non-experimental research.

The non-experimental study is entirely dependent on variables that the researcher has no control over. By whatever means, they cannot manipulate, control, or change the subjects. Thus, all they can do is continue their research while monitoring and interpreting their subjects.

It is safe to assume that a non-experimental research design is used when there is no specific cause-effect study problem and the researcher simply wants to grasp a topic in depth without constraining it with variables. They examine the natural phenomena as they take place.

Using this formula, calculate the slope for each given points

a. (9, 10) and (7, 2)

slope (m) = (2 - 10) / (7 - 9)

So, the slope is 6/7.

c. (5, -6) and (2, 3)

slope (m) = (3 - (-6)) / (2 - 5)

En una caja de cartón se empacan 400 latas de atún al acomodarlas resultan que caben 5 latas más a lo largo que a lo ancho y a lo alto caben 3 latas más que a lo ancho ¿Cuántas latas en total tocan el fondo de la caja?

Answers

Answer:

Hay 50 latas en total que tocan el fondo de la caja.

Step-by-step explanation:

Una caja de cartón es representada por un cuadrilátero, cuyas caras son rectángulos. Si la caja esta ocupada por completo, entonces la cantidad total de latas es representada por la siguiente expresión:

\(n_{V} = n_{w}\cdot n_{h}\cdot n_{l}\) (1)

Donde:

\(n_{V}\) - Total de latas de atún, adimensional.

\(n_{w}\) - Cantidad de latas de atún a lo ancho de la caja, adimensional.

\(n_{h}\) - Cantidad de latas de atún a lo alto de la caja, adimensional.

\(n_{l}\) - Cantidad de latas de atún a lo largo de la caja, adimensional.

De acuerdo con el enunciado, tenemos las siguientes relaciones:

\(n_{V} = 400\) (2)

\(n_{l} = n_{w} +5\) (3)

\(n_{h} = n_{w}+3\) (4)

Si aplicamos estas fórmulas a (1), tenemos el siguiente polinomio de tercer orden:

\(n_{w} \cdot (n_{w}+5)\cdot (n_{w}+3) = 400\)

\(n_{w}\cdot (n_{w}^{2}+8\cdot n_{w}+15) = 400\)

\(n_{w}^{3}+8\cdot n_{w}^{2}+15\cdot n_{w} -400 = 0\)

Este polinomio se puede resolver por vía analítica por el Método de Cardano o por vía numérica, sus raíces son:

\(n_{w,1} = 5\), \(n_{w,2} = -6.5+i\,6.144\), \(n_{w,3} = -6.5-i\,6.144\)

En consecuencia, la única solución válida es \(n_{w} = 5\) y las variables restantes son por (3) y (4):

\(n_{l} = 10\) y \(n_{h} = 8\)

La cantidad de latas que tocan el fondo de la caja es igual al producto de la cantidad de latas a lo largo de la caja y la cantidad de latas a lo ancho de la caja, es decir:

\(n_{A} = n_{w}\cdot n_{l}\) (5)

\(n_{A} = (5)\cdot (10)\)

\(n_{A} = 50\)

Hay 50 latas en total que tocan el fondo de la caja.

Answers

Division is one of the most basic arithmetical operators. The amount that Alejandro need to save for each month is $375.

What is division?

The division is one of the most basic arithmetical operators. When we divide a number (P) by another number(q), then it tells us how many times the other number(q) must be added to itself to form the first number(P).

It is given that the cost of tuition for the two years is $12,000, while the financial aid that Alejandro is eligible for is $7500, therefore, the amount that he will not be able to pay with his scholarship(financial aid) will be the difference in the fees of the student and the financial aid he is getting.

Difference = Two-year tuition fees - Financial Aid

                 = $12,000 - $7,500

                  = $4,500

Now, since Alejandro needs to save for a year so the sum he saves is $4500 therefore, the amount he needs to save each month can be written as,

\(\text{Amount Alehjandro needs to save each moth}=\dfrac{\text{Amount that Alejandro need to save}}{\text{Number of months he needs to save}}\)

\(\text{Amount Alehjandro needs to save each moth}=\dfrac{4500}{12} = \$375\)

Hence, the amount that Alejandro need to save for each of the month so that he can pay his tuition fee is $375.

Answers

The orthogonal projection of [-2,2] onto the line passing through the origin and the point [-1,5] is the point [0.9231, 4.6154].

Orthogonal projection is a concept in linear algebra that allows us to find the closest point on a line to a given point.

To find the orthogonal projection of the point [-2,2] onto this line, we need to find the point on the line that is closest to the given point.

This line will be the line passing through the given point and perpendicular to the given line.

So, the projection of the given point [-2,2] onto the line passing through the origin and the point [-1,5] is given by the formula:

proj_l([-2,2]) = (([-2,2] . [-1,5]) / ([-1,5] . [-1,5])) x [-1,5]

where . represents the dot product of two vectors.

Evaluating this formula, we get:

proj_l([-2,2]) = (-12/26) x [-1,5]

The unitary technique, in its most basic form, is used to calculate the value of a single unit from a specified multiple. The unitary approach can be used to complete it. Additionally, after determining the value of a single unit, we can multiply that value by the number of units needed to determine the value of the additional units. The concept of ratio and proportion is mostly applied using this way.

Given, for every 3 pencils, number of pens bought = 2
Therefore, every 1 pencil, number of pens bought = 2/3
Thus, for 21 pencils, number of pens bought = (2/3)*21 = 14
Therefore, total number of pencils and pens bought by Henry = 21 + 14 = 35.

What is a segment?

A line segment includes all the points on the line between two clearly defined endpoints and is part of a line. As a one-dimensional object, a segment has only length and neither breadth nor height.

The formula for distance between two locations in a two-dimensional coordinate system, (x1, y1) and (x2, y2), is as follows:

d = \(\sqrt{x} [(x2 - x1)^2 + (y2 - y1)^2]\)

Here, the two ends of the segment are (3,-4) and (3,-17).

In this equation, predict

x₁ = 3 , y₁ = - 4 , x₂ = 3 , y₂ = - 17

We need to calculate the distance between these two locations in order to determine the segment's length:

d = \(\sqrt{x} [(3 - 3)^2 + (-17 - (-4))^2]\)

= \(\sqrt{x} [0 + (-13)^2]\)

d° + 15° + 45° = 180°

d° = 180° - 60°

d° = 120°

for angle e; (the Supplementary angles)

(e - 27°) + d° + 15° = 180°  (put value of d)

e - 27° + 120° + 15° = 180°

e° = 72°

for angle f; (the Supplementary angles)

(6f)° + 45° + 15°  = 180°

(6f)° = 120°

f° = 20°

for angle g; (the Supplementary angles)

(g-86)° + (6f)° + 45° = 180°      (put value of f)

(g-86)° + (6×20)° + 45° = 180°

(g-86)° + 120° + 45° = 180°

g° = 101°

Therefore, the angles of d° is 120°, e° is 72°,  f° is 20° and g° is 101°

use the gradient to find the directional derivative of the function at p in the direction of pq. g(x, y, z) = xye4z, p(5, 20, 0), q(0, 0, 0)

Answers

the directional derivative of the function g(x, y, z) = xye^(4z) at point p(5, 20, 0) in the direction of pq is given by: (-1/5)(ye^(4z)) + (-4/5)(xe^(4z))

To find the directional derivative of the function g(x, y, z) = xye^(4z) at point p(5, 20, 0) in the direction of pq, we need to compute the gradient of g and then take the dot product with the unit vector in the direction of pq.

First, let's find the gradient of g(x, y, z):

∇g = (∂g/∂x, ∂g/∂y, ∂g/∂z)

Taking partial derivatives:

∂g/∂x = ye^(4z)

∂g/∂y = xe^(4z)

∂g/∂z = 4xye^(4z)

So, the gradient vector ∇g is:

∇g = (ye^(4z), xe^(4z), 4xye^(4z))

Next, we need to find the direction vector pq. The direction vector from p to q is given by:

pq = q - p = (0 - 5, 0 - 20, 0 - 0) = (-5, -20, 0)

To calculate the directional derivative, we take the dot product of the gradient vector ∇g and the unit vector in the direction of pq:

Directional derivative = ∇g · (pq / ||pq||)

where ||pq|| is the magnitude of the vector pq.

First, let's find the magnitude of pq:

||pq|| = sqrt((-5)^2 + (-20)^2 + 0^2) = sqrt(625) = 25

Now, let's calculate the directional derivative:

∇g · (pq / ||pq||) = ∇g · (-5/25, -20/25, 0/25)

                   = ∇g · (-1/5, -4/5, 0)

                   = (-1/5)(ye^(4z)) + (-4/5)(xe^(4z)) + 0

Therefore, the directional derivative of the function g(x, y, z) = xye^(4z) at point p(5, 20, 0) in the direction of pq is given by:

(-1/5)(ye^(4z)) + (-4/5)(xe^(4z))
