Final Answer:
Word done = 31 units
Explanation:
To find the work done by a force field [tex]$\mathbf{F}(x, y, z)$[/tex] on a particle moving along a path, we can use the line integral of the force field along that path.
First, we need to define the force field [tex]$\mathbf{F}(x, y, z)$[/tex] and the parametric equations for the line segment.
Given the force field
[tex]$$\mathbf{F}(x, y, z) = \langle y + z, x + z, x + y \rangle,$$[/tex]
we have the following components:
[tex]F_x &= y + z, \\\\F_y &= x + z, \\\\F_z &= x + y.[/tex]
Now, let's find the parametrization of the line segment from the point (1,0,0) to the point (5,3,2). We can define a vector [tex]$\mathbf{r}(t)$[/tex] that describes this line segment by
[tex]$$\mathbf{r}(t) = \mathbf{r_0} + t(\mathbf{r_1} - \mathbf{r_0}),$$[/tex]
where [tex]$\mathbf{r_0} = \langle 1, 0, 0 \rangle$[/tex] is the starting point, [tex]$\mathbf{r_1} = \langle 5, 3, 2 \rangle$[/tex] is the ending point, and t is a parameter that goes from 0 to 1.
So we have
[tex]\mathbf{r}(t) &= \langle 1, 0, 0 \rangle + t(\langle 5, 3, 2 \rangle - \langle 1, 0, 0 \rangle) \\\\ &= \langle 1, 0, 0 \rangle + t\langle 4, 3, 2 \rangle \\\\ &= \langle 1 + 4t, 3t, 2t \rangle.[/tex]
From the parametric equation, we have the components:
[tex]x(t) &= 1 + 4t, \\\\y(t) &= 3t, \\\\z(t) &= 2t.[/tex]
The line integral of the force field along the path can be computed by
[tex]$$W = \int_C \mathbf{F} \cdot d\mathbf{r},$$[/tex]
where [tex]$d\mathbf{r}$[/tex] is the differential element along the path C, and the dot product represents the scalar product of the force field and the differential path element.
We can express [tex]$d\mathbf{r}$[/tex] in terms of t as
[tex]$$d\mathbf{r} = \mathbf{r}'(t) dt = \langle \frac{dx}{dt}, \frac{dy}{dt}, \frac{dz}{dt} \rangle dt = \langle 4, 3, 2 \rangle dt.$$[/tex]
Then the work done is
[tex]W &= \int_{t=0}^{t=1} \mathbf{F}(x(t), y(t), z(t)) \cdot \mathbf{r}'(t) dt \\\\ &= \int_{0}^{1} \langle 3t + 2t, 1 + 4t + 2t, 1 + 4t + 3t \rangle \cdot \langle 4, 3, 2 \rangle dt \\\\ &= \int_{0}^{1} [(5t)(4) + (6t + 1)(3) + (7t + 1)(2)] dt \\\\ &= \int_{0}^{1} [20t + 18t + 3 + 14t + 2] dt \\\\ &= \int_{0}^{1} [52t + 5] dt \\\\ &= [26t^2 + 5t]_{0}^{1} \\\\ &= 26(1)^2 + 5(1) - (26(0)^2 + 5(0)) \\\\ &= 26 + 5 \\\\ &= 31.[/tex]
So, the work done by the force field [tex]$\mathbf{F}(x, y, z)$[/tex] on the particle as it moves along the line segment from (1, 0, 0) to (5, 3, 2) is 31 units of work.

Shailen is adding three numbers he gets a sum that is an even number between 10 and 20 show two addition equation shailen could have written
Shailen could have written two possible addition equations like 4 + 3 + 8 = 15 or 5 + 7 + 6 = 18. Both of these sum up to an even number between 10 and 20. Order of numbers doesn't matter in addition due to its commutative property.
Explanation:The problem is asking for two possible addition problems that Shailen could be solving if his sum ends up being an even number between 10 and 20. This involves an understanding of the properties of addition and how different number combinations can result in an even sum.
Here are two possible addition equations that meet the conditions:
4 + 3 + 8 = 15
5 + 7 + 6 = 18
In both cases, the sums fall between 10 and 20 and are even. It's worth noting commutativity of addition, which says the order in which numbers are added doesn't change the sum. Hence, you can rearrange the numbers in the addition (e.g., 3 + 4 + 8 or 8 + 4 + 3) and the sum will still remain the same.

Suppose that work hours in new zombie are 200 in year 1 and productivity is $8 per hour worked. what is new zombie's real gdp? if work hours increase to 210 in year 2 and productivity rises to $10 per hour, what is new zombie's rate of economic growth?
Final answer:
New Zombie's real GDP in year 1 is $1600 and in year 2 is $2100, resulting in a rate of economic growth of 31.25%.
Explanation:
To calculate the real GDP of New Zombie we must multiply the work hours by the productivity (value produced per hour).
For year 1, the real GDP is calculated as follows:
200 hours * $8 per hour = $1600.
For year 2, we calculate the real GDP as:
210 hours * $10 per hour = $2100.
Now, to find the rate of economic growth from year 1 to year 2, we use the formula:
((GDP in year 2 - GDP in year 1) / GDP in year 1) * 100
= (($2100 - $1600) / $1600) * 100
= 31.25%.
Thus, New Zombie's rate of economic growth is 31.25%.

Write the point-slope form of the given line that passes through the points (0, 3) and (4, 0). Identify (x1, y1) as the x-intercept of the line. Include your work in your final answer. Type your answer in the box provided or use the upload option to submit your solution.
The point slope form of the line has the following form:
y – y1 = m (x – x1)
The slope m can be calculated using the formula:
m = (y2 – y1) / (x2 – x1)
m = (3 - 0) / (0 – 4) = - ¾
So the whole equation is:
y – 0 = - ¾ (x – 4)
y = - ¾ (x – 4) or
y = - 0.75 (x – 4)
