The work done by $\vec F$ is

$\displaystyle\int_C\vec F\cdot\mathrm d\vec r$

where $C$ is the given curve and $\vec r(t)$ is the given parameterization of $C$ . We have

$\mathrm d\vec r=\dfrac{\mathrm d\vec r}{\mathrm dt}\mathrm dt=k(1-2t)\,\vec\imath+\vec\jmath$

Then the work done by $\vec F$ is

$\displaystyle\int_0^1((t-kt(1-t))\,\vec\imath+kt^2(1-t)\,\vec\jmath)\cdot(k(1-2t)\,\vec\imath+\vec\jmath)\,\mathrm dt$

$=\displaystyle\int_0^1((k-k^2)t-(k-3k^2)t^2-(k+2k^2)t^3)\,\mathrm dt=-\frac k{12}$

In order for the work to be 1, we need to have $\boxed{k=-12}$ .

yaroslaw [1]

Answer:A)0.5 We can see in the graph , that it is bell-shaped along x =2. A bell-shaped graph along one value is called symmetric graph and it represents a normal distribution.

Since, the give graph is symmetric around x=2, so the mean of the data is 2.

The point immediate left to the mean represents x-σ

so,

2 - σ = 1.5

So,

σ = 0.5

The sigma represents standard deviation.

Hence, Option A is correct ..

Step-by-step explanation:and what is on d is 2.5

wolverine [178]

About 425 feet, a^2*b^2=c^2, so 90,000+90,000=180,000 and the square root of 180,000 is about 424.

Car Value: In one year a new car decreased in value by 20%. If it sold for $19,400 when it was new, what was it worth after 1 ye

Phantasy [73]

20% of $19,400 is $3,880
($19,400 / 5 = $3,880)
subtract 20% from the original value
($19,400 - $3,880 = $15,520)
it's now worth $15,520
