Answer:

x = -1

Explanation:

5x + 2 = 3x

5x - 3x = -2

2x = -2

x = $\dfrac{-2}{2}$

x = -1

Hope this helps! ☺

Find the value of the line integral. F · dr C (Hint: If F is conservative, the integration may be easier on an alternative path.

Harman [31]

Answer: a) Fdr = 0 b) Fdr = 0

Step-by-step explanation:

According to the integral Fdr

a) If r=t²i + t²j

If the field F(x, y, z) = y sin(z)i + x sin(z)j + xy cos(x)k

Integral Fdr = y sin(z)i + x sin(z)j + xy cos(x)k d(t²i + t²j)

Multiplying component wise.

Fdr = y sin(z)i(dt²i) + x sin(z)j(dt²j) + xy cos(x)k d(0k)

Remember that dot product of different components gives 'zero' i.e i.j = 0 etc.

Fdr = ysin(z)dt² + xsin(z)dt² + 0...(1)

Generally for 2dimensional object r=xi+yj

Comparing this to r = t²i+t²j

x=t² and y = t² z = 0...(2)

Substituting 2 into 1

Fdr = t²sin0dt² + t²sin0dt²

Integrating resulting Fdr with respect to t² within the limit 0 ≤ t ≤ 2, we have

Fdr = 0

b) since there is no z-component in the second part as well, integral of Fdr within the limit 0 ≤ t ≤ 1 will also be 0.

The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 13.1 years; the standard devia

Ilia_Sergeevich [38]

Answer:

The probability between 16.1 and 17.6 years = 0.0214 years

The Estimate probability between 16.1 and 17.6 years = 2.14 years

Step-by-step explanation:

Step(i):-

Given the average of Population 13.1 years

The standard deviation of the Population = 1.5 years

Let 'x' be the random variable in Normal distribution

Given x = 16.1

$Z _{1} = \frac{x- mean}{S.D}$

$=\frac{16.1-13.1}{1.5}$

= 2

Z₁ = 2

Step(ii):-

Given x = 17.6

$Z_{2} = \frac{17.6- 13.1}{1.5}$

Z ₂= 3

Z₁ = 2 and Z ₂= 3 are both positive

The Estimate probability between 16.1 and 17.6 years

P( 16.1<x<17.6) = P( 2 < Z < 3)

= A(3) - A(2)

= 0.49865 - 0.4772 (from normal table)

= 0.0214

The probability between 16.1 and 17.6 years = 0.0214 years

= 0.0214 ×100

= 2.14 years

Final answer:-

The Estimate probability between 16.1 and 17.6 years = 2.14 years
