Estimates of early Native American hunter-gather societies indicated that a person could

kogti [31]

Other assumptions associated with this question are as follows:

One person can feed on 1 hen/day for a year
1 hen must east 25 grasshoppers /day
the total mass of 1000 grasshoppers is 1kg
600 grasshoppers are needed to feed 1 human per day

Grasshoppers is represented as Gh.

The total amount needed to feed the hen per year is:

25 x 365= 9,125 Gh/Year

If expressed in Kg, then it would be 9,125/1000 which is
= 9.125Kg/annum.

So if the farmer chose to live on grasshoppers rather than on hens, the calculation is given as follows:

(90 kg/1 hour) x (24 hours/1 day) x (1 person/ 600 Gh)

The amount of Grasshoppers required is given as follows;

If the farmer can gather 90 Gh in one hour then,

The total amount of Gh per day is 90 x 24 = 2,160
the total amount of Gh available in a year is 2160 x 365 = 788,400 Gh/Year
If 600 grasshoppers are quired to feed the human per day, then we work backward
The total amount of Gh available in a day is 788,400/365. This is equal to 2160 Gh
The total amount of people this can feed is given as 2,160/600
Which is equal to 3.6 persons.

Since humans or people cannot be divided into fractions like a measure of sugar or a measure of liquid, the answer is best left to the most approximate digit with it 4 Persons.

The regions bounded by the graphs of y=x2 and y=sin2x are shaded in the figure above. What is the sum of the areas of the shaded

Alex Ar [27]

Answer:

The sum of the area of the shaded regions = 0.248685

Explanation:

The sum of the area of the shaded region is given as follows;

The point of intersection of the graphs are;

y = x/2

y = sin²x

∴ At the intersection, x/2 = sin²x

sinx = √(x/2)

Using Microsoft Excel, or Wolfram Alpha, we have that the possible solutions to the above equation are;

x = 0, x ≈ 0.55 or x ≈ 1.85

The area under the line y = x/2, between the points x = 0 and x ≈ 0.55, A₁, is given as follows

1/2 × (0.55)×0.55/2 ≈ 0.075625

The area under the line y = sin²x, between the points x = 0 and x ≈ 0.55, A₂, is given using as follows;

$\int\limits {sin^n(x)} \, dx = -\dfrac{1}{n} sin^{n-1}(x) \cdot cos(x) + \dfrac{n-1}{n} \int\limits {sin^{n-2}(x)} \, dx$

Therefore;

$A_2 = \int\limits^{0.55}_0 {sin^2x} \, dx = \dfrac{1}{2} \left [x -sin(x) \cdot cos(x) \right]_0 ^{0.55}$

∴ A₂ =1/2 × ((0.55 - sin(0.55)×cos(0.55)) - (0 - sin(0)×cos(0)) ≈ 0.0522

The shaded area, $A_{1 shaded}$ = A₁ - A₂ = 0.075625 - 0.0522 ≈ 0.023425

Similarly, we have, between points 0.55 and 1.85

A₃ = 1/2 × (1.85 - 0.55) × 1/2 × (1.85 - 0.55) + (1.85 - 0.55) × 0.55/2 = 0.78

For y = sin²x, we have;

$A_4 = \int\limits^{1.85}_{0.55} {sin^2x} \, dx = \dfrac{1}{2} \left [x -sin(x) \cdot cos(x) \right]_{0.55} ^{1.85} \approx 1.00526$

The shaded area, $A_{2 shaded}$ = A₄ - A₃ = 1.00526 - 0.78 ≈ 0.22526

The sum of the area of the shaded regions, ∑A = $A_{1 shaded}$ + $A_{2 shaded}$

∴ A = 0.023425 + 0.22526 = 0.248685

The sum of the area of the shaded regions, ∑A = 0.248685
