Sketch the solid whose volume is given by the iterated integral.
A sketch of the solid whose volume is given by the iterated integral is shown in the image attached below.
How to calculate an integral?In this exercise, you're required to sketch the solid whose volume is given by the iterated integral below. Thus, we would first of all evaluate the integral so as to get a unit value.
Given the following integral:
∫¹₀∫₀¹(4 - x - 2y)dxdy
Integrating x with respect to y, we have:
∫¹₀∫₀¹(4 - x - 2y)dxdy = ∫¹₀[(4 - (1/2)- 2y)]dy
∫¹₀∫₀¹(4 - x - 2y)dxdy = 4y - (y/2) - (2y²/2)|¹₀
Evaluating the integral, we have:
∫¹₀∫₀¹(4 - x - 2y)dxdy = 4(1) - (1/2) - (2(1)²/2)
∫¹₀∫₀¹(4 - x - 2y)dxdy = 4 - 1/2 - 1
∫¹₀∫₀¹(4 - x - 2y)dxdy = 5/2
In conclusion, a sketch of the solid whose volume is given by the iterated integral is shown in the image attached below.

Calculate the energy stored in a spring when it is compressed 5mm by a 60n force
If a 60-N force is compressing the spring a distance of 5 mm = 0.005 m, then by Hooke's law, the spring has constant k such that
60 N = k (0.005 m) ⇒ k = 12,000 N/m
Then the spring is storing
1/2 (12,000 N/m) (0.005 m)² = 0.15 J

If c=3,6 and d=4,8. the coordinate of the point of cd is
The coordinate of CD is the position of CD
The coordinate of the midpoint of CD is (3.5, 7)
How to determine the coordinate of CD?The coordinates are given as:
C = (3,6)
D = (4,8)
Next, we calculate the midpoint of CD using the following midpoint formula
CD = 0.5 * (x₁ + x₂, y₁ + y₂)
So, we have:
CD = 0.5 * (3 + 4, 6 + 8)
Evaluate the sum
CD = 0.5 * (7, 14)
Evaluate the product
CD = (3.5, 7)
Hence, the coordinate of the midpoint of CD is (3.5, 7)

What is genetic drift?Genetic drift is a mechanism of evolution in which allele frequencies of population change with generations due to chance (sampling error). Genetic drift occurs in all the populations of non-infinite size, but its effects are the strongest in small populations.
Genetic drift occurs in small populations, where infrequently-occurring alleles faces greater chance of being lost. Once it begins, genetic drift continues until the involved allele is either lost by population or is the only allele present at particular gene locus within the population.
Genetic drift is primarily associated with small breeding populations and mutations are regarded as strong evolutionary mechanism for changing allelic frequencies.
