A new disease has recently been discovered in a village, and you have been brought in to investigate. The disease appears to pass from one person to another when they shake hands, and it can be cured with antibiotics. What can you say about this disease?.
Answer:
The disease is a deadly disease
Explanation:
it need to be taken care of immediate effect.
The disease appears to pass from one person to another when they shake hands, and it can be cured with antibiotics. The pathogen is directly transmitted, and replicates by using the replication machinery of the host cells.
What are pathogen ?
pathogens are the biological organism which can cause a disease in one organism to another by infecting them and causes infectious diseases. ‘Pathogen’ is a disease-causing organisms are bacteria, viruses, fungi, protozoans and worms.
There are different types of pathogens where Class 1 pathogen are the agents in which the organism is not associated with infectious disease.
on the other hand Class 2 are the pathogen are the organism which cause disease in humans but it is not serious and can be preventive by using different methods, treatments are available.
Class 3 pathogens include the organism which can cause serious diseases in humans but there are some necessary prophylaxis and treatment are available.
Class 4 pathogens serious causative agent for human disease and spread in the human population with no adequate prophylaxis .

Evaluate the line integral by the two following methods. Xy dx + x2y3 dy c is counterclockwise around the triangle with vertices (0, 0), (1, 0), and (1, 4).
Not sure what "two methods" you refer to, so I'll assume you're supposed to compute the line integral directly as well as with Green's theorem.
Direct computation:
It looks like the line integral is
[tex]\displaystyle \int_C xy \, dx + x^2y^3 \, dy[/tex]
where C is the union of three line segment. We'll partition C and parameterize each component by
• C₁, the line segment from (0, 0) to (1, 0) : x(t) = t and y(t) = 0;
• C₂, from (1, 0) to (1, 4) : x(t) = 1 and y(t) = 4t;
• C₃, from (1, 4) to (0, 0) : x(t) = 1 - t and y(t) = 4 - 4t;
each with 0 ≤ t ≤ 1.
Compute the integrals over each component:
• Along C₁, we have y = 0, so this integral contributes nothing.
• Along C₂,
[tex]\displaystyle \int_0^1 4t \cdot 0 \, dt + (4t)^3 \cdot 4 \, dt = 256 \int_0^1 t^3 \, dt = 64[/tex]
• Along C₃,
[tex]\displaystyle \int_0^1 (1-t)(4-4t) \cdot (-dt) + (1-t)^2(4-4t)^3 \cdot (-4\, dt) \\\\ = \int_0^1 \left(-260 + 1288 t - 2564 t^2 + 2560 t^3 - 1280 t^4 + 256 t^5 \right) \, dt = -44[/tex]
So, the total line integral is
[tex]\displaystyle \int_C xy \, dx + x^2y^3 \, dy = 0 + 64 - 44 = \boxed{20}[/tex]
Using Green's theorem:
The interior of C is the triangular region
[tex]D = \{(x, y) : 0 \le x \le 1 \text{ and } 0 \le y \le 4x\}[/tex]
and the integrand has no singularities either on C or within D. So by Green's theorem,
[tex]\displaystyle \int_C xy \, dx + x^2y^3 \, dy = \iint_D \frac{\partial(x^2y^3)}{\partial x} - \frac{\partial(xy)}{\partial y} \, dx \, dy = \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx[/tex]
The remaining integral is trivial.
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \int_0^1 x \int_0^{4x} (2y^3 - 1) \, dy \, dx[/tex]
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \int_0^1 x \left(\frac12 (4x)^4 - 4x\right) \, dx[/tex]
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \int_0^1 \left(128x^5 - 4x^2\right) \, dx[/tex]
[tex]\displaystyle \int_0^1 \int_0^{4x} (2xy^3 - x) \, dy \, dx = \frac{64}3 - \frac43 = \boxed{20}[/tex]
For a computer workplace, ergonomics experts recommend an area smaller than two feet by four feet.
The concept of computer workplace ergonomics is aimed at defining a comfortable workstation setup to aid the health of computer users.
The recommended size of the workspace is to ensure that the appropriate body parts can function without stress or strain while using the workstation. The position of the seat shouldn't be too far off or near in other to protect vision and avoid stress on the legs, elbows and avoid numbness.Hence, the size of a workstation should be kept as small as possible in other to aid interaction between users and the computer.

What mass of glucose (C6H12O6) should be dissolved in 12. 0 kg of water to obtain a solution with a freezing point of -5. 8 ∘C?.
Answer:
6.7 kg
Explanation:
(0) - (-5.8)= 5.8ºC
5.8 / 1.86 = 3.12 m C6 H12 O6
The molar mass of C6 H12 O6 is: 180.156 g/mol
3.12 * 12 kg * 180.156 g/mol = 6,745.041 g = 6.7 kg.
The mass of glucose solute dissolved in the solution is 6.739 Kg.
Recall that;
ΔT = K m i
ΔT = Freezing point depression
K =Freezing point depression constant = 1.86°C/mol
m = molality of the solution
i = Van't Hoff factor = 1 (molecular solution)
We have to find the freezing point depression from;
Freezing point depression = Freezing point of pure solvent - Freezing point of solution
Freezing point of pure water = 0°C
Freezing point of solution = -5. 8 ∘C
Freezing point depression = 0°C - (-5. 8 ∘C) = 5. 8 ∘C
Now;
m = ΔT/K i
m = 5. 8 ∘C/ 1.86°C/mol × 1
m = 3.12 m
But molality = number of moles of solute/mass of solvent in Kg
Molar mass of solute = 180 g/mol
Let the mass of solute be m
3.12 = m/180/12
3.12 = m/180 × 12
m = 3.12 × 180 × 12
m = 6739 g or 6.739 Kg

Martin decided to buy 3 bags of grapes weighing 4 1 5 pounds each. How much did all 3 bags of grapes weigh? 1 and one-fifth 7 and one-fifth 12 and one-fifth 12 and three-fifths.
Answer:
12 3/5
Explanation:
12 3/5 pounds
Step-by-step explanation:
Martin decided to buy 3 bags of grapes.
The weight of each bag = 4\frac{1}{5}451 pounds
We have to calculate the weight of all 3 bags of grapes.
So we multiply 4\frac{1}{5}451 to 3
= \frac{21}{5}521 × \frac{3}{1}13
= \frac{63}{5}563
= 12\frac{3}{5}1253 pounds
The weight of all 3 bags of grapes were 12\frac{3}{5}1253 pounds.
