Prove that the product of any two consecutive integers is even

Answers

Answer 1

Answer:

Credit: Luqman Khan

Explanation:

n(n+1)

n^2+n

check first case n=1

1+1=2 2(1)

it works for first case

assume true for n=k

k^2+k=2A

check n=k+1

(k+1)^2+(k+1)

k^2+2k+1+k+1

k^2+3k+2

k^2+k+2k+2

2A+2k+2

2(A+K+2)

It works for first case. If it works for n=k, then it also works for n=k+1

Then it is true for all 2 consecutive numbers, by mathematical induction

What is frost?

Water that has changed from a liquid or gas to a solid is called frost. Typically, frost forms on exterior objects like cars, windows, and plants when there is moist air present. Areas with a lot of fog frequently have heavy frosts. Frost develops when an outside surface cools below the dew point.

Temperatures higher than 32 °F can cause frost to occur. A1: The ice coating that forms on surfaces at or below 32 degrees Fahrenheit is what is referred to as frost. On occasion, frost can develop over night on your grass even though the temperature has not fallen below freezing.

When water vapour from an environment above freezing comes into touch with a solid surface, a thin film of ice called "frost" is created.

Thus, Frost faced many challenges throughout his life.

At what temperature teq do the forward and reverse corrosion reactions occur in equilibrium?

Answers

Standard Gibb's free energy at 298K and 5975K is 3.16×10⁶J and -3.83×10⁵J respectively, and temperature at equilibrium state is 5362.3 K.

What is the standard Gibb's free energy?

The complete question is in the brainly link at the end. We can say that;

Standard Gibb's free energy of any reaction is gotten from the formula;

∆G° = ∆H° - T∆S°

where;

∆G° is change in free energy

∆H° is change in enthalpy = 3352 kJ = 3352 × 10³J

∆S° is change in entropy = 625.1 J/K

T is absolute temperature = 298 K

Plugging in the relevant values into the gibbs energy equation gives;

∆G° = (3352 × 10³) - (298 × 625.1)

∆G° = 3.16 × 10⁶J

Gibb's free energy at temperature of 5,975 K is;

∆G° = (3,352 × 10³) - (5,975 × 625.1)

∆G° = -3.83 × 10⁵J

At the equilibrium state, the value of Gibb's free energy is zero. Thus we can calculate the temperature as;

0 = (3352 × 10³)J - (T × 625.1 J/K)

Solving for T gives;

T = 5362.3 K

What would the population size of sika deer be one year after the carrying capacity increased to 70,000 as a result of deforestation? assume rmax does not change.

Answers

The population size of Sika deer one year after the carrying capacity increased to 70000 as a result of deforestation is; 63667 deer

How to Calculate Growth Rate?

We are given the following about the Sika deer population;

Initial Population in 2005 = 26000

Stabilized Population between 2012 and 2014 = 58000

r_max for population = 0.57

Now, we want to find the population size of Sika deer one year after the carrying capacity increased to 70000 as a result of deforestation

Thus;

carrying capacity; k = 70000

population size; N = 58000

max growth rate; r_max = 0.57

Formula for the growth is;

dN/dt = (r_max × N)[(K - N)/K]

Plugging in the relevant values gives;

dN/dt = 0.57 × 58000[12000/70000]

dN/dt = 5667

Thus;

Increase in population = 5667 + 58000

⇒ 63667
