The capital is £430,600.
Define capital.
The money that a company has on hand to support both its current operations and potential expansion is known as capital. One source of funding for it is the earnings from its operations. When calculating a company's capital worth, all of the company's physical assets and financial assets would be included (minus its liabilities).
The capital account—also referred to as the capital and financial account—records the net flow of investment transactions into an economy and is used in macroeconomics and international finance.
Solution Explained:
Given, Assets = £451,100 and liabilities = £20,500
Capital = Assets - Liabilities
= 451100 - 20500
= £430,600

In an ecology experiment, a number of mosquitoes are placed in a container with water and vegetation. The population of mosquitoes, P, increases and can be modelled by the function:
P9T)=24*4^0.385t, t is greater than or equal to 0
Where t is the time, in days, since the mosquitoes were placed in the container.
(a) find the number of mosquitoes in the container after 5 days
The maximum capacity of the container is 5000 mosquitoes
(b) Find the number of days until the container reaches its maximum capacity.
Using the given exponential function, it is found that:
a) The number of mosquitoes in the container after 5 days is of: 346.
b) The number of days until the container reaches the maximum capacity is of: 10 days.
What is the exponential function?The exponential function that models this problem is presented as follows:
P(t) = 24(4)^(0.385t).
Hence, after five days, the number of mosquitoes is of:
P(5) = 24(4)^(0.385 x 5) = 346 mosquitoes.
The number of days that it takes for the container to reach it's maximum capacity of 5000 is obtained solving the exponential function with logarithms as follows:
[tex]5000 = 24(4)^{0.385t}[/tex]
[tex](4)^{0.385t} = \frac{5000}{24}[/tex]
[tex](4)^{0.385t} = 208.3[/tex]
[tex]\log{(4)^{0.385t}} = \log{208.3}[/tex]
Applying the power property of logarithms, we have that:

Let's play a game where I flip a coin. If the coin lands on Heads you win a $1, if it lands on Tails you lose a $1. I flip a coin 8 times and here is the results Tails Tails Tails Tails Tails Tails Tails Tails So you lost 8 times in a row and thus lose $8.00.
Part1: Would you like to continue this game. Why or why not.
Part 2: Calculate the P-value of getting 8 tails in a row assuming the coin is fair. Is it a big number or small?
Part 3: Based on the P-value you got above what would you conclude about your initial hypothesis that the coin is fair.
Using the z-distribution to test the hypothesis, it is found that:
1. You would not like to continue the game, as in each trial you are losing.
2. The p-value is of 0.0023.
3. The low p-value means that there is enough evidence to conclude that the coin is biased.
What are the hypothesis tested?At the null hypothesis, it is tested if there is not enough evidence that the coin is biased, that is, the proportion of heads is of 0.5, hence:
[tex]H_0: p = 0.5[/tex]
At the alternative hypothesis, it is tested if there is enough evidence that the coin is biased, that is, it has a proportion of heads lower than 0.5, hence:
[tex]H_1: p_1 < 0.5[/tex]
What is the test statistic?The test statistic is given by the equation as follows:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which the variables are listed and explained as follows:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.The values of these parameters are given as follows:
[tex]\overline{p} = \frac{0}{8} = 0, n = 8, p = 0.5[/tex]
Hence the test statistic is:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0 - 0.5}{\sqrt{\frac{0.5(0.5)}{8}}}[/tex]
z = -2.83.
P-value and conclusionUsing a z-distribution calculator, and considering a left-tailed test, as we are testing if the proportion is less than a value, with z = -2.83, the p-value is of 0.0023.
Since this p-value is less than the standard significance level of 0.05, it means that there is enough evidence to conclude that the coin is biased towards tails.

Find the amount of money you will have after 20 years if you invest $25,000 at a rate of 12% if interest is compounded a. Quarterly b. Continuously
The compound interest is quaterly then answer is $266,022.2639 and when it is in continuously then answer is $275,579.4095
Quarterly compounding is what?
Compounding quarterly is the term used to describe the amount of interest that is earned on a quarterly basis on a savings account or investment where the interest is also reinvested. As most banks offer interest income on the deposits, which compounds quarterly, this information is useful in computing the fixed deposit income. It can also be used to figure out any revenue from money market instruments or other financial products that pay quarterly income.
What Does Constant Compounding Mean?
If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach. While this is not attainable in practice, the concept of continually compounded interest is crucial in finance. Given that most interest is compounded on a monthly, quarterly, or semiannual basis, this is an extreme example of compounding.

perpendicular bisector of the line segment whose endpoints are 7,4) and (−9,−4).
Answer:
y=-2x-2
Step-by-step explanation:
If the endpoints of the line segment are (7,4) and (-9,-4), that means that the slope will be:
[tex]\frac{-4-4}{-9-7}[/tex] = [tex]\frac{-8}{-16}[/tex]=[tex]\frac{1}{2}[/tex]. For the perpendicular bisector to be perpendicular to the line, it must have a perpendicular slope, which will be the negative reciprocal of [tex]\frac{1}{2}[/tex], which is -[tex]2[/tex]. The perpendicular bisector must also go through the midpoint of the segment, which is (-1, 0) because -1 is the average of 7 and -9 and 0 is the average of 4 and -4.
Now we find the equation!
y=mx+b. Plug in -[tex]2[/tex] as the "m", or slope:
y=-[tex]2[/tex]x+b
Now, plug in the point (-1, 0):
0=-[tex]2[/tex]*-1+b
0=[tex]2[/tex]+b
b=-[tex]2[/tex]
So, we have m=-[tex]2[/tex] and b=-[tex]2[/tex] and we can form our equation!
y=-[tex]2[/tex]x-[tex]2[/tex]

Differentiate the function with respect to x.
The differentiation of the given function is 12[tex]x^3[/tex](5[tex]x^2[/tex] +2).
In the given question we have to differentiate the given function with respect to x.
The given function is f(x) = [tex]2x^4(5x^2+3)[/tex]
Before differentiating the function we first simplify the given expression.
To simplify the expression we multiply the 2x^4 to each term under the bracket.
Now the function;
f(x) = [tex]2x^4\cdot5x^2+3\cdot2x^4[/tex]
As we know that if the base is same en power get added.
f(x) = [tex]10x^{4+2}+6x^4[/tex]
f(x) = [tex]10x^{6}+6x^4[/tex]
Now differentiating the function with respect to x.
f'(x) = d/dx([tex]10x^{6}+6x^4[/tex])
f'(x) = 10d/dx([tex]x^6[/tex]) + 6d/dx([tex]x^4[/tex])
As we know that d/dx of x^n =nx^(n-1). So
f'(x) = 10∙6 [tex]x^5[/tex] + 6∙4 [tex]x^3[/tex]
f'(x) = 60[tex]x^5[/tex]+24[tex]x^3[/tex]
Now taking 12x^3 common

Write one quadratic equation that forms a graph through the points (−4,2) and (2,2) and has a
maximum value at the vertex.
Explain please
Quadratic equation that passes through the points (-4,2) and (2,2) and a form a graph of horizontal line y =2.
Given,
Quadratic equation passes through the points (-4,2) and (2,2)
(x₁, y₁) =(-4,2)
(x₂ ,y₂) = (2,2)
Here,
(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)
⇒(y - 2) / (x + 4) = (2 - 2) / (2 + 4)
⇒ (y-2) / (x+4) =0
⇒y -2 =0
⇒y = 2
Quadratic equation formed from the given points (-4,2) and (2,2) is y =2.
Which represents the horizontal line and does not have any vertex.
Therefore, quadratic equation that passes through the points (-4,2) and (2,2) and a form a graph of horizontal line y =2.
