So, after 4 years, a £230 investment will be worth roughly £283.52 at a 5% yearly income rate compounded annually.
An illustration of compound interest is given?Let's assume you spend $1,000 (your capital) and it makes 5% once a year in interest or profits (the compounding frequency). You would've had $1,050 at the end of the first year, which is your initial capital plus an additional $5, or $50. You would also have $1,102.50 in the following year.
We can use the compound interest algorithm to find a solution to this issue:
[tex]A=P\left(1+\frac{r}{n}\right)^{n t}[/tex]
where A is the final amount, P is the initial investment, r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time in years.
In this case, we have:
P = £230 (the initial investment)
r = 5% = 0.05 (the annual interest rate as a decimal)
n = 1 (since the interest is increased yearly) (since the interest is compounded annually)
Given that we're searching for a number after four years, t = 4.
With these numbers entered into the algorithm, we obtain:
A = 230(1 + 0.05/1)⁴
A = 230(1.05)⁴
A = £283.52

2. Prove the trig identity.
sin x ( 1 + cot^2x)
I have a calculus exam tomorrow and have no idea how to solve this equation, please provide a detailed explanation. I'm slow.
Answer:
We'll start with the left-hand side (LHS) of the identity, which is:
sin x (1 + cot^2 x)
We can rewrite cot^2 x as (cos x / sin x)^2, since cotangent is the reciprocal of tangent. Substituting this into the LHS, we get:
sin x (1 + (cos x / sin x)^2)
Now we can simplify the expression in the parentheses by using the identity:
tan^2 x + 1 = sec^2 x
Rearranging this identity, we get:
tan^2 x = sec^2 x - 1
Substituting this into our expression, we get:
sin x (1 + (cos x / sin x)^2) = sin x (1 + (cos^2 x / sin^2 x))
= sin x (sin^2 x / sin^2 x + cos^2 x / sin^2 x)
= sin x ((sin^2 x + cos^2 x) / sin^2 x)
= sin x (1 / sin^2 x)
= sin x / sin^2 x
= 1 / sin x
Now we'll simplify the right-hand side (RHS) of the identity, which is:
csc x
We know that csc x is the reciprocal of sin x, so we can rewrite the RHS as:
1 / sin x
This is the same as the expression we obtained for the LHS, so we have shown that:
sin x (1 + cot^2 x) = csc x
And this proves the identity!
Remember, when you're proving trigonometric identities, it's important to be familiar with the fundamental trigonometric identities and the basic algebraic rules of manipulating equations

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 × 1012 miles. Suppose a star is 9.8 × 101 light-years from Earth. In scientific notation, approximately how many miles is it? (1 point) 5.88 × 1013 miles 5.76 × 1014 miles 5.88 × 1012 miles 9.8 × 1012 miles
The correct answer is 5.88 × 1013 miles. This is because a light-year is the distance that light can travel in one year, or approximately 5.88 × 1012 miles.
What is a light year?A light year is a unit of distance used to measure astronomical distances. It is the distance that light travels in a vacuum in one year, which is equal to 9.46 trillion kilometres. This means that light travelling at a speed of 300,000 kilometres per second would take one year to travel nine trillion kilometres. T
To find the distance of a star from Earth, one must multiply the number of light-years by 5.88 × 1012. In this case, the star is 9.8 × 101 light-years away, meaning that it is 9.8 × 101 times 5.88 × 1012 miles, or 5.88 × 1013 miles, away from Earth.
Light-years are a unit of distance used by astronomers to measure the great distances between stars and galaxies. Light travels at a speed of approximately 186,000 miles per second, and one light-year is the distance that light can travel in one year. For example, a star that is 9.8 × 101 light-years away from Earth is approximately 5.88 × 1013 miles away from Earth. To convert the number of light-years to the number of miles, one must multiply the number of light-years by 5.88 × 1012.

Triangle with the coordinates A (-5,-1), B (-4,4), C (-1,-1)
Given a parallelogram ABCD, the measures of angle B = 3x + 36 and angle D = 6x - 6 : find m angle A
Answer: In a parallelogram, opposite angles are congruent. So we know that angle A is congruent to angle C. Let's call the measure of angle A "y".
Therefore, we have:
angle A = y
angle B = 3x + 36
angle C = y (because opposite angles in a parallelogram are congruent)
angle D = 6x - 6
The sum of the measures of the angles in a parallelogram is 360 degrees. So we can write an equation:
angle A + angle B + angle C + angle D = 360
Substituting in the values we know:
y + (3x + 36) + y + (6x - 6) = 360
Simplifying:
2y + 9x + 30 = 360
2y + 9x = 330
Now we have an equation with two variables. But we also know that angle A and angle C are congruent, so y = angle A = angle C. Substituting this into the equation above:
2(angle A) + 9x = 330
2(angle A) = 330 - 9x
angle A = (330 - 9x)/2
Therefore, the measure of angle A is (330 - 9x)/2.

Write a function to represent the number of frogs, f, in the lake after m months.
f(m) =
The required function is f(m) = -53.33m + 360, where f(m) represents the number of frogs in the lake after m months.
What is function ?
In mathematics, a function is a rule that assigns a unique output or "dependent variable" to each input or "independent variable" in a set. It is a relation between a set of inputs and a set of possible outputs, with the property that each input is related to exactly one output.
Based on the given graph, it appears that the number of frogs in the lake is decreasing linearly over time. We can use the slope-intercept form of a linear equation to represent this relationship:
y = mx + b
where y is the number of frogs, x is the time in months, m is the slope (or rate of decrease) of the line, and b is the initial number of frogs at time zero.
To find the slope of the line, we can use the two points (0, 360) and (3, 200) from the graph:
m = (change in y) / (change in x) = (200 - 360) / (3 - 0) = -53.33
So the slope of the line is -53.33, which means that the number of frogs is decreasing by an average of 53.33 per month.
To find the initial number of frogs, we can use the y-intercept of the line, which appears to be around 360 on the graph. So we have:
b = 360
Putting it all together, the function that represents the number of frogs in the lake after m months is:
f(m) = -53.33m + 360
Therefore, the required function is f(m) = -53.33m + 360, where f(m) represents the number of frogs in the lake after m months.

The present value of the security is $2142.86, rounded to the nearest cent.
What is value?Value is a subjective concept that is based on personal beliefs, experiences, and backgrounds. It is the appreciation of something, whether tangible or intangible, that is based on a person's perception of its worth. Value is often used to describe the worth or importance of something or someone, and can be expressed in monetary terms or in terms of the usefulness of something. Ultimately, value is the measure of how much something is worth to an individual.
The present value of this security is $2142.86. This is determined by using the formula:
Present Value = Dividend / (1 + R)t
Where Dividend is the annual dividend of $150, R is the rate of return which is 7%, and T is the time in years which is 1.
Therefore, the present value of the security is:
150 / (1 + 0.07)¹ = $2142.86
Thus, the present value of the security is $2142.86, rounded to the nearest cent.
