Katy invests £200 000 in a savings account for 4 years. The account pays compound interest
at a rate of 1.5 % per annum.
Calculate the total amount of interest Katy will get at the end of 4 years

Answers

Answer:

212272.71

Step-by-step explanation:

we have the following equation (for interesting that compound yearly)

PV(1+i)^n

200000(1+.015)^4

212272.71

The total amount of interest Katy will get at the end of 4 years is £12,272.71

Compound interestCompound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interestCompound interest refers to the phenomenon whereby the interest associated with a bank account, loan, or investment increases exponentially—rather than linearly—over time.Compound interest (or compounding interest) is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods

How to solve this problem?

The steps are as follow:

Given:

p = £200 000

r = 1.5%

n = 4 years

Formula to find Amount (A) after 4 years will as follow:

A = p(1+r/100)ⁿ

A = 200000(1+1.5/100)⁴

A = 212,272.71 £

The compound interest is given by:

C.I. = A - p

C.I. = 212,272.71 - 200,000

C.I. = £12,272.71

So the  total amount of interest Katy will get at the end of 4 years is £12,272.71

Answer:

So that means that x= 180-75 or x=105 degrees

State sales tax S is directly proportional to retail price p . An item that sells for 172 dollars has a sales tax of 12.32 dollars. Find a mathematical model that gives the amount of sales tax S in terms of the retail price p . Function: S ( p )

Answers

Answer:

[tex]s(p) =\frac{77p}{1075}[/tex]

Step-by-step explanation:

Given

s = sales tax

p = retail price

The variation is represented as:

[tex]s\ \alpha\ p[/tex]

s = 12.32 when p = 172.

Required: Determine function s(p)

[tex]s\ \alpha\ p[/tex]

Convert to equation

[tex]s = kp[/tex]

Where k is the constant of variation.

Make k the subject

[tex]k =\frac{s}{p}[/tex]

Substitute values for s and p

[tex]k =\frac{12.32}{172}[/tex]

Multiply by 100/200

[tex]k = \frac{1232}{17200}[/tex]

Simplify:

[tex]k =\frac{77}{1075}[/tex]

To get the function, we substitute 77/1075 for k in:[tex]s = kp[/tex]

[tex]s =\frac{77}{1075}p[/tex]

[tex]s =\frac{77p}{1075}[/tex]

Express as a function

[tex]s(p) =\frac{77p}{1075}[/tex]

If a number is multiplied by 7, the result is the same as when 25 is added
to twice the number. Find the number.

Answers

Answer:

Step-by-step explanation:

"a number is multiplied by 7" can be represented by 7x

"25 is added to twice the number" can be represented by 2x+25

7x = 2x+25

5x = 25

x = 5

The number is 5 if  a number is multiplied by 7, the result is the same as when 25 is added to twice the number.

What is linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the number is x:

From the problem, we can model a linear equation in one variable.

7x = 2x + 25

5x = 25

x = 5

Thus, the number is 5 if  a number is multiplied by 7, the result is the same as when 25 is added to twice the number.

(5,3) will make a rhombus.

What is Rhombus?

A Quadrilateral with all sides equal but with nonequal diagonals is know as Rhombus.

How to solve?

Let D have coordinate (x,y)

The length of all the sides of the rhombus is equal.

length of AB = [tex]\sqrt{({2-3})^2 + ({2-4})^2} = \sqrt{1+4} = \sqrt{5}[/tex]

Similarly BD = [tex]\sqrt{({3-x})^2 + ({4-y})^2} = \sqrt{25+{x}^2+{y}^2-6x-8y}[/tex] -------------(1)

CD = [tex]\sqrt{({4-x})^2 + ({1-y})^2} = \sqrt{17+{x}^2+{y}^2-8x-2y}[/tex] -------------(2)

We know BD = CD gives,

[tex]\sqrt{17+{x}^2+{y}^2-8x-2y} = \sqrt{25+{x}^2+{y}^2-6x-8y}[/tex]

By squaring both sides and solving we get,

3y - x = 4 ----------------------(3)

Since BCD is a right-angled triangle,

[tex]{BC}^2 = {BD}^2 + {CD}^2[/tex]  

BC = [tex]\sqrt{10}[/tex]

10 = 5 + [tex]\sqrt{17+{x}^2+{y}^2-8x-2y}[/tex]

8  = [tex]{x}^2+{y}^2-8x-2y[/tex] -------------------(4)

solving equation (3) and (4) we get x = 5 and y = 3
