Brian invests £8200 into his bank account.
He receives 6.0% per year simple interest.
How much will Brian have after 2 years?
Give your answer to the nearest penny where appropriate.
Answers
Answer:
£9184
Step-by-step explanation:
Interest = PRT/100
P = Price
R = Rate
T = time
First Let's find the interest for 2 years
[tex]interest = \frac{8200 \times 6 \times 2}{100} \\ = 984[/tex]
So, the interest is £984
Now let's find the full amount he received after two years ,
[tex]8200 + 984 = 9184[/tex]
Total Amount = £9184
Hope this helps you

You are applying for jobs at two companies. Company A offers starting salaries with μ = $41,000 and σ = $1,000. Company B offers starting salaries with μ = $41,000 and σ = $5,000. From which company are you more likely to get an offer of $43,000 or more? Justify your answer
Answers
Company B is likely to get an offer of $43,000 or more.
Here we will use a normal distribution and calculation to calculate z-score for each company.
z-score for the company A = (43,000 - 41,000) / 1000
= 2000/1000= 2
z-score for the company B = (43,000 - 41,000) / 5000
= 2000/5000
0.4
Now we will consult z-tables for Probability(P)
P(x > 43000 ) for A = 1- P( x < 43000) = 1 - 0.9772 = 0.0228
P(x > 43000) for B = 1 - P(x< 43000) = 1 - 0.7734 = 0.2266
Therefore the probability is greater with company B that will likely get an offer of $43,000 or more.

You are an electrician for the city where you live. You get a
call about a parking lot at baseball field where the lamp posts
keep shutting off, due to the circuit breaker. A circuit
breaker is a switch that automatically stops the flow of
electricity due to a current being too strong or some other
dangerous situation. You've been called in to figure out why
the circuit is breaking

One of the most common formulas dealing with electricity is
called Watt's Law. This algebraic equation states that "pi
(power measured in watts) is equal to "V" (the voltage
measured in volts ) times "T" (the current measured in amps).
P= VI
Here is what you know about the baseball field parking lot situation.
There are 9 lamp posts connected to this circuit.
Each lamp post has a 400 watt lamp installed.
The circuit is 120-volt and 20-amp.
Here is what you don't know, but can figure out:
How much power can
the circuit handle?
(Use Wate's Law)
How many watts does 9
lampposts require?
How many lampposts
could this circuit actually
handle?
Answers
Answer: 2400
Step-by-step explanation:
120*20
The power consumed by circuit is 2400 watt
What is Power?The quantity of energy transferred or transformed per unit of time is known as power. The watt, or one joule per second, is the unit of power in the International System of Units.
Electrical power is the product of voltage and current. P = V X I .
Given:
Potential Difference= 120 vatt
Current = 20 Ampere
Now, using
Power = V x I
Power= 120 x 20
Power = 2400 Watt
Hence, the power consumed by circuit is 2400 watt

−7(x−3)−27=−6
Answers
To evaluate, we will use PEMDAS, so then parenthesis will come first:
-7x+21-27=-6
We have no exponents, multiplication, or division, so addition/subtraction of like terms will be our next step.
-7x-6=-6
Now we can solve for x. To do this, we will first isolate the -7x by adding 6 to both sides.
-7x=0
We will then isolate x by dividing both sides by -7, which will give us:
x=0
Answer:
x = 0
Step-by-step explanation:
−7(x−3)−27=−6
(-7*x -7*-3) - 27 = -6
-7x + 21 - 27 = -6
-7x - 6 = -6
-7x = 6 - 6
-7x = 0
x = 0
check:
-7(0-3) - 27 = -6
-7*-3 -27 = -6
21 - 27 = -6
Find the value of x.

Answers
Geometric sequence is characterized by a common ratio
(1) Sum of first 5 terms
The first term of the sequence is:
[tex]\mathbf{a = 3}[/tex]
The common ratio (r) is:
[tex]\mathbf{r = 6 \div 3 = 2}[/tex]
The sum of n terms is calculated using:
[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]
So, we have:
[tex]\mathbf{S_5 = \frac{3 \times (2^5 - 1)}{2 - 1}}[/tex]
[tex]\mathbf{S_5 = \frac{93}{1}}[/tex]
[tex]\mathbf{S_5 = 93}[/tex]
Hence, the sum of the first five terms is 93
(2) Sum of first 5 terms
The first term of the sequence is:
[tex]\mathbf{a = 14}[/tex]
The common ratio (r) is:
[tex]\mathbf{r = 3}[/tex]
The sum of n terms is calculated using:
[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]
So, we have:
[tex]\mathbf{S_5 = \frac{14 \times (3^5 - 1)}{3 - 1}}[/tex]
[tex]\mathbf{S_5 = \frac{3388}{2}}[/tex]
[tex]\mathbf{S_5 = 1694}[/tex]
Hence, the sum of the first five terms is 1694
(3) Sum of first n terms
The first term of the sequence is:
[tex]\mathbf{a = 318}[/tex]
The common ratio (r) is:
[tex]\mathbf{r = \frac12}[/tex]
The sum of n terms is calculated using:
[tex]\mathbf{S_n = \frac{a(1 - r^n)}{1 - r}}[/tex]
So, we have:
[tex]\mathbf{S_n = \frac{318 \times (1 - \frac 12^n)}{1 - \frac 12}}[/tex]
[tex]\mathbf{S_n = \frac{318 \times (1 - \frac 12^n)}{\frac 12}}[/tex]
[tex]\mathbf{S_n = 636 (1 - \frac 12^n)}[/tex]
Hence, the sum of the first n terms is [tex]\mathbf{ 636 (1 - \frac 12^n)}[/tex]
(4) The first term
The sum of the first 7th term of the sequence is:
[tex]\mathbf{S_7 = 547}[/tex]
The common ratio (r) is:
[tex]\mathbf{r = -3}[/tex]
The sum of n terms is calculated using:
[tex]\mathbf{S_n = \frac{a(1 - r^n)}{1 - r}}[/tex]
So, we have:
[tex]\mathbf{547 = \frac{a(1 - (-3)^7)}{1 - -3}}[/tex]
[tex]\mathbf{547 = \frac{a(2188)}{4}}[/tex]
Multiply both sides by 4
[tex]\mathbf{2188= a(2188)}[/tex]
Divide both sides by 2188
[tex]\mathbf{1= a}[/tex]
Rewrite as:
[tex]\mathbf{a = 1}[/tex]
Hence, the first term is 1
(5) Find the 7th term
The first term of the sequence is:
[tex]\mathbf{a=2}[/tex]
The common ratio (r) is:
[tex]\mathbf{r=3}[/tex]
The nth term of a geometric sequence is:
[tex]\mathbf{T_n = ar^{n -1}}[/tex]
So, we have:
[tex]\mathbf{T_7 = 2 \times 3^{7 -1}}[/tex]
[tex]\mathbf{T_7 = 1458}[/tex]
Hence, the seventh term is 1458
(6) Sum of geometric sequence
The first term of the sequence is:
[tex]\mathbf{a=2}[/tex]
The common ratio of the sequence is:
[tex]\mathbf{r = 6 \div 2 = 3}[/tex]
The number of terms is:
[tex]\mathbf{n = 5}[/tex]
The sum of n terms is calculated using:
[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]
So, we have:
[tex]\mathbf{S_5 = \frac{2 \times (3^5 - 1)}{3 - 1}}[/tex]
[tex]\mathbf{S_5 = \frac{484}{2}}[/tex]
[tex]\mathbf{S_5 = 242}[/tex]
Hence, the sum of the first five terms is 242
(7) The first term
The sum of the first five terms is given as:
[tex]\mathbf{S_5 = 341}[/tex]
The common ratio is:
[tex]\mathbf{r = 4}[/tex]
The sum of n terms is calculated using:
[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]
So, we have:
[tex]\mathbf{341 = \frac{a \times (4^5 - 1)}{4 - 1}}[/tex]
[tex]\mathbf{341 = \frac{a \times 1023}{3}}[/tex]
Solve for a
[tex]\mathbf{a = \frac{3 \times 341}{1023}}[/tex]
[tex]\mathbf{a = 1}[/tex]
Hence, the first terms is 1
(8) Sum to infinite
The first term of the sequence is:
[tex]\mathbf{a = 192}[/tex]
The common ratio (r) is:
[tex]\mathbf{r = \frac 14}[/tex]
The sum to infinite is:
[tex]\mathbf{S_{\infty} = \frac{a}{1 - r}}[/tex]
So, we have:
[tex]\mathbf{S_{\infty} = \frac{192}{1 - 1/4}}[/tex]
[tex]\mathbf{S_{\infty} = \frac{192}{3/4}}[/tex]
[tex]\mathbf{S_{\infty} = 256}[/tex]
Hence, the sum to infinite is 256
