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?
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

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.
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

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
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.

Therefore, the answer is (-4, 0).
AB is parallel to CD. CD is rotated 180° Which statement describes the relationship between ('D' and the transformed AB? How can
you prove it?
Answer:
Answer :- Statement (B) ,C'D' ll AB
Given AB is parallel to CD. CD rotated.
Consider a transversal line l intersecting AB and CD at angle x.
therefore By slope formula,
slope of AB and CD = m =tanx
Now after rotation of 180 CD become C'D'
therefore, slope of C'D' = =tanx=m
Hence C'D' ll AB.

Tim’s savings account pays a simple annual interest rate of 3.5%. Suppose he deposits $5,500 in the account and makes no additional deposits or withdrawals for 5 years. What will the total value of the account be after 5 years?
$6462.5
Simple Interest = (Principal × Rate × Time) / 100
SI = (P×R×T) / 100
P = 5500
R = 3.5
T = 5
[substitute the values into the formula]
SI = (5500 × 3.5 × 5) / 100
SI = 96250 / 100
SI = 962.5
Total = Principal + Simple Interest
T = P + SI
T = 5500 + 962.5
T = 6462.5
The total value of the account after 5 years will be $6462.5
