Answer:
f(-2) = -5
Step-by-step explanation:
Actually, the function g(x) is irrelevant here. We need only evaluate the function f(x) = 3x + 1 at x = -2:
f(-2) = 3(-2) + 1 = -6 + 1 = -5
f(-2) = -5

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.

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
8
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

a1
.
5. What is the sum of an infinite geometric sequence whose first term is 192 and has common
ratio of 1
4
?
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

−7(x−3)−27=−6
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
