Answer:
3x² is a term in the numeratorx + 1 is a common factorThe denominator has 3 termsStep-by-step explanation:
You can identify terms and count them before you start factoring. Doing so will identify 3x² as a term in the numerator, and will show you there are 3 terms in the denominator.
When you factor the expression, you get ...
[tex]\dfrac{3x^2-3}{3x^2+2x-1}=\dfrac{3(x^2-1)}{(3x-1)(x+1)}=\dfrac{3(x-1)(x+1)}{(3x-1)(x+1)}[/tex]
This reveals a common factor of x+1.
So, the above three observations are true of this rational expression.

State if the triangles in each pair of similar. If so, State how you know they are similar and complete the similarity statement.
Answer:
Step-by-step explanation:
They are not similar. If they were, ∠LMF and ∠GHF would both have the same angle measure and they do not.
Final answer:
Mathematics question on similar triangles; triangles are similar if they have congruent corresponding angles and proportional sides obtained through AA, SSS, or SAS criterion. A similarity statement describes the correspondence of the vertices.
Explanation:
The question provided falls within the subject of Mathematics, specifically within the study of geometry and the concept of similar triangles. To determine if two triangles are similar, we must check if they have the same shape, which implies that their corresponding angles are equal and their corresponding sides are in proportion. In other words, two triangles are similar if their corresponding angles are congruent and the lengths of their corresponding sides are proportional. This can be verified by angle-angle similarity (AA), side-side-side similarity (SSS), or side-angle-side similarity (SAS). The similarity statement provides the order of correspondence of vertices between similar triangles.
When evaluating if triangles BAO and B1A1O are similar, we must compare their corresponding angles and sides. If the given information indicates that at least two angles of one triangle are congruent to two angles of another triangle (AA criterion), or that the sides are proportional (SSS or SAS criterion), then the triangles are similar. For instance, if ∠BAO ≅ ∠B1A1O and ∠BOA ≅ ∠B1O1A1, then by the AA criterion, the triangles are similar, and we could write the similarity statement as triangle BAO ∼ triangle B1A1O.
A man flies a kite at a height of 15 ft. The wind is carrying the kite horizontally from the man at a rate of 5 ft./s. How fast must he let out the string when the kite is flying on 32 ft. of string?
Answer:
4.4 ft/s
Step-by-step explanation:
Height = 15ft
Rate= 5 ft/s
Distance from the man to the kite= 32ft
dh/dt = 5 ft/s
h = √32^2 - 15^2
h = √ 1025 - 225
h = √800
h = 28.28ft
D = √15^2 + h^2
dD/dt = 1/2(15^2 + h^2)^-1/2 (2h) dh/dt
= h(225 + h^2)^-1/2 dh/dt
= (h / √225 + h^2)5
= (28.28 / √225 + 28.28^2)5
= (28.28 / √1024.7584)5
= (28.28/32)5
= 0.88*5
= 4.4 ft/s

if I'm in a plane flying at 512 miles per hour and a plane flies below me in the opposite direction, will it appear to fly slow or fast
Answer:
It appears to fly faster than its actual speed.
Step-by-step explanation:
In general, if talking about velocities, the direction of the movement should also be taken into account. For example, if two objects move in opposite directions, a person inside one object observes that the other one moving in the opposite goes faster than its actual speed (because the velocities are summed up). If they are moving in the same direction the opposite phenomenon is true (the velocities are subtracted).
Finally, in this example the planes move in opposite direction, therefore, a plane flying in the opposite direction will appear to fly faster.

A fly trapped inside a cubical box with side length 1 meter decides to relieve its boredom by visiting each corner of the box. It will begin and end in the same corner and visit each of the other corners exactly once. To get from a corner to any other corner, it will either fly or crawl in a straight line. What is the maximum possible length, in meters, of its path?
Answer:
(4 √ 3 + 4 √2 ) m
Step-by-step explanation:
The insect can travel from one corner directly to opposite corner in four different ways
each can be calculated using Pythagoras theorem
firstly for one face we need to calculate the diagonal
H² = 1² + 1² = 2
H = √2
then we calculate the diagonal opposite a corner
for example
A to H where A is at the bottom and H opposite A in another plane at the top in the cubical box
(Interior diagonal for A to H)² = √2² + 1² = 3
Interior diagonal from A to H = √ 3
there are four such corners, the fly will travel 4 √ 3 and it could also go 4 √2 diagonally to the the other corners
maximum possible length in meters = (4 √ 3 + 4 √2 ) m
A lazy high school senior types up application and envelopes to and different colleges, but puts the applications randomly into the envelopes. What is the expected number of applications that went to the right college?
To calculate the expected number of applications that went to the right college, we need to consider the probability of each application being placed correctly. Since the applications are placed randomly, each application has an equal chance of going to the right college. The expected number of applications that went to the right college is 1.
Explanation:To calculate the expected number of applications that went to the right college, we need to consider the probability of each application being placed correctly. Since the applications are placed randomly, each application has an equal chance of going to the right college. Let's say there are n applications and n colleges.
The probability of a specific application going to the right college is 1/n. Therefore, the expected number of applications that went to the right college can be calculated as:
Expected number = Total number of applications * Probability of an application going to the right college
Expected number = n * (1/n)
Expected number = 1
The expected number of applications that went to the right college is 1. This means that, on average, one application will go to the right college.
Maggie can paint a fence in 9 hours, but Tom needs 12 hours to paint the same fence. How long does it take them to paint the fence if they work together? Round to the nearest tenth.
Working together, Maggie and Tom can paint the fence in 5.1 hours
Solution:Given that,
Maggie can paint a fence in 9 hours
So in 1 hour maggie paints, [tex]\frac{1}{9}[/tex] of the house
Tom needs 12 hours to paint the same fence
So in 1 hour, tom can paint [tex]\frac{1}{12}[/tex] of the house
To find: time taken to paint the fence if they work together
Let "a" be the time taken to paint the fence if they work together
So working together, in 1 hour, they can paint [tex]\frac{1}{a}[/tex] of the house
We can frame a equation as:
To see how much of the fence they can paint together in one hour, we add these together.
[tex]\frac{1}{9} + \frac{1}{12} = \frac{1}{a}[/tex]
[tex]\frac{1}{a}[/tex] is how much of the fence they can paint together in one hour. Therefore "a" is the number of hours it will take them both to paint the fence
On solving,
[tex]\frac{12 + 9}{12 \times 9} = \frac{1}{a}\\\\\frac{1}{a} = \frac{21}{108}\\\\a = \frac{108}{21} = 5.1428[/tex]
So working together, Maggie and Tom can paint the fence in 5.1 hours
Let alpha and beta be conjugate complex numbers such that frac{\alpha}{\beta^2} is a real number and alpha - \beta| = 2 \sqrt{3}. Find alpha.
Final answer:
To find the value of alpha given that alpha and beta are conjugate complex numbers, and alpha/beta^2 is real, we can use the equation |alpha - beta| = 2√3. We can substitute alpha = a + bi and beta = a - bi, and solve for a and b to find the value of alpha.
Explanation:
Let α and β be conjugate complex numbers such that α/β² is a real number and |α - β| = 2√3. We need to find the value of α.
Since α and β are conjugate complex numbers, they have the form α = a + bi and β = a - bi, where a and b are real numbers. Substituting these values into the given equation, we get:
|α - β| = |(a + bi) - (a - bi)| = |2bi| = 2|b| = 2√3
From this, we can conclude that |b| = √3. Since |b| is the absolute value of b, it is always positive. Therefore, we have two options: b = √3 or b = -√3.
If b = √3, then α = a + √3i. We can substitute this into the equation α/β² to check whether it is a real number.
α/β² = (a + √3i)/(a - √3i)² = (a + √3i)/(a² - 2a√3i - 3) = [(a(a² - 3) + √3i(3a - a²)] / (a² - 2a√3i - 3)
This expression is not a real number, so b ≠ √3.
If b = -√3, then α = a - √3i. We can substitute this into the equation α/β² to check whether it is a real number.
α/β² = (a - √3i)/(a + √3i)² = (a - √3i)/(a² + 2a√3i + 3) = [(a(a² + 3) - √3i(3a + a²)] / (a² + 2a√3i + 3)
This expression simplifies to (a(a² + 3) - √3(3a + a²))/ (a² + 3) = a - √3(2a + 1)/ (a² + 3)
For this expression to be a real number, the imaginary term √3(2a + 1) must be equal to 0. So, we have √3(2a + 1) = 0.
Solving this equation, we get 2a + 1 = 0, which implies a = -0.5.
Therefore, the value of α is α = -0.5 - √3i.

A rectangular lot whose perimeter is 260 ftis fenced along three sides. An expensive fencing along the lot's length cost $ 18per foot. An inexpensive fencing along the two side widths costs only $ 3per foot. The total cost of the fencing along the three sides comes to $ 1800.What are the lot's dimensions?
Step-by-step explanation:
A rectangular lot whose perimeter is 260 ft is fenced along three sides. An expensive fencing along the lot's length cost $ 18per foot. An inexpensive fencing along the two side widths costs only $ 3per foot.
So we have
l + 2 w = 260 -------------------eqn 1
And total cost is 1800 $
That is
18 l + 2 x 3 w = 1800
3l + w = 300 -------------------eqn 2
eqn 2 x 2
6l + 2w = 600 -------------------eqn 3
eqn 3 - eqn 1
6l + 2w - l - 2w = 600 - 260
5l = 340
l = 68 ft
Substituting in eqn 1
68 + 2 w = 260
2w = 192
w = 96 ft
Lot's dimension is 68 ft x 96 ft

Final answer:
To complete the statement describing the expression (a+b)(d+e)(a+b)(d+e), we expand it by multiplying each term. Simplifying the expression, we get a²*d² + 2a²de + 2abde + b²e².
Explanation:
To complete the statement describing the expression (a+b)(d+e)(a+b)(d+e), we need to expand it. This can be done by multiplying each term in the first factor by each term in the second factor and then multiplying the result by the third factor. So the expression becomes:

Find a formula C(x,y,z) that gives the cost of materials for a closed rectangular box, with dimensions in feet. Assume that the material for the top and bottom costs $3 per square foot and the material for the sides costs $5 per square foot. Show all work in steps clearly.
Answer:
C(x,y,z)=6*x*y+10*x*z+10*y*z
Step-by-step explanation:
Lets assume that x is width, y is length and z is height. To find the area of the top and bottom surfaces we need to simply multiply length and width.
x*y
There is a 2 surface exist (top and bottom) we need to multiply this value with 2 again.
2*x*y
and the cost is 3$ for per square foot and the cost for top and bottom is:
6*x*y$
Surface areas of side surfaces are multiply of width, height and length, height:
x*z+y*z
There are 4 side surfaces exist. Therefore the are need to be multiply with 2.
2*x*z+2*y*z
and the cost is 5$ for per square foot and the cost for side surfaces is:
10*x*z+10*y*z
Total equality for cost is C(x,y,z)=6*x*y+10*x*z+10*y*z
To calculate the cost of materials for a closed rectangular box, use the formulas C(x,y) = 2 * (3xy) for the top and bottom and C(z,y) = 2 * (5zy) for the sides. Then, find the total cost by adding the costs together.
Explanation:To calculate the cost of materials for a closed rectangular box, we need to consider the dimensions of the box. Let's assume the dimensions are given as x, y, and z in feet.
The cost for the top and bottom parts of the box can be calculated using the formula C(x,y) = 2 * (3xy), where 3 is the cost per square foot and xy is the area of the top and bottom.
The cost for the side parts of the box can be calculated using the formula C(z,y) = 2 * (5zy), where 5 is the cost per square foot and zy is the area of the sides.
Finally, the total cost of materials for the box can be found by adding the costs for the top and bottom parts to the cost of the side parts: C(x,y,z) = C(x,y) + C(z,y).

What is the total interest earned in two years on an account containing $500 at 3.5% interest, compounded annually?
$35.61
$35.16
$35.00
$36.51
Answer: Compound interest is $36.61
Step-by-step explanation:
Initial amount deposited into the account is $500 This means that the principal,
P = 500
It was compounded annually. This means that it was compounded once in a year. So
n = 1
The rate at which the principal was compounded is 3.5%. So
r = 3.5/100 = 0.035
It was compounded for 2 years. So
t = 2
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 500 (1+0.035/1)^1×2
A = 500(1.035)^2 = $535.61
Compound interest = 535.6 - 500 = $35.61
Ron walks 0.5 mile on a track in 10 minutes. Stevie walks 0.25 mile on the track in 6 minutes find the unit rate for each walker in miles per hour. Who is faster?
Answer:
Ron's speed = 3 miles/hour
Stevie's speed = 2.5 miles/hour
On comparing we see Ron is walking faster than Stevie.
Step-by-step explanation:
Given:
Ron takes 10 minutes to walk on a track to cover a distance of 0.5 miles
Stevie takes 6 minutes to walk on a track to cover a distance of 0.25 miles
To find their unit rates in mile per hour and choose the faster one.
Solution:
Unit rate in miles per hour signifies their speeds. Thus, we will find out their speeds.
Ron:
Distance= 0.5 miles
Time = 10 minutes = [tex]10\ min\times \frac{1\ hr}{60\ min}=\frac{1}{6}[/tex] hours
Speed = [tex]\frac{Distance}{Time}=\frac{0.5}{\frac{1}{6}}=0.5\times6=3\ miles/hour[/tex]
Stevie
Distance = 0.25 miles
Time = 6 minutes = [tex]6\ min\times \frac{1\ hr}{60\ min}=\frac{1}{10}[/tex] hours
Speed = [tex]\frac{Distance}{Time}=\frac{0.25}{\frac{1}{10}}=0.25\times10=2.5\ miles/hour[/tex]
Thus, we have
Ron's speed = 3 miles/hour
Stevie's speed = 2.5 miles/hour
On comparing we see Ron is walking faster than Stevie.
Assume that a surveyor stands at the top of a mountain that is "h" feet tall. If the distance (in feet) that he can see is defined by d = 3200.2 SQRT(h), then answer the following. (a) How far can the surveyor see from the top of a 2000-foot mountain? (b) How tall is the mountain, if the surveyor can see 15 miles? (Note: 1 mile equals 5280 feet.)
Answer:
a) d = 143,117 ft
b) h = 612.45 ft
Step-by-step explanation:
If height of the mountain = h
And distance till the surveyor can see = d = 3200.2 SQRT (h)
Refer to attached file for graphical representation
Then;
A) If h=2000 ft
Then d =3200.2 √ (2000)
d = 3200.2 (44.72)
d = 143,117 ft
B) If d = 15 miles
1mile = 5280 ft
15 mile = 15*5280
15 mile = 79,200 ft
Therefore;
d = 79,200 ft
Since,
d =3200.2 √ (h)
79,200 = 3200.2 √ (h)
79200/3200.2 =√ (h)
√ (h) = 24.75
{√ (h)} ² = (24.75) ²
h = 612.45 ft
Calculate the simple interest paid on a loan of $544 at 3% for three months.
$48.96
$4.80
$4.90
$4.08
Answer:
Step-by-step explanation:
Answer: interest at the end of 3 months is $4.08
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
From the information given
T = 3 months = 3/12 = 0.25 years
P = $544
R = 3%
Therefore
I = (544 × 3 × 0.25)/100
I = 408/100
I = 4.08

Office Furniture Makers, Inc. uses machines to produce high quality office chairs for other firms. The initial cost of one customized machine is $750,000. This machine costs $12,000 a year to operate. Each machine has a life of 3 years before it is replaced. What is the equivalent annual cost of this machine if the required return is 10 percent? (Round your answer to whole dollars.)
The equivalent annual cost of the machine, considering a 10% return, is approximately $309,535 per year.
Explanation:First, accumulate the total cost over the lifespan of the machine which is $750,000 (initial cost) + ($12,000 * 3 years) = $786,000. The equivalent annual cost can be calculated using the formula for the present value of an annuity: PV = PMT [(1 - (1 + r)^-n ) / r], where 'PMT' is the payment per period, 'r' is the rate of return, and 'n' is the number of periods. Rearrange to calculate PMT: PMT = PV * r / (1 - (1 + r)^-n). Substituting in given values gives us, PMT = $786,000 * 0.1 / [1 - (1 + 0.1)^-3] = $309,535/year.
