Reflecting /\ (triangle) LMN across the horizontal line y = -1, we get its image /\ (triangle) L' M' N'. Suppose LL', MM', NN' intersect the line of reflection at S, T, and U as shown below.
[tex]\overline{LL'}, \ \overline{MM'} \ and \ \overline{NN'}[/tex] are each perpendicular to the line of reflection
This option is the only one that is correct. The line of reflection is [tex]y=-1[/tex]. When we talk about reflection, we are talking about reflecting across a line, or axis. Reflecting a shape means looking at the mirror image on the other side of the axis. So in this case, this mirror is the line of reflection. As you can see, these three segments [tex]\overline{LL'}, \ \overline{MM'} \ and \ \overline{NN'}[/tex] form a right angle at the point each segment intersects the line [tex]y=-1[/tex].
b) Find each lengthSince the line [tex]y=-1[/tex] is an axis that allows to get a mirror image, therefore it is true that:
[tex]\overline{LS}=\overline{L'S} \\ \\ \overline{MT}=\overline{M'T} \\ \\ \overline{NU}=\overline{N'U}[/tex]
To find those values [tex]\overline{LS}[/tex], count the number of units you get from the point S to L, which is 3 units. Do the same to find [tex]\overline{MT}[/tex] but from the point T to M, which is 6 units and finally, for [tex]\overline{NU}[/tex] but from the point U to N, which is 4 units. Therefore:
[tex]\overline{LS}=\overline{L'S}=3 \ units \\ \\ \overline{MT}=\overline{M'T}=6 \ units \\ \\ \overline{NU}=\overline{N'U}=4 \ units[/tex]
c) Correct StatementThe line of reflection is the perpendicular bisector of each segment joining a point and its image.
A bisector is the line dividing something into two equal parts. In this case, the line of reflection divides each segment into two equal parts and is perpendicular because this line form a right angle with each segment. As we demonstrated in a) each segment is perpendicular to the line of reflection, so the first statement is false. On the other hand, each side of the original triangle is not perpendicular to its image and this is obvious when taking a look at the figure. Finally, as we said the line of reflection is perpendicular to each of the mentioned segments, so they can't be parallel as established in the last statement.
For the following pair of lines, identify the system by type.
A) consistent
B) equivalent
C) inconsistent
ANSWER
C) inconsistent
EXPLANATION
The given system is inconsistent.
The two lines are parallel and have distinct y-intercepts.
This means that the two lines will never meet.
Since the two lines have no points of intersection, it means the system of equations they represent has no solution.
Therefore the system is inconsistent.
The correct choice is C
Answer:
If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.

Wahaj buys a pizza for rs 800.A week later,the same piza costs rs 900.When wahaj asks the manger for the reason ,he explain that the government has imposed a general sales tax on all resturants .What is the general sale tax percentage
Answer:
12.5%
Step-by-step explanation:
The price increased from 800 to 900. So what is the PERCENTAGE INCREASE??
The increase is 900 - 800 = 100
To find this in terms of original, we need to divide 100 by 800 and multiply by 100 to get the "percentage". Let's do it:
[tex]\frac{100}{800}*100=12.5[/tex]
So the increase is 12.5% and thus the general sales tax is 12.5%
Final answer:
The general sales tax percentage imposed on the pizza price is 12.5%, calculated by dividing the increase in price by the original price and multiplying by 100.
Explanation:
When Wahaj experienced an increase in price from rs 800 to rs 900 for the same pizza after a week, this is due to the imposition of a general sales tax by the government. To calculate the percentage rate of the sales tax, we can compare the two prices.
The original price of the pizza was rs 800. A week later, the price rose to rs 900. The difference between the two prices, which is rs 100, represents the amount of the sales tax added to the original price. The percentage rate of this sales tax can be calculated as follows:
Sales Tax Percentage = (Amount of Sales Tax / Original Price) x 100%
Using the figures we have: Sales Tax Percentage = (100 / 800) x 100% = 0.125 x 100% = 12.5%
Therefore, the general sales tax percentage imposed on the restaurant is 12.5%
true or false the angle
Answer:
Second option: False
Step-by-step explanation:
You need to use the following identity:
[tex]sin\alpha=\frac{opposite}{hypotenuse}[/tex]
Let be "x" the lenght of the buildings's shadow.
[tex]opposite=x[/tex] (Lenght of building's shadow)
You can observe in the figure that:
[tex]\alpha=75\°\\\\hypotenuse=50ft[/tex]
Substitute these values into [tex]sin\alpha=\frac{opposite}{hypotenuse}[/tex] and solve for ""x":
[tex]sin(75\°)=\frac{x}{50}\\\\(50)(sin(75\°))=x\\\\x=48.29\°[/tex]
Therefore, the length of its shadow IS NOT 12.94 feet.
For accounting purposes, the value of assets (land, buildings, equipment) in a business are depreciated at a set rate per year. The value, V(t) of $393,000 worth of assets after t years, that depreciate at 15% per year, is given by the formula V(t) = Vo(b)t. What is the value of Vo and b, and when rounded to the nearest cent, what are the assets valued at after 7 years?
Vo = $393,000, b = 0.15, and the value after 7 years is $0.67
Vo = $393,000, b = 1.15, and the value after 7 years is $108,543.57
Vo = $393,000, b = 0.85, and the value after 7 years is $47,721.43
Vo = $393,000, b = 0.85, and the value after 7 years is $125,986.80
Answer:
So, option d is correct i.e,
V₀ = $393,000, b = 0.85, and the value after 7 years is $125,986.80
Step-by-step explanation:
The formula given is V(t)=V₀(b)^t
The value of V₀ (the actual worth) is:
V₀ = $393,000
The value of b is :
b= (1-15%) = (1-0.15) = 0.85
Value of assets after 7 years is:
t= 7, V₀ = $393,000, b=0.85
putting values in formula:
V(t) = Vo(b)^t.
V(7)= $393,000 * (0.85) ^ 7
V(7)= $393,000 * (0.320)
V(7)= $125986.80
So, option d is correct i.e,
Vo = $393,000, b = 0.85, and the value after 7 years is $125,986.80

To evaluate the triple integral, convert to cylindrical coordinates and use the given bounds. Plug in the limits of integration and calculate the integral.
Explanation:To evaluate the triple integral ∫ 5x dv, where E is bounded by the paraboloid x = 7y^2 + 7z^2 and the plane x = 7, we can use cylindrical coordinates. Let's express x in terms of y and z:
x = 7y^2 + 7z^2
Substitute this expression for x in the integral:
∫5x dv = ∫35(y^2 + z^2) dv
Now, convert the integral to cylindrical coordinates:
∫35(r^2sin(θ)rdrdθdz
Since the region E is bounded by x = 7, the limits of integration for r and z are 0 to 7. For θ, the limits are 0 to 2π. Plug in these limits and evaluate the triple integral to find the answer.

A garage door that is 16 feet wide and 7 feet high is being painted the door have three windows that will not be painted each rectangular window is 1 foot high and 3 feet wide what area of the garage door will be painted
Answer:
103 ft
Step-by-step explanation: First, you find the area of the garage door as a whole (112 ft). Then, you find the area of each the three windows and add them together (their total area together is 9 ft). Lastly, you subtract this sum from the area of the whole door and the answer that you will get is 103 ft. Hope this helps :)
The area of the garage door to be painted, excluding the rectangular window is 103 ft².
To find the area of the garage door that will be painted:
Calculate the total area of the garage door: 16 ft wide x 7 ft high = 112 ft².
Subtract the area of the three windows: 3 windows x (3 ft wide x 1 ft high) = 9 ft².
The area to be painted is 112 ft² - 9 ft² = 103 ft².
Determine whether the function is periodic. If it is periodic, find the period.
f(x) = 7 sin3 x
Answer:
The period is 2pi
Step-by-step explanation:
A function is said to be periodic if there exists a T for which f(x+T)=f(x). In this case, the function is f(x) =7sin^3(x).
The period of sin(x) = 2pi. Then, in this case, no matter if the sin is elevated to a power of three, the period will remain the same.
Let's prove it:
f(x) =7sin^3(0) = 0
f(0 + 2pi) = f( 2pi) = 7sin^3(2pi) = 0.
Then, there exists a T for which f(x+T)=f(x) and it's T=2pi.

A number is chosen at random from the first 20 integers. Find the probability that the number is a multiple of 3.
Answer:
3/10
Step-by-step explanation:
Multiples of 3: 3,6,9,12,15,18
There are 6 in the numbers 1-20
P(multiple of 3) = number of "multiples of 3" / total
= 6/20
=3/10
Final answer:
The probability that a number chosen at random from the first 20 integers is a multiple of 3 is 3/10 or 30%.
Explanation:
The student is asking to find the probability that a number chosen at random from the first 20 integers is a multiple of 3. To solve this, we first identify the multiples of 3 within the first 20 integers. They are 3, 6, 9, 12, 15, and 18, a total of 6 numbers. The total number of possible outcomes when choosing one number from the first 20 integers is 20.
The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Therefore, the probability of choosing a multiple of 3 is 6/20, which simplifies to 3/10 or 0.3. This means there is a 30% chance of choosing a multiple of 3 from the first 20 integers.

If you rewrite the quadratic to standard form (by subtracting the right-side expression), you get ...
x^2 -4x +5 = 0
Using the hint, the discriminant is b^2-4ac = (-4)^2-4(1)(5) = 16 -20 = -4. It is negative, so both roots will be complex.

2. The (rational) number "b" is the opposite of the sum of the zeros. If one zero is rational, the other root must be. The difference of rational numbers is rational.
Choices A and D are identical, so both are correct. Perhaps a typo?

We can also consider the discriminant in problem 2. The roots of the quadratic are the sum (or difference) of -b and the square root of the discriminant, all divided by 2a. Any one root can only be rational if the square root is rational. In that case, the other root will be rational as well.
Dominique paints faces on annual carnival her goal this year is to earn $100 she spends $15 on supplies and we'll work for 2.5 hours how much will she need to earn in dollars per hour in order to reach your goal
Answer:
46
Step-by-step explanation:
Final answer:
Dominique needs to earn $34 per hour to reach her goal of $100, after accounting for her $15 expenses on supplies, for the 2.5 hours she will be working at the carnival.
Explanation:
To calculate how much Dominique needs to earn per hour to reach her goal of $100 after spending $15 on supplies, we first need to subtract the cost of supplies from her earnings goal:
$100 - $15 = $85
This leaves us with $85 that she needs to earn while working for 2.5 hours. By dividing $85 by the 2.5 hours, we can find out her required hourly earning rate.
So, the calculation will be $85 ÷ 2.5 hours = $34 per hour.
Therefore, Dominique will need to earn $34 per hour during her 2.5 hours of work to reach her goal of $100 after spending $15 on supplies.
