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%

Answer:

A

Step-by-step explanation:

Given a sinusoidal function (sine function or cos function) in the form

y = A Cos (Bx), we can say that A is the amplitude.

Amplitude defines the function's maximum and minimum.

The maximum of this form of function is A and the minimum is -A.

The function given is y = -Cos(8x), so A is -1

Thus, maximum value is 1 and minimum value is -1.

Correct answer is A

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

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.

Answer:

V = 6, E = 9, F = 5 is the answer

The relation between vertices, edges, and faces is F + V = E + 2.

You have to count the faces, vertices and edges of a polyhedron.

A polyhedron is a 3-dimensional solid made by joining together polygons. Face: The flat surfaces that make up a polyhedron

Edges: It is a line segment formed when two faces meet up.

Vertices: It is the point of intersection of the edges of the polyhedron. Taking an example of Tetrahedron.

It has 4 faces, 4 vertices and 6 edges. Recall Euler's formula which states  F + V = E + 2

where F, V, and E represent the number of faces, edges, and vertices of the polyhedron respectively. Verifying the Euler's formula for tetrahedron F = 4V = 4E = 6

so 4 + 4 = 6 + 2

Hence we can verify the Euler's formula.

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.

The study doesn't prove a causation, only a correlation.  So we can conclude that cities with good air quality do not have traffic jams.

Answer:

Step-by-step explanation:

If an environmental organization releases a report where they state that the cities with the worst traffic jams have the worst air pollution, then we can deduct from this conclusion its anti-thesis, which is the cities without traffic jams have better air quality.

We deduct this because the given statement is a relation between two variables: traffic jam and air pollution. When we set a relationship between variable and we draw a conclusion, we have to determine all the deduction that can be made, like in this case.

Basically, the given relationship between variables is directly proportional, the more traffic jams, the more air pollution. Which also can be stated as the less traffic jams, the less air pollution.

Therefore, the conclusion that describes best the conclusion draw from the study is B. Cities with good air quality do not have traffic jams.

a) The recurrence relation is sₙ = sₙ₋₁ + sₙ₋₂ + ... + s₂ + s₁.

b) the initial condition s₂ = 1.

c) Clearly the solution to this recurrence relation and initial condition is sₙ = 2n-2 for all n >= 2.

Here, we have,

Let sₙ be the number of such sequences.

A string ending in n must consist of a string ending in something less than n, followed by an n as the last term.

Therefore the recurrence relation is sₙ = sₙ₋₁ + sₙ₋₂ + ... + s₂ + s₁.

This is equivalent to sₙ = 2sₙ-1.

b) We need two initial conditions if we use the second formulation above, s₁ = 1 and s₂ = 1.

There's one sequence which ends in 1,

and there is only the sequence 1,2 ending in 2.

If we use the first formulation above, then we can get by with just the initial condition s₂ = 1.

D. All three functions have the same rate of change.

Step-by-step explanation:

1. For the function f(x):

The rate of change is

[tex]\dfrac{f(\frac{3\pi}{2})-f(\pi)}{\frac{3\pi}{2}-\pi}=\dfrac{-4-0}{\frac{\pi}{2}}=-\dfrac{8}{\pi}.[/tex]

2. For the function g(x):

The rate of change is

3. For the function h(x):

The rate of change is

[tex]\dfrac{h(\frac{3\pi}{2})-h(\pi)}{\frac{3\pi}{2}-\pi}=\dfrac{-2-2}{\frac{\pi}{2}}=-\dfrac{8}{\pi}.[/tex]

All three functions have the same rate of change.

[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].

Since 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]

The 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.

Answer 2

Step-by-step explanation:

We start with (log to the base x of 8) = y and want to find the value of y.

Obviously the base here is x.

Therefore,

 (log to the base x of 8)            y

x                                           =  x

The quantity on the left side of this equation simplifies to 8.

                                 y

Then we have 8 = x

We'll need to solve this equation for y.  To do so, take the common log of both sides, obtaining:

                                               log 8

log 8 = y log x, so that   y =  -----------    This corresponds to given answer 2.

The sigma notation of the series is 8∑n=2 [1/2(1/2)^n-2]

Step-by-step explanation:

* Lets revise the meaning of sigma notation

- A series can be represented in a compact form, called summation or

 sigma notation.

- The Greek capital letter, ∑ , is used to represent the sum.

# Ex:

- The series 4 + 8 + 12 + 16 + 20 + 24 can be expressed 6Σ(n=1) 4n  

- The expression is read as the sum of 4n as n goes from 1 to 6

- The coefficient of n is 4 because the common difference is 4

- The variable n is called the index of summation.

# Look to the attached figure to more understand

* Now lets solve the problem

∵ The series is 1/2 + 1/4 + 1/8 + ........... + 1/128 and n = 2

- There is a constant ratio between each to consecutive terms

∴ The series is geometric

∴ a1 = a , a2 = ar , a3 = ar² , a4 = ar³ , ..........

∵ an = a(r)^n-1, where a is the first term, r is the common ratio and n

  is the position of the number in the series and the first n is 1

∵ 1/4 ÷ 1/2 = 12 , 1/8 ÷ 1/4 = 1/2

∴ The constant ratio is 1/2

∵ The first term is 1/2

∵ The last term is 1/128

∵ 1/128 = 1/2^7

∴ 1/128 = (1/2)^7

- There are seven terms in the sequence

∵ The n of the first term is 2

∴ The n of the last term = 7 + 1 = 8

* Now lets write the sigma notation

∴ 8∑n=2 [1/2(1/2)^n-2] ⇒ put them like the attached figure

- To generate the terms of the series given in sigma notation above,

  replace n by 2 , 3 , 4 , 5 , 6 , 7 , 8

Answer:

Each octave change requires a doubling of the frequency.

Therefore, one octave above 126.63 is 126.63 * 2 which equals

253.26

Step-by-step explanation:

The frequency of the note one octave above c4 would be 253.26 hz.

The frequency of the musical note C4 is about 126.63 hz

We need to find the frequency of the note one octave above C4.

Frequency is the number of occurrences of any repeating cycle per unit in time.

When we go up an octave, we double the original frequency.  

When we go down an octave, we divide the original frequency by two.

So, since C4's frequency is about 126.63 hz,

octave above = 2 x 126.63 hz

                        = 253.26 hz

Thus, The frequency of the note one octave above c4 would be 253.26 hz.

The first step is:

[tex]\frac{9m^2}{3m} - \frac{4m}{3m} - \frac{6}{3m}[/tex]

Now we must simplify the 3 fractions.

We know that by properties of the division of exponents of the same base:

[tex]\frac{a^n}{a^h}= a^{n-h}[/tex]

Then for the expression:

[tex]\frac{9m^2}{3m}[/tex]

In this case

[tex]a=m\\n=2\\h=1[/tex]

[tex]\frac{9m^2}{3m} = 3m^{2-1}=3m[/tex]

Then for the expression:

[tex]\frac{4m}{3m}[/tex]

[tex]a=m\\n=1\\h=1[/tex]

[tex]\frac{4m}{3m}= \frac{4}{3}m^{1-1}=\frac{4}{3}[/tex]

Then for the expression:

[tex]\frac{6}{3m}[/tex]

[tex]a=m\\n=0\\h=1[/tex]

[tex]\frac{6}{3m}=\frac{2}{m}[/tex]

Finally

To evaluate the triple integral, convert to cylindrical coordinates and use the given bounds. Plug in the limits of integration and calculate the integral.

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:
