The difference in the total costs of the 12 pairs of shoes between the two sites is $46.77,

Total cost is the sum up cost for all the individual process. we can find it by adding the cost for each steps.

In the given ques,

Super Sports is offering a 20% discount.

and shoes were originally priced at $72.50 and that a 6.5% sales tax will be applied.

On Double Dribbles, the same shoes were on for $54.75, and a 9% is added and has an extra $5.99 for shipping.

i.e. we  have to find the difference in the total costs..

Now we have to multiply 12 by 72.50. The answer to that is 870. Next, we need to multiply 8 by 870 and divide it by 10. The answer to that is 696. Then, we need to add the price and the tax. The price will be 100%, and the tax will be 6.5%. 100 + 6.5 = 106.5. After that, we need to 106.5 by 100. The answer it that is 1.065. Now do  times 1.065 by 696. And the answer to that is $741.24.

Do the same for other store.  The answer to it is 788.01.

Thus, making Super Sports a better deal.

As, we need to find the difference. So, 788.01 - 741.24 = $46.77.

The volume of the cylinder having radius 6 feet and height 12 feet is  1357.7 cubic feet.

Volume is referred to as the area occupied within an object's three-dimensional space.

Given that,

The radius of cylinder r = 6 feet,

And the height of the cylinder h = 12 feet.

To find the volume of the cylinder, use formula,

Volume of cylinder = π × r² ×h

= (22/7) × 6 × 6 × 12

= (22/7) × 432

= 9504 / 7

= 1357.7 cubic feet.

The required volume of the cylinder is 1357.7 cubic feet.

Hi there! :)

Answer:

(a) ≈ 3.61 cm.

(b) = 2.77 cm².

Use the Pythagorean theorem to solve for the side-length of DC. Let "s" represent the side-lengths:

s² + s² = 26

2s² = 26

Divide both sides by 2 to simplify:

s² = 13

Take the square root of both sides:

s = √13 ≈ 3.61 cm.

------------------------------------------------------------------------------------------

Calculate the shaded region by subtracting the area of the arc from the area of the square. DC represents the radius of the circle that the arc is apart of. Therefore:

Area of arc AC = 1/4 (πr²)

Solve for the area:

AC = 1/4 (π · (3.61)²)

AC = 1/4 (40.92)

AC = 10.23 cm²

Subtract this area from the area of the square (A = s²)

A = (√13)²

A = 13 cm²

13 - 10.23 = 2.77 cm²

Therefore, the solutions are:

(a) ≈ 3.61 cm.

(b) = 2.77 cm².

Step-by-step explanation:

We need to find the inverse of the function gof (x). First we need to find the composite function gof (x) which is given by:

\(g(f(x)) = g(3x - 6)\)

= \((1/3)(3x - 6) + 1\)

= x - 1 + 1

= x

Thus,

gof (x) = x.

Now we need to find the inverse of the function gof (x) to obtain

\((gof)^-1 (x).\)

We have gof (x) = x

which implies\((gof)^-1 (x)\)

= gof (x)^-1

= x^-1

= 1/x,

x ≠ 0

Therefore,

\((gof)^-1 (x) = 1/x\)

which is option (3) (x+1) since 1/x can be written as 1/(x+1-1), where (x+1-1) is the denominator of 1/x.

Hence, the correct option is (3).

To find (g(f))^-1 (x), substitute the expression for f(x) into g(x) and simplify. The composition of g(f) is x and its inverse is also x. Therefore, (g(f))^-1 (x) equals x.

To find (g(f))^-1 (x), we need to first find the composition of g(f) and then find its inverse. Start by substituting the expression for f(x) into g(x): g(f(x)) = g(3x-6) = \frac{1}{3}(3x-6) + 1 = x - 1 + 1 = x. So, g(f(x)) = x. Now, to find the inverse of g(f), we switch the x and y variables and solve for y: y = x. Therefore, (g(f))^-1 (x) = x.

Step-by-step explanation:

ABCD is a rectangle.

It's length l = 5 units

Perimeter of ABCD = 2(l + w) = 2(5 + 3) = 2*8 = 16 units

Area of ABCD = 5*3 = 15 squared units.

In a family with five girls and the probability of a boy being born is 1/2, the probability of the next child being a boy is still 1/2.

The previous births do not affect the probability of the next birth since each birth is an independent event.

The probability of an event occurring is determined by the ratio of the number of favorable outcomes to the total number of possible outcomes. In this case, the event of interest is the birth of a boy.

Since each birth is an independent event, the probability of having a boy on any given birth is always 1/2, regardless of the previous children born.

In the given scenario, the family already has five girls. This information is not relevant to the probability of the next child being a boy. The gender of the previous children does not affect the probability of the next child being a boy or a girl.

Therefore, the probability of the next child being a boy remains 1/2, as it is for any independent birth event.

Answer:

The answer is 13 because that is the month that both memberships will cost the same amount of money.

Step-by-step explanation:

First translate the question into equations.

Total Gym:

100+20m

Where "m" equals the amount of months

Fitness Plus Elite

35+25m

Where "m" equals the amount of months

Set the equations equal to each other and solve for m, or the amount of months it takes to get the same price for each membership.

100+20m=35+25m Subtract 35 from both sides.

65+20m=25m Subtract 20m from both sides

65=5m Divide both sides by 5

13=m Both memberships will cost the same amount of money at 13 months. You can substitute this value into the original equations to check your work.

100+20(13)=$360

35+25(13)=$360

The answer is 13 because that is the month that both memberships will cost the same amount of money.

The  values of x will f(x) > 0 for x < 0, and f(x) < 0 for -6 < x < 0 and x > -6.

To determine the values of x for which f(x) > 0, we need to find the intervals where the function is positive. Let's analyze the function f(x) = x*-x³-6x².

First, let's factor out an x from the expression to simplify it: f(x) = x(-x² - 6x).

Now, we can observe that if x = 0, the entire expression becomes 0, so f(x) = 0.

Next, we analyze the signs of the factors:

1. For x < 0, both x and (-x² - 6x) are negative, resulting in a positive product. Hence, f(x) > 0 in this range.

2. For -6 < x < 0, x is negative, but (-x² - 6x) is positive, resulting in a negative product. Therefore, f(x) < 0 in this range.

3. For x > -6, both x and (-x² - 6x) are positive, resulting in a negative product. Thus, f(x) < 0 in this range.

The interval of convergence for the given power series is (2, 8).

To find the interval of convergence for the given power series. We have the power series:

∑(n=2 to ∞) ((x-5)ⁿ)/(3ⁿ)

To find the interval of convergence, we'll use the Ratio Test. For the Ratio Test, we need to compute the limit:

L = lim (n → ∞) |(a_(n+1)/a_n)|

For our series, a_n = ((x-5)ⁿ)/(3ⁿ). Therefore, a_(n+1) = ((x-5)(n+1))/(3(n+1)). Now, let's compute the ratio:

|(a_(n+1)/a_n)| = |(((x-5)(n+1))/(3(n+1))) / (((x-5)ⁿ)/(3ⁿ))|

Simplify the expression:

|(a_(n+1)/a_n)| = |(x-5)/3|

The series converges if L < 1. So we have:

|(x-5)/3| < 1

Now, we'll solve for x to find the interval of convergence:

-1 < (x-5)/3 < 1

Multiply each term by 3:

-3 < x-5 < 3

Option B is correct, 4 and 3/10 hours  will Mrs. Nygaard need to work over the weekend to finish grading the projects.

A fraction represents a part of a whole.

To find the total amount of time Mrs. Nygaard has available during the week to grade projects, we need to add up the hours for each day:

1 and three-fourths + 1 and one-half + 1 and one-fifth + 2 + 1 and one-fourth = 7 and five-tenths hours

This means that Mrs. Nygaard has 7.5 hours during the week to grade projects.

If she needs 12 hours to grade all the projects, then she will need to work for an additional:

The travel times for Bus 14 are more tightly clustered around the median compared to Bus 47.

In mathematics and statistics, range is a measure of the spread or dispersion of a set of data, and it represents the difference between the largest and smallest values in a dataset.

To calculate the range of a dataset, you simply subtract the minimum value from the maximum value. For example, if you have a dataset of test scores: 65, 72, 80, 85, 92, 98. The highest score is 98, and the lowest score is 65. Therefore, the range of the test scores is 98 - 65 = 33.

While range is a simple and easy-to-calculate measure of dispersion, it can be sensitive to outliers or extreme values in the dataset, which may not be representative of the overall data. Other measures of dispersion, such as variance or standard deviation, may be more appropriate in some cases.

To determine which bus is the most consistent, we need to use a measure of variability. The most appropriate measure of variability to use in this case is the interquartile range (IQR), which is the difference between the first and third quartiles.

For Bus 47, the first quartile is 10, and the third quartile is 18. So the IQR is 18 - 10 = 8.

For Bus 14, the first quartile is 12, and the third quartile is 18. So the IQR is 18 - 12 = 6.

Since the IQR for Bus 47 is larger than the IQR for Bus 14, we can conclude that Bus 14 is more consistent in terms of travel times to school. This means that the travel times for Bus 14 are more tightly clustered around the median compared to Bus 47.

The expression for the number of bacteria after t hours is N(t) = 50e\(^(0.4427t)\) , rounded to four decimal places.

Let N(t) be the number of bacteria after t hours.

Since the culture grows at a rate proportional to its size, we can write:

dN/dt = kN

where k is the proportionality constant.

This is a separable differential equation, which we can solve by separating the variables and integrating:

dN/N = k dt

ln(N) = kt + C

where C is the constant of integration.

To find the value of C, we use the initial condition that the culture initially contains 50 cells:

ln(50) = k(0) + C

C = ln(50)

Substituting C into the previous equation, we get:

ln(N) = kt + ln(50)

Taking the exponential of both sides, we obtain:

N = e\(^(kt + ln(50)) = 50e^(kt)\)

Now we need to find the value of k. We know that after 1.5 hours, the population has increased to 825:

N(1.5) = 825

Substituting this into the previous equation, we get:

825 = 50\(e^(1.5k)\)

Taking the natural logarithm of both sides, we obtain:

ln(825/50) = 1.5k

k = ln(825/50) / 1.5

k ≈ 0.4427

Finally, substituting this value of k into the expression we obtained for N(t), we get:

N(t) = 50e\(^(0.4427t)\)

Therefore, the expression for the number of bacteria after t hours is N(t) = \(50e^(0.4427t)\), rounded to four decimal places.
