Answers

The expression ((t − 9) · (t² − 9) · (t³ − 9) · (t⁴ − 9) · (t⁵ − 9) · (t⁶ − 9) · (t⁷ − 9) can be written in terms of product notation as Π⁷k=1 \((t^k - 9)\).

As per the question, we can write the expression as:

(t − 9) · (t² − 9) · (t³ − 9) · (t⁴ − 9) · (t⁵ − 9) · (t⁶ − 9) · (t⁷ − 9)

Using product notation, we can write this as:

Π⁷k =1 \((t^k - 9)\)

where Π represents the product of terms, k is the index of the product, and the subscript 7 indicates that the product runs from k = 1 to k = 7.

Therefore, the expression ((t − 9) · (t² − 9) · (t³ − 9) · (t⁴ − 9) · (t⁵ − 9) · (t⁶ − 9) · (t⁷ − 9) can be written in terms of product notation as Π⁷k=1 \((t^k - 9)\).

Determine the amplitude or Period as requested.
Period of y= -2 sin x

Answers

amplitude: 2

period: 2pi

The equation for a sin function is:

\(y = a \sin(b(x - c) ) + d\)

a = the amplitude

b = the period

c = the horizontal shift

d = the vertical shift

the equation to find the period of a sin function is:

\(period = \frac{2\pi}{b} \)

note: the amplitude is always a positive number, if there is a negative sign in front of it then that means it reflects over the x-axis.

lena is going to rent a truck for one day. there are two companies she can choose from, and they have the following prices. company a charges and allows unlimited mileage. company b has an initial fee of and charges an additional for every mile driven. for what mileages will company a charge less than company b? use for the number of miles driven, and solve your inequality for .

Answers

Therefore, company A will charge less than company B for any mileage greater than 65 miles.
To help you with your question, I need the specific prices for both companies, as well as any additional information you can provide about the charges.

To solve for the mileages at which company A will charge less than company B, we can set up the following inequality:
A < B
where A is the cost of renting from company A and B is the cost of renting from company B. We can plug in the given information to get:
x ≤ A
x > B = y + 40z
where x is the number of miles driven, y is the initial fee for company B, and z is the additional cost per mile for company B.
Now we can substitute the given values to get:
x ≤ A
x > y + 40z
For company A, the cost is a flat rate with unlimited mileage, so A is just the cost listed for one day of rental. Let's say that cost is $100.
For company B, the initial fee is $50 and the additional cost per mile is $0.25. So:
y = 50
z = 0.25
Now we can plug in these values and solve for x:
x ≤ 100
x > 50 + 40(0.25)
x > 65
Therefore, company A will charge less than company B for any mileage greater than 65 miles.
To help you with your question, I need the specific prices for both companies, as well as any additional information you can provide about the charges.

Carrie works 40 hours a week spend 15% her tome in the register 30% her time greeting customers remainder of her time I'm maintenance what % is her time spent in maintenance

Answers

Answer:

\(Maintenance = 55\%\)

Step-by-step explanation:

Given

\(Time = 40\ hours\)

\(Register = 15\%\)

\(Greetings = 30\%\)

Required

Percentage of time spent in maintenance;

From the given parameters,She spends the rest of her time in maintenance;

This implies that

\(Register + Greetings + Maintenance= 100\%\)

Substitute 15% for Register and 30% for Greetings

\(15\% + 30\% + Maintenance= 100\%\)

\(45\% + Maintenance= 100\%\)

Subtract both sides by 45%

\(45\% - 45\% + Maintenance = 100\% - 45%\)

\(Maintenance = 100\% - 45%\)

\(Maintenance = 55\%\)

Hence, the percentage of time spent in Maintenance is 55%

growth or decay by what precent?

Answers

The function f(x) = 600(0.75)^x. is a decay function by 25%

How to graph the function?

The equation of the function is given as

f(x) = 600(0.75)^x.

The above function is an exponential function

An exponential function is represented as

y = ab^x

When f(x) = 600(0.75)^x. and y = ab^x are compared, we have

b = 0.75

The value of b in this case is the factor

Also if b is less than 1, then the function is a decay function

0.75 is less than 1

So, the function represents a decay function

The decal percentage is then calculated as

Decay = 1 - b

So, we have

Decay = 1 - 0.75

Evaluate

Decay = 25%

Hence, the function is a decay function

if there were 12 more skaters who brought their own skates than skaters who rented skates, how many skaters were there altogether?

Answers

According to the ratio 5:3 the skaters that were altogether are 48.

What is ratio?

Mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another.

The number of skaters who brought their own skates = 5

The number of skaters who rented their skates = 3

So, the ratio is 5:3.

The number of skaters who brought their own skates = 12

Now equating to get the number of total skaters -

12 x (5+3) / (5-3)

= 96 / 2

= 48

Answers

The perimeter of the larger rectangle found using the scale factor of 4/5 is 56.25 cm.

What is meant by the perimeter of a figure?

A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges.

Given,

the scale factor = 4/5

The perimeter of the smaller rectangle = 45 cm

We are asked to find the perimeter of the larger rectangle(x).

Here both the rectangle are similar figures.

So the scale factor is the ratio of their corresponding sides.

But since the perimeter of a rectangle is the sum of the length of its sides.

The scale factor is also the ratio of the perimeter of the smaller rectangle to the larger rectangle.

Perimeter of small rectangle/Perimeter of large rectangle = 4/5

45/x = 4/5

x = 45 * 5 / 4 = 56.25cm

Therefore the perimeter of the larger rectangle found using the scale factor of 4/5 is 56.25 cm.

John and Scott are selling cheesecakes for a school fundraiser. customers can buy new york style cheesecake and so apple cheesecake. John sold 7 new york style cheesecakes and 4 apple cheesecake for a total of $116. Scott sold 8 new York style cheesecake and 12 apple cheesecakes for the total of$244. Find the cost of each of one New York style cheesecake and one apple cheesecake.

Answers

Let

x

represent the

price of one New York style

cheesecake

and

y

the price of

one apple cheesecake

. Based on the information provided, we can construct two equations:

7x + 4y= 116

8x + 12y = 244

We can

solve

for

x

in terms of

y

using the first equation:

7x= 116-4y\sx= (116-4y) / 7

When we plug this expression into the

second equation

for

x

, we get:

8[(116 - 4y) / 7] + 12y = 244

To

eliminate

the fraction,

multiply both sides by 7

.

8(116 - 4y) + 84y = 1708

Extending the parentheses and combining similar terms yields:

928-32y + 84y= 1708

When we simplify, we get the following:

52y = 780

When we

divide both sides by 52

, we get:

y = 15

We now know that

y = 15

; we can use either of the original equations to solve for x:

7x + 4(15) = 116

7x = 56

x = 8

Therefore, one

New York cheesecake costs $8

, and

one apple cheesecake costs $15

Answers

Given the transformations of the graph of f(x)=6x, the function rule g(x) is therefore g(x) = -1/2x.

What is transformation?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location. Transformations can be divided into four categories: translation, rotation, reflection, and enlargement. You must be able to carry out each transformation and recognize which ones have already been done.

Given Data

f(x) = 6x

The resulting function will be f(x) = -6x if the function is not reflected over the x-axis.

The final function rule will be; if the resulting function is compressed by a factor of 1/12.

g(x) = 1/12(-6x)

g(x) = -1/2x

Answers

Answer:

Step-by-step explanation:

If the seller made a profit of 20%, it means he sold the television at a price that is 20% higher than the cost price. That means that the sales price is 1.2 times higher than the cost price

let t = cost price of the television

the following equation can be derived

1.2 x t = $2700

divide both sides by 1.2

t = $2250

If there is a 10% discount, the television is (100 - 10%) 90% cheaper

how many ways can the letters of a word be arranged in a row if two letters must remain next to each other

Answers

To determine the number of ways that the letters of a word can be arranged in a row if two letters must remain next to each other, we can treat these two letters as a single unit. Therefore, the problem reduces to finding the number of ways to arrange this new "unit" and the remaining letters.

So, to answer the question directly, the number of ways that the letters of a word can be arranged in a row if two letters must remain next to each other is (n-1) x 2!
To solve this problem, we will treat the two letters that must remain next to each other as a single unit, and then find the total number of arrangements. Here's the step-by-step explanation:

1. Combine the two letters that must remain next to each other into a single unit. This will temporarily reduce the total number of items to arrange by one.

2. Count the total number of items (including the combined unit) that you need to arrange.

3. Calculate the factorial of the total number of items. This will give you a number of ways to arrange these items in a row.

4. Finally, since the two letters inside the combined unit can be arranged in two ways (either the first letter comes first or the second letter comes first), multiply the result from step 3 by 2.

By following these steps, you will get the total number of ways the letters of a word can be arranged in a row with the constraint that the two specified letters must remain next to each other.
