Answer 1

Answer:

We want to describe each one of the given functions as translations of a parent function.

The descriptions are:

1) This is a translation of 4 units to the left.

2) This is a translation of 4 units to the right.

3) This is a vertical translation of 2 units down.

4) This is a vertical translation of 2 units up.

First, we need to describe translations.

Horizontal translation.

For a given function f(x) a horizontal translation of N units is written as:

g(x) = f(x + N)

Where if N is positive the translation is to the left, if N is negative the translation is to the right.

Vertical translation.

For a given function f(x) a vertical translation is written as:

g(x) = f(x) + N

Where if N is positive the translation is upwards, and if N is negative the translation is downwards.

Now we have the parent function:

f(x) = √x

Then each one of the transformations can be described by knowing how the translations work:

1) y = √(x + 4) = f(x + 4)

This is a translation of 4 units to the left.

2) y = √(x - 4) = f(x - 4)

This is a translation of 4 units to the right.

3) y = √x - 2 = f(x) - 2

This is a vertical translation of 2 units down.

4) y =√x + 2 = f(x) + 2

This is a vertical translation of 2 units up.

Answer:

100

Step-by-step explanation:

0 = 400

1 = 350

2 = 300

Then,

3 = 250

4 = 200

5 = 150

Therefore, 6 will be 100

This stainless-steel fittingmeasures 3.9 cm long. It
has an inner diameter of
2.7 cm and an outer
diameter of 3.6 cm. If the
density of stainless-steel
is 8 g/cm3, what is the
mass of the fitting?

Answers

Subtract the volume of the inside diameter from the volume of the outside diameter and then multiply that by the density.

Volume of outside:

PI x 1.8^2 x 3.9 = 39.67704 cubic cm

Volume of inside:

PI x 1.35^2 x 3.9 = 22.318335 cubic cm

Difference: 39.67704 - 22.318335 = 17.358705 cubic cm.

Mass = 17.358705 x 8 = 138.86964 grams. Round the answer as needed.

Answers

The expression has a value that is 6 times the value of the expression 63 – 3y would be, 6 × (63 - 3y)

The correct answer is option (D)

What is an Expression?

"An expression is a sentence with a minimum of two numbers and at least one mathematical operation in it."

For given example,

We need to find the value that is 6 times the expression 63 – 3y.

If we write it as an expression then it would be,

6 × (63 - 3y)

An airplane flight has 228 seats. The probability that a person who buys a ticket actually goes on that flight is about 95%. If the airline wants to fill all the seats on the flight, how many tickets should it sell?A. Show your work.

B. Should your answer be more than 228 or less? Explain.

Answers

there should be 240 tickets sold

I made a proportion by doing 228/95 and equaling it to x/100

x= the number of seats that needs to be sold

I crossed multiplied
and got
95x=228×100

228×100=22800

95x=22800

then I diveded both sides by 95 and got

x=240

hope this helps :)

Final answer:

The airline should sell 217 tickets to have a 95% probability that all seats will be filled.

Explanation:

To determine how many tickets the airline should sell, we need to find the number of tickets that corresponds to a 95% probability of a person actually going on the flight. We can think of this as finding the number of tickets that gives us a 95% confidence level.

We can use the formula for confidence interval to find the number of tickets:

Number of tickets = (Desired confidence level) × (Total number of seats)

Number of tickets = 0.95 × 228 = 216.6

Since we can't sell a fraction of a ticket, the airline should sell 217 tickets to have a 95% probability that all seats will be filled.
