Answer:

Sequence 1: Translate 5 units to the right, and 5 units down

Sequence 2: Reflect across the origin, translate 1 unit down, 1 unit to the right

Step-by-step explanation:

Chose 1 point to focus in, such as (-1, 1)

Move that point 5 units to the right, and 5 units down. See how it matches up with the same corner of the red square?

Now, use that same point, and change the signs of both the x and y, this is to reflect across the origin. (In reality, you are just reflecting across the x and y axis)

So you originally have: (-1,1) -> (1, -1)

Now move this point one unit to the right, and 1 unit to the left.

It may seem that you made it touch the wring corner, but do the same thing with another corner's points. They all flipped!

The equation of the line perpendicular to line ab and passing through point c is 3y + x = 13.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

a is the point (-5,2),

b is the point (7,-2),

c is the point (-2,5),

the gradient of ab is 3.

The gradient of the line perpendicular to ab is, m = - 1 / 3

Calculate the equation of the line as shown below,

y - 5 = -1/3 [x-(-2)]

y - 5 = -1/3(x + 2)

3y - 5 × 3 = -x - 2

3y + x = -2 + 15

3y + x = 13

Therefore, the equation of the line perpendicular to line ab and passing through point c is 3y + x = 13.

The Sandbox must be 19x19 for the area to be 361.

Step-by-step explanation:

(19x19=361)

The length of the sandbox will be 19 feet.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the square in a two-dimensional plane is called the area of the square.

Given that Mr. Drew wants to build a square sandbox with an area of 361 square feet.

The length will be calculated by using the area formula for square;

Area of square = Length x width

Then the area of the square can be written as;

Area of square = ( Length )²

361=  ( Length )²

( Length ) = √361

( Length ) = 19feet

Therefore, the length of the sandbox will be 19feet.

Answer:

the slope is 5. 5/1

Step-by-step explanation:

Use rise over run to find slope. It is the easiest way to find slope

You rise 5 and 1 to the right

Answer:

The slope is 5

Step-by-step explanation:

So you're just trying to find the slop. We're going to choose 2 points to use which are already marked on the graph.

(0, 2) and (-1, -3)

So to find the slope, we have to find (the difference in y) / (the difference in x)

So we're going to do

-3-2/-1-0

Which is

-5/-1

So since there are two negatives, it become positive, and it'll simplify into 5.

The solutions to the equation 2cos(x) - 1 = 0.2cos(x) - 1 = 0 are given by x = cos^(-1)(5/9) + 2kπ, where k is an integer.

To solve the equation 2cos(x) - 1 = 0.2cos(x) - 1 = 0, we can simplify it as follows:

2cos(x) - 1 = 0.2cos(x) - 1

Subtracting 0.2cos(x) from both sides:

2cos(x) - 0.2cos(x) = 1

Combining like terms:

1.8cos(x) = 1

Now, we isolate cos(x) by dividing both sides by 1.8:

cos(x) = 1/1.8

cos(x) = 5/9

To find the solutions, we need to consider the values of cos(x) that satisfy the equation. Since cos(x) can take any value between -1 and 1, we can find the corresponding angles by taking the inverse cosine (cos^(-1)) of 5/9:

x = cos^(-1)(5/9) + 2kπ

where k is any integer, and π represents pi.

Therefore, the solutions of the equation 2cos(x) - 1 = 0.2cos(x) - 1 = 0 are given by:

x = cos^(-1)(5/9) + 2kπ, where k is any integer.

Note that the solutions are in the form of A + Bkπ, where A and B are constants derived from cos^(-1)(5/9), and k is an integer.

You can get 11 different numbers by multiplying two or more distinct members of the set (1, 2, 3, 5, and 11) together.

To find the number of numbers you can get by multiplying two or more distinct members of the set {1, 2, 3, 5, 11} together, we can use the concept of combinations. There are 5 elements in the set, and we want to choose 2 or more elements to multiply.

To choose 2 elements, there are 5C2 = 10 combinations.
To choose 3 elements, there are 5C3 = 10 combinations.
To choose 4 elements, there are 5C4 = 5 combinations.
To choose all 5 elements, there is 1 combination.

However, we need to subtract the cases where we multiply by 1, as 1 does not change the result.

For choosing 2 elements including 1, there are 4C1 = 4 combinations.
For choosing 3 elements including 1, there are 4C2 = 6 combinations.
For choosing 4 elements including 1, there are 4C3 = 4 combinations.
For choosing all 5 elements including 1, there is 1 combination.

Subtracting the cases with 1, we get:
(10 - 4) + (10 - 6) + (5 - 4) + (1 - 1) = 6 + 4 + 1 + 0 = 11 numbers.

So, you can get 11 different numbers by multiplying two or more distinct members of the set {1, 2, 3, 5, 11} together.

27 containers are needed to hold all the fuel from 12 tanks.

We are given that each tank holds 22.5 cubic yard of fuel, the weight of 1 yd³ (cubic yard) of fuel is equal to .74 tons, and each container holds 7.4 tons of fuel. Solving this problem would involve converting units.

In order to find out how many containers of the size are needed to hold all the fuel from 12 tanks, first we need to find how much fuel is delivered by 12 tanks. Since 12 x 22.5 = 270, 12 tanks are used to deliver 270 yd³ of fuel.

Next we convert it to tons. Recall that 1 yd³ of fuel is equal to .74 tons. Therefore, 270 yd³ = 270 x  .74 = 199.8 tons.

A container holds 7.4 tons of fuel. 199.8 ÷ 7.4 = 27, hence 27 containers are needed to hold all the fuel.

Answer:

Step-by-step explanation:

Given Ben's observations when the wait time is as advertised represented by the equation 2|x − 2| − 12 = 0, to get the times when the serving time is as advertised, relative to noon, we will calculate for the value of x in the equation;

Note that the modulus of the function |x-2| will return both positive and negative value.

For the positive value of |x-2|;

2|x − 2| − 12 = 0

2(x − 2) − 12 = 0

open the parenthesis

2x-4 - 12 = 0

2x - 16 = 0

add 16 to both sides

2x-16+16 = 0+16

2x = 16

x = 16/2

x = 8

For the negative value of |x-2|;

2|x − 2| − 12 = 0

-2(x − 2) − 12 = 0

open the parenthesis

-2x+4 - 12 = 0

-2x - 8 = 0

add 8 to both sides

-2x-8+8 = 0+8

-2x = 8

x = -8/2

x = -4

Hence the times when the serving time is as advertised, relative to noon are 8minutes and 4minutes

Answer:

Step-by-step explanation:

The probability of a person being randomly choosing having waiting time greater than 4.25 is 0.2917 or 29.17%.

To answer this question we need to know about-

Probability is the measure of the likelihood of an event to happen. The probability value ranges between 0 and 1.

When the probability value is 0, it means that the event is impossible to happen.

When the probability value is 1, it means that the event is certain to happen.

Uniform distribution is when the values of a probability distribution are spread uniformly across the interval, it is called a Uniform distribution

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 6 minutes.

The probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is found as follows:

Let X = Waiting time of a randomly selected passenger P(X > 4.25) = ?

Now we have to use the uniform distribution formula to find the probability:

P(C< X >D)=C-D/B-A

where C = lower value of the selected interval

           D= upper value of the selected interval

           B= highest value of the selected interval

           A= lowest value of the selected interval

putting above values in the formula -

P(X > 4.25) = 6 - 4.25/6-0= 0.2917

Hence the probability that a randomly selected passenger has a waiting time greater than 4.25 minutes is 0.2917.
