2. Which set below is the domain of
{(2, -3), (-1,0), (0, 4), (-1, 5), (4, -2)}?
F-3, 0, 4, 5, -2}
H {2, -1,4}
G-3, 4, 5, -2}
D {2, -1, 0, 4}

Answers

Answer 1

Answer:

D

Step-by-step explanation:

the domain is the interval or set of all valid x values.

the range is then the interval or set of all valid y values.

so, the x values are

2, -1, 0, -1, 4

and the set eliminates any multiple appearances of a value.

so, we get

{2, -1, 0, 4}

If it takes you 40 seconds to travel from the first floor of a building to the third floor, how long will it take to travel from the first floor to the eighth floor (at the same pace, assuming all floors have equal height)? State your answer in seconds.

Answers

Answer: 104 seconds.

Step-by-step explanation: if it takes you 40 seconds to travel from the first to the third floor, then to pass one floor it will take 13 seconds. 40 divided by 3 which is 13. you then do 13x8 to figure out the time it would take you to travel through all the floors which is 104 seconds.

40/3 = 13

13 x 8 = 104

The answer is 104.

Step-by-step explanation: You can only have a whole number of jars. If you divide options A, B, and C, you will get a number with a wild decimal. Option D is correct because 2,178 divided by 242 is 9, which does not have a wild decimal.

points A,B,and C are collinear. Point B is between A and C. AC= 3x+3, AB= -1+2x, and BC= 11. Find x

What is line segment?

It is a part of line having two ends points.

The simplest definition of a line is an arrangement of points that extends in opposite directions to infinity, while a ray is a section of a line that has one endpoint and extends continuously in one direction, while a segment of a line is a section of a line between two endpoints.

Here, it is given that points A,B and C are collinear that is all lies in the same plan and also :

Length of AC = 3x+3

Length of AB = -1+2x

and, BC = 11 units

Now, to calculate x we subtract length AB with AC and equate it to length of BC that is 11 units :

AB = AC + BC

-1+2x = 3x+3 + 11

3x-2x = -1 -3 - 11

x = -15 units

Therefore, the value of x is -15 units when AC= 3x+3, AB= -1+2x, and BC= 11.

Answers

When modeling hourly pay, the part of the equation used to represent the total pay is y ( Option C ).

The question asks when modeling hourly pay, which part of the equation is used to represent the total pay.

The given options are :

A. x

B. y-intercept

C. y

D. None of the above

This question can be easily solved using the slope intercept form of the line equation, that is, y = mx + c

where,

m is the slope of the line

and it represents the payment per hour

x is the independent variable

and it represents the number of hours

c is the intersection with the y axis

and it represents the signing bonus

y is the dependent variable

and it represents the total pay

From the above information, it can be inferred that when modeling hourly pay, the part of the equation used to represent the total pay is represented with y in the slope intercept form y = mx + c

Therefore, using the slope intercept form, we get the part of the equation used to represent the total pay as y ( Option C ), when modeling hourly pay.

Answers

It’s the C because i did it in virtual class science

The measure of the angle is 20.63 degrees if the lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively option (A) is correct.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

It is given that:

The lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively.

As we know,

Applying sin ratio

sinA = perpendicular/hypotenuse

sinA = 3.7/10.5

sinA = 0.35

sinA = 20.63 degrees

Thus, the measure of the angle is 20.63 degrees if the lengths of the hypotenuse and one leg of a right triangle are 10.5 and 3.7, respectively option (A) is correct.

Step 2: What amount of money does he intend to spend each month of these items together? Round your answer to the nearest dollar.

Answers

Travis's will spend each month is $2,408

How to calculate the amount Travis will spend each month ?

Travis income is $3400

He plans to budge 3/8 of his income on savings
He also plans to give 1/3 of the income on groceries

The amount spent on savings is

= 3/8 × 3400

= 3 × 425

= 1,275

The amount spent on groceries is

1/3 × 3400

= 3400/3

= 1,133.33

The amount spent altogether is

1,133.33 + 1,275

= 2,408.3

Hence the amount Travis spent from his income each month is $2,408

The true statements about the numbers are:

The two numbers could  be 180 and 36The two numbers could  be 10 and 4The two numbers could  be 8 and 5

How to determine the two numbers each individual thinks?

As a general rule, the product of any two numbers equals the product of the LCM and HCF of the numbers

Say, the two numbers are x and y;

Then, we have

x * y = LCM * HCF

Using the above as a guide, we have

Two numbers

x * y = 18 * 360

Express 360 as 10 * 36

x * y = 18 * 10 * 36

So, we have

x * y = 180 * 36

This means that

x = 180

y = 36

Hence, the two numbers could  be 180 and 36

Emily's numbers

x * y = 1 * 40

Express 40 as 10 * 4

x * y = 1 * 10 * 4

So, we have

x * y = 10 * 4

This means that

x = 10

y = 4

Hence, the two numbers could  be 10 and 4

Niamh's numbers

x * y = 8 * 5

Express 8 as 4 * 2

x * y = 4 * 2 * 5

So, we have

x * y = 8 * 5

This means that

x = 8

y = 5

Hence, the two numbers could  be 8 and 5
