can anybody plzz helpme understand what domain ,funtions and range are?

Answers

The domain is all input values(otherwise known as all x-values on the x-axis) and the range is all possible output values( y-values, as shown on the y-axis). Functions are expressions involving 1 or more variables, in a function x-values are only allowed 1 y-value or else it isn’t considered a function.

The measure of an angle is 60.6°. What is the measure of its supplementary angle?

Answers

Answer:

119.4°

Step-by-step explanation:

The answer is 119.4° because supplementary means that the angles add to 180°, and since 180-60.6 is 119.4, that is the answer.  

Sorry if I'm wrong but I hope this helps!  Have a great day/night!

Answer:

119.4 and the little degree sign (119.4 degrees)

Step-by-step explanation:

Supplementary angles add up to equal 180 degrees.

180-60.6=119.4 degrees

PLEASE HELP ME!!!!!!!!!!!!!
Write an inequality for the sum of twice a number and 5 is at most 15. Use y as the variable.

Answers

Answer:

The answer to the problem is 5

Step-by-step explanation:

The sum of twice a number y and 5 is at most 15" can be translated mathematically into the following inequality:

2y + 5 ≤ 15 since the sum, 2y + 5, is at most 15 but could be less than 15.

To solve this inequality for n, proceed as follows:

First, subtract 5 from both sides of the inequality as you would in solving an equation:

2y + 5 - 5 ≤ 15 - 5

2y + 0 ≤ 10

2y ≤ 10

Now, to finally solve the inequality for the variable y, divide both sides of the inequality by 2 as you would in solving an equation:

(2y)/2 ≤ 10/2

(2/2)y ≤ 10/2

(1)y ≤ 5

n ≤ 5 which is all real number less than or equal to 5.

Test Values (y = -1/2, 0, 3, 5, and n = 7):

For y = -1/2:

2y + 5 ≤ 15

2(-1/2) + 5 ≤ 15

-1 + 5 ≤ 15

-4 ≤ 15 (TRUE)

For y = 0:

2y + 5 ≤ 15

2(0) + 5 ≤ 15

0 + 5 ≤ 15

5 ≤ 15 (TRUE)

For y = 3:

2y + 5 ≤ 15

2(3) + 5 ≤ 15

6 + 5 ≤ 15

11 ≤ 15 (TRUE)

For y = 5:

2y + 5 ≤ 15

2(5) + 5 ≤ 15

10 + 5 ≤ 15

15 ≤ 15 (TRUE)

For y = 7:

2y + 5 ≤ 15

2(7) + 5 ≤ 15

14 + 5 ≤ 15

19 ≤ 15 (FALSE)

Therefore, the possible values for y which will make the relevant inequality, 2n + 5 ≤ 15, a true statement are:

{y | y is a real number and y ≤ 5}

The answer for this problem is 5

Answer: 36.4 miles per gallon!

Step-by-step explanation: To get your answer....divide the y (miles driven) by x (gallons used). Each divided gives you the answer of 36.4 which is the constant of proportionality between the number of miles driven and the number of gallons used.

For example: 691.6 divided by 19= 36.4

                       1528.8 divided by 42=36.4

                        1638 divided by 45=36.4

Can you help me?

Answers

Answer:

= -5

Step-by-step explanation:

First you would use distributive property and multiply the 9 and 2 (18x) then 9 and 15 (135)
Now you have 18x+135=45 so you need to get X alone by using inverse operations and subtract 135-45 (90)
18x=90 now you divide 18 and 90 and your answer is x=5

solve the equation to find the missing leg of the right triangle

x2+0.5 squared=1.3 squared

Answers

Answer:

1.2

Step-by-step explanation:

x2 is the missing leg so the formula to find the missing leg to a right triangle is

c squared- b squared=a squared which in this case would be

1.3 ^2 - 0.5^2 = x^2  ( ^ means squared)

1.69 - 0.25 = x^2

[tex]\sqrt{x}[/tex]1.44 = 1.2

1.2 = missing leg

A tower 15m high casts a shadow 30m long. A nearby telephone pole casts a shadow 16m long. Find the height of the telephone pole. Plz show ur work, thx slatttttt

Answers

Answer:

8 feet.

Step-by-step explanation:

If we know the shadow (30 ft) of a tower (15 ft), we can use use the ratio

[tex]\frac{30}{15}=\frac{16}{x}[/tex] where 'x' is the height of the telephone pole. Cross multiply, and we get the equation [tex]240=30x[/tex]. The rest of the problem is pretty straightforward, we divide both sides by 30 to find x. In the end, you will find that the height of the telephone pole is 8 feet.

Hope this helped!

The answer should be 8 feet
