I need someone to help me today in math(I'm working on functions)
Ill be giving away points and brainliest all day
Here is the first one

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.

Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)

Answer 1

9514 1404 393

Answer:

  A. (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)

  B. is a function

  C. is a function

Step-by-step explanation:

Both relations are functions.

A relation is NOT a function if the same input value maps to two different output values. Virtually any relation involving time as an input will be single-valued: a measure can only have one value at any given time (ignoring quantum physics).

__

A: If height decreases 1/2 inch per hour, then some ordered pairs could be ...

  (hours, inches) = (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)

For each additional hour, 0.5 inches was subtracted from height.

__

B: There is only one output for each input, so the relation is a function.

__

C: Yes, the relation is still a function. There is still only one output value for each input value.

hiii umm yeah i need help on this its about direct variation equations

Answers

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

Whats is 7 = 12v - 24?

Answers

Answer:

To the nearest tenth: v = 2.6

To the nearest hundredth: v = 2.58

Fraction form = 31/12

Step-by-step explanation:

1. Add 24 to both sides to cancel it out on the right

7 = 12v - 24

+24          +24

2. Divide each side by 12

31 = 12v

31/12 = 2.5833333

12/12 = 1v = v

v = 2.583333

It’s V=31/12

(1). 7=12v-24 (12v is a variable so you move it left hand side and change its sign)

(2). 7-12v=-24 (7 is a constant so move it to the right hand side and change its sign)

(3). -12v=-24-7 (now calculate the difference -24-7)

(4). Now it’s -12v=-31, now after that divide both sides of the equation by -12

(5). So the answer is V=31/12

The perimeter of a triangle is 29 millimeters. The length of the first side
is twice the length of the second side. The length of the third side is
5 more than the length of the second side. Find the side lengths of the
triangle. Then classify the triangle by its side lengths.

Answers

Answer:

7.25, 3.625, 18.125

Scalene triangle

Step-by-step explanation:

Turn the lengths into a ratio:

First side twice as long as second side

Third side 5 times as long as second side

First side : Second side  : Third side = 2 : 1 : 5

2 + 1 + 5 = 8

29 / 8 = 3.625

Multiply the ratio by 3.625:

3.625 x 2 = 7.25

3.625 x 1 = 3.625

3.625 x 5 = 18.125

The sides so not follow Pythagoras's theorem a² + b² = c² (c being the largest side, so it is not a right angled triangle  so it is a scalene triangle

Answers

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

Diameter is a line that goes through a circle. Radius is a line that goes from the edge of the circle all the way to the center/a line that goes halfway through the circle.

--------------------------------------------------------------------------------------------------------------

First, find the area of the circle. Here is the formula:

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

Then, you just do the math:

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.
