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:

  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.

To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.

From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.

Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.

Hope this helped!

She can expect to hit the bullseye 5 times.

Answer:

A. 5

Step-by-step explanation:

Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.

Answer:

r= 16.65

Step-by-step explanation:

Formula of cone V= 1/3 pi r ^2 h

They give us the volume and height, we just need to find the radius.

85= 1/3 pi r^2 9

1/3 of 9 is 3.

85= 3 pi r^2

divide by 3 on both sides.

28.3= pi r^2

square both sides with calculator or logic and round to nearest tenth.

5.3= pi r

divide pi.

r= 5.3 pi = 16.65

To find volume, plug everything in the formula.

Step-by-step explanation:

If you want the "exact circumference," use π instead of the usual approximation 3.14 or 3.14159.

Here the circumference is C = 2π(10 cm), or C = 20π cm.

The exact circumference is 62.83 cm.

If f(x) = 42 - 5 and g(x) = 3x+ 7, which of the following statements are true?

I f(0) = g(-4)
II f(-2) - 9(2)
III f(0) = g(3)
IV f(6) - g(4)

Α. I only
B. I and IV only
C. II and III only
D. All are true

Answers

Answer:

B. I and IV only

Step-by-step explanation:

You replace the x with the numbers in the parenthesis. So for I it would be:

f(0) = 4(0) - 5  -> 0 - (-5)  -> -5

g(-4) = 3(-4) +7 -> -12 + 7  -> -5

You solve each one and if your answer matches with each other, your answer is right.

If you did this with II and III, you wouldn't get the same answers.

For IV it would be:

f(6) = 4(6) - 5  -> 24 - 5  -> 19

g(4) = 3(4) + 7  -> 12 + 7  -> 19

Your final answer would be b 1 and 4

Part B: What are the initial value and slope of the graph and what do they represent?

Answers

Step-by-step explanation:The slope of AB and BC are the same.

The initial value is 60 m and the slope is 40 m/min.

Step-by-step explanation:

The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.

See the graph attached.

Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.

Now, those two triangles are similar and hence the slope of line segment AB will be .

Again, the slope of the line segment BC will be

Hence,  and the slope of AB and BC are the same. (Answer)

Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.

The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min. (Answer)
