Question

9th grade algebra help!

Answer 1

i can try

Answer 2

3. The table below represents the displacement of a duck from its nest as a function of time.
Time (x) Displacement (y)
(hour) from nest ( Miles)
0 7
1 29
2 51
3 73
4 95

Part A: What is the y-intercept of the function and what does this tell you about the duck? (4 points)
Part B: Calculate the average rate of change of the function represented by the table between x=2 to x=4 hours? (4 points)
Part C: What would be the domain of the function if the duck continued to walk at this rate until it traveled 227 miles from the nest? ( 2 points)
Part A: What is the y-intercept?
What does this tell you about the duck?
Part B: What is the average rate of change from x = 2 to x = 4? Show your work.


Part C: Write a compound inequality of the domain if he traveled 227 miles from the nest?

Answer 3

forget it your on your own buddy :b nah just kidding give me a second

Answer 4

lol you scared me there a second haha

Answer 5

did they give you a graph to work with or no because this looks like something you need a graph for..

Answer 6

no that's all it

Answer 7

ok

Answer 8

well your y intercept looks like the Displacement, correct?

Answer 9

yes

Answer 10

ok so then your y intercept will be whats under the Displacement

Answer 11

ok

Answer 12

so what do you think these numbers infer to you about the duck?

Answer 13

I don't know

Answer 14

perhaps it tell you that he travels far?
-note- im not giving away answer just trying to see if you can figure this out

Answer 15

I've been stuck on this for almost a month, im trying my hardest lol

Answer 16

you waited a month to ask for help and isnt this due? :O

Answer 17

no she said before winter break we have to turn it in

Answer 18

oh ok brb i come back in like 3 minutes

Answer 19

ok

Answer 20

@Here_to_Help15

Answer 21

ok

Answer 22

@Here_to_Help15 help her real quick i gtg got to do a test

Answer 23

y-intercept is the y-value when x = 0. From the table, what is the y-value when x = 0?

Answer 24

what?

Answer 25

What is the answer?

Answer 26

It is 7

Answer 27

Ok? you got that

Answer 28

yeah

Answer 29

y-intercept = 7 What does this tell you about the duck? At time x = 0, the duck is 7 units away from the nest. That means the duck was NOT in its nest at time x = 0.

Answer 30

oh

Answer 31

Part B: What is the average rate of change from x = 2 to x = 4? Show your work. Average rate of change = y^2−y^1/x^2−x^1 Read the y-values from the table when x = 2 and when x = 4 Average rate of change = 95−51/4−2=?

Answer 32

dam thing wont let you put terms

Answer 33

hey I have to go anyways thankas a lot to both of you!

Answer 34

Part B: What is the average rate of change from x = 2 to x = 4? Show your work. Average rate of change = y^2 y^1/x^2 x^1 Read the y-values from the table when x = 2 and when x = 4 Average rate of change = 51/4

Answer 35

95-51/ 4-2

Answer 36

i meant

Answer 37

=?

Answer 38

44 / 2 = 22.

Answer 39

ok

Answer 40

C) Slope = 22 (same as average rate of change found in part B.) y = mx + b y = 22x + b when x = 0, y = 0 + b y = b From the table, when x = 0, y = 7. Therefore, b = 7 y = 22x + 7 Part C: Write a compound inequality of the domain if he traveled 227 miles from the nest? Set y = 227 in y = 22x + 7 227 = 22x + 7 227 - 7 = 22x 22x = 220 x = 10 Domain is x = 0 to x = 10. Or, domain is: [0, 10].

Answer 41

lol you type fast!

Answer 42

yea trying to hurry before you leave

Answer 43

lol thank you alot

Answer 44

Compound inequality for the domain: \[0 \le x \le 10\]
