Part (a)
Independent variable = age
Dependent variable = height
"depends on age" indicates that age is independent.
-----------------------------------
Part (b)
Independent variable = amount of sleep
Dependent variable = mood
The key word is "determines". The stuff before this word is the independent variable which affects the dependent variable.
-----------------------------------
Part (c)
Independent variable = time water has been running
dependent variable = amount of water in the tub
Time is usually the independent variable
-----------------------------------
Part (d)
Independent variable = speed
dependent variable = distance from home
-----------------------------------
Part (e)
Independent variable = amount of homework done
dependent variable = speed
This seems like an odd pairing of homework and speed. Could there be a typo? I noticed that part (f) is very similar
-----------------------------------
Part (f)
Independent variable = amount of hw that is assigned
dependent variable = amount of homework done
Like with part (a), the stuff before "depends" is the dependent variable
Answer:
The domain of f is {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]
Step-by-step explanation:
<em>The domain of a function is </em><em>all the values of x</em><em> make the function defined</em>
In the given graph
∵ The graph drawn from x = -7 to x = 7 and from y = -6 to y = 4
→ That means the values of x started from -7 and ended at x = 7
∵ The coordinates of the starting point of the graph of f are (-7, -5)
∵ The coordinates of the ending point of the graph of f are (7, 3)
∴ -7 ≤ x ≤ 7
∵ Values of x are the domain of the function
∴ The domain of the function is -7 ≤ x ≤ 7
∴ The domain of f = {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]
Answer:
its 14
Step-by-step explanation: i assumed 2 7 meant multiply sorry if wrong
2 1/2 + 2 3/5 =
2 5/10 + 2 6/10=
4 11/10 = 5 1/10
5 1/10 - 5 = 1/10
1/10 lb left over
6/8. if you add 1/8 and 1/8 you would get 1/4. so adding 2/8 to make one 1/4 we get 6/8 to make 3/4.
