Answer:

5. A= pi r^{2}                             r=radius              d=diameter

   C= pi 2r/ d

   A= pi 6^{2}

   A= 36pi

_____________________

    C=pi 2(6)/12

    C=12pi

____________________________________________________________

6. A=pi 4^{2}

   A=16pi

_____________________

  C=pi 2(4)/8

List the independent and dependent variables for each situation:
natulia [17]
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

what are the domain and range of f(x) = 4x – 8? domain: {x | x is a real number}; range: {y | y &gt; –8} domain: {x | x is a rea
Serga [27]

Answer : domain: {x | x is a real number}; range: {y | y >- 8}

the domain and range of f(x) = 4^x – 8

For exponential function , there is no restriction for x

So domain is all real numbers

For exponential function , f(x) = a^x + b

The range is y > b

The range of f(x) = 4^x -8 is y> -8

domain: {x | x is a real number}; range: {y | y > –8}
