Help for number 4 part a and part b
djyliett [7]
Part A:  7/10 because .7 represents 70/100 of a whole, or 7/10.

Part B: I think 1 and 89/100 because 89/100 represents that fraction

These are my answers, so I may be wrong.

Hope I helped, and good luck!

What are the domain and range of the function f(x)=3x-1 /2
mel-nik [20]

Answer:

f(x)=3x−1

      2

Step-by-step explanation:

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:

(-∞,∞)

Set-Builder Notation:

{x|x∈R}

The range is the set of all valid

y

values. Use the graph to find the range.

Interval Notation:

(−∞,∞)

Set-Builder Notation:

{y|y∈R}

Determine the domain and range.

Domain:  

(−∞,∞),{x|∈R}

Range:

(−∞,∞),{y|y∈R}

How to derive: f(w)=ln(cos(w-1))
postnew [5]
The word you're looking for is "differentiate", not "derive".

\dfrac{\mathrm d}{\mathrm dw}\ln(\cos(w-1))=\dfrac{\frac{\mathrm d}{\mathrm dw}\cos(w-1)}{\cos(w-1)}=\dfrac{-\sin(w-1)\frac{\mathrm d}{\mathrm dw}(w-1)}{\cos(w-1)}=-\dfrac{\sin(w-1)}{\cos(w-1)}=-\tan(w-1)
