The fact that she sold 5 of her books has no affect on the answer because she has already read the books. You just have to do the 21 books times the 2,010 words per book. This gives you 42,210 words. Hope this helps.

  a)

Let t represents number of years after 1900

so that means for 1900, value of t is 0

We are given point as (0,55)

and it says that life expectancy increases by 0.2

so that means slope,m=0.2

equation of line is y=mt +b

or y=0.2t +b

now we use point (0,55)

55 =0.2(0) +b

55 =0+b

55= b

so b=55

plug it back into the equation,we get

y=0.2t +55

b)

We are given y=73

so we plug it into the equation we got in part a and solve for t

y=0.2t +55

73 =0.2t +55

73-55 =0.2t

18 =0.2t

18/0.2 =t

90 =t

so t=90

This means the birth year =1900+t =1900+90 =1990

Option A: All real numbers is the right answer

Step-by-step explanation:

First of all, let us define domain

Domain is the set of all inputs to a function on which the function is defined

So

Given function is:

f(x) = 5.3^x

The given function will not be undefined for any value of x as there is no denominator which will make the function approach infinity

Hence,

Option A: All real numbers is the right answer

Keywords: Domain, functions
