ANSWER

The required equation is:

a_n=5(  - \frac{3}{5} )^{n-1}

EXPLANATION

The given sequence is

5, -3 ,  \frac{9}{5}

The first term of the sequence is ;

a_1=5

The common ratio is the subsequent term previous term of any two consecutive terms. This implies that;

r =  \frac{ - 3}{5}

The nth term of the sequence is

a_n=a_1(r)^{n-1}

We substitute the terms to obtain;

a_n=5(  - \frac{3}{5} )^{n-1}

Janes age is 5 years less than 3 times her brothers age. Janes age is 11 minus her brothers age. How old is Jane?
ANEK [815]

You did not specify the brother's age, so I make a expression, <em>b</em> as the variable.

(3<em>b</em> + 5) - 11

Now do that with the brother age instead of the variable.

The spending limit on John’s credit card is given by the function f(x)=15,000+1.5x , where x is his monthly income. f^-1x . The
Katena32 [7]
<span>1.
"The spending limit on John’s credit card is given by the function f(x)=15,000+1.5x"

means that if the monthly income of John is $ 5,000 ,he can spend at most 

f(5,000)=15,000+1.5*5,000=15,000+ 7,500=22, 500 (dollars)

Or for example

if Johns monthly income is $8,000, then he can spend at most

 </span>f(8,000)=15,000+1.5*8,000=15,000+ 12,000=27,000 (dollars)<span>


2.
Now, assume that the maximum amount that John can spend is y.

Then, y=15,000+1.5x

we can express x, the monthly income, in terms of y by isolating x:

</span>y=15,000+1.5x
<span>
1.5x = y-15,000


</span>x= \frac{y-15,000}{1.5}
<span>
thus, in functional notation, x, the monthly income, is a function , say g, of variable y, the max amount:

</span>x=g(y)=\frac{y-15,000}{1.5}

since we generally use the letter x for the variable of a function, we write g again as:

g(x)=\frac{x-15,000}{1.5}
<span>
for example :

</span>g(50,000)=\frac{50,000-15,000}{1.5}= \frac{35,000}{1.5}= 23,333
<span>
tells us that if the maximum amount that John can spend is 50,000 $, then his monthly income is 23,333 $.

3.

If John's limit is $60,000, his monthly income is 

</span>g(60,000)=\frac{60,000-15,000}{1.5}= \frac{45,000}{1.5}=30,000<span>
 dollars.


Answer: $ 30,000

Remark: g is called the inverse function of f, since it undoes what f does.

instead of g(x), we could use the notation </span>f ^{-1}(x)<span>
