Ines has saved $5. She doubles the amount she saves each week. Does the function have a constant difference or a constant ratio? Does this represent an exponential function?

Answers

Answer 1

Answer:

The function have a constant ratio

No, it does not represent an exponential function.

Step-by-step explanation:

As given,

Ines has saved $5. She doubles the amount she saves each week.

⇒ In first week she saved = $5

   In second week she saved = 2×$5 = $10

   In third week she saved = 2×$10 = 20

  In fourth week she saved = 2×$20 = 40

and so on..

∴ we get the series

5, 10, 20, 40 ,.......

If the series is given as a, b, c, d, ..... , then

The common difference is defined as d = b-a = c-b

The common ration is defined as r = [tex]\frac{b}{a} = \frac{c}{b}[/tex]

Here, in the given question

The series is - 5, 10, 20, 40

This has no common difference , d =   10 - 5 (= 5 )≠ 20 - 10 (= 10)

As 5 ≠ 10

So the function does not define common difference .

Now,

This has common ratio , r =  [tex]\frac{10}{5} (=2) = \frac{20}{10}(=2)[/tex]

As 2 = 2

So, the function represent common ratio

Now,

The function does not represent an exponential function because it is increased by common ratio.

A quart of milk costs $1.89. What is the total cost for 20 quarts of milk?

Answers

To do this problem, you have to multiply the number of one quart of milk by twenty to get the total cost. So, you would do 1.89 x 20, which equals 37.8. So, the total cost would be $37.80 :)

(2t2 - 36t + 162). - (t-9)

Answers

Answer:

2t^2 - 37t + 171

Step-by-step explanation:

distrube the - to the (t-9) and then combine like terms

Answer:(2t2 +  27t) -  162  = 0  

STEP

2

:

Trying to factor by splitting the middle term

2.1     Factoring  2t2+27t-162  

The first term is,  2t2  its coefficient is  2 .

The middle term is,  +27t  its coefficient is  27 .

The last term, "the constant", is  -162  

Step-1 : Multiply the coefficient of the first term by the constant   2 • -162 = -324  

Step-2 : Find two factors of  -324  whose sum equals the coefficient of the middle term, which is   27 .

     -324    +    1    =    -323  

     -162    +    2    =    -160  

     -108    +    3    =    -105  

     -81    +    4    =    -77  

     -54    +    6    =    -48  

     -36    +    9    =    -27  

     -27    +    12    =    -15  

     -18    +    18    =    0  

     -12    +    27    =    15  

     -9    +    36    =    27    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -9  and  36  

                    2t2 - 9t + 36t - 162

Step-4 : Add up the first 2 terms, pulling out like factors :

                   t • (2t-9)

             Add up the last 2 terms, pulling out common factors :

                   18 • (2t-9)

Step-5 : Add up the four terms of step 4 :

                   (t+18)  •  (2t-9)

            Which is the desired factorization

Equation at the end of step

2

:

 (2t - 9) • (t + 18)  = 0  

STEP

Theory - Roots of a product

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.
