Moira does one-half if a homework assignment on Monday. In Tuesday, Wednesday, and Thursday, she does one-half of the homework s
vichka [17]

On Monday, Moira doees 1/2 her homework. (1/2 remains)

On Tuesday, Moira does 1/2 of 1/2 = 1/4 of her homework. (1/4 remains)

On Wednesday, Moira does 1/2 of 1/4 = 1/8 of her homework. (1/8 remains)

On Thursday, Moira does 1/2 of 1/8 = 1/16 of her homework. (1/16 remains)

On Friday, she must do the remaining homework: 1/16 of the original amount.

Using exponents, the homework (hn) that Moira accomplishes on day n is

... hn = (1/2)^n

Since Moira does half each day, the amount left undone is equal to the amount done. The amount left undone on Thursday (for Friday) is equal to the amount done on Thursday:

... h4 = (1/2)^4 = 1/16

_____

Perhaps you're to sum the amounts done and subtract that from the total. That's going at it the long way around, but will get you the same result.

(Needed to be done on Friday) = 1 - ∑[n=1,4] (1/2)^n = 1 - (1/2)((1/2)^4-1)/(1/2 -1)

... = (1/2)^4 = 1/16

The sum of n terms of a geometric sequence is given by

S_n=a_1\cdot\dfrac{r^n-1}{r-1}\qquad\text{$a_1$=first term, r=common ratio}

Here, we have a_1 = 1/2 and r = 1/2. Then the sum of 4 terms is as shown above.

The cost for the olive oil used to fill the containers on the tables in an Italian restaurant is given by the function f(x) = 5x
Firlakuza [10]

If f(4a) = 80, then the value of "a" is 4.2

<em><u>Solution:</u></em>

Given that cost for the olive oil used to fill the containers on the tables in an Italian restaurant is given by the function:

f(x) = 5x – 4

where "x" represents the number of quarts of olive oil

f(x) represents the quarts of oil used

To find: value of "a" when f(4a) = 80

Substitute x = 4a in given function

f(4a) = 5(4a) - 4

80 = 20a - 4

20a = 84

10a = 42

a = 4.2

Thus the value of "a" is 4.2
