Answer:

an = 3^(n-1)

Step-by-step explanation:

(1,1)  (2,3)  (3,9)

The y values

1,3,9,.....

We are multiplying by 3 each time

This is a geometric sequence

The formula for a geometric sequence is

an = a1 (r) ^ (n-1)

 where a1 is the first term  r is the common ratio ( or what we multiply by) and n is the term number

a1 = 1

r =3

an = 1* (3) ^ (n-1)

an = 3^(n-1)

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What
Ede4ka [16]

Answer:

None of these choices are correct.

Step-by-step explanation:

The quoted value of 99.875, means that this bond is sold at 99.875%  of the face value and not at a price of  $99.875.

Therefore, calculate price;

Price = 0.99875 * 1000

Price = $998.75

Since brokerage fees is 5.5% of the selling price, Leona will pay additional cost to the quoted price making the total cost to be more than $998.75;

Brokerage fees = (0.055*998.75) = $54.93

Total cost = $998.75 +$54.93

= $1053.68

Therefore, none of the choices is correct.

Mya is buying juice boxes for her party. Which offer should Mya choose to get the lowest price per juice box? 1.) 2 juice boxes
NemiM [27]

For this case we must find the unit cost of juice box of each option and compare:

Option A: 2 juice boxes for $ 0.66

\frac {0.66} {2} = 0.33 \frac {dollars} {box}

Option B: 6 juice boxes for $ 1.92

\frac {1.92} {6} = 0.32 \frac {dollars} {box}

Option C: 9 juice boxes for $ 2.97

\frac {2.97} {9} = 0.33 \frac {dollars} {box}

Option D: 12 juice boxes for $ 4.20

\frac {4.20} {12} = 0.35 \frac {dollars} {box}

The most feasible option is B. That is, buy 6 boxes for $1.92

Answer:

Option B

In 1997 there were 31 laptop computers at Grove High School. Starting in 1998 the school bought 20 more laptop computers at the
Kruka [31]

Using the linear equation, T = 20x + 31, the total number of computers at the end of 2005 is: C. 191.

<h3>How to Use a Linear Equation?</h3>

A linear equation is expressed as y = mx + b, where x is a function of y, m is the rate of change and b is the y-intercept or starting value.

In the scenario stated, we are given the linear equation for total number of laptop computers at the school after 1997 as, T = 20x + 31.

Rate of change = 20

y-intercept/starting value = 31

x = 2005 - 1997 = 8

To find the total number of laptop computers at Grove High School at the end of 2005 (T), substitute x = 8 into the equation, T = 20x + 31.

T = 20(8) + 31

T = 160 + 31

T = 191 computers.

Thus, total number of computers at the end of 2005 is: C. 191.
