The explicit formula for the geometric sequence Negative one-ninth, one-third, negative 1, 3, negative 9, ellipsis is f (x) = ne

storchak [24]

Answer:

Common ratio, r=-3

Recursive Formula

$f(n)=-3f(n-1),$ $n\geq 2\\f(1)=-\dfrac{1}{9},$

Step-by-step explanation:

The formula for the geometric sequence: $-\dfrac{1}{9} ,\dfrac{1}{3}, -1,3,-9,\cdots$ is given as:

$f(x)=-\dfrac{1}{9}(-3)^{x-1}$

<u>Common Ratio</u>

Dividing the next terms by the previous terms, we obtain:

$\dfrac{1}{3} \div -\dfrac{1}{9} = \dfrac{1}{3} \times -9 =-3\\3 \div -1 =-3\\-9 \div 3 =-3$

Therefore, the common ratio of the sequence, r=-3

<u>Recursive Formula</u>

We observe that the next term, $f(n)$ is obtained by the multiplication of the previous term. f(n-1) by -3.

Therefore, a recursive formula for the sequence is:

$f(n)=-3f(n-1),$ $n\geq 2\\f(1)=-\dfrac{1}{9},$

Midpoint R(-4,6) and S(2,7)

shusha [124]

To find the midpoint, Add the two X coordinates together then divde by two and then to the same with the Y coordinates:

X = -4 + 2 = -2 / 2 = -1

Y = 6+7 = 13/2

Midpoint = (-1,13/2)

The cost of renting a car is $29.00 a day plus $0.25 for every kilometre after the first 100km. What is the cost of renting the

ira [324]

Answer:

$461

Step-by-step explanation:

First, find the cost with the daily charge of $29.

Multiply 14 by 29, since the car was rented for 14 days:

14(29)

= 406

Find the cost with the distance traveled. Since there is only a charge after the first 100 km, subtract 100 from 320.

320 - 100

= 220

Find the charge by multiplying this by 0.25:

220(0.25)

= 55

Add this to the daily charge:

55 + 406

= 461

So, the cost will be $461
