What is an explicit formula for the geometric sequence -64,16,-4,1,... where the first term should be f(1).

nirvana33 [79]

Answer:

$a_{n} = -64(-\frac{1}{4})^{n-1}$

it seems like the first term is -64, so lets write the formula accordingly:

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

where 'n' is the number of terms

a1 is the first term of the sequence

'r' is the ratio

the ratio is $-\frac{1}{4}$ because -64 * $-\frac{1}{4}$ = 16 and so on...

the explicit formula is :

$a_{n}$ = $-64(-\frac{1}{4} )^{n-1}$

Jessica picked oranges for 2 days during school vacation. She was paid $0.45 per basket for the first 100 baskets picked each da

Mama L [17]

Answer:

$91.75

Step-by-step explanation:

Jessica is paid:

$0.45 per basket for the first 100 baskets picked;
$0.50 per basket for all baskets over 100 picked.

1st day:

Jessica picked 65 baskets of oranges (less than 100)

Jessica is paid $65\cdot \$0.45=\$29.25$

2nd day:

Jessica picked 135 baskets of oranges (35 more than 100)

Jessica is paid $100\cdot \$0.45+35\cdot \$0.50=\$45+\$17.50=\$62.50$

Altogether Jessica is paid

$\$29.25+\$62.50=\$91.75$
