Answer:
if I am not mistaken the answer should be
11.25C?
Step-by-step explanation:
I did like terms to add 3c to 3c plus 4c minus .75 which would equal 11.25 c if it were to ask for expression then 12c-.75
Woo-Jin and Kiran were asked to find an explicit formula for the sequence 64\,,\,16\,,\,4\,,\,1,...64,16,4,1,...64, comma, 16, c
olya-2409 [2.1K]
Answer:

Step-by-step explanation:
The given sequence is
64, 16, 4, 1



It is a geometric series because it has a common ratio
.
First term is 64.
The explicit formula of a geometric series is

where, a is first term and r is common ratio.
Substitute a=64 and r=1/4 in the above function.

Therefore, the required explicit formula is
.
Answer:
f(-1) = 8
Step-by-step explanation:
f(-1) = x
f(-1) = -5(-1) + 3
f(-1) = 8
1.) multiply the US dollars by the exchange rate $213 x 80.76 = 17,201.88
2. )divide pesos by the exchange rate 158/11.69 = $13.5158 so (a) is the correct answer
So the answer is
$13.52
(b)
A polynomial has the form

± 
+ ....
the only expression fitting this description is : x² + 2x + 7
