Answer:
Option C) is correct
That is the given arithmetic sequence represents the recursive formula is f(n)=f(n-1)+(-5)
Step-by-step explanation:
The given arithmetic sequence is
Let f(1)=94,f(2)=89,f(3)=84,...
To find the common difference d :
,
Therefore d=-5
,
Therefore d=-5
Therefore the common difference d=-5
check the recursive formula which represents the given arithmetic sequence
Put n=2 and d=-5 in we get
Therefore f(2)=89
Put n=3 and d=-5 in we get
Therefore f(3)=84
and so on
Therefore the recursive formula where d=-5
Therefore the recursive formula represents the given arithmetic sequence
Answer:
25, 25/1, 4 5/5
Step-by-step explanation:
(190,258.50 + 152,698.00 + 122,753.00 + 220,523.00 + 231,951.00) : 5 = 183,636.70 - answer.
The average change in temperature from 9 a.m to 9 p.m is - 0.6 ° per hour (negative indicates temperature decreases), if the temperature at 9 a.m was 13.6 ° and the temperature at 9 p.m was 6.4 °.
Step-by-step explanation:
The given is,
The temperature at 9 a.m was 13.6 °
The temperature at 9 p.m was 6.4 °
The temperature at 3 a.m was 23.5 °
Step:1
Hours difference between 9 a.m to 9 p.m is,
= 12 hours (∵ consider a clock for this calculation)
Step:2
Temperature difference between 9 a.m to 9 p.m is,
= 6.4 - 13.6
= - 7.2 °
Step:3
Average change in temperature between 9 a.m to 9 p.m,
= - 0.6 ° ( ∵ Negative indicates temperature reduction)
Result:
The average change in temperature from 9 a.m to 9 p.m is - 0.6 ° per hour ( Negative indicates temperature reduction).
Answer:
$94.38
Step-by-step explanation:
find 20 percent of 78.65
78.65 * .2 = 15.73
(20% as a decimal is .20, or .2)
add the tip to the cost of the meal
78.65 + 15.73 = 94.38
total cost is $94.38
