Answer:
Option 4 is correct.
Step-by-step explanation
Here the first term is 8 so the first term is given by f(1) = 8
Since here the given series is arithmetic series and here common difference is given by 5-8 = -3
Recurrence relation is given by f(n+1) - f(n) = d
where d is common difference which is given to be -3 .
therefore it is given as
f(n+1) -f(n) = -3
f(n+1) = f(n) -3 [ adding f(n) both sides]
Since n is starting from 1 there for its fourth option is correct
f(1) =8 and , f(n+1) = f(n) -3 ) , for n ≥1
Answer:
2 hours and 20 minutes
Step-by-step explanation:
1/3 of an hour is 20 minutes and a week is 7 days. Multiply 20 minutes by 7 days. You get 140 minutes which equals 2 hours 20 minutes
Let the common ratio be r.
then
a2*r*r=a4
rearrange,
r^2=a4/a2=112.5/50=2.25
r=sqrt(2.25)=1.5 = common ratio
Answer:
a. independent = number of days
dependent = number of miles
b. f(x)=340x
x = number of days
f(x) = number of miles
c. f(x)=850
850 miles
Step-by-step explanation:
a. the number of miles depends on number of days because more days equals more miles traveled.
b. Idk u need y or f(x) but just switch to one u need.
c. 340 × 2.5 = 850
Hope this helps!
The same reason 6 is more than 5, but less than 7. Since they are all divided by 8, the order still works.
