Step-by-step explanation:
the answer should be 18
The area of a triangle is a+b+c
I think its (6.5+3.25)÷0.2=48.75
dont quote me on that, I tried and I'm not the best at math lol.
We are given
arithmetic sequence: u(1)= 124, u(2)= 117, u(3)= 110, u(4)=103
so, first term is 124
u(1)= 124
now, we can find common difference



now, we can find kth term

now, we can plug values
and we get



u(k) must be negative
so,


now, we can solve for k


so, it's closest integer value is
..............Answer
Answer:
Direct variation
Step-by-step explanation:
It's not iverse because the line is curved so it's direct variation
