400+0.1s
400 represents how much she earns per week
0.1 represents the percentage
s represents her weekly sales
0.1s represents how much of the weekly sales she gets to have.(I'm not sure if I worded the last one correctly.)
The answer is 9.5. Subtract 24 from 43 then divide by 2.
√50 + √242 - √2
= √5·5·2 + √11·11·2 -√2
= 5√2 + 11√2 - √2
= 16√2 - √2
= 15√2
Answer: a(n) = 5 - 3n
the sequence has:
a1 = 2
a2 = -1
a3 = -7
.........
we can see that: a2 - a1 = a3 - a2 = -3
=> the sequence is a arithmetic sequence
=> the distance between the numbers is d = -3
because this sequence is a arithmetic sequence
=> a(n) = a1 + (n - 1)d = 2 + (n - 1).(-3) = 5 - 3n
