Answer:
The range is [10, ∞).
Step-by-step explanation:
This is the equation of a parabola which opens upwards and has a minimum value of 10 ( because of the + 10:- the vertex is at (5, 10).
For sake of convenience, reverse the series, then it would be:
21,19,17.....7
a=21, d = -2,
s(4) = 4/2 (21+15)
s(4)=2(36)
s(4) = 72
Answer:
Hey there!
The equation would be C=3.50r+5.75
Let me know if this helps :)
