Answer:
tn = n·a
t10 = 10a
Step-by-step explanation:
We observe that the coefficient of 'a' is the term number:
tn = n·a

Hi.
To formally answer your question:
D. y = 0.75<em>x</em> + 11
We can prove this by substituting <em>x</em> with 1 (the initial measurement)
y = 0.75(1) + 11 = 11.75

That's vertex form for a parabola
and we read off vertex (p,q) as
Answer: Vertex (5,7)
The negative <em>a</em> tells us this is a downward opening parabola (upside down from the usual
. I remember CUP - Concave Up Positive; here <em>a </em>is negative so not a cup, instead concave <em>down.</em> The same rule applies to second derivatives in calculus so memorize it now and use it later.
Answer: downward
