If these quadratic equations are written in
standard form, in which is it true that a = 1,
b = 2, and c = 3?
A. 2x + x² = 3
B. 3 + 2x = -x?
C. 2x = 3 + x2
D. 1 + 2x + 3x2 = 0

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

total of apples - take away four

6-4 = 2

answer is 2 apples

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

the answer would be a 24

c=2πr=2·π·3=24
