Answer:
A
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
- 12 ÷ - 3 = - 48 ÷ - 12 = - 192 ÷ - 48 = 4
this indicates the sequence is geometric with nth term
= a₁
where a₁ is the first term and r the common ratio
here a₁ = - 3 and r = 4 , then
a₈ = - 3 × = - 3 × 16,384 = - 49,152
210 degrees
Convert the problem from radians to degrees using the ratio 180/ and it will give you 210.
B. 88
the total data = 1+2+4+5 = 12
the median is (a6+a7) /2
a6 = 87, a7 = 89
so, the median = (87+89)/2 = 88
B
m(slope) = y2 - y1 / x2 - x1
-6 - - 6 / 7 - 3
= 0 / 4 = 0
