A. 2,-2,2,-2,2,-2,2
C. 10,5,2.5,1.25,0.625,0.1325
and
D. 1,2,4,8,16,32
Are all geometric sequences
This means that each sequential # is derived by either multiplying or dividing by a number.
For instance, A. is found by multiplying each by - 1, B. is found by multiplying each by 1/2 (0.5), and D. is found by multiplying each by 2
Answer:
I and III only
Step-by-step explanation:
step 1
we know that
In this problem
A, B and C are collinear
so
A', B' and C' are collinear too
because the transformation is a translation
The translation does not modify the shape or length of the figure
AB=A'B'
AC=A'C'
BC=B'C'
step 2
The distance
AA'=BB'=CC'
because AB and A'B' are parallel
A perfect cube is a number that is a cube of an integer.
Break down the problem into these two equations;
x = -31
-x = -31
Solve for the 1st equation; x = -31
x = -31
Solve for the 2nd equation; -x = -31
x = 31
Collect all solutions
x = ±31
Check the solution
When x = -31, the original equation; |x| = -31 does not hold true. Thus, we will drop x = -31 from the solution set.
Check the solution again;
When x = 31, the original equation |x| = -31 does not hold true as well. Thus we will drop x = 31 from the solution set.
Therefore,
<u>No solution exists to this equation. </u>
