<u>QUESTION 1</u>
The given sequence is .
The first term of the sequence is
The second term is
The common ratio can be found using any two consecutive terms of the sequence.
Thus, the common ratio is given by .
This implies that,
This simplifies to,
The correct answer is C
<u>QUESTION 2</u>
The sum of the first n terms of a geometric sequence is given by;
.
Since we are looking for the first five terms, we substitute , and into the formula to obtain,
This will evaluate to give us;
The correct answer is A
<span>statements is not true
</span><span>D. -a = c

Answer:
Step-by-step explanation:
The midline is half the length of the parallel base.
2(2x +36) = 3x +57
4x +72 = 3x +57 . . . . . . eliminate parentheses
x = -15 . . . . . . . . . . subtract 72+3x from both sides
Then the length of GH is ...
GH = 2x +36 = 2(-15) +36 = -30 +36
GH = 6
_____
The calculation steps are shown above. The strategy is to take advantage of the relation between the lengths of a midline and the corresponding base segment.

Answer:
The correct option is 2. The best estimate for the price of the house in year 2018 is $407,000.
Step-by-step explanation:
The given equation is
Where p is the average sale price of house (in thousands of dollars) and t is number of years since 2010.
We have to find the best estimate for the price of the house in year 2018. The difference between 2018 and 2010 is 8 years.
Substitute t=8.
Therefore the estimate for the price of the house in year 2018 is 407 thousand dollars, i.e.,$407,000. Option 2 is correct.
