Answer:
options 1, 3, and 6.
Step-by-step explanation:
on the diagram, ∠2 is in the area of line EA and EG. If you are reading it by letters, ∠GEA is equal to ∠2 because they are in the same area. The last option (6) being ∠AEG, the middle angle is E which is the same as ∠GEA and ∠2.
hope this helps!! :))
Answer is A. first one...
P = -3
G = 3
P = -G = -(3) = -3
When a number has the |absolute value|, it refers to the amount of units the number is from 0. (you can think of a timeline)
|3| is 3 units away from zero
|-5| is 5. it is NOT -5 units from 0, since a number cannot be -5 units away.
Basically, these lines | x | will make the number positive.
answer
-5,-2, | -2 |, | 3 |, 8
Answer: 14/3
You need to multiply 3 x 4 then add the 2
Answer:
C) 65,535
Step-by-step explanation:
You can add up the 8 terms ...
3, 12, 48, 192, 768, 3072, 12288, 49152
to find their sum is 65535.
_____
<em>Estimating</em>
Knowing the last term (49152) allows you to make the correct choice, since the sum will be more than that and less than double that.
_____
<em>Using the formula</em>
You know the formula for the sum of a geometric sequence is ...
S = a1(r^n -1)/(r -1)
where a1 is the first term (3), r is the common ratio (4), and n is the number of terms (8).
Filling in the values, you find the sum is ...
S = 3(4^8 -1)/(4-1) = 4^8 -1 = 65535
