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
Answer:
Probably, 3/1.
Step-by-step explanation:
Just do the reverse of the instructions and you get your answer.
1+2=3
2-1=1
Answer:
A: 12x - 1.5
4(12x - 1.5)
B: 1st, 3rd, and 4th questions are correct.
Remember order of operations
PEMDAS which stands for
Parenthasees (or grouping symbols)
Exponents (square roots are also exponents, remmeber that)
Multiplication or Division, whichever comes first (remember, division is multiplication by a fraction
Addition or Subtraction, whichever comes first (subtraction is additon of a negative)
so
8-6*4+10/2=
no parenthases or exponents so multiply
-6*4=-24
we get
8-24+10/2
now divide
10/2=5
now we get
8-24+5
doesn't matter wha torder we do
-16+5
-11
