Does this help? If it doesn't i can try to explain more if you want.
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
1) First, solve one linear equation for y in terms of x .
2) Then substitute that expression for y in the other linear equation.
3)Solve this, and you have the x -coordinate of the intersection.
4)Then plug in x to either equation to find the corresponding y -coordinate.

Answer: $274.05
Step-by-step explanation
Ok so, use the formula I=Prt
Meaning principal, rate, and time.
First, turn the % into 100...
Or just move the decimal two times to the right.
= .0725
Next, turn 48 months into years. 12 ÷ 4 = 48.
= 4 years
And finally, multiply ♀
You can multiple them in the order of the formula.
945× 0.0725 × 4
Giving you the answer of, $274.05.
Hopefully this helps ♀
