Answer:
Answer is -759/5
Step-by-step explanation:
To find the sum of a finite geometric series, use the formula,
Sn= a1-a1r^n/ 1-r
where n is the number of terms, a1 is the first term and r is the common ratio .
common ratio = a2/a1
S8=3-3(-2/3)8 / 1-(-2/3)
S8 = 3-(-2)8/ 1+ 2/3
S8= 3-256/ 3+2/3
S8= -253/5/3
S8= -253*3/5
S8= -759/5
7.256 + 5.088 + 16.009 = 28.353
693.501 - 56.287 = 637.214
Answer:
D)
Step-by-step explanation:
Answer:
-x^2 - 3
Step-by-step explanation:
SO we know f(x); x^2
when you place a (-), it flips teh image across the x-axis.
Finally, we see that the line is at (0,-3). To get it there, we need to go down 3, which gives us the -3 in the equation.
So we have -x^2-3
(rember the - sign is to flip it across the x-axis, and the -3 is to move the line 3 down the y-axis)
I checked my answer on a calculator btw lol.
