Yes, you are correct.
Hope my answer helped u :)
Answer:
C
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
Here a₁ = 4 and r = - 3, thus
= 
=
= - (729 - 1) = - 728 → C
I’m pretty sure it’s 6 bc to calculate the volume it’s pie•radius^2
Answer:
1
Step-by-step explanation:
0=1-x
-1= -x
divide both sides by -1
x=1
Answer:
No solution
Step-by-step explanation:
x - 4y = 1 --> (1)
5x - 20y = 4 --> (2)
y = (¼)x - ¼ --> (1)
y = (¼)x - ⅕ --> (2)
Since these are 2 parallel lines with different y-intercepts, they will never meet
