Step-by-step explanation:
a1=ar⁰=12 A2=ar¹=-6
a=12 ar=-6
12r=-6
r=-6/12
r=-1/2
a10=ar⁹
=12*(-1/2)⁹
=12*(-512)
=-3/128
S∞ = a1 / (1-r )
=12/(1-1/2)
=12*1/2
=6
Answer:
Basically, you calculate your ratio and find what its is, but after that, you have to simplify it, giving you 4.
Step-by-step explanation:
The slope is 3/2. Because the equation is given in slope intercept for y=mx+c and m is slope
You would multiply the area by the height
Hope this helps
The answer is 2160
