Answer:
C
Step-by-step explanation:
The terms form a geometric sequence with common ratio r
r =
=
= ......
r =
=
= - 
The n th term formula of a geometric sequence is
= a
← a is the first term
here a = - 81, hence
f(x) = - 81
→ C
The answer to the question
Answer:
5x-5-3-1=-12
5x-9=-12
5x=-12+9
5x=-3
x=-3/5
Step-by-step explanation:
<span>a= 2 ft/s^2
t=3 s
vi=4 ft/s
vf=?
One can use the kinematic equation: vf=vi+at
vf=(4 ft/s)+(2 ft/s^2)(3 s)= (4 ft/s)+(6 ft/s)=10 ft/s</span>
If Jeremy has 2 cups of sugar, and evenly distributes it onto 9 cakes, he would have put .222 (repeating 2) cups of cake on each cake.
