Answer:
121.5
Step-by-step explanation:
Area is bases times height. The height is 4.5. And the bases is double the height. So 4.5 times 2 is 27. so we back to area wich is now 4.5 times 27 which is 121.5
<h2>A = b times h </h2><h2 /><h2>h times 2 = b </h2><h2 />
Answer:
a(n) = -81(-4/3)^(n - 1)
Step-by-step explanation:
The first term is -81. From -81 we obtain the next term, 108, by multiplying -81 by -4/3. Note how (-4/3)(108) = -144 as anticipated.
Thus, the common ratio is -4/3.
The explicit function for this geometric series is
a(n) = -81(-4/3)^(n - 1)
