Identify the 12th term of a geometric sequence where a1 = 8 and a6 = −8,192.
vodka [1.7K]
Geometric sequence
a_{n}=a_{1}*r^{n-1}
r=common ratio
a1=first term
find r

a1=8
a6=-8192
-8192=a_{6}=8*r^{6-1}
-8192=8*r^{5}
divide both sides by 8
-1024=8*r^{5}
take 5th root of both sides
-4=r
sub
a_{12}=8*(-4)^{12-1}
a_{12}=8*(-4)^{11}
a_{12}=8*-4194304
a_{12}=-33554432

Xelga [282]

Somewhere you're given the equation for height as a function of time:

... h(t) = -16t² + v₀·t . . . . . . where v₀ is the initial vertical velocity in ft/s

For v₀ = 224, this becomes

... h(t) = -16t² + 224t

And this can be rewritten in vertex form as

... h(t) = -16(t² + 14t)

... h(t) = -16(t² + 14t +7²) +16·7² . . . . . complete the square (add the square of half the t coefficient inside parentheses; add the opposite of that amount outside parentheses)

... h(t) = -16(t +7)² + 784

The vertex of this downward-opening parabola is (7, 784), so ...

The rocket reaches its maximum height at 7 seconds.

The maximum height of the rocket is 784 feet.
