an = a1r^(n-1)
a5 = a1 r^(5-1)
-6 =a1 r^4
a2 = a1 r^(2-1)
-48 = a1 r
divide
-6 =a1 r^4
---------------- yields 1/8 = r^3 take the cube root or each side
-48 = a1 r 1/2 = r
an = a1r^(n-1)
an = a1 (1/2)^ (n-1)
-48 = a1 (1/2) ^1
divide by 1/2
-96 = a1
an = -96 (1/2)^ (n-1)
the sum
Sn = a1[(r^n - 1/(r - 1)]
S18 = -96 [( (1/2) ^17 -1/ (1/2 -1)]
=-96 [ (1/2) ^ 17 -1 /-1/2]
= 192 * [-131071/131072]
approximately -192
Answer:Rocket Launch A toy rocket is launched straight up in the air from level ground. The distance (in ft) the rocket is above the ground (the position function) is <em>f (t) = 170t -16t2 at any time t (in sec) . Find </em>
Step-by-step explanation:
A dollar bill is worth 500 pennies. 1$ = 100 pennies.
<h2>Answer:</h2>
$0.32.
<h2>Explanation:</h2>
1 gallon = 128 fluid ounces.
So to find the price of an 8 ounce glass of Moo Milk we need to multiply (8/128) x 5.12.
That equals $0.32.
.09 times 6 is .54, I hope this helps
