Answer:
8.1×10^12
Step-by-step explanation:
6.75×1.2=8.1 and power should be added 6+6=12 and answer is 8.1×10^12
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:
x=49
Step-by-step explanation:
los 3 angulos del triangulo deben de sumar 180
76+55=131
180-131=49
76+55+49=180
The answer is 1 and 1/12 because you have to have a common denomonator.
Answer:
1/2
Step-by-step explanation:
if you find the LCD of the numbers, you will find that it is 8. Then, you divide both of them by 8 and you get 1/2
Hope this helped a bit :)
