If you notice the terms, they're
7, -21, 63, -189 and so forth.
7*-3 = -21 and -21 * -3 is 63 and so forth, meaning the "common ratio" is -3.
now, for a common ratio say "r", which is a fraction, namely less than ±1 and more than 0, or |r| < 1 , you do have a convergent sequence.
however this one notice, |-3| is 3, and that's greater than 1 clearly, therefore is divergent, meaning the summation has no finite value.
Answer:
{x | x R, x ≤ 7 5/6 }
Step-by-step explanation:
we have
Convert mixed number to an improper fraction first
substitute
Multiply by 6 both sides to remove the fractions
Adds 38 both sides
Divide by 6 both sides
convert to mixed number
substitute
therefore
{x | x R, x ≤ 7 5/6 }
Answer:
Step-by-step explanation:
Negative 2/3 means -2/3
Hence;
1 + (-2/3) - (-m)
= 1 - 2/3 + m (positive x negative = negative, negative x negative = positive)
Substituting 9/2 for the value of m
= 1 - 2/3 + 9/2
The L.C.M = 6
= ( 6 - 4 + 27)/6
= 29/6
-4 ,0 and .3,0 and btw it’s second calc and 2 to find zeros on ur calculator
