Answer:
Step-by-step explanation:
A geometric series is one where each term is multiplied by a constant value known as r to get the next term
Sum of n terms of a geometric series is
Sum of infinite series is obtained as the limiting value of this sum when n tends to infinity
We find that only when |r|<1, r power n tends to 0 as n tends to infinity.
Other r power n diverges.
Hence geometric series infinite sum formula is valid only when
|r|<1 since the series sum converges to a finite value
Answer:
g = -0.5
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
Answer:
Step-by-step explanation:
Given in the data set as
26, 34, 38, 49, 65, 76, 81
Sum = 369
No of entries = 7
Mean =52.71
When 1213 is included
New sum = 1582
No of entries =8
New mean = 197.75
Thus mean increases by 145.04
7 hours 30 minutes = 7.5 hours
mph = distance covered in miles/ time taken in hours
mph = 375miles/7.5hours
Ans = 50mph (A)
we are given
x-intercept:
we can set f(x)=0
and then we can solve for x
we get
y-intercept:
we can set x=0 and find y
vertex:
now, we can find y-value
so, we get vertex as (1,5)
now, we can draw graph
