The sum of first 8 terms of series is -130208
<em><u>Solution:</u></em>
Given that,
2 - 10 + 50 - 250 , ....
n = 8
Find the common ratio between a term and its previous term
Thus common ratio is same
This is a geometric series
<em><u>The sum of terms of geometric sequence is given as:</u></em>
Where,
r is the common ratio
n is the nth term
is the first term of series
From series,
Therefore,
Thus sum of first 8 terms of series is -130208
Answer:
h = s / π.r²
Step-by-step explanation:
the given equation is s = π.r².h
Now if we have to calculate the value of h from the given formula then we will solve it so that h remains alone on one side of the equation.
This only possible when we divide term on both the sides by π.r²
s/π.r² = π.r².h/π.r²
h = s / π.r²
Therefore h = s / π.r² is the right option.
Its a dependent variable.
in independent variable is something being changed in an experiment to test the effects on the dependent variable. the dependent variable is what is being tested.
