Step-by-step explanation:
here, given points are
(-2,-1),(-5,-3),(-5,-4)
now
(X,y)________ (-y,X)
(-2,-1)________ (1,-2)
(-5,-3)________ (3,-5)
(-5,-4)________ (4,-5)
now plot the points in the graphs
<span>Unless you have some other choices, I'd have to say Stratification, to make sure the groups are representative and heterogeneous.
I hope I helped.</span>
The sum of first 20 terms of Arithmetic Series is 650 if the first term is 4 and the common difference is 3.
Step-by-step explanation:
First Term (a) = 4
Common difference (d) = 3
The number of term (n) = 20
The sum of an Arithmetic series of (n) number of terms, with first term (a) and the common difference (d) is equal to
Sum = (n/2) * ( 2 * a + (n -1) * d)
So putting the values of a,d, n
Sum = ( 20/2) * ( 2 * 4 + (20 -1) *3 )
Sum = (10) * ( 8 + 19 * 3)
Sum = 10 * ( 8 + 57)
Sum = 10 * 65 = 650
Hence the sum of first 20 terms of Arithmetic Series is 650 if the first term is 4 and the common difference is 3.
You need to divide this problem into two parts
first part is when it was accelerating.. that time use the equation of motion and calculate what is the total angle covered and hence you get the number of revolutions
then find the time of acceleration..so you ll understand for how much did you do the above calculation
for the rest of the time, the speed is constant (final angular speed).. so now you just use
w= theta/ time.. and get theta and again calculate the number of revolutions!
