I believe x would just be 4? There isn’t much information given so that’s my best guess.

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

Find the sum of the first 20 terms of an arithmetic series if the first term is 4 and the common difference is 3.
Ratling [72]

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.

How should I attempt this question:
Anna35 [415]
 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!
