2y^2 - y - 1 = 0
(2y + 1) (y - 1) = 0
2y + 1 = 0 or y - 1 = 0
y = -1/2 or y = 1
Answer:
That number is 0.45
Step-by-step explanation:
3/5x = 2x - 63/100
0.63 = 2x - 3/5x
0.63 = 10/5x - 3/5x
0.63 = 7/5x
7x = 0.63*5 = 3.15
x = 3.15/7

Then we will multiply both sides of the equation by 2 π :
x + π ( 1 - x ) = 0
x + π - π x = 0
x ( 1 - π ) = - π / · ( - 1 )
x ( π - 1 ) = π
x = π / ( π - 1 )
Answer:
the n(P) of P = {3, 5, 7, 11, 13, 17, 19} is "128".
Step-by-step explanation:
n(P) is the <u>Cardinality</u> of the set P. Its formula is 2^k.
where k = number of elements in the set.
