Answer:
Decrease by 3.9%
Step-by-step explanation:
54,500(1-x) = 52355
x=0.03935... = 3.935% or 3.9%
-1/4 is not = -1 / 1/4 ( its = -4) so its neither .
1 + 5 = 6
3 + 3 = 6
3 + 47 = 50
7 + 43 = 50
13 + 37 = 50
19 + 31 = 50
Answer:
15
Step-by-step explanation:
5x + 2 = 77
5x = 77 - 2
5x = 75
5x/5 = 75/5
x = 15
Answer:
Y² = (1-X) / 2
Step-by-step explanation:
According To The Question, We Have
X= Cos2t & Y= Sint
the cartesian equation of the curve is given by Y² = (1-X) / 2 .
Proof, Put The Value of X & Y in Cartesian Equation, We get
Sin²t = {1-(1-2×Sin²t)} / 2 [∴ Cos2t = 1 - 2×Sin²t]
Taking R.H.S
- (1-1+2×Sin²t)/2
- 2Sin²t/2 ⇔ Sin²t = L.H.S (Hence Proved)
