Answer:
sis 3rd option is correct
F'(x)=-2x{e^(-x²)}
Equating f'(x)=0,
i.e,
-2x{e^(-x²)}=0....eqn(i)
For maximum slope:
Differentiating (i) wrt x,we get,
4x² {e^(-x²)}-2 {e^(-x²)}=0
{e^(-x²)} [4x²-2]=0
4x²-2=0
x=1/√2
If f(x)=y then f'(x)=dy/dx=slope
So,
Maximum slope
= f'(x)
= -2x{e^(-x²)}
=-2×(1/✓2){e^(-1/✓2)²}
= -✓2{e^(-1/2)}
=(-sqrt 2/sqrt e)
=-sqrt(2/e)➡c is correct
ASA! The person above me is correct!
Answer:
Step-by-step explanation:
a =3 ;r = 1/2
first term = 3
second term = 3*1/2 = 3/2
third term = 3/2 * 1/2 = 3/4
Fourth term = 3/4*1/2 = 3/8
Fifth term = 3/8 * 1/2 = 3/16
GP is: 3,3/2,3/4,3/8,3/16......
