The larger the number is in front of the negative the smaller the number is. Fir example -90 is smaller than -5.
15 miles per hour is the correct answer. Did I help?
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
The symbol which appears before the number 2 is that of euro, a monetary unit used in some of the countries in Europe. The p is a symbol for peso. However, there are lots of pesos (e.g. Mexican, Philippine, etc). If we assume p there to be that of Philippine peso, the conversion would be,
80 p x (1 euro / 62.57 p) = 1.28 euro
Dividing the answer by 2, we get 0.64 or 4000/6257.
The answer is 1,002,257
I hope this helps!
