Answer:
7953.873
Step-by-step explanation:
The first derivative is ...
f'(x) = 4·3x²·e^x +4x³·e^x = e^x(4x³ +12x²)
Then the second derivative is ...
f''(x) = (12x² +24x)e^x +(4x³ +12x²)e^x
f''(x) = e^x(4x³ +24x² +24x)
So, f''(3) = (e^3)(4·27 +24·9 +24·3) = 396e^3 = 7953.87262158
Rounded to thousandths, this is ...
f''(3) = 7953.873
Answer:
95%
Step-by-step explanation:
95% *980 =931
(3/4)x+(3/2)x=9/4
(3/4)x+(3.2/2.2)x=9/4
(3/4)x+(6/4)x=9/4
3x+6x=9
9x=9
x=1
