Answer: 1 and 4
Step-by-step explanation: i dived them
Just use derivatives:
f'(x)= .48x-.96 = 0, x = 2, since the coeff of x^2 is +, this is a minimum
x=0 1989, so x = 2 is 1991! :)
The sum of the numbers is 7.69 * 10^6
<h3>How to evaluate the sum?</h3>
The expression is given as:
(1.54 times 10 superscript 6 baseline) (6.15 times 10 superscript 6 baseline)
Rewrite properly
(1.54 * 10^6) + (6.15 * 10^6)
Factor out 10^6
(1.54 + 6.15) * 10^6
Evaluate the sum
7.69 * 10^6
Hence, the sum of the numbers is 7.69 * 10^6
