Question

how to determine the min of an equation?

Answer 1

? an equation does not have a minimum. it has a solution perhaps

Answer 2

no it says determine the minimum

Answer 3

well let's see your *function

Answer 4

y=345.14t^2-1705.65t+42903.6 t= 0 represents 1999

Answer 5

take the first derivative and set it = 0

Answer 6

hu???

Answer 7

is this a calculus question?

Answer 8

no

Answer 9

minimum is the second coordinate of the vertex. first coordinate is
\[-\frac{b}{2a}\] but i'll be damned if i can compute it with these ridiculous decimals. use a calculator

Answer 10

so okay the only thing is to plug them in right

Answer 11

apparently it is
\[\frac{112643504187}{2761120}\]at t = 170565\/69028

Answer 12

i thought it was 1705.65/2(345.14)

Answer 13

is it not?

Answer 14

you're right cherry

Answer 15

dy/dx = 690.28t-1705.65
690.28t-1705.65 = 0
t=1705.65/690.28

Answer 16

dy/dt*
