Solve to three significant digits 123= 500e ^ -0.12x
Anon25 [30]
500{ e }^{ -0.12x }=123\\ \\ { e }^{ -\frac { 12 }{ 100 } x }=\frac { 123 }{ 500 } \\ \\ { e }^{ -\frac { 3 }{ 25 } x }=\frac { 123 }{ 500 }

\\ \\ { \left( { e }^{ x } \right)  }^{ -\frac { 3 }{ 25 }  }=\frac { 123 }{ 500 } \\ \\ { e }^{ x }={ \left( \frac { 123 }{ 500 }  \right)  }^{ \frac { 1 }{ -\frac { 3 }{ 25 }  }  }

\\ \\ { e }^{ x }={ \left( \frac { 123 }{ 500 }  \right)  }^{ -\frac { 25 }{ 3 }  }\\ \\ \ln { \left( { \left( \frac { 123 }{ 500 }  \right)  }^{ -\frac { 25 }{ 3 }  } \right)  } =x

\\ \\ x=-\frac { 25 }{ 3 } \ln { \left( \frac { 123 }{ 500 }  \right)  }

\therefore \quad x\approx 11.7

Graphing the function. h(x) = - 4 (show steps)
Archy [21]
Think about rise over run. Make the -4 a fraction into -4/1. Rise is the first, so you go down 4 pts down. Then run is 1, so you go 1 right. In this case, there is no beginning, so you begin at 0. The coordinates will be (0, 0) and (1, -4). You got the graph.

A company has an opportunity to bid on three contracts. Determine which would be the best investment given the information in th
MariettaO [177]

CONTRACT  PROFIT, (P)* OF PROFIT...(P)*. TO BREAK EVEN...LOSS, (P)* OF LOSS

Southeast $45,000,            50%                       30%                           $6,000, 20%

Southwest $60,000,            35%                      40%                          $10,000, 25%

California $112,000,           20%                       40%                          $40,000, 40%


I think that the best contract would be with SOUTHEAST. It probability of having a profit is higher than the other two at 50% while its probability of incurring a loss is lesser than the other two at 20%. 

Despite the bigger value of its contract profit of the other two, these value will still be greatly affected by its corresponding probabilities.

Ex 2.8<br> 3. find the maximum value of y for the curve y=x^5 -3 for -2≤x≤1
harkovskaia [24]
y=x^5-3\\ y'=5x^4\\\\ 5x^4=0\\ x=0\\ 0\in [-2,1]\\\\ y''=20x^3\\\\&#10;y''(0)=20\cdot0^3=0

The value of the second derivative for x=0 is neither positive nor negative, so you can't tell whether this point is a minimum or a maximum. You need to check the values of the first derivative around the point.
But the value of 5x^4 is always positive for x\in\mathbb{R}\setminus \{0\}. That means at x=0 there's neither minimum nor maximum.
The maximum must be then at either of the endpoints of the interval [-2,1].
The function y is increasing in its entire domain, so the maximum value is at the right endpoint of the interval.

y_{max}=y(1)=1^5-3=-2
