How do I solve for the minimum and maximum of the function y=-1/2x^2 -5x+2
Sever21 [200]

Try this solution:

There are several ways to find the max or min of the given function:

1. to use derivative of the function. For more details see the attachment (3 basic steps); the coordinates of max-point are marked with green (-5; 14.5)

2. to use formulas. The given function is the standart function with common equation y=ax²+bx+c, it means the correspond formulas are (where a<0, the vertex of this function is its maximum):

X_0=-\frac{b}{2a} ; \ X_0=-\frac{-5}{2*(-\frac{1}{2})} =-5.

Y_0=-\frac{D}{4a}; \ Y_0=-\frac{25+4*2*0.5}{4*(-\frac{1}{2})} =14.5

Finally: point (-5;14.5) -  maximum of the given function.

3. to draw a graph.

A Subaru Outback and a Freightliner Cascadia truck leave an intersection at the same time. The Outback heads west at an average
Nadusha1986 [10]

Answer:

  • d = 83.22t

Step-by-step explanation:

<em>The lines form legs of a right triangle, so the distance between the cars is the hypotenuse</em>

<u>The lines at t hours are:</u>

  • 70t and 45t

<u>So the distance d is:</u>

  • d = √(70t)²+(45t)² = √4900t²+2025t² = √6925t² = 83.22t
  • d = 83.22t
