Answer:
0.25
Step-by-step explanation:
Let the side of the square base be x, and the height of the box be h.
<span>The material of the base is x^2, and the material of the four sides is 4xh. </span>
<span>4000 = hx^2 </span>
<span>h = 4000/x^2 </span>
<span>The total material is </span>
<span>M = x^2 + 4x(4000/x^2) = x^2 + 16000/x </span>
<span>Take the first derivative of M and set equal to 0. </span>
<span>M' = 2x - 16000/x^2 = 0 </span>
<span>Multiply by x^2: </span>
<span>2x^3 = 16000 </span>
<span>x^3 = 8000 </span>
<span>x = 20; h = 10; M = 1200</span>
Answer:
Based on the graph below, what is the total number of solutions to the equation f(x)= g(x) will be 3.
Step-by-step explanation:
The intersection points of both graphs would be the total number of solutions to the equation f(x)= g(x).
From the given diagram, it is clear that both the graphs intersect at three locations points or intersection points. The approximations locations of The intersection points of both graphs are
Therefore, based on the graph below, what is the total number of solutions to the equation f(x)= g(x) will be 3.
Answer:
25
Step-by-step explanation:
maybe this will help you
A+b=-3, a=-3-b
ab=-35, and using a from above we get:
(-3-b)b=-35
-3b-b^2=-35
b^2+3b-35=0
b≈-7.6033 and 4.6033
So the two numbers are approximately -7.6033 and 4.6033
