Answer:

greater than 7/8

Step-by-step explanation:

1 times 7/8 is 7/8 (no change).  7/8 = 0.875

5 times 7/8 is 35/8 (a lot greater than 7/8)

4.5 times 7/8 is 3.9375 (smaller than 7/8)

So again 5 times 7/8 will be greater than 7/8.

Find the maximum and minimum values of the objective function f(x, y) and for what values of x and y they occur, subject to the
Lady_Fox [76]

Given that <em>f(x, y)</em> is a linear function, and the constraints themselves are also linear, it follows that the vertices of the feasible region are the sites of extrema of <em>f(x, y)</em>. So just find where each boundary line intersects with another line, and check the value of <em>f(x, y)</em> at each intersection.

We have

• <em>x</em> = 0 and <em>y</em> = 0   ===>   (0, 0)

• <em>x</em> = 0 and 2<em>x</em> + 7<em>y</em> = 70   ===>   <em>y</em> = 10   ===>   (0, 10)

• <em>y</em> = 0 and 8<em>x</em> + 4<em>y</em> = 136   ===>   <em>x</em> = 17   ===>   (17, 0)

• 2<em>x</em> + 7<em>y</em> = 70 and 8<em>x</em> + 4<em>y</em> = 136   ===>   (14, 6)

At these points, we respectively get

• <em>f</em> (0, 0) = 0

• <em>f</em> (0, 10) = 60

• <em>f</em> (17, 0) = 34

• <em>f</em> (14, 6) = 64

Then max <em>f(x)</em> = 64 at (14, 6) and min <em>f(x)</em> = 0 at (0, 0).

Find a polynomial f(x) of degree 3 with real coefficents and following zeros. -4,4i
ElenaW [278]

Answer:

f(x)=x^3 +4x^2 +16x +64

Step by step explanation:

\text{Given that,  two roots are}~ -4~ \text{and}~  4i.\\\\\text{Let,}\\\\~~~~~~~x = 4i\\\\\implies  x^2 = 16i^2~~~~~~~;[\text{Square on both sides}]\\\\\implies x^2 = -16~~~~~~~~;[i^2 = -1]\\\\\implies x^2 +16 = 0\\\\\text{So,}~ x^2 +16~ \text{ is a factor of the 3 degree polynomial}.\\ \\ \text{The polynomial is ,}\\\\ f(x) = (x+4)(x^2 +16)\\\\~~~~~~~=x^3 +16x +4x^2 +64\\\\~~~~~~~=x^3 +4x^2 +16x +64
