Need help with linear systems

Lera25 [3.4K]

Answer:

The minimum value of C is 20

Step-by-step explanation:

we have

$2x+3y\geq 24$ ----> constraint 1

$4x+y\geq 38$ ----> constraint 2

$x\geq 0$ ----> constraint 3

$y\geq 0$ ----> constraint 4

using a graphing tool

The solution is the shaded area

see the attached figure

To find the minimum value of C evaluate the vertices (9,2) and (12,0) of the solution area in the objective function $C=2x+y$

For x=9, y=2 ---> $C=2(9)+2=20$

For x=12, y=0 ---> $C=2(12)+0=24$

therefore

The minimum value of C is 20

Write the equation of the circle that has a center of (-7, 17) with a radius of V19.

kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at (h,k) and radius r is given by ${\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}$ . Now , using same concept in this question ;

${:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}$

${:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}$

This is the required equation of Circle
