Find the minimum value of the function for the polygonal convex set determined by the given system of inequalities.
lutik1710 [3]

Answer:

Option b (4,1)

Step-by-step explanation:

The region given by the system of inequalities is shown in the graph. We must look within this region for the point that minimizes the objective function f(x, y) = 8x + 8y

The minimum points are found in the lower vertices of the region.

These vertices are found by equating the equations of the lines::

3x+2y=14\\-5x +5y=10

-------------------

x = 2\\y = 4

-8x + 3y = -29\\3x + 2y = 14

---------------------

x = 4\\y = 1

The lower vertices are:

(4, 1) (2, 4)

Now we substitute both points in the objective function to see which of them we get the lowest value of f(x, y)

f(4, 1) = 8(4) +8(1) = 40\\f(2, 4) = 8(2) + 8(4) = 48

Then the value that minimizes f(x, y) is (4,1).

Option b

Type the correct answer in each box. Use numerals instead of words.
VARVARA [1.3K]

Answer:

see explanation

Step-by-step explanation:

f(x) = - (x + 1)(x - 3)(x + 2)

to find the zeros let f(x) = 0 , that is

- (x + 1)(x - 3)(x + 2) = 0

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x - 3 = 0 ⇒ x = 3

x + 2 = 0 ⇒ x = - 2

the zeros are x = -1, 3 and x = - 2

to find the y- intercept let x = 0

f(0) = - (0 + 1)(0 - 3)(0 + 2) = - (1)(- 3)(2) = - (- 6) = 6

y- intercept is located at (0, 6 )

Greg throws a snowball hitting Kyle 3 out of 5 throws. If Greg makes 60 throws, how many times does he hit Kyle?

36 throws because you divide 60 by five and get 12 and then multiply 3 by 12 giving you 36, are you sure this is high school
