For the given maximization problem there is  no the point in the feasible region which maximizes objective function C = 7x -3y.

A feasible region in any optimization problem is the collection of all the points where all the given constraints are satisfied.

For maximization problem, we will use the corner points of the feasible region and then we will check that on which corner point the objective function is maximum.

Given problem is:

Maximize Objective function C = 7x-3y

When the constraints are  (i) x≥0 , (ii) y≥0 , (iii) -x+5 ≤y

(iv) y ≤ (1/3)x +1

We will graph these constraints and  find the common shaded area.

x≥0,y≥0 represents that the point is in 1st quadrant

For -x+5 ≤y, we will use -x +5 =y

When x= 0 then y=5  and when y=0 then x=5 , then -x +5 =y is a line passing through (0,5) and (5,0)

and on putting (0,0) in -x+5 ≤y we get 5≤0 which is a false statement .

Therefore -x+5 ≤y is region starting with line -x +5 =y and going in direction to opposite to that of (0,0)

For y ≤ (1/3)x +1, we will use y = (1/3)x +1

When x= 0 then y=1  and when y=0 then x=-3 , then y= (1/3)x +1 is a line passing through (0,1) and (-3,0)

and on putting (0,0) in y ≤ (1/3)x +1 we get 0≤1 which is a true statement .

Therefore, y ≤ (1/3)x +1 is region starting with line y = (1/3)x +1 and going in direction of (0,0).

Thus we got the feasible region as shaded in the below attached figure.

The shaded area is unbounded , therefore no point of maximum exist on the feasible region.

Answer:

n = -4

Step-by-step explanation:

let the number = n

eight less than = .... minus 8

five times a number =n * 5

eight less than five times n = n * 5 minus 8 = n*5 -8

is means equal to

four more than = .... plus 4

eight times the number = n* 8

four more than eight times the number = n*8+4

n*5-8 is n*8 +4

n*5-8=8n+4

subtract 5n from both sides to put all variables and coefficients on one side

-8 = 3n + 4

subtract 4 from both sides to isolate the variable and coefficient

-12 = 3n

divide both sides by 3 to get n

n = -4

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

so a perpendicular line to that one will have

[tex](\stackrel{x_1}{3}~,~\stackrel{y_1}{2})\hspace{10em} \stackrel{slope}{m} ~=~ - 1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{- 1}(x-\stackrel{x_1}{3}) \\\\\\ y-2=-x+3\implies {\LARGE \begin{array}{llll} y=-x+5 \end{array}}[/tex]

The side length YZof a trapezoid WXYZ will be 2 cm.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.

The side lengths are given as:

JK = 12 cm

MJ = 6 cm

WX = 4 cm

WZ = n cm

From the diagram, the trapezoid JKLM is similar to the trapezoid WXYZ.

If the two polygons are similar then the ratio of the corresponding sides of the polygon is constant. The ratios are written as,

JK/WX = KL/XY = LM/YZ = MJ/ZW

JK/WX = MJ/ZW

The equations which is equivalent to 1 whole 1/2 x 3 whole 1/5 = 4 whole 1/2 is 3/2 x 16/5 = 9/2.

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now given equation is,

1 whole 1/2 x 3 whole 1/5 = 4 whole 1/2

Converting them into simple fraction we get,

1 whole 1/2 = 3/2

3 whole 1/5 = 16/5

4 whole 1/2 = 9/2

Thus, the equation becomes,

3/2 x 16/5 = 9/2

If f (0) = 1, then the point is ( 0 , 1 ) on the graph of f (x).

A point on a graph is represented by the form:

( x , y ) where x is the abscissa and y is the ordinate of the function.

We are given a point on the graph of f ( x ) = y as:

f ( 0 ) = 1

Comparing it with f (x) = y, we get that:

x = 0

y = 1

so, the point will become:

( 0 , 1 )

The steps given to find the standard deviation of the data-set are as follows:

For this problem, the are 5 values, hence:

n = 5.

The sum of the values is given by:

6 + 7 + 8 + 9 + 10 = 40.

Hence:

[tex]\sum x = 40[/tex]

The mean is given by:

40/5 = 8.

Hence:

[tex]\bar{x} = \frac{\sum x}{n} = 8[/tex]

The sum of the differences squared between each observation and the mean is:

(6 - 8)² + (7 - 8)² + (8 - 8)² + (9 - 8)² + (10 - 8)² = 10.

Hence:

[tex]\sum (x - \bar{x})^2 = 10[/tex]

Dividing by the number of values, we have that 10/5 = 2, hence:

[tex]\frac{\sum (x - \bar{x})^2}{n} = 2[/tex]

Taking the square root, the standard deviation is:

[tex]\sqrt{\frac{\sum (x - \bar{x})^2}{n}} = 2[/tex]

If 80 % (percentage) of marbles are blue then there are 36 blue marbles.

Percentage is the process of representing parts of a number by dividing the number into equal hundreds.

If the total amount is equivalent to 100 then the percentage denotes the number which is identical to the part of the number. In other words percentage denoted as % is part of 100.

The process of converting a part into percentage is by dividing the part by the total amount and multiplying the result by 100.

Now the total number of marbles in the jar is 45 and 80% of them are blue.

Now let us consider this :

so 80% of 45 = 80/100 × 45

or, blue marbles = 36
