Step-by-step explanation:

If you look carefully at the diagram, it looks like the French have no way out. The Prussians are on the outside perimeter and can always get supplies into their position. Since they are completely surrounded, the French do not enjoy that luxury.

Furthermore (and I'm guessing here) the Prussians probably outnumbered the French. Now it is possible to get around that problem, but not terribly likely if the numbers are really lopsided.

Residuals are used to determine how the line of best fit relates to the data points

A residual value of -0.8 means, the point is 0.8 units above the line of best fit

The residual value is given as:

[tex]\mathbf{Residual = -0.8}[/tex]

When the residual value is less than 0 (i.e. negative), then the point is above the line of best fit.

So, the interpretation of a residual value of -0.8 is that, the point is 0.8 units above the line of best fit

Answer:

[tex]- \frac{5}{4}[/tex]

Step-by-step explanation:

Use the slope form:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

m = slope

Let:

[tex](x_1 , y_1) = (-2 , -8)\\(x_2 , y_2) = (-6 , -3)[/tex]

Plug in the corresponding numbers to the corresponding variables, and solve:

[tex]m = \frac{-3 - (-8)}{-6 - (-2)} = \frac{-3 + 8}{-6 + 2} = \frac{5}{-4} = -\frac{5}{4}[/tex]

[tex]- \frac{5}{4}[/tex] is your answer.

Answer:

Step-by-step explanation:

Let X be the initial price in March 2004.  

Let X'  be the price for March 2005.

Let X" be the price for June 2005.

March 2005:  The price was reduced by 20%.  Thus, X' = 0.8X

June 2005:  The price was reduced by 1/6 of the March 2005 price:  Thus,

    X" = X' - (1/6)X'

Substituting, we have X" = (0.8X) - (1/6)(0.8X)

X" = (0.8X) - (1/6)(0.8X)

X" = (0.8X) - (0.1333X)

X" = 0.6667X

The June 2005 price is 0.6667 of the 2004 price.  That's a (1-0.6667) or 33.33% reduction.

Answer:

[tex]\sqrt{246}[/tex]

Step-by-step explanation:

The scale factor is [tex]\frac{4\sqrt{138} }{\sqrt{138}}[/tex] = 4

If AB = 6[tex]\sqrt{3}[/tex] then AC = 24[tex]\sqrt{3}[/tex]   4 times longer.

Using a² + b² = c²    substitute a = 4[tex]\sqrt{138}[/tex], b = 24[tex]\sqrt{3}[/tex], and c = DC = x

         [tex](4\sqrt{138})^2 + (24\sqrt{3} )^2= x^2[/tex]

            2208 + 1728 = x²

                3936 = x²

                 [tex]\sqrt{3936} = x[/tex]

                 4[tex]\sqrt{246[/tex]    this is the length of DC  

Now the length of EC is 4 times shorter, so EC = [tex]\sqrt{246}[/tex]

The inequality that represents the numbers of large, x and small, y boxes of a 200 pound delivery person is; 75x + 40y ≤ 200

Weight of large boxes = 75 pounds

Weight of small boxes = 40 pounds

Number of large boxes = x

Number of small boxes = y

Thus;

Total weight of large boxes = 75x

Total weight of small boxes = 40y

If the delivery man has 200 pound weight to deliver, then inequality is;

75x + 40y ≤ 200

Given the function [tex]f(x)=8^x+7[/tex], the value of f(1) is f(1)  =  15

The given function is:

[tex]f(x)=8^x+7[/tex]

To find f(1), substitute x = 1 into f(x) and evaluate for the result

[tex]f(1)=8^1+7[/tex]

Simplify the resulting equation to get the final result

f(1)  =  8  +  7

f(1)   =  15

Therefore, given [tex]f(x)=8^x+7[/tex], the value of f(1) is f(1)  =  15

Answer:

a= -1

b= 7

c= 0

Step-by-step explanation:

equation is

y=h(x)(x-7)

let x be 5 and y be 10 to solve for a

10=h(5)(5-7)

10=h(-10)

h=-1

now equation is

y= -x²+7x

so a=-1

b=7

c=0

The value of a is -1, the value of b is 7 and the value of c will be equal to zero.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both.

Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the data provided in the question,

y = h(x) × (x-7)

let x be 5 and y be 10 to solve for a

10=h(5) × (5-7)

10 = h(-10)

h = -1

now equation is

y = -x²+7x

So,

a = -1

b = 7

c = 0
