Answer: You need to grap a square where each side has 10 units in the grid.

Step-by-step explanation:

We know that each square has a side lenght of 0.1mm

Each unit in the grid represents 0.01mm

Then 10 units in the grid will represent 10*0.01 mm = 0.1mm.

Then the square face will be writen a square with a lenght of 10 units.

Will give brainliest, can somebody help me with this question
Andrew [12]

Answer:

A = 5x + 5

Step-by-step explanation:

Area of Parallelogram Formula: A = bh

Since we are given <em>b</em> = 5 and <em>h</em> = x + 1, simply plug it into the formula:

A = 5(x + 1)

A = 5x + 5

Answer:

The smallest model - bottom right - in the question diagram represents \sqrt[3]{64}=4.

Step-by-step explanation:

Considering the radical expression

\sqrt[3]{64}

Lets simply this radical expression first

As

\sqrt[3]{64}

\mathrm{Factor\:the\:number:\:}\:64=4^3

=\sqrt[3]{4^3}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a,\:\quad \:a\ge 0

\sqrt[3]{4^3}=4

      =4

Therefore, \sqrt[3]{64}=4

Now, as we can determine that \sqrt[3]{64}=4. So, the smallest model in the question diagram represents \sqrt[3]{64}=4 as each face of the cube of the smallest model in the diagram - bottom right - has 4 squares.

Therefore, the smallest model - bottom right - in the question diagram represents \sqrt[3]{64}=4.

(4) use the method of lagrange multipliers to determine the maximum value of f(x, y) = x a y b (the a and b are two fixed positi
wlad13 [49]
Assuming f(x,y)=x^ay^b. We have Lagrangian

L(x,y,\lambda)=x^ay^b+\lambda(x+y-1)

with partial derivatives (set to 0)[/tex]

L_x=ax^{a-1}y^b+\lambda=0\implies ax^{a-1}y^b=-\lambda
L_y=bx^ay^{b-1}+\lambda=0\implies bx^ay^{b-1}=-\lambda
L_\lambda=x+y-1=0

\implies ax^{a-1}y^b=bx^ay^{b-1}\implies -bx+ay=0
x+y-1=0\implies x+y=1

Solving this system of linear equations yields x=\dfrac a{a+b} and y=\dfrac b{a+b} as the sole critical point, which in turn gives a maximum value of f\left(\dfrac a{a+b},\dfrac b{a+b}\right)=\dfrac{a^ab^b}{(a+b)^{a+b}}.
