Think your answer is $27,100.

Answer:

100-20=80

80+ 6.75 = 86.75

139/100 X 86.75 = 120.5825

$120.58

Area of a square = Side x Side (length x width)

A = 1.69 m²

Length = √area of square

L = √1.69 m²

L = 1.3 m

Check Work: 1.3² = 1.3 m x 1.3m

= 1.69 m²

Answer:

he needs 1.3 meters of laminate for the length

Step-by-step explanation:

area of a square = side multiplied by side (or length x width)

area = 1.69 m²

Length = √area of square

L = √1.69 m² or 1.3m

Are you good at surfing? Is it similar to skateboarding?

Answer:

Your answer will be x=2

Step-by-step explanation:

Five plus 6 times a number is equal to 21 minus 2 times the number

Your equation is this:

5+6x=21-2x

Subtract 6x from both sides

5+6x-6x=21-2x-6x

5=21-8x

subtract 21 on both sides

5-21=21-21-8x

-16=-8x    Divide -8 on both sides

2=x

If f(x) = x ⁴ - 2x ² + 3, compute the first and second derivatives:

f'(x) = 4x ³ - 4x

f''(x) = 12x ² - 4

Solve f'(x) = 0 to get the critical points of f(x) :

4x ³ - 4x = 4x (x ² - 1) = 0

→   x = -1, x = 0, x = 1

Check the sign of the second derivative at each of these points:

f'' (-1) = 8 > 0

f'' (0) = -4 < 0

f'' (1) = 8 > 0

These indicate the presence of

• two minima of f (-1) = 2 and f (1) = 2

• one maximum of f (0) = 3

which makes C the correct answer.

Answer:

y = -2

Step-by-step explanation:

You substitute 2 as x, y = 6 - 4 * 2, which is y = 6 - 8 = -2.

Answer:

to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Answer:

y

Answer:

i think 8/1000

Step-by-step explanation:

The fraction is 8/9.

Any number that can be expressed as a fraction and where the denominator (the bottom number) and the numerator (the top number) are both integers is considered a rational number.

We have the decimal is 0.8(bar).

let x= 0.888888....    (1)

Now, multiply above equation by 10

10x = 8.8888.....         (2)

Subtraction equation (1) and (2), we get

10x - x = 8.8888.... - 0.88888...

9x = 8

x = 8/9

Thus, the fraction is 8/9.

Answer:

The volume is [tex]10.648 \times10^{-18}[/tex] cm³

The scientific notation [tex]1.0648 \times10^{-17}[/tex] cm³.

Step-by-step explanation:

Consider the provided information.

The side of a cube measures [tex]2.2\times10^{-6}[/tex] cm.

The volume of cube = [tex]s^3[/tex]

Where, s is the side.

The volume of cube: [tex]V=(2.2\times10^{-6})^3[/tex] .

[tex]V=(2.2)^3 \times(10^{-6})^3[/tex]

[tex]V=10.648 \times10^{-18}[/tex]

Hence, the volume is [tex]10.648 \times10^{-18}[/tex] cm³

The scientific notation [tex]1.0648 \times10^{-17}[/tex] cm³.

Step-by-step explanation:

Calculation to Find two positive numbers

First step

Let the first positive number be a

Let the second positive number be b

Second step is to create the Equation

a^2+b= 54....... Equation (1)

b = 54-a^2........ Equation (2)

Third step is to find the product

Product= a(54-a)^2 = 54a-a^3

Fourth step is to differentiate

dP/dx = 54-3a^2

dP/dx = 0

Fifth step is to solve for 54-3a^2 = 0

Hence,

3a^2=54

a^2 = 18

Last step

a= √(18)

b= 54-(√(18))^2

b=54-18

b = 36

Therefore the two positive numbers are 36
