Do stain-polyurethane mixes protect wood as well as stain and polyurethane applied in separate coats? Five types of wood will be

used, with two boards of each type of wood. One board of each type of wood (randomly selected) will have the stain-polyurethane mix applied to it, and the other will have stain and polyurethane applied in separate coats. Each board will have water poured on it, and the amount of water retained will be measured. Which significance test is most appropriate

Answer:

The answer to your question is below

Step-by-step explanation:

5)                                2x² -7x + 34

                       x + 5   2x³ + 3x² - x + 1

                                 -2x³ -10x²

                                   0   - 7x² - x

                                        +7x² +35x

                                           0   +34x + 1

                                                 -34x - 170

                                                    0   - 160

Quotient = 2x² - 7x + 34

Remainder = -160

6)                                       2x² - 3x  + 1

                             3x + 1   6x³ - 7x² + 0x + 2

                                         -6x³ -2x²

                                          0    -9x² + 0x

                                                +9x² +3x

                                                   0   +3x + 2

                                                        - 3x - 1

                                                           0  + 1

Quotient = 2x² - 3x + 1

Remainder = 1

If y varies directly as x^2 and y=12 when x=2, find y when x=5
Shkiper50 [21]
y=ax^2\\\\y=12\ \ \ and\ \ \ x=2\ \ \ \Rightarrow\ \ \ 12=a\cdot 2^2\ \ \ \Rightarrow\ \ \ a= \frac{4}{12}= \frac{1}{3}  \\\\y=\frac{1}{3} x^2\\\\x=5\ \ \ \Rightarrow\ \ \ y=\frac{1}{3} \cdot5^2=\frac{25}{3} =8\frac{1}{3}

Name the coordinates of point K after its is reflected over the y-axis
Lena [83]

Answer:

(-3,6)

Step-by-step explanation:

When you flip or reflect over the y axis, the x value changes in the original ordered pair, but the y value stays the same

so the original ordered pair is (3,6) so the reflected ordered pair would be (-3,6)

Let the integers be x and x + 1

=> x + x + 1 = 85

=> 2x + 1 = 85

=> 2x = 84

=> x = 84/2

=> x = 41
