To get your answer, you would divide your distance by your speed. You should be going about 1.4 miles per hour.
Answer:
18/100 or 9/50
Step-by-step explanation:
0.18 = 0.18/1
times 100 then 18/100
divided by 2 then 9/50
Answer:
A, B and D
Step-by-step explanation:
A. The polynomial is a trinomial.
A trinomial refers to a polynomial with three terms. This option is correct.
B. The degree of the polynomial is 6.
Degree refers to the highest power in the polynomial. This option is correct.
C. The leading coefficient is 1
This is false. The leading coefficient is the coefficient of the variable bearing the degree of the polynomial. This is wrong.
D. Written in standard form, the polynomial is –2x6 + x5 + 3.
This is correct.
Swapping rows alters the sign of the determinant:
![\begin{vmatrix} x & y & z \\ -8 & 2 & -12 \\ u & v & w \end{vmatrix} = - \begin{vmatrix} x & y & z \\ u & v & w \\ -8 & 2 & -12 \end{vmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bvmatrix%7D%20x%20%26%20y%20%26%20z%20%5C%5C%20-8%20%26%202%20%26%20-12%20%5C%5C%20u%20%26%20v%20%26%20w%20%5Cend%7Bvmatrix%7D%20%3D%20-%20%5Cbegin%7Bvmatrix%7D%20x%20%26%20y%20%26%20z%20%5C%5C%20u%20%26%20v%20%26%20w%20%5C%5C%20-8%20%26%202%20%26%20-12%20%5Cend%7Bvmatrix%7D)
Multiplying a single row by a scalar scales the determinant by the same amount:
![\begin{vmatrix} x & y & z \\ u & v & w \\ -8 & 2 & -12 \end{vmatrix} = -2 \begin{vmatrix} x & y & z \\ u & v & w \\ 4 & -1 & 6 \end{vmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bvmatrix%7D%20x%20%26%20y%20%26%20z%20%5C%5C%20u%20%26%20v%20%26%20w%20%5C%5C%20-8%20%26%202%20%26%20-12%20%5Cend%7Bvmatrix%7D%20%3D%20-2%20%5Cbegin%7Bvmatrix%7D%20x%20%26%20y%20%26%20z%20%5C%5C%20u%20%26%20v%20%26%20w%20%5C%5C%204%20%26%20-1%20%26%206%20%5Cend%7Bvmatrix%7D)
Then
![\begin{vmatrix} x & y & z \\ -8 & 2 & -12 \\ u & v & w \end{vmatrix} = -(-2) \begin{vmatrix} x & y & z \\ u & v & w \\ 4 & -1 & 6 \end{vmatrix} = 2\times(-6) = \boxed{-12}](https://tex.z-dn.net/?f=%5Cbegin%7Bvmatrix%7D%20x%20%26%20y%20%26%20z%20%5C%5C%20-8%20%26%202%20%26%20-12%20%5C%5C%20u%20%26%20v%20%26%20w%20%5Cend%7Bvmatrix%7D%20%3D%20-%28-2%29%20%5Cbegin%7Bvmatrix%7D%20x%20%26%20y%20%26%20z%20%5C%5C%20u%20%26%20v%20%26%20w%20%5C%5C%204%20%26%20-1%20%26%206%20%5Cend%7Bvmatrix%7D%20%3D%202%5Ctimes%28-6%29%20%3D%20%5Cboxed%7B-12%7D)
The answer to this question is D ( $0.18 ) per ounce:-)
