loris [4]

Step-by-step explanation:

  • Initial velocity (u) = 7 m/s
  • Final velocity (v) = 9 m/s
  • Time taken (t) = 2s

\dashrightarrow \quad \rm {a = \dfrac{v -u}{t} } \\

  • <em>a</em> denotes acceleration
  • <em>v</em> denotes final velocity
  • <em>u</em> denotes initial velocity
  • <em>t</em> denotes time

\dashrightarrow \quad \rm {a = \dfrac{9 -7}{2} \; m \: s^{-2}} \\

\dashrightarrow \quad \rm {a = \dfrac{2}{2} \; m \: s^{-2}} \\

\dashrightarrow \quad \underline{\boxed{\bf {a = 1 \; m \: s^{-2}}}} \\ (Answer)

Zinaida [17]
Well, if any number is higher than '5' it turns one number more. So, here's a good rhyme to help you: "Five or more, up the score, Four or less, let it rest." The maximum number it could be would have to be '444' because it is not bigger than 445, which would turn to 500.

Determine if the specified linear transformation is ​(a​) ​one-to-one and ​(b​) onto. Justify your answer. ​T: ​, ​T(​)​(​,​), ​
xz_007 [3.2K]

Answer:

C. T is not​ one-to-one because the standard matrix A has a free variable.

Step-by-step explanation:

Given

T(x_1,x_2,x_3) = (x_1-5x_2+4x_3,x_2 - 6x_3)

Required

Determine if it is linear or onto

Represent the above as a matrix.

T(x_1,x_2,x_3) = \left[\begin{array}{ccc}1&-5&4\\0&1&-6\\0&0&0\end{array}\right]  \left[\begin{array}{c}x_1&x_2&x_3\end{array}\right]

From the above matrix, we observe that the matrix does not have a pivot in every column.

This means that the column are not linearly independent, & it has a free variable and as such T is not one-on-one
