Determine whether multiplication by A is one to one linear transformation

Mathematics
1 answer:
lara [203]3 years ago
5 0
To know if the given matrix is one to one linear transformation, Row reduce the Matrix A and if it has free variables in it it means it is not a one to one linear transformation.

So, we take A and apply Row Operation and get the following matrix
 
1 0 0
0 1 0
0 0 0

As, it has free variables in it, it means it is not a one to one linear transformation.

Hope it helps :)

In a right angle,the altitude to a 6ft hypotenuse.Find the length of the altitude and each leg.
Nuetrik [128]

Answer:a=3.6 and b=4.8

Step-by-step explanation:(a^2)+(b^2)=(c^2)

Where c is hypotenuse is equal to 6. A right triangle is also known as a 3,4,5 triangle where the 2 legs are 3 and 4 and hypotenuse is 5. Find the factor in size difference by dividing your hypotenuse of 6 by the hypotenuse of 5 you get 1.2. Now multiply the 3 and 4 by 1 2 to get your answers of 3.6 and 4.8.

To check work simply plug in your legs as a and b

(3.6^2)+(4.8^2)=(6^2)

(12.96)+(23.04)=(36)

I can't find the answer to this anywhere so you'd be a huge help!
miv72 [106K]

Answer:

The answer would be d

Step-by-step explanation:

10^0 would be 0 because multiplying anything by 0 would result in 0 and 10^1 would be 10 and 10^2 would be 100 so adding them together would be 110. Hope this helped :)

Can someone solve this Im to lazy !
Sladkaya [172]
Not impressed that you consider yourself "too lazy" to at least get started on the solution of this problem.  Why not "give it the old college try?"

Start by  choosing letters to represent the unit cost of each popcorn and drink:
p:  popcorn, d:  drink.

Then 2p + 3d = $22.25 and 12p+4d=$39.00
Note that the unit of measurement of all 6 terms here is " $ ".

Solve this system of linear equations simultaneously:

2p + 3d = $22.25
12p+4d=$39.00

In your shoes I would mult. the first equation by -6 and then combine the result with the second equation.  p will temporarily disappear, and you'll be left with an equation in d only, enabling you to find the unit cost of a drink.

Come on.  Show your stuff.  You'll need to respond through Comments.

5) The graph of the parent linear function f(x) = x is shown in black on the coordinate grid. Write the function that represents
djyliett [7]

Answer:

(m) increased, (b) unchanged.     g(x)

(m) decreased, (b) unchanged.   m(x)

(m) unchanged, (b) increased.      h(x)

(m) unchanged, (b) decreased.    n(x)

f(x): m = -1/2  b = 2

g(x): m = 1/3  b = -3

h(x): m = 2  b = 0
