Answer:
Step-by-step explanation:
Given:
Linear transformation,
defined as
To Show: T is invertible
To find:
We know that Standard Basis of R² is
So, The matrix representation of T is
Now, Determinant of T = 1 - (-1) = 1 + 1 = 2 ≠ 0
⇒ Matrix Representation of T is Invertible matrix.
⇒ T is invertible Linear Transformation.
Hence Proved.
let,
Add (1) and (2),
Putting this value in (1),
Now,
Therefore,
Answer:
x>3
Step-by-step explanation:
You know the area, so you can use the area formula A = 1/2(a+b) (a and b being the parallel sides AB and CD)
So, set 32.5 = 1/2 (AB +CD)
substitute --> 32.5 = 1/2( x+(x+1) )
simplify --> 32.5 = (2x+1)/2
simplify again --> 65 = 2x +1 --> 64 =2x --> 32 =x
Now that you have x, you can substitute it into the formula for your height (x-1) to get 31
Answer:
18m I guess
Step-by-step explanation:
Answer: 6 days.
Step-by-step explanation:
Keep subtracting 2/3 from 4 until you have no gummy bears left. You woukd have to subtract 6 times to get to 0, so it would have to take 6 days.
