(1) Let T: Rn--->Rm be linear tranformations.

Mathematics
1 answer:
Ray Of Light [21]3 years ago
6 0

Answer:

Check the explanation

Step-by-step explanation:

1.

(a)

n>=m

(b)

n <= m

(c)

n=m

2.

(a)

let T(v1) = T(v2)

=>

T(v1)-T(v2) = 0

=>

T(v1-v2) = 0

=>

v1-v2 = 0 from the hypothesis

=>

v1=v2

=>

T is one-one

thus proved

(b)

lets assume T is onto, we already know that T is one-one, so from above problem (third case where m=n)

we should have 3=4 which is impossible

so T is NOT onto.

3.

we need to find a,b such that

T(a,b) =(a,b)

=>

a= b

=>

points on the line x=y are the required points

If y varies inversely as x and y = 18 when x = 4, what is y when x = 24
Nady [450]
Well, you must first do your equation k=y/x so k= 18/4 or 9/2
now you use the equation y= kx or y= 9/2 times 24... 9/2 times 24 is 108 so y=108

Andrew has $2.00 in quarters in his pocket, including three state quarters. He takes two quarters out of his pocket. What is the
Zolol [24]
$2.00 in quarters is 8 quarters, since 1 quarter is 25 cents.
Out of those 8 quarters, only 3 are state quarters.
That means 5 are not state quarters.
So there is a 5/8 chance that the first quarter he takes out is not a state quarter.
If it is not, then there are 3 state quarters and 7 total quarters left, which means a 4/7 chance that the second quarter is not a state quarter.
To find the probability of both of these quarters not being state quarters, multiply the probabilities by each other.
4/7 • 5/8 = 20/56
Now simplify:
20/56 = 10/28 = 5/14
5/14 is in simplest form, so it is the answer.
So the answer is D. 5/14.

Help! <br> The slope of the line below is -3.
mylen [45]

Answer:

D. y + 7 = -3(x - 5)

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

⇒ y - (-7) = -3(x - 5)

⇒ y + 7 = -3(x - 5)

2k - 10 = 6<br><br> Can someone help me I can't figure out the answer
PSYCHO15rus [73]
Hello ! 
 

Okay so what you do is add 10 to the other side

2k - 10 +10 = 6 + 10

You would get .... 

2k = 16

Next you divide 16 by 2 which is 8

and that means 8 is equal to k

K = 8
