Okay so both my parents are permanent residents and want to bring my grandma for a visit. What papers, legal actions, or forms do my parents have to fill out also What does my grandma need besides passport. Any help is appreciated .

Given the matrix A

[1 4 5 2]

[2 1 3 0]

[-1 3 2 2]

I need to find the general solution for A x = 0 with vector arrows on top of x and 0.

Also the basis for the nullspace of A.

I found the Nullspace(A) which I got N(A) = spans { [-1 -1 1 0], [ 2/7 -4/7 0 1] }

but how would i find the general solution and the basis of N(A).

My first problem is figuring out how to reverse the string making input: string hello and hi

and changing it into : ih dna olleh.

My second problem if the do while loop and I can't seem to exit to display my while invalid choice loop.

Other than that everything else works fine.Also I was told not to use library functions only string and char operators. Thank you, your help is appreciated.

I need help understanding this problem.

Le T: R^2 --> R^3 be a linear transformation such that T(e1) = u1 and T(e2) = u2, where

u1 = [ 1 0 -1 ] and u2 = [2 1 0 ]

i need to figure out one and i can figure out the rest

find

a) T ( [ 1 1 ] )

thank you in advance

Hello I am having trouble understanding the problem and how to start.

let T: R^2 --> R^2 be a function given in exercise 1. show that for each B in R^2 , there is an x in R^2 such that T(x) = b.

function from exercise 1

T: R^2 --> R^2

T([x1 ]) = [ 2x1 - 3 x2]

[x2] [-x1 + x2 ]

thank you any help will be appreciated

I need help in these following problems show work.

1.prove the identity. tan^2 (x/2 + π/4) = (1+sin x)/ (1-sin x)

2.find an angle between 0 and 2π that is coterminal with the given angle.

a. -7π/3

b. 10 radians

3. Find the exact value of the expression. cos [sin^ -1 (5/13) - cos^ -1 (4/5)]

I need help in these following problems show work

1.find all solutions of the equation. sin^2x = 4 - 2cos^2x

2.convert the given polar equation to rectangular coordinates. r = 1 / (1+sinθ)

your help is appreciated i will give 10 points to the one who answers both with work

Do you believe Welfare should be a one shot thing and only for a limited time? Also who do you think will be against this?
