Suppose X1, X2,,,,, Xk are vectors in R^n and U=span{X1,X2,,,,,Xk} and suppose that A is an mxn non zero matrix such that AXi = 0 for i= 1,,,,,k. Show that U is not all of R^n.

Thanks for the help in advanced !

When is the particle speeding up and slowing down? Use interval notation

s(t)=t^4-72t^2+1296

I figured out that

v(t)=4t^3-144t

a(t)=12t^2-144

Thank you in advance

and where is the function concave up and down

heres what i did

f'(x)= -e^(x)^2(2x^2+1) and f "(x) = -2xe^(x)^2(2x^2+3)

I think its concave up at (-inf,0) and concave down at (0,inf)

Thank you in advance!

the website is electronicsinc.miiduu.com theres no www. in it But i really liked it and i want to know what you think about it

For complete neutralization, 15.0 of 0.35 mol/L sodium hydroxide was required to react with 0.425 g of an acid. Calculate the molar mass of the acid, assuming the acid is monoprotic and requires a 1:1 mole ratio to react.

Thank you in advance

use common denominators to find each quotient 2 over 3 divided by 1 over 2, second question 5 over 6 divided by 3 over 4.

sam uses 2 thirds of a roll of ribbon to tie one balloon for the school dance. He has 12 rolls of ribbon. How many can he tie? Second question a student knows that 3 over 3 x 4 is the same as 4x 3 over 4. The student assumes that 4 divided by 3 over 4 is the same as 3 over 4 divided by 4. Is the student correct?
