Not all of them, like what do you think about a circle?

helped? :)

Not all shapes, a right triangle does not have any parallel sides.

I hope this helped!

A book has a mass of 50 kilograms and an acceleration of 5 m/s/s. What is the force on the book?

ankoles [38]

Answer:

The force on the book is 250N.

Step-by-step explanation:

Newton's second law states that the equation for the force is:

$F = ma$

In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.

In this question:

$m = 50, a = 5$

$F = ma = 50*5 = 250$

The force on the book is 250N.

Ayuda con mi tarea de matemáticas , dice asi : En una biblioteca hay 5 estantes , 2/5 de uno de ellos está ocupado por libros de

laiz [17]

There are 5 shelves in the bookcase.

2/5 of one shelve is occupied.

That would be:

2/5*1/5=2/25 of all shelves

7/2 is more than 1, so it refers to the bookcase instead of one shelve. The same with 11/10.

So the total is:

2/5+7/2+11/10 = 5

So all shelves are completely full.

So there is no room for any other book.

Let pn denote the set of all polynomials of degree at most n with real coefficients (i.e. polynomials of the form a0+a1t+a2t 2+.

Gekata [30.6K]

We can consider each unique $t^i$ as the as the $i$ -th unit vector. So your set $s$ can be considered as the vectors

$\langle 1, 0, 0 \rangle, \langle 0, 1, 1 \rangle,\langle 0, 3, 4 \rangle$

Then check for independence your favorite way. In this case, I'll see if the linear map A of the new basis vectors doesn't map to a subspace via the determinant not being zero:

$det(A) = det \left ( \left [ \begin{array}{ccc} 1 & 0 & 0 \\ 0 & 1 & 3 \\ 0 & 1 & 4 \end{array}\right ] \right ) = 1(4-3) = 1$

So they are linear independent.
