g(x) = -3x² - 2x + 3

g(-2) = -3(-2)² - 2(-2) + 3

g(-2) = -12 + 4 + 3 = -5

Determine the projection of u=1.6i+3.3j in the v=-2.1i-0.5j direction

Lina20 [59]

The projection of $\vec u$ onto $\vec v$ is

$\mathrm{proj}_{\vec v}(\vec u)=\dfrac{\vec u\cdot\vec v}{\vec v\cdot\vec v}\vec v$

We have

$\vec u\cdot\vec v=1.6\cdot(-2.1)+3.3\cdot(-0.5)=-5.01$

$\vec v\cdot\vec v=\|\vec v\|^2=(-2.1)^2+(-0.5)^2=4.66$

$\implies\mathrm{proj}_{\vec v}(\vec u)=\dfrac{-5.01}{4.66}\vec v\approx2.26\,\vec\imath+0.54\,\vec\jmath$

Which expressions are polynomials? Select each correct answer. 30y^2 30y^2+x 30y2x 30y2+x12

gregori [183]

To know which of the following expressions are polynomials, let us look at the definition of a polynomial:

Polynomial is derived from poly- (which means "many") and -nomial (meaning "term"), so it says "many terms".

For an instance: $2x^2y+2y^2$ is a polynomial, but $4xy^2$ is not a polynomial because it contains single term only.

We must keep in mind that in polynomial it can have variables, constants, and exponents but it can never have division by a variable.

Now lets, look at the

$30y^2$ since it has got one term it can not be a polynomial.

$30y^2+x$ : it has got more than one term therefore, it is a polynomial.

$30y^2x$ : again it has got just one term so it is not a polynomial.

$30y^2+x^{12}$ : Since it has got more than one term, so again it is a polynomial.
