Find parametric equations through point P=(2,2,7) in the direction of the vector v = (44, 14, -20)?

ycow [4]

9514 1404 393

Answer:

(x, y, z) = (2+44t, 2+14t, 7-20t)

Step-by-step explanation:

One way to write parametric equations for line L is ...

L = P + t·<em>v</em>

where P is the given point and <em>v</em> is the given direction vector. Using that form, we have ...

(x, y, z) = (2+44t, 2+14t, 7-20t)

If you like, you can remove a common factor of 2 from the coefficients of t.

(x, y, z) = (2+22t, 2+7t, 7-10t)

3z^2-4z+11 -(12z^2+2z-11 find the difference . polynomials functions

Brrunno [24]

Answer:

−135z

−2z
The 2 is representing Square

Step-by-step explanation:

(3z)
2

−4z+11−(12z)
2

+2z−11

Expand (3z)

−4z+11−(12z)

+2z−11

Calculate 3 to the power of 2 and get 9.

−4z+11−(12z)

+2z−11

Expand (12z)

−4z+11−12

+2z−11

Calculate 12 to the power of 2 and get 144.

−4z+11−144z

+2z−11

Combine 9z

and −144z

to get −135z

−135z

−4z+11+2z−11

Combine −4z and 2z to get −2z.

−135z

−2z+11−11

Subtract 11 from 11 to get 0.

−135z

−2z
