Ainat [17]

Answer:

2.7 hours or 2 hrs, 42 min

Step-by-step explanation:

to find the total number of sentences remaining we can multiply 130 sentences times 20 pages remaining to get

2,600 sentences

if we divide that number by 16 we'll get the number of minutes he needs to finish the novel

2600/16 = 162.5 minutes which, when divided by 60, is 2 7/10 hours

7/10 = 42/60 so it comes out to 2.7 hours or 2 hrs, 42 min

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

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)
