Line j is perpendicular to the line with the given equation and the line j passes through p. write an equation of line j

1 answer:

8 0

Using the slope intercept formula, we can see that the slope of line p is 3/5.Since line j is perpendicular to line p it must have a slope that is the negative reciprocal(-5/3).Using the formula we can find the answer.j:y-1=-5/3(x-5)
Doing some math we get:5x+3y=28

A cylindrical tube has a radius of 4 inches and a height of 14 inches could some one help me find the volume

pickupchik [31]

The volume of the cylinder is the area of the base (a circle) times the height (you can immagine taking a disk, the base, and translate it along the height to "fill" the cylinder).
So you have:
$V=area.circle*height= \pi r^{2}*h = \pi 4^{2} *14=703.4 in^{2}$

Jayden has been reading a 275275275-page book for English class. On average, he has read about 101010 pages in 151515 minutes (\

maxonik [38]

First let's define variables:
r: reading
s: skimming
We write the system of equations that adapts to the problem:
r + s = 275
(15/10) r + (10/15) s = 355
We solve the system of equations:
r = 206
s = 69
Note: see attached image for system solution.
Answer:
Jayden had to skim 69 pages through
