Answer:

(0,-4)

Step-by-step explanation:

The y-intercept is where the line intersects the y-axis. The y-intercept is written in the form (0,x), where x = y-coordinate/y-intercept. Thus, the answer is (0,-4).

A particle starts at the point P=(−5,−1,3) when t=0 and moves along a straight line toward Q=(−6,−6,8) at a speed of 9 cm/sec. L

navik [9.2K]

Answer:

Step-by-step explanation:

Given

Particle moves from $P\ (-5,-1,3)\ to\ Q\ (-6,-6,8)$

speed of particle is $v=9\ cm/s$

Unit vector in the direction of vector $\vec{PQ}$ is given by

$\hat{n}=\frac{\vec{Q}-\vec{P}}{|\vec{Q}-\vec{P}|}$

$\hat{n}=\frac{-}{\sqrt{(-1)^2+(-5)^2+(5)^2}}$

$\hat{n}=\frac{}{\sqrt{1+25+25}}$

Now Position of Particle at any time is given by

$\vec{r(t)}=velocity\cdot time\cdot direction$

$\vec{r(t)}=9\cdot t\cdot \frac{}{\sqrt{1+25+25}}$

Parametric vector equation is given by

$x=\frac{-9t}{\sqrt{51}}$

$y=\frac{-45t}{\sqrt{51}}$

$z=\frac{45t}{\sqrt{51}}$

The perimeter of a certain soccer field is 310 m. The length is 65 m more than the width. What are the dimensions?

Dmitriy789 [7]

Answer:

50x105m

Step-by-step explanation:

310 (length of field) - 65-65= 200/4=50

Start with the perimeter subtract 65 twice because the length is on two sides. Now the length and width will be equal so divide by 4. Add 65 back because you subtracted it earlier.
