Answer:y = -4.5x - 22

Step-by-step explanation:

The standard form of finding the equation of a line is expressed as y = mx+c

m is the slope

c is the y intercept

Get the slope:

m = y2-y1/x2-x1

Given the coordinates (-6,5) and (-4,-4)

m = -4-5/-4+6

m = -9/2

m = -4.5

Get the y-intercept

Substitute (-4,-4) and m = -4.5 into y = mx+c

-4 = -4.5(-4) + c

-4 = 18 + c

c = -4-18

c = -22

Get the required equation:

Recall that: y = mx+c

y = -4.5x - 22

Hence the required equation is y = -4.5x - 22

Step-by-step explanation:

telo118 [61]
The number of times the tires will have to spin is 24.9 times. How I got this was by finding the circumference, the equation in this case where pi is 3.14 is 3.14(2.1). That equals 6.594, then you divide 164 by 6.594 to get 24.87109 blah blah and you round that up to 24.9.

Find the vertex, focus, directrix, and focal width of the parabola. (5 points)
Anarel [89]

\bf \textit{vertical parabola vertex form with focus point distance} \\\\ 4p(y- k)=(x- h)^2 \qquad \begin{cases} \stackrel{vertex}{(h,k)}\qquad \stackrel{focus~point}{(h,k+p)}\qquad \stackrel{directrix}{y=k-p}\\\\ p=\textit{distance from vertex to }\\ \qquad \textit{ focus or directrix}\\\\ \stackrel{"p"~is~negative}{op ens~\cap}\qquad \stackrel{"p"~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}

\bf -\cfrac{1}{20}x^2=y\implies \cfrac{x^2}{-20}=y\implies x^2=-20y\implies (x-0)^2=-20(y-0) \\\\\\ (x-\stackrel{h}{0})^2=4(\stackrel{p}{-5})(y-\stackrel{k}{0})

something noteworthy is that the squared variable is the "x", thus the parabola is a vertical one, the "p" value is negative, so is opening downwards, and the h,k is pretty much the origin,

vertex is at (0,0)

the focus point is "p" or 5 units down from there, namely at (0, -5)

the directrix is "p" units on the opposite direction, up, namely at y = 5

the focal width, well, |4p| is pretty much the focal width, in this  case, is simply yeap, you guessed it, 20.
