4. Which equation describes the line that contains the points (6,2) and (12,4)?
saveliy_v [14]

Answer:

(a) y = 1/3 x is the correct equation.

Step-by-step explanation:

The given points are (6,2) and (12,4)

Now, if these points lie on any equation then they should satisfy the equation on which they lie.

CHECK FOR  equation  y = 1/3 x

if x = 6, y = 2 , then 2 = 1/3(6)  , True

if x = 12, y = 4, then 4 = 1/3(12). True

So, y = 1/3x contains both the points.

CHECK FOR  equation  y = 3x + 2

if x = 6, y = 2 , then 2 ≠ 3(6) + 2  

if x = 12, y = 4, then 4 ≠ 3(12). + 2

So, y = 3x  + 2  do not contain both the points.

CHECK FOR  equation  y = 3x  

if x = 6, y = 2 , then 2 ≠ 3(6)  

if x = 12, y = 4, then 4 ≠ 3(12).

So, y = 3x  do not contain both the point

Hence,  (a) y=1/3x is the correct equation.

A jar contains two red marbles, three green marbles, ten white marbles and no other marbles. two marbles are randomly drawn from
neonofarm [45]
Since there are only 2/15 red marbles in the jar, to draw the first marble it would be a 2/15 chance, the next draw would only have 14 marbles, and only 1 red marble, giving you a 1/14 chance. Then you would just need to multiply those two together giving you 2/210, which you can simplify to 1/110

Verify that the function satisfies the three hypotheses of Rolle's Theorem on the given interval. Then find all numbers c that s
RSB [31]
Well, is the function continuous?  yes, is a cubic one, you can graph it if you wish, is continuous all the way, and of course at [ 0, 4] too.

is it differentiable?  you can always look at the graph between 0,4 and is a smooth transition line, thus yes, it is differentiable, but let's check anyway,

\bf \cfrac{dy}{dx}=3x^2-2x-12    its derivative has no asymptotes and therefore no "cusps", so yes, is differentiable all around.

is f(0) = f(4), let's check

f(0) = 0+0+0+3,            f(0) = 3
f(4) = 64 - 16 - 48 + 3,   f(4) = 3

yeap

there must then be a "c" value(s) with a horizontal tangent slope, let's check, is really just the critical points.

\bf \cfrac{dy}{dx}=3x^2-2x-12\implies 0=3x^2-2x-12&#10;\\\\\\&#10;\textit{using the quadratic formula}&#10;\\\\\\&#10;x=\cfrac{-(-2)\pm\sqrt{(-2)^2-4(3)(-12)}}{2(3)}\implies x=\cfrac{2\pm\sqrt{4+144}}{6}&#10;\\\\\\&#10;x=\cfrac{2\pm 2\sqrt{37}}{6}\implies x=\cfrac{2\pm\sqrt{37}}{3}\impliedby \textit{c's}
