Perimeter = x + 5x - 2 + 7x - 4

= 13x - 6 meters answer

$P(x)=x+5x-2+7x-4$
$P(x)=13x-6$

Hope this helps !

A vehicle arriving at an intersection can turn right, turn left, or continue straight ahead. The experiment consists of observin

Temka [501]

Answer:

a) Sample space (S) = {TR, TL, Cs}

b) Pr(Vehicle Turns) = 2/3.

Step-by-step explanation:

a) By sample space (S) we mean the list all possible outcome of an event. From the illustration in the question, only three (3) outcome is possible:

i) Vehicle Turn Right (TR)

ii) Vehicle Turn Left (TL)

iii) Continue Straight ahead (Cs)

And since the experiment consists of observing the movement of a single vehicle through the intersection, then, the sample space (S) is:

==> {TR, TL, Cs}

b) Since we are assuming that all sample points are equally likely, it imply that they have equal probability of occurring. And by probability:

Pr(TR) = 1/3

Pr(TL) = 1/3

Pr(Cs) = 1/3

Meanwhile, the question wants us to find the probability that the vehicle turns. This means, the vehicle turning either right or left. Thus;

Pr(vehicle turns) = Pr(TR) or Pr(TL) = Pr(TR) + Pr(TL)

Pr(vehicle turns) = (1/3) + (1/3) = 2/3

Assuming you mean
$\lim_{x \to 4} \frac{\sqrt{x+5}-3}{4-x}$

that means as x approaches 4

if we sub 0 for x we get
0/0
and intermitent form
use l'hopital's rule

so
take the derivitive of the top and bottom seperatly
l'hopitals rule is something like
if $\lim_{x \to n} \frac{f(x)}{g(x)}$ results in 0/0 or -∞/∞ or∞/∞ then keep doing it until f(n)/g(n) gives a form that isn't intermitent

so

take derivitive of top and bottom
$\dfrac{\frac{1}{2\sqrt{x+5}}}{-1}$
now, if we subsitute 4 for x we get
$\dfrac{\frac{1}{2\sqrt{4+5}}}{-1}$ =

$\dfrac{\frac{1}{2\sqrt{9}}}{-1}$ =

$\dfrac{\frac{1}{2(3)}}{-1}$ =

$\dfrac{\frac{1}{6}}{-1}$ =

$\dfrac{1}{-6}=\dfrac{-1}{6}$

Which of the following best describes the set of even integers from 8 to 16

Tresset [83]

Answer:

(8, 10, 12, 14, 16) is the set which describes the set of even integers from 8 to 16

Step-by-step explanation:

To find the set of even integers from 8 to 16 as below :

There are 8,10,12,14,16 even integers in between the numbers 8 and 16

Therefore (8, 10, 12, 14, 16) is the set which describes the set of even integers from 8 to 16
