The function y = x * ln(x + e) has two distinct x intercepts. One is at x = a and the other is at x = b. The value of a + b is
Snezhnost [94]
As points, x-intercepts take the form (x,0), so to find the intercepts we can set y=0 and solve for x.

x\ln(x+e)=0\implies\begin{cases}x=0\\\ln(x+e)=0\end{cases}

From the first equation alone, we already know that x=0 is a solution, which means one intercept is (0,0).

The second equation gives

\ln(x+e)=0\implies e^{\ln(x+e)}=e^0\implies x+e=1\implies x=1-e

so that the second intercept occurs at (1-e,0).

So if a=0 and b=1-e, we have a+b=1-e, giving C as the answer.

How many ways are there for six dogs and four cats to sit in a row in a strawberry field so that no two cats sit next to each ot
pickupchik [31]

Answer: 5,760

Step-by-step explanation:

\\It was given that each dog is distinct from other dogs and each cat is distinct from other cats, Also from the hint given, the First position is for the dogs. \\Let D represent the dogs and C represent the Cat , then we have

\\D C D C D C D C D D   or

\\D  D C D C D C D C D  or

\\D C DD C D C D C D or

\\D C D C D D C D C D or

\\D C D C D C DD C D

\\Each of the arrangements above  could be done in

\\2 x 4! x 4!  ( it is constant that D is starting , so I am only left with the arrangement of the remaining 5 D's  , out of the remaining 5 D's it is also constant that tow of them will be together and this could be done in 2 ways, so I have 4! left for the D's and 4! also for the C's )

\\= 2 x 24 x 24

\\ = 1 , 152

\\The total arrangement = 5 x 1 , 152

\\= 5,7 60 ways

Zhang is designing protective packaging. He tests his design by dropping a raw egg protected by his packaging from various heigh
Softa [21]

Answer: 12.034 yards

Step-by-step explanation:

Given the following :

Height to which egg is protected = 11 meters

Converting this height of 11 meters to yards

Let the height in yards = h

1 meter = 1.094 yards

11 meters = h

(1 * h) = (11 * 1.094)

h = 12.034 yards

Hence, the height in yards to which egg is protected = 12.034 yards
