30 points 1 question PLEASE HELP ME OUT I REALLY NEED IT
Pachacha [2.7K]

Answer:

p(-5/3) ≠  0 So, (3 x +5) is NOT A FACTOR of p(x)

Step-by-step explanation:

Here, the given function is p(x)=3x^5+2x^2 - 5

Now, the given root of the function is ( 3x +5)

Now, if ( 3 x +  5) = 0,

we get x = - 5/3

So, the zero of the given polynomial is x = -5/3

Then,  x = -5/3, p(x)  =0 ⇒   ( 3 x + 5) is a FACTOR of p(x)

Now, let us find the value of function at x = -5/3

Substitute x = -5/3 in the given function p(x), we get:

p(x)=3x^5+2x^2 - 5  \implies p(\frac{-5}{3})  = 3(\frac{-5}{3})^5 + 2(\frac{-5}{3})^2 - 5\\= 3(\frac{-3,125}{243}) + 2(\frac{25}{9})  - 5\\= (\frac{-3,125}{81}) + (\frac{50}{9})  - 5\\= -38.580 + 5.56  - 5  =  -38.02\\\implies p(\frac{-5}{3})  = -38.02

Now, as p(-5/3) ≠  0 So, (3x +5) is NOT A FACTOR of p(x)

In the following problem, how much money does each person need to make!
NikAS [45]

Answer:

40

Step-by-step explanation:

X(amount of people)

Y(Total amount made)

Y/X=40

Chad plus his other 5 friends makes 6 people.

Y/6=40

*6 *6

Y=240

The money would be split evenly.

Z(Amount each person needs to make)

240/60=Z

40=Z

They each need to make 40, which makes sense because they would be earning the amount they make.
