Three manufacturers of plastic products a,b and c received an order to make 1950 plastic filters in the ratio 7:8:11.
leva [86]
7+8+11=26

So the first manufacturer  makes  7/26 of all filters
      the socond one makes    8/26 of all filters
and the third one makes  11/26 of all filters

A)
Number of plastic filters A:
                                               A=\frac7{26}\cdot1950=7\cdot75=525
Number of plastic filters C:
                                               C=\frac{11}{26}\cdot1950=11\cdot75=825

B)
Number of plastic filters B:
                                                       B=\frac8{26}\cdot1950=8\cdot75=600
85cents = 0,85$ (or €?)
Amount of money B will receive:
                                                         600\cdot0,85=6\cdot85=510
C)
The main thing that will change is the number of plastic filters to make:

1950-338=1612
So:
     Number of plastic filters A:
                                                    A=\frac7{26}\cdot1612=7\cdot62=434
     Number of plastic filters B:
                                                    B=\frac8{26}\cdot1612=8\cdot62=496
     Number of plastic filters C:
                                                    C=\frac{11}{26}\cdot1612=11\cdot62= 682

Based on its degree, what kind of polynomial is this <br><br> h(x)= -6x^3+2x-5
Lelechka [254]

Answer:

cubic polynomial

Step-by-step explanation:

Given polynomial is \[h(x)=-6x^{3}+2x-5\]

A polynomial of degree 1 is a linear polynomial.

A polynomial of degree 2 is a quadratic polynomial.

A polynomial of degree 3 is a cubic polynomial.

In this case the exponent with the maximum value in the polynomial is 3.

Hence the degree of the polynomial h(x) is 3.

Hence the given polynomial is a cubic polynomial.
