1. John earns $10 per hour for any work up to 40 hours. For any time over 40 in a week, he receives 1.5 times his normal pay. Ho
yanalaym [24]

Answer:

1. 520

2. 568.125

Step-by-step explanation:

1.

10 per 40 hours + 1.5 overtime

1.5 overtime = 10(1.5) = 15

10 (40) + 15 (8)

= 400 + 120

= 520

2.

11.25 per 40 hours + 1.5 overtime

1.5 overtime = 11.25(1.5) = 16.875

11.25 (40) + 16.875 (7)

= 450 + 118.125

= 568.125

A) Find a polynomial, which, when added to the polynomial 5x2–3x–9, is equivalent to: 18
VMariaS [17]

Answer:

a) -5x^{2}+3x+27

b) -5x^{2}+3x+9

Step-by-step explanation:

a) Let the required polynomial be p(x).

We have the relation, 5x^{2}-3x-9 + p(x) = 18

i.e. p(x) = 18 -5x^{2}+3x+9

i.e. p(x) = -5x^{2}+3x+27


b) Let the required polynomial be q(x).

We have the relation, 5x^{2}-3x-9 + q(x) = 0

i.e. q(x) = 0 -5x^{2}+3x+9

i.e. q(x) = -5x^{2}+3x+9
