Question

1.If the value of the expression x raised to the power 2 – 5x + k for x = 0 is 5, then the value of k is



2.Find the value of the expression z raised to the power 3 – 2(z – 10) for z = 10

3. Find the value of the expression a raised to the power 2 + ab + 1 for a = 0, b = 1

Answer 1

Step-by-step explanation:

1) p(5)=2-5*5+k

=-23+k

23=k

2) p(z)=3-2(z-10)

=z-10

10=z

3)p=2+0*1+1

=3
