Write the first five terms of the sequence whose general term, an, is given
an= - 5n + 8

See Explanation

Step-by-step explanation:

1st term = an= - 5n + 8 = -5(1) + 8

= -5 + 8

a1 = 3

2nd term = an= - 5n + 8 = -5(2) + 8

= -10 + 8

= -2

3rd term = an= - 5n + 8 = -5(3) + 8

= -15 + 8

= -7

4th term = an= - 5n + 8 = -5(4) + 8

= -20 + 8

= -12

5th term = an= - 5n + 8 = -5(5) + 8

= -25 + 8

= -17

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

part d
