The first four terms of a pattern are given below.

4, 0, -4, -8,

what is the eighth term of the pattern?

a.-24
b.-8
c.-20
d.-28

4,0-4,-8,-12,-16,-20,-24

A

Or we can calculate it by using arithmetic sequence:

a8=a1+(n-1)•r

a8=4+(8-1)•(-4)

a8=4-32+4

a8=-24

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
