Find the zeros of following quadratic equation and verify the relationship between the zeros and the coefficient.
1)4s2-4s+1

1/2, You know that the parabola will touch in only one point on the x-axis (zero) because both factors are the same.

Step-by-step explanation:

4s²-4s+1=0

(2s-1) (2s-1)  = 0

2s-1=0

2s=1

s=1/2

Graph attached so you have a visual.

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
