) /
= (-6 ±
)/4= (-3 ± i)/2
x1 = -3/2 +i
x2 = -3/2 -i
Answer:

Step-by-step explanation:
To find the required probability,
We can split the 40 years of Eric into very small pieces of time dt. Now, If Eric dies at time t and Gary dies before Eric, the probability is :

Hence the probability that Gary dies first is given by :

The approximate distance that Sabrina traveled in one revolution of the Ferris Wheel is A).45,972.74ft
Answer:
25 unit
Step-by-step explanation:
See attachment for the missing figure.
Assuming the complete question is:
Side UY = 4z-1
Side UV = 5z+3
Perimeter of rectangle is given by:
2UY+2UV=P
2(4z-1)+2(5z+3)=84
8z-2+10z+6=84
18z+4=84
18z = 84 -4 =>
18z = 80
z= 4.45 unit
Side UV = 5z+3 => 5(4.45) + 3
Side UV ≈ 25 unit
SInce, Side UV = Side XY
Side XY≈ 25 unit
