Answer:
Step-by-step explanation:
For the quadratic equation 
the discriminant is defined as
and the quadratic formula for the roots gives us two roots:
and
For the equation 
use quadratic formula to find roots:
So,
I think its called a sequence
5.8x10^-10 is already in sciencific notation. To convert it to normal notation you move the decimal either the right OR left the number of places the exponet says. This case it is 10, but the negative determines the direction which is left (negative is left and positive is right.) Thus your answer is 0.00000000058

Step-by-step explanation:
Answer:
s = 3h
0.1s + 0.2h = 5
h = 10
s = 30
Step-by-step explanation:
Given that :
Hat :
0.2kg of yarn
Let Number of hats = h
Kg of yarn used for hat = 0.2 * h = 0.2h
Scarf:
0.1 kg of yarn
Number of scarves (s) = s
Kg of yarn used for scarf = 0.1 * s = 0.1s
Total kg of yarn used = 5 kg
Number of Scarf = 3 times number of hats :
s = 3h - - (1)
0.1s + 0.2h = 5 - - (2)
From 1:
0.1(3h) + 0.2h = 5
0.3h + 0.2h = 5
0.5h = 5
h = 10
s = 3h
s = 3(10) = 30
