There are no real solutions to the quadratic equation.
Hope this helps.
Factors are numbers that can be multiplied by an integer to obtain the desired integer
The size of the human hair is <u>1.0 × 10⁻⁴ meters </u>
Reason:
The given parameters are;
The size of an hydrogen atom is 5 × 10⁻¹¹ meters
The width of the human hair is 6 times as big
Therefore, we have;
The width of the human hair is 2 × 10⁶ times as big, therefore, we have;
The size of the human hair = 5× 10⁻¹¹ × 2 × 10⁶ = 1.0 × 10⁻⁴
The size of the human hair is <u>1.0 × 10⁻⁴ meters</u>

(9,3) is the point that isn’t on the graph
2t + j = 80
3(0.5)t + 2(0.5)j = 70
j = 80 - 2t
1.5t + j = 70
1.5t + 80 - 2t = 70
-0.5t = 70 - 80
-0.5t = -10
t = -10/-0.5
t = 20
j = 80 - 2t
j = 80 - 2(20)
j = 80 - 40
j = 40
so ur answer is C
