Answer:
The roots of the equation are 
and 
Step-by-step explanation:
The roots of a quadratic equation y = ax² + bx + c are the values of x at y = 0
∵ y = x² + 2
- To find the roots of it equate y by 0
∴ 0 = x² + 2
- Switch the two sides
∴ x² + 2 = 0
- Subtract 2 from both sides
∴ x² = -2
- Take √ for both sides
∴ x = ± 
- There is no square root for negative numbers
∴ There is no real roots for this equation but there are imaginary roots
∵ 
∴ 
- Substitute 
by 
∴ 
∴ 
∴ The roots of the equation are and
Answer:
the answer would be c the
third option
Answer:
Independent variable: b - books
Dependent variable: w - weeks
graph attached
Step-by-step explanation:
b = 2w + 3
b = total number of books collected
w = is the number of weeks
So, the number of books depend on the number of weeks, so
Independent variable: b - books
Dependent variable: w - weeks
Volume= 367.54 Do you know the height and base? <span />
Independent Events are 2 events where the occurrence of the first doesn't affect the occurrence of the second and vice versa.
Example: rolling 2 simultaneously dies, the occurrence of the first, has no impact, no effect on the occurrence of the 2nd roll
