Answer:
If the roots of an equation are x = -1 ± i, it means that the factorized form of that equation is: (x + 1 + i)(x+ 1 - i) = 0.
Using the distributive property, we have:
(x + 1 + i)(x+ 1 - i) = x^2 + x - ix + x + 1 - i + ix + i + 1
Combining like-terms and simplifying:
⇒ x^2 + x + x + 1 + 1 = x^2 + 2x + 2 = 0
Therefore, the stament is correct. If the roots of an equation are x = -1 ± i, then the equation is: x^2 + 2x + 2 = 0.
Answer:
a) Junnie walked farther than Maurice
b) Junnie walked .62 miles farther than Maurice
Step-by-step explanation: Because speed times time equals distance, to find how far each person traveled you multiply their speed and time.
Distance=speed×time
Junnie:
2.5hrs×3.2mph=8 miles
Maurice:
1.8hrs×4.1mph=7.38 miles
8-7.38=.62 (the difference between the two)
X = 23
x - 7
(23) - 7 = 16
16 is your answer

Answer:
Radius = 6.5cm
Diameter = 13cm (given)
Step-by-step explanation:
The diameter is the length of one side of a circle to the other. It's already given in the diagram as 13cm.
The radius is half of the diameter. 13 divided by 2 is 6.5cm.
