It depends if you need to simplify it. If you dont than three. If you do than 2
Answer:
1.16ft tall.
Step-by-step explanation:
168/144= 1.16 ft tall
or rounded to the nearest number = 1.20 ft.
Answer:
D. 4.5%.
Step-by-step explanation:
Interest earned in 6 months = 572.6 - 560 = $12.60.
As a percentage this is (12.60 * 100) / 560
= $ 2.25%.
So the annual interest is 2 * 2.25
= 4.5%.
You follow the rules for the quadratic formula, where
x= (-b +- √(b²-4ac) )/2a
Filling a, b and c in yields
x = (8 +- √(64-164) ) / 2 =>
x = (8 - √-100)/2 or x = (4 + √-100)/2
Well, √-100 = 10i, so then you simplify to the last answer, D:
x = 4-5i or x=4+5i
Answer: This is a statement. This is not a question.
