There is only one change of sign, so there is only one possible positive root.
There are five changes of signs, so there are 5,3 or 1 possible negative roots.
The number of complex roots can be equal to 4,2 or 0 (degree of a polynomial - possible positive roots - possible negative roots)
Answer:
4 feet.
Step-by-step explanation:
Let x be the height of tower when finished.
We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.
This means that 5/8 of x equals 
. Let us represent this information in an equation.
Let us convert our given mixed fraction into improper fraction.
Let us multiply both sides of our equation by 8/5.
Therefore, the tower will be 4 feet tall when finished.
14.18 because you do pi times the radius squared and divide it by 2.
Answer: 150
Step-by-step explanation:
You got it right, just divide 300 by 2 :)
Answer:
24
Step-by-step explanation:
Use PEMDAS:
Parenthesis:
(27-19)=(8)
Then multiplication:
6+(2*3)+4+(8)
6+(6)+4+(8)
Then add everything:
24
