1 root
2 roots
4 roots
5 roots
Answer:
Option 4 is correct that is according to fundamental theroem of algebra the given polynomial function will have 5 roots
Step-by-step explanation:
The fundamental theorem of algebra says that the polynomial will have the number of roots equal to the degree of the polynomial.
Degree is the highest power of polynomial.
Here we have given the polynomial where degree is 5.
Hence, the given polynomial will have 5 roots.
Therefore, option 4 is correct that is 5 roots
Answer:
Step-by-step explanation:
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. ... An equation or an inequality that contains at least one variable is called an open sentence.
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality)
oil. How can you remove the salt?
Answer: Evaporate the water by boiling it in a pot with a lid or another container. This separates both substances as the boiling point for water is much lower than salt, this method is called simple distillation.
Answer:
Salt is ionic, and oil is covalent. If you add water, the salt will dissolve in the water, and the oil will float to the top. You could then skim the oil and start over with sugar. To double-check, you could even make sure the oil does not conduct electricity!
Step-by-step explanation:
The distance between hometown and school is 188.75 miles.
Given that, the person drive 110 miles at 55 miles/hour.
Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula , where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.
Due to snow, speed is slow down to 35 miles/hour.
Let x miles be travelled with 35 miles/hour.
Total time taken to travel is 4 hours and 15 minutes.
Here, and
Now,
miles
Total distance = 110+78.75
= 188.75 miles
Therefore, the distance between hometown and school is 188.75 miles.

The total distance from school to the student's hometown is calculated as the sum of distances covered at different speeds. The student spends 2 hours at 55 mi/h, covering 110 miles, and then 2.25 hours at 35 mi/h, covering 78.75 miles, making up a total of 188.75 miles.
The question pertains to the concepts of distance, speed and time in mathematics. In this scenario, the student drives at a speed of 55 mi/h for 110 miles and then slows down due to snowfall and drives at 35 mi/h. From this information, we can calculate the time spent at each speed.
Firstly, since Speed = Distance / Time, we can rearrange to find Time = Distance / Speed. For the first stretch of the journey, the time is 110 miles / 55 mi/h = 2 hours.
It is given that the total journey takes 4 hours and 15 minutes which is equivalent to 4.25 hours. So, the time spent driving at 35 mi/h is 4.25 hours (total trip time) - 2 hours (first stretch) = 2.25 hours.
The distance covered when it was snowing can be found by multiplying this time by the slower speed: 35 mi/h * 2.25 h = 78.75 miles.
Therefore, the total distance from school to the student's hometown is the sum of the distance traveled at each speed: 110 miles (at 55 mi/h) + 78.75 miles (at 35 mi/h) = 188.75 miles.
