Answer:
4 miles per hour.
Step-by-step explanation:
2 hours = 28 miles downstream; 14 miles per hour
3 hours = 18 miles upstream; 6 miles per hour
The boat went faster when going downstream meaning the current is going towards up stream. I would find the average speed, (14+6=20/2=10 m/h average) and determine subtract the average from the speed from wither upstream or downstream. 14- 10= 4 and 10- 6= 4. Therefore the stream's current is 4 miles per hour.
<h3>Osa is closer because 200 is smaller than 311</h3>
Because Osa is below sea level, we use a negative value to represent the height. Osa's height is -200. When comparing distances to 0, we just focus on the positive version of each number.
The polynomial is:
Step-by-step explanation:
We need to write a polynomial f(x) that meets the given conditions: Degree 3 polynomial with zeros 3,-5,4
Since zeros are at 3,-5 and 4
So, x=3, x=-5 and x=4
or:
x-3=0, x+5=0 and x-4=0
Multiplying all factors to find the polynomial:
So, the polynomial is:
