Answer:

5 meters per second.

Step-by-step explanation:

There are 60 seconds in 1 minute:

1 minute 20 seconds = 60 seconds + 20 seconds = 80 seconds.

Divide the amount of meters swam (400) with the total amount of seconds used (80) to get the average meters per second:

(400 meters)/(80 seconds) = 5 meters/second.

5 is your answer.

Answer:

5 MPS

Step-by-step explanation:

If Ciera can swin 400 meters in 1 minute and 20 seconds,

400 meters = 1 minute 20 seconds (1 1/3 minutes).

Divide both sides by 1 1/3.

400/ 1 1/3 = 300

Since it asks in seconds, divide by 60.

300/60=5

How many complex roots does the polynomial equation below have? x^5 - 3 = 0
const2013 [10]

For any polynomial equation, The Fundamental Theorem of Algebra tells you that the highest degree present will tell you how many complex roots the equation has. There are only two terms, "x^{5}" and "3". The x^{5} term has a degree of 5, its exponent. The 3 term has a degree of zero, because you could write it as 3 * x^{0} = 3 * 1 using the zero exponent rule.


The degrees present are 5 and 0. Choose the highest one, 5. So, the answer here is D.
