Answer:
Average speed of the two boats are 28 km/hr. and 24 km/hr.
Step-by-step explanation:
Let the average speed of the boat with larger speed is x km/h and that of the other boat is y km/h.
Now, given that x - y = 4 ...... (1)
If the distance, that the first boat covers in 3 hrs. is d km then the second boat covers d km in 3.5 hrs.
Therefore, and
Now, from equation (1), we can get
⇒
⇒ km/hr.
Again, km/hr.
Therefore, the average speed of the two boats is 28 km/hr. and 24 km/hr. (Answer)
Next 3 terms will be 22 29 37 and 20th number will be 232
Dividing by x-2 yields 3x^4 + 6x3+5x^2-x + 2/(x-2)
Therefore it is not a factor.
Answer:
-15
Step-by-step explanation:
1/-13
The reciprocal is
Because of the law of indices,
We'll have
= -13.
-1/2
The reciprocal is
1 ÷ -1/2
Because of the law of indices,
We'll have
= -2
Therefore, the sum would be -13 + (-2) which would be equals to -15.
