Answer:
57.6 km per hr
Step-by-step explanation:
Let us assume the horizontal distance between the ship is constant = x
= 70 Km
The ship A sails south at 40km/h is denoted as 40t
The Ship B sails north at 20 km/h is denoted as 20t
Now the vertical distance separating the two ships is
= 20t + 40t
= 60t
And, the Distance between the ship is changing
As x is constant
Now differentiating
The distance between two ships is at 4
So,
vertical distance is
= 240
And, the horizontal distance is 70
So, the distance between the ships is 57.6 km per hr
1) Answer is A (True). 5.7 can be written as fraction in which both numbers are whole finite numbers.
2) Answer is True. Explanation is same as for the previous question.
3) √24 is between 4 and 5. √16=4 and √25 is 5, therefore answer is D)
4) Answer is √136. 11²=121 and 12²=144 and the question doesn't include equal scenario which would look like "more or equal than 11 but less or equal than 12".
Step-by-step explanation:
the answer is in the image above
The answer is 1/40.First you have to do 1/4 times 10 which you put over 1 so 1/4 times 10/1,than you flip one of the #'s so 1/4 times 1/10 which equals 1/40
Answer:
slope =
Step-by-step explanation:
calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (2, - 9 ) and (x₂, y₂ ) = (12, 6 )
m = = = =
