Answer:
Isnt it -3?
Step-by-step explanation:
7y. the 7x cancels out and if u distribute, it's 7y.
Start off by doing
64/1000
that should equal 0.064
0.064 and quare it by 3
0.4
which equals 4/10
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
