I don’t know dawg sorry g
Answer:
continuous.
Step-by-step explanation:
Given function is
.
and value of a = 7.
Now we need to find if the given function
is continuous or not.
By definition of continuity, we know that a function is continuous at a given point if both left and right hand limits are equal.
Left Hand Limit = LHL

Right Hand Limit = RHL

Since both limits are equal at a=7 so we can say that given function is continuous at a=7
Let b and s be the velocity of the boat and stream respectively....
3(b-s)=27
b-s=9
b=9+s we will use this in the second equation....
2(b+s)=30
b+s=15, now use b found above in this to get:
9+s+s=15
2s+9=15
2s=6
s=3, and since from earlier b-s=9, b=9+s so
b=12
So the speed of the boat is 12mph and the stream is 3 mph
300,000cm is equals to 3km
