Answer:
In the given expression x:6 :: 3:9 , x = 2
Step-by-step explanation:
Here, the given expression is:
x:6 :: 3:9
or, x : 6 = 3 :9
So, by the RATIO OF PROPORTIONALITY:

or, x = 2
Hence, in the given expression x:6 :: 3:9 , x = 2
You just divide the distance travelled by the time like so: 145mi/2.5h and get 58mph. You can convert the 145mi into meters and 2.5h into seconds (145mi is approximately 233345m; 2.5h is 9000 seconds) and get an approximate speed of 26m/s if you want to convert to SI units.
Answer:
I don't understand.
Step-by-step explanation:
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
