Very first one, A
Step-by-step explanation:
Answer:
It will take <u>600 seconds</u> for Mia to run 400 meters.
Step-by-step explanation:
Given:
Mia ran 2/3 meters per second.
Now, to find how long will it take for Mia to run 400 meters.
Distance = 400 meters.
Speed = 2/3 meters per second.
So, to find the time it will take for Mia we put formula:






Therefore, it will take 600 seconds for Mia to run 400 meters.
Ends up being ten after all the steps but if you add one after that the answer is 11
Step-by-step explanation:
the average rate of change is the change of the functional values over a given interval relative to (= divided by) the interval length (the change of the input variable in that interval).
in short :
( f (interval upper limit) - f (interval lower limit) ) /
(interval upper limit - interval lower limit)
upper limit = 8
lower limit = 0
the functional values (y) at these points are 36 and 12.
so, we get
(36 - 12) / (8 - 0) = 24 / 8 = 3
or
3/1
Answer: The correct option is 1.
Explanation:
The given piecewise function is,

It means if x<0, then

If
, then

Since the f(x) is defined for x<0 and
, therefore the function f(x) is not defined for
.
From the graph 2, 3 and 4 we can easily noticed that for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.
Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for
, hence the first option is correct.
