Answer:
(a) 11.
(b) 5.
Step-by-step explanation:
(a)√124:
11*11 = 121 so an estimate is 11.
(b) ∛124
5*5*5 = 125
So an estimate is 5.
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
Step-by-step explanation:
357-200 is 157 extra minutes (we are only counting the extra minutes)
157*0.25 is 39.25 (this is how much is the extra minutes in total cost)
therefore, add 39.25 and 29.99
29.99+39.25 is 62.24
Therefore, the total bill was $62.24
hope this helps :)
Have a nice day !
