Answer:

Step-by-step explanation:
1.Convert all volumes to millilitres
(a) Chlorpheniramine
V = 100 mL
(b) Lidocaine

(c) Banana flavouring

2. Calculate the total volume
Chlorpheniramine = 100 mL
Lidocaine = 59
Banana flavouring = <u> 2.5 </u>
TOTAL = 162 mL
3. Calculate the number of doses

4. Calculate the number of days

-5 is on the left side of zero (negative) and 5 is on the right side of zero (positive). So, 5 is the answer...
6 and 7 is the correct answer
Answer:
option-c
Step-by-step explanation:
we are given

we will verify each options
option-A:
we can see that exponent is over 3
and it is positive and greater than 1
so, this function is increasing
so, this is FALSE
option-C:
At x=1:


At x=2:





So, it is getting tripled
so, this is TRUE
option-b:
we can plug x=0


so, this is FALSE
option-d:
we can plug x=1


so, this is FALSE
