- i =

- Product rule of radicals: √ab = √a x √b
Firstly, factor out i: 
Next, apply the product rule of radicals here as such:

<u>Your answer is 5i√2, or the second option.</u>
Let the two integers be x and x+1
(x+1)^2-x^2=21
x^2+2x+1-x^2=21
2x+1=21
2x=20
x=10
then x=10, x+1
10+1=11
the two integers are 10, 11
Step-by-step explanation:
(i) From the graph value of x varies -3 to 3 i.e.

and domain in the input values which function can take
So, option (d) is correct.
(ii) option (d) is correct as it represent the function
. While all the other function does not satisfy the given conditions.
(iii)
are the parts of solution pair.
(iv) Option (c) and (d) represents the function as each element of the first set has a unique image in the second set.
Answer:
D. 1200 mg
Step-by-step explanation:
In order to find the solution we need to understand that a dosage of 20 mg/kg means that 20 mg are administered to the patient for each kg of his/her weight.
So, if the patient weight is 60 kg then:
Total drug X = (20mg/Kg)*(60Kg)=1200mg.
In conclusion, 1200 mg will be administered to the patient, so the answer is D.
