Expand and Combine like terms: <br> (4t^3-5)^2

arsen [322]

Answer: 16t^6−40t^3+25 is the answer

first lets set the equation as a binomial *remember 2 binomial= trinomial*

so its going to look something like..........

(4t^3-5) (4t^3-5)

now we do the foil method so 4t^3* 4t^3= 16t^6 (add exponents)

do the same for the other terms:

4t^3*-5= -20t^3

-5*4t^3= -20t^3

-5*-5= 25

now the whole equation is...

16t^6-20t^3-20t^3+25 (combine like terms like -20t^3 and -20t^3)

therefor the answer is... 16t^6-40t^3+25

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed

kipiarov [429]

Answer:

You inject 60.9628 milliliters of dosage

Step-by-step explanation:

1 pound = 0.453592kg,

Patient's weight in pounds = 168

Patient's weight in kg = $76.2035 kg$

Now we are given that The dosage is 0.4 mg per kilogram of bod

So, dosage = $0.4 \times 76.2035 mg = 30.4814 mg$

1 microgram = 0.001 mg

Concentration of drug = $500 micrograms/ml = 500 * 0.001 mg/ml = 0.5 mg/ml$

Now we are supposed to find How many milliliters (= cc) are you to inject?

So,milliliters of dosage required to inject = $\frac{30.4814}{0.5} = 60.9628$

Hence you inject 60.9628 milliliters of dosage
