Mathematics

Answer:

​(fcircle◦​g)(x)  : -30x- 35.  domain: (-infinity, +infinity)

​(gcircle◦​f)(x) : -30x+ 50. domain: (-infinity, +infinity)

Step-by-step explanation:

The circle simply means to replace the x in the function with the other function. The domain is the x values. Since both of these equations are linear, it's negative infinity to infinity.

​(fcircle◦​g)(x): -10( 3x +5) +15

                    -30x -50 +15

                    -30x -35

​(gcircle◦​f)(x): 3(-10x +15) +5

                    -30x + 45 + 5

                    -30x +50

The client is to receive cyclophosphamide (Cytoxan) 50 mg/kg intravenously in divided doses over 5 days. The client weighs 176 p
marishachu [46]

Answer:

800 mg

Step-by-step explanation:

As the excerpt states that the client weights 176 pounds and is to receive cyclophosphamide (Cytoxan) 50 mg/kg, we have to convert 176 pounds to kg:

1 kg → 2.20 pounds

  x   ←  176 pounds

x= (176 pounds * 1 kg)/2.20 pounds= 80 kg

Now, we have to determine the total amount of cyclophosphamide (Cytoxan) that the client has to receive:

50 mg/kg

For 80 kg: 80 kg *50 mg/kg= 4,000  mg

As the dose is divided over 5 days:

4,000 mg / 5= 800 mg

The client will receive 800 mg of cyclophosphamide each day.

Solve the equation. Check your solution.
VladimirAG [237]
-5x/6  + 1=7/18
lowest common multiple=18
-15x+18=7
-15x=7-18
-15x=-11
x=-11/-15=11/15

The solution set is [11/15]

we check it out.
-5(11/15) /6    +  1 =7/18
(-55/15) / 6 +1=7/18
-55/90  +  1=7/18
(-55+90) /90=7/18
35/90=7/18
7/18=7/18
