Answer:

D. Cos(Z) = \frac{5}{13}

Step-by-step explanation:

Using trigonometric ratios formula, thus:

Cos(Z) = \frac{Adjacent}{Hypotenuse}

Reference angle = Z

Adjacent = 10

Hypotenuse = 26

Plug in the values into the formula

Cos(Z) = \frac{10}{26}

Simplify

Cos(Z) = \frac{5}{13}

Sophia has an ear infection. The doctor prescribes a course of antibiotics. Sophia is told to take 500 mg doses of the antibioti
julsineya [31]

Answer:

see below

Step-by-step explanation:

Dosage= 500 mg

Frequency= twice a day (every 12 hours)

Duration= 10 days

Number of dosage= 10*2= 20

residual drug amount after each dosage= 4.5%

We can build an equation to calculate residual drug amount:

d= 500*(4.5/100)*t= 22.5t, where d- is residual drug, t is number of dosage

After first dose residual drug amount is:

  • d= 500*0.045= 22.5 mg

After second dose:

  • d= 22.5*2= 45 mg

As per the equation, the higher the t, the greater the residual drug amount in the body.

Maximum residual drug will be in the body:

  • d= 20*22.5= 450 mg at the end of 10 days

Maximum drug will be in the body right after the last dose, when the amount will be:

  • 500+19*22.5= 927.5 mg
