A certain medication is eliminated from the bloodstream at a rate of about 17% per
aivan3 [116]

Using an exponential function, it is found that the multiplier used to predict the amount of medication remaining 2 hours after the peak level is of 0.6889.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, we have that the decay rate is of r = 0.17, hence:

A(t) = A(0)(0.83)^t

After 2 hours, the multiplier is given by:

A(2) = A(0)(0.83)^2 = 0.6889A(0)

If the line joining (3x, x+1) and (11,12) has a slope of 4 what is the value of x​
Irina18 [472]

Answer:

x = 3

Step-by-step explanation:

(3x,\: x +1)=(x_1, \:y_1)

(11,\: 12)=(x_2, \:y_2)

slope =  \frac{y_2 - y_1}{x_2 - x_1} \\  \\ 4 =  \frac{12 - (x + 1)}{11 - 3x}   \\  \\ 4 =  \frac{12 - x  -  1}{11 - 3x}   \\  \\ 4 =  \frac{11 - x}{11 - 3x}   \\  \\ 4(11 - 3x) = 11 - x \\  \\ 44 - 12x = 11 - x \\  \\ 44 - 11 = 12x - x \\  \\ 33 = 11x \\  \\ x =  \frac{33}{11}  \\  \\  \huge \red{ \boxed{x = 3}}
