The average blood alcohol concentration (bac) of eight male subjects was measured after consumption of 15 ml of ethanol (corresp

Neporo4naja [7]

Answer:

After 5 minutes, the BAC was increasing at the rate of 0.0137 mg/mL a minute.

Step-by-step explanation:

The average blood alcohol concentration (bac) is modeled by the following function.

$c(t) = 0.0225te^{-0.0467t}$

In which t is measured in minuted.

How rapidly was the BAC increasing after 5 minutes?

This is c'(t) when t = 5.

Using the derivative of the product.

Derivative of the product:

$c(t) = f(t)*g(t)$

$c'(t) = f'(t)*g(t) + f(t)*g'(t)$

In which problem:

$f(t) = 0.0225t$

$g(t) = e^{-0.0467t}$

$c'(t) = 0.0225e^{-0.0467t} - 0.0225*0.0467*te^{-0.0467t}$

$c'(5) = 0.0225e^{-0.0467*5} - 0.0225*0.0467*5e^{-0.0467*5} = 0.0137$

After 5 minutes, the BAC was increasing at the rate of 0.0137 mg/mL a minute.

Which of the following is a point of tangency on the circle below? Help ASAP please

kumpel [21]

Answer:

Point B

Step-by-step explanation:

a point of tangency on a circle is where an outside line touches the outer circle at one point (the outside line touching it only once is what makes that line a tangent) so in this case the point of tangency is Point B

Josh can split a truckload of logs in 8 hours, but working with his dad, they can get it done in 3 hours. How long would it take

grin007 [14]

Answer: 4.8 hrs

Step-by-step explanation:

Josh: $\frac{1}{8}$

Dad: $\frac{1}{x}$

Together: $\frac{1}{3}$

Josh + Dad = Together

$\frac{1}{8}$ + $\frac{1}{x}$ = $\frac{1}{3}$

$\frac{1}{8}*(24x)$ + $\frac{1}{x}*(24x)$ = $\frac{1}{3}$ (24x)

3x + 24 = 8x

-3x -3x

24 = 5x

÷5 ÷5

4.8 = x
