After the consumption of an alcoholic beverage, the concentration of alcohol in the bloodstream (blood alcohol concentration, or

bezimeni [28]

Answer:

about 0.177 mg/mL

Step-by-step explanation:

The maximum is found where the derivative of C(t) is zero.

dC/dt = 1.35e^(-2.802t) -(1.35t)2.802e^(-2.802t) = 0

Solving for t gives ...

t = 1/2.802

So, the maximum C(t) is ...

C(1/2.802) = 1.35/2.802e^(-1) ≈ 0.177 . . . . . mg/mL

The maximum average BAC during the first 6 hours is about 0.177 mg/mL.

_____

The maximum occurs about 21 minutes 25 seconds after consumption.

The equation of a circle C, with centre O, is:

Nataliya [291]

Answer:

a) The center coordinates O is (0,0)

b) The radius C = 15

Step-by-step explanation:

The given equation of the circle is : $x^{2} + y^{2} = 225$

Now, general form of the equation of the circle is:

$(x-h)^{2} + (y - k)^{2} = r^{2}$

where (h,k) are the center co -ordinates and r is the radius of the circle.

Comparing the general equation with the given equation, we get

$(x-0)^{2} + (y - 0)^{2} = (15)^{2}$

So, here the center coordinates (h,k) = (0,0)

And the radius of the given circle is r = 15

Find the value of x 12 5 X

steposvetlana [31]

Answer:

x = 13

Step-by-step explanation:

Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.

Set the equation:

a² + b² = c²

let:

a = 5

b = 12

c = x

Plug in the corresponding numbers (& x) to the corresponding variables:

(5)² + (12)² = (x)²

Simplify. First, solve for the power, and then add:

x² = (5²) + (12²)

x² = (5 * 5) + (12 * 12)

x² = 25 + 144

x² = 169

Next, root both sides of the equation:

√x² = √169

x = √169 = √(13 * 13) = 13

x = 13

Note the rules, and it should be easier:

30-60-90° = 1 , √3 , 2

45-45-90° = 1 , 1 , √2

Any other measurements use the equation: a² + b² = c²
