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.

Thomas has $6.35 in dimes and quarters. The number of dimes is three more than three times the number of quarters. How many quar

Misha Larkins [42]

q = quarters

dimes is 3 plus 3times quarters

so 3q is 3 times quarters

so 3q+3 would be 3 times plus 3

equation is 3q+3

the value would be 10(3q+3)

Use the definition of the derviative to compute the derivative of f(x)= 1- 7x^2 at the specific point x=2.

GaryK [48]

Answer:

$f'(x) = -28 \ at \ x = 2$

Step-by-step explanation:

$f'(2) = \lim_{h \to 0}\frac{f(2+h)) -f(2)}{h} \\\\f(2+h) = 1 - 7(2+h)^2 = 1 - 7(4 +h^2 +4h) = 1 - 28 - 7h^2 - 28h = - 7h^2 -28h - 27\\\\f(2) = 1 - 7(2^2) = 1 - 28 = -27\\\\f(2+h) - f(2) = -7h^2 - 28h - 27 - (-27) = -7h^2 -28h -27 + 27 = -7h^2 -28h\\\\f'(2) = \lim_{h \to 0}\frac{-7h^2 - 28h}{h} \\\\$

$= \lim_{h \to 0} \frac{h(-7h -28)}{h}\\\\= \lim_{h \to 0} (-7h -28)}\\\\= -7 (0) - 28\\\\= -28$
