Ying is a professional deep water free diver. His altitude (in meters relative to sea level), xxx seconds after diving, is model

Wewaii [24]

Answer:

60 seconds

Step-by-step explanation:

$D(x) = \dfrac{1}{36}(x-60)^2-100$

When Ying reaches his lowest altitude, his velocity is 0.

The velocity, v(x) is the tiome-derivative of D(x).

$v(x) = \dfrac{d}{dx}D(x)$

$v(x) = \dfrac{2}{36}(x-60)\times1 = \dfrac{x-60}{18}$ (This was done by using chain rule)

Equating v(x) to 0,

$\dfrac{x-60}{18} = 0$

$x - 60 = 0$

$x = 60$

luda_lava [24]

Answer: C

Step-by-step explanation:

This describes an expotential function

At t = 0, P = 70

Therefore, C = 70

P = 70 e^kt

Solve for k by plugging in (4,360)

k = 0.4094

plug in t(7 hours)

70 e^(0.4094*7)

The answer roughly equals C

Find the derivative of f(x) = 6x + 2 at x = 1.

earnstyle [38]

$f'(x_0)=\lim\limits_{x\to x_0}\dfrac{f(x)-f(x_0)}{x-x_0}\\\\f(x)=6x+2;\ x_0=1\\\\f'(1)=\lim\limits_{x\to x_0}\dfrac{(6x+2)-(6\cdot1+2)}{x-1}=\lim\limits_{x\to x_0}\dfrac{6x+2-8}{x-1}\\\\=\lim\limits_{x\to x_0}\dfrac{6x-6}{x-1}=\lim\limits_{x\to x_0}\dfrac{6(x-1)}{x-1}=\lim\limits_{x\to x_0}6=6\\\\\\Answer:\boxed{f'(1)=6}$
