Answer:

The answer is 9.

Step-by-step explanation:

3/2 is another way of saying 1.5 which is 100% + 50%. 50% of 6 is 3 so you just add 6 and 3 together and you get 9.

May be used to model radioactive decay. Q represents the quantity remaining after t years; k is the decay constant for plutonium

MArishka [77]

Answer:

The half life of the sample is 6301 years.

Step-by-step explanation:

The function used to model radioactive decay or exponential decay is,

$Q(t)=Q_0e^{-k\cdot t}$

Where,

Q(t) = Quantity after t time

Q₀ = Initial

k = decay constant

t = time period

As after an half life, the amount becomes half so,

$\Rightarrow \dfrac{Q_0}{2}=Q_0e^{-0.00011\cdot t}$

$\Rightarrow \dfrac{1}{2}=e^{-0.00011\cdot t}$

Taking natural log of both sides,

$\Rightarrow \ln \dfrac{1}{2}=\ln e^{-0.00011\cdot t}$

$\Rightarrow \ln \dfrac{1}{2}={-0.00011\cdot t}\times \ln e$

$\Rightarrow \ln \dfrac{1}{2}={-0.00011\cdot t}\times 1$

$\Rightarrow {-0.00011\cdot t}=\ln \dfrac{1}{2}$

$\Rightarrow t=\dfrac{\ln \dfrac{1}{2}}{-0.00011}$

$\Rightarrow t=6301.3\approx 6301\ years$

(No links or urls please) Write an equation of a circle that passes through the following points- see image

Sav [38]

Step-by-step explanation:

Step-by-step explanation:

The general equation for a circle is

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

where (h, k) is the coordinates of the center of the circle and r is the radius. Since the circle passes through (4, 4) and (-4, -4), its center is located at the origin, which means its equation becomes

${x}^{2} + {y}^{2} = {( \sqrt{ {4}^{2} + {4}^{2} } )}^{2} = 32$
