The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of per day. Find t
jasenka [17]

Answer:

t = ln(0.5)/-r

Step-by-step explanation:

The decay rate parameter is missing. I will assume a value of 4% per day.

The exponential decay is modeled by the following equation:

A = A0*e^(-r*t)

where A is the mass after t time (in days), A0 is the initial mass and r is the rate (as a decimal).

At half-life A = A0/2, then:

A0/2 = A0*e^(-0.04*t)

0.5 = e^(-0.04*t)

ln(0.5) = -0.04*t

t = ln(0.5)/-0.04

t = 17.33 days

In general the half-life time is:

t = ln(0.5)/-r

Please help ASAP !!!!!
pochemuha

Answer:

(goh) (0) = 4

Step-by-step explanation:

Given that,

g(x) = 2x

h(x) = x² + 4

We need to find the value of (goh) (0).

Firstly we find (goh),

(goh) = g(h(x))

=g(x²+4)

(goh) (0) = 0²+4

=4

Hence, the required answer is 4.

Write the equation of the line that passes through the point (6,-2) and is parallel to the line y=1/3x+8
Dahasolnce [82]

If a line is parallel to another it has the same slope. Since the equation y = 1/3x +8 is parallel to the line we are trying to find, our second line will have the slope of 1/3x as well

This is the equation of a line:

y = mx + b

m = slope = 1/3x

b = y intercept = unknown

We have to find b to make this equation complete. How do we do this?

First plug what you know into the equation: y = 1/3x + b

Second we must solve for b. To do this plug a point that passes through the line (in this case they said (6, -2) passes through the line) into the x and y of the equation:

-2 = 1/3(6) + b

Now solve for b!

-2 = 6/3 + b

-2 = 2 + b

- 2 - 2 = b

-4 = b

The equation parallel to y=1/3x + 8 and passes through point (6, -2) is y = 1/3x - 4

The image below is the two line one a coordinate plane. As you can see, they are parallel to each other

Hope this helped!
