A radioactive material is an element that is highly unstable due to its high neutron-to-proton ratio. Because of this, they spontaneously undergo nuclear reaction under nuclear fission releasing subparticles. The time it took to consume half of the original amount of the radioactive material is called the half-life.

The equation is <span>a2=ae^(−9.753t), where a2 is the concentration after time t and a is the original concentration. The ratio of a2/a should be 0.5/1 or 1/2. Therefore,
a2/a = e^(-9.753t)
0.5 = e^(-9.753t)
ln(0.5) = lne^(-9.753t)
ln(0.5) = -9.753t
t = 0.071 days or 1.7 hours.

If m∠W = 105° and m∠Y = 75°, then m∠X = <br><br> Please show your work, so I know the process.
Paha777 [63]

Answer:

30°

Step-by-step explanation:

First we must know that the sum of the interior angles of a triangle sum up to 180°.  Furthermore, a straight line is also 180°.  By using these what we know we can determine what the value of m∠X is.

First we know that m∠W and m∠Z make up a straight line, since m∠W is 105° it follows that:

180° = m∠W + m∠Z

And so:

m∠Z = 180° - m∠W = 180°-105° = 75°

m∠Z = 75°

Now, we also know that the sum of m∠X + m∠Y + m∠Z = 180° and so:

m∠X = 180° - m∠Y - m∠Z

m∠X = 180° - 75° - 75° = 30°

Therefore, m∠X = 30°

For the equation y = 7x – 2, what is the rate of change? What does it mean? EXPLAIN YOUR ANSWER IN SIMPLE TERMS PLEASE!
Andrei [34K]

Answer:

slope is 7

Step-by-step explanation:

the rate of change is the slope

in the general equation y = mx + b

x and y are point coordinates (x,y)

b is the y intercept

m is the slope

this is the rate at which the points are changing essentially

a larger slope will produce a steeper line

a negative slope will produce a line pointed downward

a smaller slope will produce a flatter line
