fermium-253 has a half-life of three days. a sample contains 400 g. how long will it take for the sample to decay to 100 g?

2 answers:

6 0

This is a relatively easy half life calculation.
After one half-life period, half of the isotope remains.
After two half-life periods, one quarter of the isotope remains.
That being the case, we see this will take 2 half-life periods or 6 days.

Haley pays a monthly fee of $20 for her cell phone and then pays 5 cents per minute used. The cost of Haley’s cell phone bill ca

Svet_ta [14]

The domain is
{x | x >=0}
Or simply [0, infinity)
Since Haley can not use any negative minutes.

The range is
{y | y >=20}
Or simply [20, infinity)
This is because if Haley doesn't use any minutes, the price will stay at $20.
Let me know if you have any questions.

The isosceles triangle has a base that measures 14 units. The value of y, the length of each leg, must be equal to 7. between 7

Dvinal [7]

1.The isosceles triangle has sides of length 14, y, y

2. According to the "triangle inequality" :

y+y>14
2y>14
y>14/2=7

(y is greater than 7)

3. Remark, check the figures:

the side lengths cannot be less than (neither equal to 7), because we cannot get a triangle in that case, check picture 2

In picture 1 wee see that the side lengths can be as large as we want. We can erect an altitude, as high as we want. Pick a point on the altitude, and join it to the endpoints of the base, and we get an isosceles triangle with base equal to 14.
