Find the half life of a substance which decays according to the function A(t)=600e^-0.05t, where t is time in days. Round to the

Pavel [41]

Answer:

14 days

Step-by-step explanation:

The half life of a substance is the time required until the object has only half of the inicial mass.

So, to find the inicial mass of the object, we use t = 0 in the equation A(t):

A(0) = 600*e^0 = 600

Half of this mass is 300, so we can use A(t) = 300 and then find the time:

300 = 600e^-0.05t

e^-0.05t = 0.5

ln(e^-0.05t) = ln(0.5)

-0.05t = -0.6931

t = 13.862 days

Rounding to nearest day, we have that t = 14 days

Ted tossed a coin several times and recorded the number of heads and tails in the following table:

sineoko [7]

<h2>Answer:</h2>

Option: D is the correct answer.

D. 0.45

<h2>Step-by-step explanation:</h2>

The results of the experiment are given as follows:

Coin Experiment Side of Coin Number of Tosses

Heads 18

Tails 22

This means that total 40 experiments were performed.

( Since 18+22=40)

Also, the number of times head turn up=18

Hence, the experimental probability of getting heads is:

Ratio of number of times head turn up to the total number of experiments performed.

Hence,

$Probability=\dfrac{18}{40}\\\\\\Probability=0.45$

Hence, the experimental probability of getting head is:

0.45
