Use any method to solve the equation.if necessary, round to the nearest hundredth. 8x^2-48=0
dlinn [17]

Answer:

x = ± 2.45

Step-by-step explanation:

Given

8x² - 48 = 0 ( add 48 to both sides )

8x² = 48 ( divide both sides by 8 )

x² = 6 ( take the square root of both sides )

x = ± \sqrt{6} = ± 2.45 ( nearest hundredth )

A scientist left a 32-gram sample of a radioactive substance out and it was exposed to the air. After 30 minutes, only 26 grams
crimeas [40]

Answer:

There were 1.155 g of the substance eight hours later and it's halflife time is 1.66943 h.

Step-by-step explanation:

Since radiactive decay is expressed by a exponential function of the following kind:

mass(t) = mass(0)*e^(-a*t)

Where mass(t) is the mass of the substance at a given time, mass(0) is the inital mass substance, a is a factor that defines how fast the substance will decay and t is the elapsed time. The problem provided us with all the needed information to create the expression, with the exception of the "a". So we can apply it to the known point in order to determine "a". We have:

mass(0.5) = 32*e^(-a*0.5)

26 = 32*e^(-a*0.5)

e^(-0.5*a) = 26 / 32

e^(-0.5*a) = 0.8125

ln[e^(-0.5*a)] = ln(0.8125)

-0.5*a*ln(e) = ln(0.8125)

-0.5*a = ln(0.8125)

a = -ln(0.8125)/0.5 = 0.4152

So the expression that represents the mass of the substance over time is given by:

mass(t) = 32*e^(-0.4152*t)

After 8 hours we have:

mass(8) = 32*e^(-0.4152*8) = 32*e^(-3.3216) = 1.155 g

The half life is the time it'll take to reach half it's original mass, therefore:

16 = 32*e^(-0.4152*t)

32*e^(-0.4152*t) = 16

e^(-0.4152*t) = 16 / 32

e^(-0.4152*t) = 0.5

ln[e^(-0.4152*t)] = ln(0.5)

-0.4152*t = ln(0.5)

t = -ln(0.5)/0.4152 = 1.66943 h
