Approximate 5.824 to the nearest whole

The nearest whole is 6.

Step-by-step explanation:

We are going to round each number.

We know the rule if it is under 5, we do not make the number change. If it is above 5, the number changes. For this one, we do not have to round the hundredths or thousandths. We do round the 8, though. The nearest whole to 5.8 is 6, since 8 is above 5 and that means it is closer to 6 rather than 5.

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
