A radio active isotope decays according to the exponential decay equation where t is in days. Round to the thousandths place. Th

Whitepunk [10]

To calculate the value of the half life we proceed as follows;
a/2=ae^(-2.360t)
the a(s) will cancel and we shall remain with:
1/2=e^-2.360t
introducing the natural logs we get:
ln (1/2)=ln e^(-2.360t)
ln(1/2)=-2.360t
hence;
t=(ln 0.5)/(-2.360)
t=0.294
the answer is t=0.294

If Angle A = 5x-10, find the value(s) for x that would ensure that Angle A was an obtuse angle.

morpeh [17]

Answer:

20 < x < 38.

Step-by-step explanation:

An obtuse angle has a value between 90 and 180.

90 < 5x - 10 < 180

5x - 10 > 90

5x > 100.

x > 20.
