Half life = 1250 years
Start amount = 36
End amount = 15
Time = ?

15 = 36 * (1/2)^(x/1250)
0.417 = (1/2)^(x/1250)
ln(0.417) = x/1250 * ln(1/2)
x = 1577.95 years

What does y equal ??!?!
garik1379 [7]
<h3>Answer:  658.3</h3>

==================================================

Explanation:

The adjacent complementary angle to that 28 degree angle is 62 degrees because 62+28 = 90.

If the reference angle is the upper acute angle 62 degrees, then the y is the opposite leg and the side 350 is the adjacent leg.

Use the tangent ratio

tan(angle) = opposite/adjacent

tan(62) = y/350

350*tan(62) = y

y = 350*tan(62)

y = 658.254262871217

y = 658.3
