Answer:
5.1 days
Step-by-step explanation:
Given in the question,
initial amount of substance = 34 grams
k-value = 0.137
To find the half life of this substance we will use following formula
here N(0) is initial amount of substance
t is time in days
Plug values in the formula
1/2 = e^{-0.137t}
Take logarithm on both sides
ln(1/2) = ln( e^{-0.137t})
ln(1/2) = -0.137t
t = ln(1/2) / -0.137
t = 5.059
t ≈ 5.1 days (nearest to tenths)
Check out the attached image. I drew what I think your book is showing. The figure on the left is triangle ABC without any extended segments. The figure on the right has segment AB extended shown in red. This forms the exterior angle x
The rule that connects x, y and z together is the remote interior angle theorem. It says that adding two interior angles is going to be equal to the exterior angle that is not touching either interior angle. The "remote" part means "far away" so just think of the two angles that are furthest way or not touching the exterior angle in question.
In terms of algebra, the rule is
x+y = z
Subtract 4 from both sides
y−4≤−2x
Divide both sides by −2
- y-4/2 ≥ x
Switch sides

Answer:
13 units
Step-by-step explanation:
Im doin this in class to so i got you
the equation would be d=(8-(-5))2-(-3-(-2))2
Next solve in the parenthesis 13 power of 2 +-1 power of 2
Then do the powers 169+1
d=170
Then you square 170 which is 13.03840481
That simplifies to 13
yayyyy
