Answer:
u ≈ 5.7
Step-by-step explanation:
Using the Sine rule in Δ TUV, that is
=
, substitute values
=
( cross- multiply )
u × sin26° = 2.5 × sin85° ( divide both sides by sin26° )
u =
≈ 5.7 ( to 1 dec. place )
-2f(x) means it is reflected and has a negative slope.
and for the 2 it means that the graph is compressed horizontally by factors of units
if it's less than 2 it would have been stretched, but since it's greater than 1 it is compressed.

Answer:
It will take 50 years to decay from 512 grams to 121.5 grams.
Step-by-step explanation:
The decay formula :

where
N= amount of substance after t time
N₀= initial of substance
t= time.
A substance decays at a rate 25% every 10 years.
So, remaining amount of the substance is = (100%-25%)= 75%
, t= 10



Taking ln both sides



Now , N₀= 512 grams, N= 121.5 grams, t=?




Taking ln both sides




⇒t=50 years
It will take 50 years to decay from 512 grams to 121.5 grams.
