Answer:
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = 
km/min
Time taken up the hill = 
minutes
Speed of Wilmer down the hill = 
km/min
Time taken up the hill = 
minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
Distance up the hill = 
Distance down the hill = 
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
The correct answer is x = 20
Tangent (25) = opp / adj = 42 / horizontal distance
horizontal distance = 42 / tangent (25)
horizontal distance = 42 / 0.46631
horizontal distance =

Answer:
the equation should be corrected to fit the data of the problem. With the corrected equation a mass of 0.5 grams remains after 150 years
Step-by-step explanation:
for the mass y( in grams)
y=23* (1/2)^(t/45), t ≥ 0.
the initial mass is at t=0 , then
y= 23 grams → should be 16 grams
half-life from the equation = 45 years → should be 30 years
the correct equation should be
y=16*(1/2)^(t/30), t ≥ 0
then after 150 years → t= 150
y=16*(1/2)^(150/30)= 16*(1/2)^5 = 16/32 = 0.5 grams
then a mass of 0.5 grams remains after 150 years
