You need a common denominator while subtracting because really a fraction is a division problem and you cannot do 4/5-8/9 it does not make sense as for multiplication you really just multiplying everything that is why it makes sense.
Answer:
273 frogs.
Step-by-step explanation:
The equation of growth in the number of frogs N = 137(1.09)^t where t is the time in years.
The year 2022 is 8 years after 2014 so the prediction for N in 2022 is:
N = 137(1.09)^8 = 273.
Answer:
42
Step-by-step explanation:
simplify
Answer:
3v + 5u
Step-by-step explanation:
Write z = y^3 x^5 in terms of u and v.
Take the natural log (ln) of both sides. Then:
ln z = 3 ln y + 5 ln x
Substituting u for ln x and v for ln y, we get:
ln z = 3v + 5u (answer)
Yes it is. The statement is precise and reversible.
