Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
where
---- because he doubles the amount each week
---->
substitute
therefore
This does represent an exponential function , because his savings increase by a constant rate
Answer:
Step-by-step explanation:
let the numbers at unit,ten and hundred place be x,y,z respectively,then number=100z+10y+x
also x=4z
y=z+5
and x+y+z=17
4z+z+5+z=17
6z=17-5=12
z=2
y=2+5=7
x=2×4=8
number=100×2+10×7+8=278
Answer: 0.42 mg
Step-by-step explanation:
Given : A 3mL unit dose of levalbuterol HCl contains 0.63mg of active ingredient.
Then , the amount of active ingredient in 1 ml dose of levalbuterol HCl =
Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl will be :-
Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl =0.42 mg
