Answer:
domain is (-∞,∞)
(-∞,0) U(0,∞)
Step-by-step explanation:
The domain is the set of x values for which the function is defined
In f(x) there is no restriction for x. the function is defined for all x values
so domain is (-∞,∞)
The domain is the set of x values for which the function is defined
when x=0, e^0=1 that makes the denominator 0
Denominator 0 is undefined. So x cannot be 0
domain is (-∞,0) U(0,∞)
We are given with the situation with the filling up of a ground backyards pool in time. The domain of the function is the x component or the abssisa of the points. The domain in this case is all positive real numbers because there is no negative amount of pol water and that all numbers including decimals and ll whole numbers are included. Answer is D.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the amount of iron, y represent the amount of potassium and z represent the amount of mulch.
Since the supplement weighs 16 lb, hence:
x + y + z = 16 (1)
Also supplement contains thirteen times as much mulch as iron. Therefore:
x = 13z
x - 13z = 0 (2)
The supplement also has twice as much potassium as iron, hence:
x = 2y
x - 2y = 0 (3)
solving equations 1, 2 and 3 simultaneously gives:
x = 10.1 lb, y = 5.1 lb, z = 0.8 lb
This means that the soil supplement contains 0.8 lb of mulch
Answer:
57 - 25y
Step-by-step explanation:
when 15 was distributed it should be '45 - 15y' instead of '45 + 15y'
