Answer:
x < 0
Step-by-step explanation:
If you were to graph the function, you would get a parabola that opens down with the vertex at (0, 0). So, the graph is increasing from -∞ to 0.
Answer:
3*10^3
Step-by-step explanation:
4.8(10^9)/1.6(10^3)
we can split this equation into
4.8/1.6 * 10^9/10^3
= 3*10^3
Answer:
149
Step-by-step explanation:
Answer:

20 gallons of water is leaked after an hour.
Step-by-step explanation:
Water is leaking at a constant rate of 1/3 gallon per minute.
a) We have to write a linear equation in two variables that show the amount of water, w, in gallons, that is leaked from the faucet after t minutes.
So, the equation is
......... (1) (Answer)
b) Now, if t = 1 hour i.e. 60 minutes, then from equation (1) we can write
gallons.
Therefore, 20 gallons of water is leaked after an hour. (Answer)
Answer:
1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e.
is the same
as taking the square root.
- so
is the same as the square root of
.
For example, taking the square root of 4 will determine:





so the expression becomes


∵ 
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.
