Answer:
Step-by-step explanation:
2 over 3 to the power of 2 + 5 × 2 − 4
The answer is 32.
You essentially multiply 2 by itself 5 times.
The vertex being given makes your life a whole lot easier. The equation is
y = a(x - 1)^2 + 3. That's what you have so far. You have enough information to solve for a. when x = 2, y = 6. So put those values into the equation and solve for a
6 = a(2 - 1)^2 + 3 Subtract 3 from both sides.
6 - 3 = a(2 -1)^2 Combine the brackets.
3 = a (1)^2
3 = a (1) Divide by 1
3/1 = a
a = 3
Now put that into the equation you started out with.
y = 3(x - 1)^2 + 3

The answer to this question is 7/10
Answer:
90 hours
Step-by-step explanation:
The rate at which water enters the pool is
75 gallons
-------------------
1 hour
This is equivalent to
1 hour per 75 gallons, leading to:
1 hour
-------------------- * 6,750 gallons = 90 hours
75 gallons
