The statements that are true are:
A. The scenario can be represented by the function h(x) = –0.25(x)(x – 5).
E. The scenario can be represented by the function h(x) = –1(x – 5).
Given that the curve produced by the water from the hose has zeros at 0 and 5 and passes through the point (4, 1), determine which statements are true.
A. The scenario can be represented by the function h(x) = –0.25(x)(x – 5).
To check if this statement is true, substitute the given point (4, 1) into the equation:
h(4) = –0.25(4)(4 – 5) = –0.25(4)(-1) = 0.25(4)(1) = 1
Since h(4) evaluates to 1, which matches the y-coordinate of the given point, this statement is true.
B. The scenario can be represented by the function h(x) = (x)(x + 5).
This statement does not match the given information since the function does not account for the zeros at 0 and 5. Therefore, this statement is false.
C. The vertex is on the line x = 2.5.
Since the vertex is not mentioned or indicated by the given information, we cannot determine its exact location. Therefore, this statement is undetermined.
D. The greatest height that the water reaches is 1.5 units.
Since the given point (4, 1) lies on the curve, and no other information suggests a greater height, we cannot conclude that the greatest height reached is 1.5 units. Therefore, this statement is false.
E. The scenario can be represented by the function h(x) = –1(x – 5).
To check if this statement is true, let's substitute the given point (4, 1) into the equation:
h(4) = –1(4 – 5) = –1(-1) = 1
Since h(4) evaluates to 1, which matches the y-coordinate of the given point, this statement is true.
In summary, the statements that are true are:
A. The scenario can be represented by the function h(x) = –0.25(x)(x – 5).
E. The scenario can be represented by the function h(x) = –1(x – 5).

Suppose the population of a town is 15,200 and is growing 2% each year. Write an equation to model the population growth. Predict the population after 10 years
Answer:
The equation model is P = Po * e^rt
The population after 10 years = 18, 559 (most approximately)
Step-by-step explanation:
We use formula to find the population growth.
P = Po * e^rt
Where P is the total population after t years
Po is the initial population
r = rate of growth
t = time
e = 2.71 [Euler number]
The equation model is P = Po * e^rt
Now to find the population after 10 years, we have to plug in the given values in the formula.
Given:
Po = 15, 200, r = 2% = 2/100 = 0.02, and t = 10 years
P = 15,200*e^0.02(10)
P = 15,200*2.71^0.2
P = 15,200 *1.221
P = 18, 559
Therefore, the population after 10 years = 18, 559 (most approximately)
