Hello :)
The question is asking about true statements, so let's go through the choices.
A) The profit increased for all five months; this question means that the profit (money value) should have increased every month; while it does from June to September, October goes down so this statement is false.
B) This statement is saying June + 100,000 dollars+ =August. June's profit is approximately 150,000 lower than August so this is true.
C) This answer choice explains October's profit was less than June's; 298,000 from October is bigger than 248,000 from June so this is false.
D) I can't read off the last statement but no profit is drastically bigger than the other for it to be twice as much of September.
Answer:

Step-by-step explanation:
The function that could model this periodic phenomenon will be of the form

The tide varies between 3ft and 9ft, which means its amplitude
is

and its midline
is
.
Furthermore, since at
the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is
.
The period of the full cycle is 14 hours, which means


giving us

With all of the values of the variables in place, the function modeling the situation now becomes

Answer: 
Step-by-step explanation:
1. You have the following phrase given in the problem: 16 times as many books. You can conclude this is a multiplication word problem, because:
- Let's call
the number of books.
- "As many boooks" indicates multiplication.
- 16 times means that
should be multiplied by 16.
2. Then, you can conclude that the expression that best represent the phrase is:

Answer:
31m/s
Step-by-step explanation:
Using the equation of motion
v² = u² + 2gH
H is the height of fall = 49m
g is the acceleration due to gravity = 9.8m/s²
u is the initial velocity = 0m/s
v² = 0² + 2(9.8)(49)
v² = 960.4
v = √960.4
v = 30.9m/s
v ≈ 31m/s
Hence the velocity of water at the turbine is 31m/s
