The fish population in a local lake is 10,000. The population increase by half every year. Which function represents the fish population after x years?
1. f(x) = 1.5(10,000)^x
2. 10,000(-1.5)^x
3. None
4. f(x) = 10,000(0.5)^x
5. f(x) = 10,000 (1.5)^x
Answer:
5. f(x) = 10,000 (1.5)^x
Step-by-step explanation:
We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test it.
Initial:
10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
Let's try our equation.
f(x) = 10,000 (1.5)^x
x = 2
10,000(1.5)^2
10,000(2.25) = 22,500
The same!

Write 5.4 as a mixed number and as an improper fraction.
Write your answer in simplest form.
Answer:
27 over 5 improper fraction
5 whole number 2 over 55 mixed
Do you want to know how to write the decimal number 5.4 as a fraction?
Here we will show you step-by-step how to convert 5.4 so you can write it as a fraction.
You can take any number, such as 5.4, and write a 1 as the denominator to make it a fraction and keep the same value, like this:
5.4 / 1
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 5.4, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.
Therefore, in this case we multiply the numerator and denominator by 10 to get the following fraction:
54 / 10
Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.
The GCD of 54 and 10 is 2. When we divide the numerator and denominator by 2, we get the following:
27 / 5
Therefore, 5.4 as a fraction is as follows:
27 / 5

If the original lengths of the graph below are multiplied by 3, will the new drawing be a reduction or enlargement?
Answer:
enlargement
Step-by-step explanation:
On a coordinate plane, a straight red line with a positive slope, labeled g of x, crosses the x-axis at (negative 3, 0) and the y-axis at (0, 3). A straight blue line with a positive slope, labeled f of x, crosses the y-axis at (0, negative 3) and the x-axis at (1, 0). Both lines intersect at (3, 6).
Which statement is true regarding the functions on the graph?
f(6) = g(3)
f(3) = g(3)
f(3) = g(6)
f(6) = g(6)
Answer:
f(3)=g(6)
Step-by-step explanation:
The statement is true regarding the functions on the graph is f of 3=g of 3. The correct option is B.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given two function f(x) and g(x) which intersect at (3, 6).
Now, when two functions intersect then it means that there is a value of x for which the value of both the functions is equal. This value of x and y is the point at which the two functions intersect.
Hence, the statement is true regarding the functions on the graph being
f of 3=g of 3.

Rhone purchases eggs from a local dairy farm. He finds 3 broken eggs. He uses half the remaining eggs to bake a few pancakes. If 5 eggs remain now, how many eggs did Rhone purchase from the farm?
Answer:
He bought 13 eggs
Step-by-step explanation:
Lets make a equation:
X-3 /2=5
That means 5 times 2+3 would be X. 5 times 2=10 plus 3=13
The required number of eggs that Rhone purchased is given as 13.
Given that, Rhone purchases eggs from a local dairy farm. He finds 3 broken eggs. He uses half the remaining eggs to bake a few pancakes, at the end, 5 eggs remain now, how many eggs did Rhone purchase from the farm is to be determined.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let the number of eggs be x,
Now,
3 eggs were found broken, the remaining eggs = x - 3,
He uses half the remaining eggs to bake a few pancakes and 5 eggs were left,
So,
X-3 /2=5
x = 10 + 3
x = 13
Thus, the required number of eggs that Rhone purchased is given as 13.

Is this a function or non function?
Answer:
yes it is a function
Step-by-step explanation:
A function can only cross the y-axis once. If it crosses any y-axis more than once, it is not a function. This starts at 0 and will continue on to positive infinity. It will never cross the same y-axis twice. So yes, it is a function.
Choose the slope and y-intercept that correspond with the graph.
Answer:
Slope=3
y-intercept=4
Step-by-step explanation:
the line intercepts the y axis at 4.
Answer:
slope = 3
y-intercept = 4
Step-by-step explanation:
From the graph, we can automatically tell that the y-intercept is at (0,4) so the y-intercept is 4. Now, we just need to find the slope and to do that we can choose 2 points. I am choosing (-2,-2) and (0,4).
The slope formula is m = y2-y1/x2-x1. I am going to plug in the points in the formula.
m = (4 - (-2))/(0 - (-2))
m = 6/2
m = 3
slope = 3
y-intercept = 4

The perimeter of the surface of a workbook is 40 inches. The workbook is 11 inches tall. How wide is it?
Answer:
9 inches
Step-by-step explanation:
11 times two for the two equal sides is 22. 40-22 equals 18. 18 is the sum of the other two sides so you divide by two. 18/2 equals 9, so 9 inches.
The area of the base of a square notepad is 2.25 square inches. What is the length of one side of the base of the notepad?
Answer:
1.5 inches
Step-by-step explanation:
Because the base of the notepad is a square, that means that each side of the base would be equal. Since the area is 2.25 square inches, and each side would have to be equal, the equation to solve would be x*x = 2.25, or x^2=2.25. So, you just take the square root of both sides, and x=1.5 inches. Each side of the notepad would be 1.5 inches.
Answer: 1.5 inches
