Leander planted 100 acres with soybeans and he plans to increase his field size by 3% each year. What is the growth factor?
We are given that the rate of growth is:
[tex]0.03.[/tex]Now, recall that the growth factor is:
[tex]1+rate\text{ of growth.}[/tex]Therefore, the growth factor is:

The correct answer is option C.
[tex]\begin{gathered} yWe can see that the solution set is all above a dotted line, parallel to the x axis at height y = -3. Then, the inequality that respresents this is:[tex]y\ge-3[/tex]With this, we can already rule out option A.
Next, we can see a slanted dashed line, that when x = 0, y = 2. The solution set is below this line. The inequality that represnts this is:

What is a function?
Al-Biruni and Sharaf al-Din al-Tusi, two Persian mathematicians, are responsible for the first documented treatment of the concept of function. Initially, functions expressed the idealized interaction of two changing quantities. A planet's location, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity). The realms of application of the idea of a function were substantially expanded at the conclusion of the 19th century when it was defined in terms of set theory.

suppose that the amount of time it takes to build a highway varies directly with the length of the highway and inversely with the number of workers. suppose that it takes 100 workers 6 weeks to build 4 miles of Highway. how long will it take a 160 workers to build 16 miles of Highway?___weeks
Answer:
The amount of time it would take 160 workers to build 16 miles of Highway is;
[tex]15\text{ weeks}[/tex]Explanation:
Given that the amount of time it takes to build a highway varies directly with the length of the highway and inversely with the number of workers.
Let t represent the time in weeks, l represents the length of the highway in miles, and n represent the number of workers;
So, we have;

[18,-2]
[1,27]
[-4,0]
The range of the function will be equal to [-1, 27].
Function may be defined as an expression in which for every input variable there is only one output variable. The input variable is the variable x and also called as independent variable and output variable is the y variable and is also called as dependent variable. Domain of a function may be defined as the set of values of all the input values. Range of a function may be defined as the set of values of all the output values. For the domain -5 ≤ x < 3 we have function x² + 2. So, if we put -5 as x, we get the value equal to 27. Also, for the domain 3 ≤ x < 7 we have the function x - 4 and if we put the value 3 as x, we get the value equal to -1. Now, the range will be equal to [-1. 27].

The probability P10 for a data with mean of 198 and standard deviation of 74.5 is P10 = 25.15%
As per the question statement, a distribution of values is normal with a mean of 198 and a standard deviation of 74.5 and we are supposed to find P(10), which is the score separating the bottom 10% from the top 90%.
Given mean (µ) = 48.5 , SD(σ) = 18.2
z = (X - μ) / σ, where X = data
X = 216.74
z = (216.74 - 198) / 74.5 = 0.2515 or 25.15%
Hence the probability P10 for a data with mean of 198 and standard deviation of 74.5 is P10 = 25.15%

The length of the rectangle based on the information is 6/25 meters.
The length is 3/5 times more than the width.
How to calculate the length?From the information, the area of a rectangle is 3/5 square m² and the width is 2/5m. It should be noted that the length will be:
Length = Area / Width
Length = 3/5 ÷ 2/5
Length = 3/5 × 2/5
Length = 6/25
The length will s 6/25 meters.

Solve the system of functions, y2 = 3x and y = 7x.
We have the following system of functions:
[tex]\begin{gathered} y^2=3x \\ y=7x \end{gathered}[/tex]The second equation gives us an expression for y. We can replace y with these expression in the first equation:
[tex]\begin{gathered} y^2=(7x)^2=3x \\ 7^2\cdot x^2=3x \\ 49x^2=3x \end{gathered}[/tex]We can substract 3x from both sides:
[tex]\begin{gathered} 49x^2-3x=3x-3x \\ 49x^2-3x=0 \end{gathered}[/tex]The x is a factor of both terms on the left. Then we can rewrite this equation:
[tex]\begin{gathered} 49x^{2}-3x=0 \\ x(49x-3)=0 \end{gathered}[/tex]So we have that the product of two terms is equal to 0. This happens when any of them is equal to 0 so we have two equations:
[tex]\begin{gathered} x=0 \\ 49x-3=0 \end{gathered}[/tex]From the first we have x=0 and we can add 3 to both sides of the second equation:
[tex]\begin{gathered} 49x-3+3=0+3 \\ 49x=3 \end{gathered}[/tex]Then we divide both sides by 49:
[tex]\begin{gathered} \frac{49x}{49}=\frac{3}{49} \\ x=\frac{3}{49} \end{gathered}[/tex]So we have the two x-values of the solutions: x=0 and x=3/49. In order to find their respective y-values we can use any of the two original functions:
[tex]\begin{gathered} y=7x\rightarrow y=7\cdot0=0\rightarrow(x,y)=(0,0) \\ y=7x\rightarrow y=7\cdot\frac{3}{49}=\frac{21}{49}\rightarrow(x,y)=(\frac{3}{49},\frac{21}{49}) \end{gathered}[/tex]AnswerWe have two solutions: (0,0) and (3/49,21/49). We can round the values of the second solution:
[tex]\begin{gathered} \frac{3}{49}\cong0.06 \\ \frac{21}{49}\cong0.43 \end{gathered}[/tex]Then the solutions are (0,0) and (0.06,0.43). Then the answer is the fourth option.

What is the simplified expression for 2 power 2 multiplied by 2 power 3 over 2 power 4?
A) 2 power 0
B) 2 power 1
C) 2 power 2
D) 2 power 3
Answer:
[tex]2^1[/tex]
Step-by-step explanation:
Hello! So, to tackle this problem let's start off with writing out the formula as such! [tex]\frac{2^2 * 2^3}{2^4}[/tex]
To solve this, what we can do is start off by isolating [tex]\frac{2^2}{2^4}[/tex] (we can worry about [tex]2^3[/tex] later). To evaluate [tex]\frac{2^2}{2^4}[/tex], we're essentially just simplifying the fraction and reducing the exponents. In this case, we can reduce the power of 2 from both the numerator and denominator to get [tex]\frac{1}{2^2}[/tex] (this is obtained by dividing both numerator and denominator by [tex]2^2[/tex])
Once we have that, we are now essentially left with [tex]\frac{2^3}{2^2}[/tex]! From here, we can apply exponent rule, which allows us to get rid of the denominator entirely and now it becomes 2^(3-2). We can subtract the numbers to then simplify it into our answer, [tex]2^1[/tex] or in other words just 2!
