4. 0.192
5. 0.222
6. 0.262
Answer:
[tex]\ln (y) = 0.210x-2.601[/tex]
Step-by-step explanation:
Given table:
[tex]\begin{array}{|c|c|}\cline{1-2} \sf Length & \sf Diameter \\x & y\\\cline{1-2} \vphantom{\dfrac12} 2 & 0.113\\\cline{1-2} \vphantom{\dfrac12} 3& 0.151\\\cline{1-2} \vphantom{\dfrac12} 4& 0.192\\\cline{1-2} \vphantom{\dfrac12} 5& 0.222\\\cline{1-2} \vphantom{\dfrac12} 6& 0.262\\\cline{1-2} \end{array}[/tex]
To convert y = abˣ to linear form, take natural logs of both sides and rearrange:
[tex]\begin{aligned}y=ab^x \implies \ln y &= \ln ab^x\\\implies \ln y &= \ln a + \ln b^x\\\implies \ln y &= \ln a + x \ln b\\\implies \ln y &=x \ln b+ \ln a\end{aligned}[/tex]
This is in the straight-line form y = mx + c.
Substitute the first and last values of x and y from the table into the natural log formula:
[tex]\ln 0.113 = 2 \ln b+\ln a[/tex][tex]\ln 0.262 = 6 \ln b+\ln a[/tex]Subtract the first equation from the second equation to eliminate ln(a);
[tex]\implies \ln 0.262 - \ln 0.113 = 6 \ln b - 2 \ln b[/tex]
[tex]\implies \ln 0.262 - \ln 0.113 = 4 \ln b[/tex]
Apply the quotient log law:
[tex]\implies \ln \dfrac{0.262}{0.113} = 4\ln b[/tex]
Rearrange and solve for ln(b):
[tex]\implies \ln b = \dfrac{1}{4}\ln \dfrac{0.262}{0.113}[/tex]
[tex]\implies \ln b = 0.210\; \sf (3\;d.p.)[/tex]
Substitute the found value of ln(b) into one of the equations and solve for ln(a):
[tex]\implies \ln 0.262 = 6 \cdot \dfrac{1}{4}\ln \dfrac{0.262}{0.113}+\ln a[/tex]
[tex]\implies \ln a=\ln 0.262 -\dfrac{6}{4}\ln \dfrac{0.262}{0.113}[/tex]
[tex]\implies \ln a = -2.601\; \sf (3\;d.p.)[/tex]
Substitute the found values of ln(a) and ln(b) into the formula to create an equation for ln(y):
[tex]\boxed{\ln (y) = 0.210x-2.601}[/tex]
Tim has 42 marbles. He divides them equally into 7 bags. How many marbles are in each bag?
Answer:
6 marbles per bag
Step-by-step explanation:
42 marbles * 1 bag / 7 bags =
42 * 1/7 =
42/7 = 6 marbles per bag
1 bag represents each bag of the 7 total bags.
Multiply 1 bag / 7 bags with 42 marbles(total amount of marbles) to get the marbles in EACH bag.
Answer:
let x = marbles in a bag
x = 42/7
x = 6
There are 6 marbles in each bag for 7 bags(6) + (6) + (6) + (6) + (6) + (6) + (6)

The Solution for the given problem is 6x² +4x
What is Polynomial?
A polynomial is a mathematical statement made up of indeterminates and coefficients that solely includes the operations of addition, subtraction, multiplication, and positive-integer powers of variables.
Solution:
We are given with the values of the following terms f(x), g(x), and m(x)
f(x) = 3x² + 5x - z
g(x) = 5x² - 3x + z
m(x) = 2x² - 2x
To find: f(x) + [g(x) - m(x)]
so, we need to put the respective values in the equation and simplify it
3x² + 5x - z + [5x² - 3x + z - 2x² + 2x]
3x² + 5x - z + [3x² - x + z]

What is the equation for the line that passes through the points (3, 4) and (5,8)
The equation of a line is typically given in the form y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis). To find the equation of the line that passes through the points (3, 4) and (5, 8), we need to first calculate the slope of the line.
The slope of a line is given by the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of two points on the line. In this case, we have:
m = (8 - 4) / (5 - 3) = 4/2 = 2
Now that we know the slope of the line, we can use one of the given points to find the y-intercept. Let's use the point (3, 4). If we plug the values of x and y into the equation y = mx + b, we get:
4 = 2 * 3 + b
4 = 6 + b
-2 = b
Therefore, the equation of the line that passes through the points (3, 4) and (5, 8) is:
y = 2x - 2

5. A recent college graduate hopes to have $200,000 saved in their retirement account 25 years from now by contributing $150 per month in a 401(k) plan. The goal is to earn 10% annually on the monthly contribution. Will they have the $200,000 at the end of the 25 years?
Answer: No
Step-by-step explanation:
To determine whether the college graduate will have $200,000 saved in their retirement account after 25 years, we can use the formula for compound interest:
A = P * (1 + r/n)^(nt)
where A is the total amount of money in the account after the specified time, P is the initial amount of money deposited in the account, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years the money is invested.
In this case, the initial amount deposited each month is $150, the annual interest rate is 10%, the number of times the interest is compounded per year is 12 (once per month), and the number of years the money is invested is 25. Plugging these values into the formula above gives us:
A = $150 * (1 + 10%/12)^(12*25) = $150 * (1.0083)^300 = $150 * 3.4955 = $524.33
Since the goal is to have $200,000 saved in the account after 25 years, the college graduate will not have enough money in their account if they contribute $150 per month at 10% interest. In order to reach their goal, they would need to save more money each month or earn a higher interest rate on their contributions.

Answer:
The function g(x) = log(-3x - 9) - 1 is obtained from the parent function f(x) = log(x) through two transformations: a shift to the right and a shift downward. The shift to the right is achieved by multiplying x by -3 and subtracting 9, which results in a rightward shift in the function's graph. The shift downward is achieved by subtracting 1 from the final result, which results in a downward shift in the function's graph. These transformations result in a graph that is shifted to the right and downward compared to the graph of the parent function.

round 87388 to the nearest thousand
Answer:
To round a number to the nearest thousand, we first need to identify the thousands digit in the number. In this case, the thousands digit is 8, because 87388 is between 80000 and 90000.
To determine whether to round up or down, we need to look at the hundreds digit, which is 7 in this case. If the hundreds digit is 5 or greater, we round up. If the hundreds digit is less than 5, we round down. In this case, the hundreds digit is 7, which is greater than or equal to 5, so we need to round up.
To round up, we add 1000 to 87388, which gives us 88388. So, 87388 rounded to the nearest thousand is 88000.
Based on the relative frequency histogram below , which of the following statements is supported by the plot? i. The IQR of the distribution is roughly 10
ii. There are no outliers in the distribution.
iii. It is not possible to estimate the median without knowing the sample size. iv. The distribution is multimodal v. The mean of the distribution is smaller than its median.
The statement supported by the plot is that the IQR of the distribution is roughly 10. It is possible to estimate the median from the plot, and the distribution appears to be unimodal, with the mean being smaller than the median. There are no outliers shown in the plot.
The relative frequency histogram provides a visual representation of the distribution of the data. From the plot, it is possible to estimate the median, which is the middle value of the distribution, as well as the interquartile range (IQR), which is the difference between the upper and lower quartiles. The IQR of the distribution is roughly 10, which can be seen by the distance between the upper and lower quartiles in the plot. Additionally, the distribution appears to be unimodal, which means that it has only one mode or peak. It is also apparent that the mean of the distribution is smaller than its median, as the peak is shifted to the left of the median. Finally, there are no outliers shown in the plot, as all of the values appear to be within the range of the distribution.

the following sorting algorithm is stable and in runs in place. none of the others quicksort counting sort mergesort. true or false
A stable sorting algorithm is one that keeps the relative order of two equal elements. Quicksort is a sorting algorithm that has a high degree of instability, which means that it may alter the relative order of two equal components.
Which sorting algorithm is stable?The Merge Sort, Timsort, Counting Sort, Insertion Sort, and Bubble Sort are just a few examples of popular sorting algorithms that are by their very nature stable. Others, like Quicksort, Heapsort, and Selection Sort, are erratic. Stable sorting algorithms can be modified to be more efficient.
Because we swap elements according on the location of the pivot, QuickSort is an unstable algorithm (without considering their original positions). A sorting algorithm is said to sort in-place if it never stores more than a fixed number of input array members outside of the array. If the order of elements with the same value is not altered by a sorting technique, it is stable. Binary insertion sort is the only stable algorithm available from the options offered.
Therefore the correct answer is false.

How many positive integers have distinct prime digits?
Answer:
64
Step-by-step explanation:
There are 4 prime digits: 2, 3, 5, and 7.
If the number is one digit, there are 4 possible numbers.
If the number is two digits, there are 4(3)=12 possible numbers.
If the number is three digits, there are (4)(3)(2)=24 possible numbers.
If the number is four digits, there are (4)(3)(2)(1)=24 possible numbers.
Taking the sum, the answer is 64.
find the measure of m< VTK
Measure of angle VTK is 90°.
Define angle.Angles come in many different varieties in geometry. Angle is among the most crucial and fundamental units. Two rays or lines are linked at their shared terminus when they create an angle. We use angles in many facets of our daily lives, starting with the construction of buildings, dams, and monuments, not only in mathematics. The study of angles is essential to civil engineering. Two rays (half-lines) combined into an angle have a single terminal. The latter is known as the vertex of the angle, while the rays are known as its sides, occasionally as its legs, and occasionally as its arms.
