A travel guide has dimensions 8 in. by 10 in. What scale factor should be used to make an enlarged version that has dimensions 12 in. by 15 in.
The scale factor for the length is 12/8 = 1.5 and the scale factor for the width is 15/10 = 1.5
So the scale factor used to make an enlarged version is 1.5.
What is the scale factor?A scale factor is a value used to multiply the dimensions of an object in order to increase or decrease its size. It is often represented as a ratio, such as 1:2 or 1/2, which indicates that the new object is half the size of the original object. Scale factors can also be expressed as a decimal or a percentage, such as 0.5 or 50%. Scale factors can be used in various fields such as architecture, cartography, and graphic design.

What is the midpoint of f/x )=( x 2 )( x 4?
The midpoint of the x-intercepts of f(x) = (x - 2)(x - 4) is (3, 0).
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
A compass and straightedge setup can be used to locate the midpoint of the line segment they determine given two points of interest. By initially building a lens out of circular arcs with equal radii centered at the two endpoints and joining the cusps of the lens, one can determine the midpoint of a line segment immersed in a plane. The midpoint of the segment is then the place where the line joining the cusps intersects the segment.

$710 is invested in an account earning 3.7% interest (APR), compounded monthly. Write a function showing the value of the account after tt years, where the annual growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year (APY), to the nearest hundredth of a percent.
The function for the amount after {t} years can be written as -
[tex]$710(1 + 0.45/12nt)^{nt}[/tex]
What is compound interest?Compound interest is the addition of interest to the principal sum of a loan or deposit. Mathematically -
[tex]$A = P(1 + \frac{r}{n})^{nt}[/tex]
where -
[A] = final amount
[P] = initial principal balance
[r] = interest rate
[n] = number of times interest applied per time period
[t] = number of time periods elapse
Given is that $710 is invested in an account earning 3.7% interest (APR), compounded monthly.
We can write -
A = 710(1 + 0.37/12)¹²⁽¹⁾
A = 710(1 + 0.037/12)¹²
A = 710(1 + 0.031)¹²
A = 710(1.031)¹²
A = 710 x 1.45
A = 1029.5
Let the annual growth rate be R. Then, we can write the function for annual growth rate after {t} years as -
1029.5 = [tex]$ 710(1 + R/1)^{t}[/tex]
1029.5 = [tex]$710(1+R)^{t}[/tex]

560Steve can paint his greenhouse in four hours working alone; his ten-year-old son can paint the greenhouse alone in nine hours. Working together, how long, to the nearest minute, would it take them
By working together, they can make the work done in two hours and forty-six minutes.
How do you calculate work done together?The equation below may be used to compute work: Work is equal to force times distance. The Newton metre is the SI unit of work (N m). When an item is moved across a distance of 1 m with 1 N of force, one joule is equal to the amount of work that is accomplished.Every time a force pushes anything over a distance, work is done. By multiplying the force by the distance travelled in the direction of the force, you may determine the amount of energy transferred, or work done.Therefore, the formula for work is W = F d s, which stands for work done equal to force times displacement.Given data :
Think of these work rates as "greenhouses per hour", not "hours per greenhouse". Then Steve's work rate is one fourth of a greenhouse per hour, and his son's is one ninth of a greenhouse per hour. Now, multiply each rate by the time t to get the portion of the greenhouse each paints, and add the products up to get one greenhouse. The work equation becomes:
1 / 4 t + 1 / 9 t = 1
9 / 36 . t + 4 / 36 t = 1
13 / 36 t = 1
36 / 13. 13 / 36 t = 36 / 13 .1
t = 36 / 13 hrs
or 36 / 13. 60 = 166 min
This is two hours and forty-six minutes.

The student is partially correct as -5 is less than -4 but ln |-5| is not less than ln |-4|.
What is reasoning?
We can ascertain the veracity of the supplied propositions using mathematical reasoning, often known as the mathematical reasoning principle.
A student said that -5 is less than -4.
This statement is correct and the reasoning is -
According to the number line, 0 is the midpoint.
From 0 to the right side of infinity the digits increases.
So, 1 is bigger than 0, 2 is bigger than 1, 3 is bigger than 2, and so on.
Similarly, from 0 to the left side of negative infinity the digits decreases.
So, -1 is smaller than 0, -2 is smaller than -1, -3 is smaller than -2, and so on.
The student also said that ln |-5| is less than ln |-4|.
This statement is false and the reasoning is -
First simplify ln |-5| and ln |-4| -
ln |-5| = ln (5)
ln (5) = 1.6094
ln |-4| = ln (4)
ln (4) = ln (2^2)
ln (2^2) = 2 ln (2)
2 ln (2) = 1.3862

2a+9b=4c
Answer:
This equation involves three variables: a, b, and c. Each variable is multiplied by a coefficient and then added together to equal a constant. To solve the equation, we must first determine what the value of the three variables are. To do this, we must use the coefficients to isolate each variable. We can start by isolating c. Divide both sides of the equation by 4 to get 2a + 9b = c. Now we can isolate b by subtracting 2a from both sides to get 9b = c - 2a. Divide both sides by 9 to get b = (c - 2a)/9. Finally, we can isolate a by subtracting 9b from both sides to get 2a = 4c - 9b. Divide both sides by 2 to get a = (4c - 9b)/2. Once we have the values of the three variables, we can substitute them into the original equation to check our work.
