The modification that would have to result in a net worth of $100,000 is: adding $1,000 in credit card debt. Option D
How to solve for the net worthThey currently have $101,000 in assets.
We have the value of the automobile plus the value of the recreational vehicle.
110000+27000 = 137000
When the medical expenses are subtracted from the net assets, we have
137000-8700 = 128300
When the loan sum is subtracted from net value, we have
128300-80000 = 48300
Savings and net wealth together provide us
48300+5000 = 53300
Retirement money added to net worth gives us
53000+50000 = 103300
After deducting the credit card debt from net value, we have
103300-2300 = 101000
We deduct $1,000 from this to create $100,000. Therefore, choice D is the best one.

Richard and Teo have a combined age of 36. Richard is 15 years older than twice Teo's age. How old are Richard and Teo?
Teo is 10.5 years old and Richard is 25.5 years old.
How old are Richard and Teo?Represent Teo's age with x.
Using the above as a guide, we have the following:
Richard = x + 15
Their combined age is 36
So, we have the following representation
x + (x + 15) = 36
Evaluate the like terms
2x + 15 = 36
2x = 21
x = 10.5
Recall that
Richard = x + 15
So, we have
Richard = 10.5 + 15
Richard = 25.5

How to use rigid transformations on functions
In this problem we find four cases of functions that must be transformed by rigid transformations. Rigid transformations are transformations applied on functions such that its features are not altered. We should apply, if possible, the following rigid transformations:
Reflection across the y-axis
f(x) → f(- x)
Translation to the right
f(x) → f(x - k), where k > 0
Translation downward
f(x) → f(x) - k, where k > 0
Now we proceed to determine the image of each function:
Case 1
f(x) = √x
Reflection across the y-axis
f(x) = √(- x)
Case 2
Translation 4 units right
f(x) = √(x - 4)
Case 3
Translation 3 units down
f(x) = √x - 3
Case 4
Translation 4 units right and 4 units down
f(x) = √(x - 4) - 4

Let f(x) = √x-5 for x ≥ 5
Find f^-1(2)
Answer: To find the inverse of the function f(x), we need to switch the roles of x and y, so that x becomes the dependent variable and y becomes the independent variable. Then, we need to solve for x in terms of y.
Let y = √x - 5, then x = y^2 + 5.
To find f^-1(2), we need to substitute 2 for y in the equation x = y^2 + 5:
x = 2^2 + 5 = 9
So f^-1(2) = 9.
This means that the inverse of f(x) at 2 is 9. In other words, if f(x) = 2, then x = 9.

write an exponential function that has a y-intercept of -4 and passes through the points (1, -1.6) and (2, -0.64)
The function can be used to model the exponential growth or decay that occurs in real-life situations that fit this particular pattern is y = 4(-0.4)ˣ + -4
An exponential function is a mathematical function that has the form
=> y = abˣ,
where a is a constant and b is the base of the exponential.
To start, we will use the first point, (1, -1.6), to write an equation that relates x and y. Let's call the constant a in our exponential function "k". Using the point (1, -1.6), we can write the equation:
=> -1.6 = k * b¹
Next, we will use the second point, (2, -0.64), to write another equation that relates x and y. Using the point (2, -0.64), we can write the equation:
=> -0.64 = k * b²
Now that we have two equations, we can solve for the two unknowns, k and b, by dividing the two equations:
=> (-0.64) / (-1.6) = k * b² / k * b¹
b = (0.64 / -1.6)¹
b = -0.4
With b determined, we can substitute it back into one of the equations and solve for k:
=> -1.6 = k * (-0.4)¹
=> k = -1.6 / (-0.4)
=> k = 4
So our exponential function that passes through the points (1, -1.6) and (2, -0.64) and has a y-intercept of -4 is:
y = 4 * (-0.4)ˣ + -4

Dina has a circular table. she wants to paint around the edge of the table. If the table has a radius of 3.5 feet, how long is the part of the table she will be painting?
The length of the part of the table that Dina will be painting is 21.991595 feet.
What do you mean by Circumference?Circumference refers to the distance around the edge of a circle. It is the length of the perimeter of a circle and is defined as the product of the circle's radius and its constant pi (π). The formula for the circumference of a circle is:
C = 2πr
where C is the circumference, π is approximately equal to 3.14, and r is the radius of the circle.
The circumference of a circle is an important concept in geometry, trigonometry, and engineering, as it provides a measure of the size and shape of a circular object. Circumference is used in many applications, such as determining the size of wheels, gears, and other circular objects, as well as in the calculation of areas and volumes of circular shapes.
To find the length of the part of the circular table that Dina will be painting, we need to find the circumference of the circle.
Circumference = 2 * π * r
Where r is the radius of the circle. In this case, the radius is 3.5 feet, so:
Circumference = 2 * π * 3.5
Circumference = 2 * 3.14159 * 3.5
Circumference = 21.991595 feet (to 4 decimal places)
So, the length of the part of the table that Dina will be painting is 21.991595 feet.

What is Intersection points?
The point at which two lines or curves intersect is referred to as the point of intersection. The point at which two curves intersect is crucial because it is the point at which the two curves take on the same value.
The given curves are the polar equations of two circles with radii 6. To find their intersection points, we can set the two equations equal to each other and solve for Ф.
6 sin(Ф) = 6 cos(Ф)
Dividing both sides by 6 and rearranging terms, we get:
tan(Ф) = 1
This equation has infinitely many solutions, but we are only interested in those that lie in the interval [0, π/2].
Ф = π/4 satisfies this condition and corresponds to the point (6, 6) in Cartesian coordinates.
Since the two curves are circles, they are symmetrical about the origin. Therefore, we can deduce that the other intersection point is (-6, -6).
