Answer:
1/4
Step-by-step explanation:
You cannot subtract (or add) a fraction with different denominators so first, you need to find a common denominator. You can do this by finding the least common multiple (LCM).
Here the denominators are 2 and 4 so the LCM is 4.
After you find the LCM you need to multiply the denominator by a number that equals the LCM. Then multiply the numerator by that same number.
So convert both 1/2 and 1/4
1/4 x 1/1 = 1/4
1/2 x 2/2 = 2/4
Now we can just subtract the numerator from each other.
2/4 - 1/4 = 1/4
We cannot simplify the difference any more so keep it the same.

What is 200 Micrograms (mcg) in Milligrams (mg)?
To convert 200 micrograms (mcg) to milligrams (mg), we need to use the conversion factor that 1 milligram is equal to 1000 micrograms, 200 micrograms (mcg) is equal to 0.2 milligrams (mg).
When we want to convert a unit of measurement to another unit of measurement, we use conversion factors to make the conversion. In the case of converting micrograms (mcg) to milligrams (mg), we need to know that 1 milligram is equal to 1000 micrograms. This means that to convert any value from micrograms to milligrams, we need to divide by 1000.
To convert 200 micrograms (mcg) to milligrams (mg), we need to use the conversion factor that 1 milligram is equal to 1000 micrograms.
So, to convert 200 mcg to mg, we divide 200 by 1000:
200 mcg ÷ 1000 = 0.2 mg
Therefore, 200 micrograms (mcg) is equal to 0.2 milligrams (mg)
It is important to understand the concept of unit conversions because it is a crucial aspect of many scientific and engineering calculations. Knowing how to convert units of measurement allows us to work with data that is expressed in different units and compare results from different experiments.

How do you find the two largest numbers in an array in Matlab?
To find the two largest numbers in an array in Matlab, you can use the sort function and indexing to access the two largest elements.
Here's an example:
array = [3, 8, 2, 10, 5];
sorted_array = sort(array, 'descend');
largest_number = sorted_array(1);
second_largest_number = sorted_array(2);
In this example, we have an array of numbers called array. We use the sort function to sort the array in descending order, which means that the largest numbers will be at the beginning of the array. The resulting sorted array is assigned to a new variable called sorted_array.
We then use indexing to access the first and second elements of the sorted array, which will be the two largest numbers. These numbers are assigned to the variables largest_number and second_largest_number, respectively.
It's important to note that if the array contains duplicate values, this method will return the two largest unique values. If you want to find the two largest values including duplicates, you can use the max function twice with the 'omitnan' parameter to handle any NaN values in the array:
array = [3, 8, 2, 10, 5, 10];
largest_number = max(array, [], 'omitnan');
array_without_largest_number = array(array < largest_number);
second_largest_number = max(array_without_largest_number, [], 'omitnan');
In this example, we first find the largest number in the array using the max function with the 'omitnan' parameter to ignore any NaN values. We then create a new array that excludes the largest number, and use the max function again to find the second largest number in the new array.

Step-by-step explanation:took the test and i got it right
An isosceles trapezoid with a short base of 3 meters and a height of 5 meters then the area of the trapezoid is 35 m²
What is the area of the trapezoid?
To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
We can start by finding the length of the long base. Since the trapezoid is isosceles, we know that the length of the portion of the large base from the left vertex to the perpendicular is equal to the length of the portion from the right vertex to the perpendicular. Let's call the length of the long base "x":
x = 4 + 7 = 11 meters
Now we can use the formula for the area of a trapezoid:
Area = (1/2) * (short base + long base) * height
Substituting the values we have:
Area = (1/2) * (3 + 11) * 5
Area = 7 * 5
Area = 35 m²
Therefore, the area of the trapezoid is 35 m².

O f(1) = √21+2+3
The inverse of function is f(x) = (x - 4)³/8 + 3
What is inverse function?A function that reverses the results of another function is known as an inverse function. If y = f(x), then x = g(y), then a function g is the opposite of a function f. To put it another way, applying f and then g is equivalent to doing nothing. This can be expressed as g(f(x)) = x in terms of how f and g are made up.
Given g(x) = 2(∛x-3)+4
let g(x) = y
y = 2(∛x-3)+4
change the variables since options are in form of x
x = 2(∛y-3)+4
simplify for y
subtract 4 from both side
x - 4 = 2(∛y-3)+4 - 4
x - 4 = 2(∛y-3)
divide both side by 2
(x - 4)/2 = (2(∛y-3))/2
(x - 4)/2 = (∛y-3)
cube both side
((x - 4)/2)³ = ((∛y-3))³

what is convergence radius calculator
A convergence radius calculator is a tool used in calculus to calculate the radius of convergence for a power series using the ratio test.
To calculate the convergence radius of a power series, one can use a formula known as the "ratio test". The ratio test involves taking the limit of the absolute value of the ratio of successive terms in the series, as n approaches infinity. If this limit exists and is less than 1, then the series converges absolutely. The convergence radius can then be found as the reciprocal of this limit.
For example, given the power series:
∑(n=0 to infinity) [tex](x-2)^n / n^2[/tex]
we can use the ratio test to find the convergence radius as follows:
[tex]|(x-2)^(n+1) / (n+1)^2| / |(x-2)^n / n^2|[/tex]
= [tex]|(x-2) / (n+1)|^2 * (n^2 / (x-2)^2)[/tex]
= [tex](n^2 / (n+1)^2) * (1 / (x-2)^2)[/tex]
= [tex]n^2 / ((n+1)^2 * (x-2)^2)[/tex]
Taking the limit of this expression as n approaches infinity, we get:
[tex]lim(n- > ∞) (n^2 / ((n+1)^2 * (x-2)^2))[/tex]
= [tex]1 / (x-2)^2[/tex]
Since this limit exists and is less than 1 for all x except x=2, the power series converges absolutely for all values of x within a radius of [tex]1/(x-2)^2[/tex] centered at x=2. Therefore, the convergence radius of the power series is 1.

The magnitude of given operations of vectors are found.
What are Vectors?Quantities with the independent characteristics of magnitude and direction are called vectors.
Given:
u = (-3, 8) and v = (-14, 6)
So, 3u = (-9, 24) and 2v = (-28, 12)
3u - 2v = (-9+28, 24-12)
3u - 2v = (19, 12)
Magnitude of 3u - 2v = √19² + 12² = √505 units
2u = (-6, 16) and 3v = (-42, 18)
2u - 3v = (36, -2)
Magnitude = √36² + (-2)² = √1300 units
u = (-3, 8) and 4v = (-56, 24)
u + 4v = (-59, 32)
Magnitude = √(-59)² + 32² = √4505 units

If f(1) = 0, what are all the roots of the function ? use the remainder theorem.
By using synthetic division, we can find all the roots of the function f(x) = x³ + 3x² - x - 3 and determine that the roots are 1, -1, and -3.
A root of a function is a value for x that makes the function equal to zero.
In this case, we have a function f(x) = x³ + 3x² - x - 3 and we know that f(1) = 0. To find all the roots of this function, we can use the remainder theorem.
The remainder theorem states that if we divide a polynomial by a linear expression (such as x - a), the remainder will be equal to the value of the polynomial at that value of x (a). In other words, if we write f(x) = (x - a)q(x) + r, where r is the remainder, then f(a) = r.
So, if we divide our function f(x) by x - 1, the remainder will be equal to f(1), which we know is zero. Therefore, (x - 1) is a factor of f(x), and the function has a root at x = 1.
Next, we can divide f(x) by (x - 1) to get a quotient, q(x), and a new remainder, r. We can repeat this process, dividing q(x) by another linear expression until we have no more remainders.
The roots of f(x) will be the values of x that we used as factors in each step of the division process.
This process of dividing a polynomial by a linear expression to find its roots is called synthetic division.
