which of the following equations describe the graph shown below?
find the derivative of the given function at the indicated point f(x)=1/x a=2
Final answer:
The derivative of the function f(x) = 1/x at x = 2 is -1/4, found using the power rule of differentiation.
Explanation:
To find the derivative of the function f(x) = 1/x at the point where a = 2, we employ the power rule of differentiation. The function can be rewritten as f(x) = x-1. Applying the power rule (f'(x) = n*xn-1) to this function, the derivative is f'(x) = -1*x-2 or f'(x) = -1/x2. To find the derivative at x = 2, we simply substitute x with 2, giving us f'(2) = -1/22 = -1/4.

FM = 5y + 13, MG = 5 - 3y, FG = ? M is the midpoint of FG. Use the given information to find the missing measure or value.
A line is a one-dimensional shape that is straight. The length of the side FG is 16 units.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
Given that FM = 5y + 13 and MG = 5 - 3y. Also, midpoint of the line FG is M, therefore, the length of the two segments FM and MG will be equal to each other.
FM = MG
5y + 13 = 5 - 3y
5y + 3y = 5 - 13
8y = -8
y = -8/8
y = -1
Now, the length of the two line segments will be,
FG = FM + MG
= 2y + 13 + 5
= 2y + 18
= 2(-1) + 18
= -2 + 18
= 16
Hence, the length of the side FG is 16 units.

Answer:

Step-by-step explanation:
good question
The factor that needs to be multiplied by the (p/g, i, n) factor to obtain the (f/g, i, n) factor is the conversion factor between the two units of measurement being used for the factor.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
In this case, the units of measurement for both factors are not specified, so it's not possible to determine the specific conversion factor needed. However, in general, if the two factors are expressing the same quantity but in different units (for example, feet and meters), then the conversion factor between those two units would be used to convert the (p/g, i, n) factor to the appropriate units before multiplying it by the (f/g, i, n) factor.
Thus,
The factor that needs to be multiplied by the (p/g, i, n) factor to obtain the (f/g, i, n) factor is the conversion factor between the two units of measurement being used for the factor.

Find the equation of the line passing through (4,3) and parallel to the line whose equation is y=2x-6
Which of the following is true for the relation f(x) = 2x2 + 1?
Only the equation is a function.
Neither the equation nor its inverse is a function.
Both the equation and its inverse are functions.
Only the inverse is a function.
Answer:
Both the equation and its inverse are functions.
Step-by-step explanation:
Since, a relation is called a function when an input value of the relation has only one output value,
Here, the given relation,
[tex]f(x) = 2x^2 + 1[/tex]
When we plot the graph of this function,
We observed that all vertical line intersects the graph exactly once, except
, x = 0,
Thus, by vertical line test,
In the given equation every x has only one output value,
⇒ f(x) is a function,
Now, the inverse of a function is also a function,
⇒ [tex]f^{-1}(x)[/tex] is also a function,
Hence, Both the equation and its inverse are functions.

How to simplify equations with fractional exponents?
Final answer:
To simplify equations with fractional exponents, divide the digit term of the numerator by the digit term of the denominator and subtract the exponents of the exponential terms. Then multiply the numerators and denominators together and simplify by common factors if needed.
Explanation:
When simplifying equations with fractional exponents, we can follow these steps:
Divide the digit term of the numerator by the digit term of the denominator.Subtract the exponents of the exponential terms.Multiply the numerators and denominators together and simplify by common factors if needed.For example, let's simplify the equation √(x³ / y²). We divide x³ by y², which gives us x/y. Then we subtract the exponents, resulting in √(x/y). Finally, we can simplify the fractional exponent by taking the square root of x/y, which gives us √(x/y).

A person can burn about 9 calories per minute bicycling. Let x represent the number of minutes bicycled, and let y represent the number of calories burned. Create a mapping diagram to show the number of calories burned by bicycling for 50, 100, 150, or 200 minutes. Determine the domain and range of the relation in context and explain whether or not this represents a function.
Final answer:
A mapping diagram to show the number of calories burned by bicycling for different durations has been created. The domain is {50, 100, 150, 200} minutes, and the range is {450, 900, 1350, 1800} calories. This represents a function because each time duration maps to exactly one calorie value.
Explanation:
To create a mapping diagram that represents the number of calories burned by bicycling for 50, 100, 150, or 200 minutes, we consider that a person burns about 9 calories per minute. Let x represent the number of minutes bicycled, and let y represent the number of calories burned. The mapping diagram looks like this:
50 minutes → 50 × 9 = 450 calories
100 minutes → 100 × 9 = 900 calories
150 minutes → 150 × 9 = 1350 calories
200 minutes → 200 × 9 = 1800 calories
The domain of this relation is the set of minutes bicycled, which is {50, 100, 150, 200}, and the range is the set of calories burned, which is {450, 900, 1350, 1800}. This does represent a function because for each value in the domain, there is exactly one corresponding value in the range.
