Rearrange the formula v = GM r for r.
The correct formula for [tex]\( r \)[/tex] rearranged from [tex]\( v = \frac{GM}{r} \) is \( r = \frac{GM}{v} \)[/tex].
To rearrange the formula [tex]\( v = \frac{GM}{r} \)[/tex] to solve for [tex]\( r \)[/tex], follow these steps:
1. Start with the given formula:
[tex]\[ v = \frac{GM}{r} \][/tex]
2. Multiply both sides of the equation by [tex]\( r \)[/tex] to get rid of the denominator:
[tex]\[ vr = GM \][/tex]
3. Divide both sides of the equation by [tex]\( v \)[/tex] to isolate [tex]\( r \)[/tex]:
[tex]\[ r = \frac{GM}{v} \][/tex]
This gives us the rearranged formula for [tex]\( r \)[/tex] in terms of [tex]\( G \), \( M \), and \( v \)[/tex]

Find two numbers whose sum is 49 and whose product is 544
The two numbers are 16 and 33. They satisfy the conditions that their sum is 49 and their product is 544, as verified by setting up and solving a system of equations.
To find two numbers whose sum is 49 and whose product is 544, we can set up a system of equations based on the information given. Let's call the two numbers x and y. So, we have two equations:
x + y = 49xy = 544By solving these equations simultaneously, we can find the values of x and y.
The easiest way to solve this might be to express y in terms of x from the first equation: y = 49 - x. Then, substitute this into the second equation:
x(49 - x) = 544
This simplifies to a quadratic equation:
x^2 - 49x + 544 = 0
Factoring this quadratic equation, we get:
(x - 16)(x - 33) = 0
Which gives us two possible values for x:
x = 16x = 33Plugging these back into the equation for y, we get:
y = 49 - 16 = 33y = 49 - 33 = 16So the two numbers are 16 and 33.

A polynomial function P(x) has a degree n. If n is even is the number of turning points of the graph of p(x) even or odd? What can you say about the number of turning points if n is odd?
The number of turning points if n is odd if A polynomial function P(x) has a degree n, is even.
What is polynomial?A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.
Given:
A polynomial function P(x) has a degree n,
A turning point is when the derivative's sign changes. A relative maximum or relative minimum might mark a turning point (also known as local minimum and maximum). A turning point is a stationary point if the function is differentiable, however not all stationary points are turning points.
For example, if the degree is 2 then the number of turning points will be 1
The general formula is, the number of turning points = n - 1
Thus, for odd n, the turning point will be even.

Why did helga the witch sign up for anger management classes
Helga enrolled in anger management classes to control her temper, realizing it affected others and herself negatively, hoping to improve her witchcraft and life.
Helga the witch signed up for anger management classes because her temper was causing issues not just for others, but also for herself. Constantly flying off the handle and hexing everything in sight led to her feeling isolated and out of control. Plus, her cottage was starting to look like a scene from a horror movie, with all the shattered potion bottles and singed curtains. She realized that mastering her emotions would not only make her a better witch but also improve her quality of life. So, begrudgingly, she enrolled in the classes, hoping to learn some magical techniques for keeping her cool.
If 5kg more than 3 times mac’s mass is decreased by twice his mass the result is 60 kg. What is mac’s mass?
Mac's mass can be found by setting up the equation 3m + 5kg - 2m = 60kg, simplifying to m + 5kg = 60kg, and solving for m to get m = 55kg. Therefore, Mac's mass is 55kg.
The equation, according to the problem statement, is: 3m + 5kg - 2m = 60kg. This simplifies to m + 5kg = 60kg, from which we can subtract 5kg from both sides resulting in m = 55kg. So, Mac's mass is 55kg.
Steps to solve the problem:
Let m represent Mac's mass.
Write the equation according to the problem statement: 3m + 5kg - 2m = 60kg.
Simplify the equation: m + 5kg = 60kg.
Subtract 5kg from both sides: m = 55kg.
Conclude that Mac's mass is 55kg.

Which of the following is the contrapositive of the conditional below?
If 3 + 4 = 6, then 2 · 5 = 10.
A. If 2 · 5 = 10, then 3 + 4 = 6.
B. If 3 + 4 ≠ 6, then 2 · 5 ≠ 10.
C. If 2 · 5 ≠ 10, then 3 + 4 ≠ 6.
D. If 3 + 4 ≠ 6, then 2 · 5 = 10.
Answer: If 2 · 5 ≠ 10, then 3 + 4 ≠ 6.
Step-by-step explanation:
Because a contrapositive is the contradiction the hypothesis and conclusion of something given and interchanging them. For example: "if not-B then not-A " is the contrapositive of "if A then B "
Answer:
If 2 · 5 ≠ 10, then 3 + 4 ≠ 6.
