The energy in the pendulum as it swings from point A to point B
Potential energy is converted to kinetic energy.
Now, According to the question:
Energy is defined as the ability of an object to do work. Energy can be classified in two different types of energy, Kinetic and potential energy. This two may be the principal ones, but we can see how energy manifests in different ways in nature, like heat, chemical potential energy, solar energy, electric potential energy, and so on.
Energy is constantly changing from kinetic to potential energy, and vice-versa in a pendulum. At the lowest point of the pendulum swing, the pendulum will have reach a state of maximum kinetic energy. This due to it attaining the maximum speed the pendulum can reach due to it's movement. As the pendulum start to rise again, it will start to lose kinetic energy and will gain potential energy. This loss in kinetic energy will cause the pendulum to slow down until it reaches it's max height. At this point the pendulum will have converted all of it's kinetic energy to potential energy.
Hence, Potential energy is converted to kinetic energy.

The probability of rolling a one on the first die and a four on the second die is 1/36.
This is because there are six possible outcomes for each die (1, 2, 3, 4, 5, and 6) and the probability of rolling a specific number on one die is 1/6. To find the probability of rolling a specific number on two dice, you would multiply the individual probabilities of each die (1/6 x 1/6 = 1/36). Since there is only one combination of rolling a one on the first die and a four on the second die, the probability is 1/36.

c = -1, d = -15
B) The solutions of the equation are 1+ √15 and 1- √15.
What is Quadratic equation?A quadratic equation is a type of polynomial equation that has the general form of ax² + bx + c = 0, where x is the variable, a, b, and c are constants, and a is not equal to zero.
a) To write x² - 2x - 13 in the form (x + c)² + d, we can complete the square.
First, we add and subtract (2/2)² = 1 to get:
x² - 2x - 13 = x² - 2x - 13 + 1 - 1
Next, we group the terms:
(x² - 2x) - 14 = (x² - 2x + 1) - 15
Now, we can see that the left side of the equation is a perfect square trinomial. To complete the square, we add the square of half of the coefficient of the x term, which is (1)² = 1 to both sides:
(x - 1)² - 15 = 0
So, x² - 2x - 13 = (x - 1)² - 15
c = -1, d = -15
b) Using the answer from part a, we know that x² - 2x - 13 = (x - 1)² - 15
=0
so (x-1)² = 15
x-1 = ± √15
x = 1 ± √15
The solutions of the equation are 1+ √15 and 1- √15.

Michelle bought a car that costs $25,800 and put a down of $8,000 on it. The car loan is for 60 months and has an interest rate of 3.99%. How much will she actually pay for the car? What will her monthly payment be?
Please show you’re work and be specific for both questions. Due at 10 pm!!
Answer:
$20239.6
Step-by-step explanation:
The amount financed for the car is $25,800 - $8,000 = $17,800.
To find the monthly payment, you can use the formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]
where M is the monthly payment, P is the amount financed, i is the monthly interest rate (3.99%/12), and n is the number of payments (60 months).
So,
i = 3.99%/12 = 0.00399
n = 60
M = $17,800 [ 0.00399(1 + 0.00399)^60 ] / [ (1 + 0.00399)^60 – 1]
M ≈ $337.31
So, Michelle will make monthly payments of $337.31 for 60 months.
To find the total amount that Michelle will pay for the car, you can multiply the monthly payment by the number of payments:
$337.31 x 60 = $20239.6
So, the total amount that Michelle will pay for the car is $20239.6
Solve each trigonometric function IN THE INTERVAL [0, 360).
17.) sec x + tan x = 1
The solution of the trigonometric function in the interval is x = 0
What is a trigonometric function?A trigonometric function is an equation that contains the trigonometric ratios.
How to solve the given trigonometric function?Given the trigonometric function secx + tanx = 1, we proceed to solve it as follows.
secx + tanx = 1
Using the trigonometric identity tan²x + 1 = sec²x
⇒ secx = √(1 + tan²x)
So, substituting this into the equation, we have that
secx + tanx = 1
√(1 + tan²x) + tanx = 1
√(1 + tan²x) = 1 - tanx
Squaring both sides of the equation, we have that
√(1 + tan²x) = 1 - tanx
√(1 + tan²x)² = (1 - tanx)²
1 + tan²x = 1 - 2tanx + tan²x
Substracting 1 from both sides, we have that
1 - 1 + tan²x = 1 - 1 - 2tanx + tan²x
0 + tan²x = 0 - 2tanx + tan²x
tan²x = - 2tanx + tan²x
Substracting tan²x from both sides, we have that
tan²x - tan²x= - 2tanx + tan²x - tan²x
0 = -2tanx + 0
0 = -2tanx
tanx = 0/-2
tanx = 0
taking inverse tan, we have that
x = tan⁻¹0
x = 0
So, the solution is x = 0

Steve needs to earn a C in his Sociology class. His current test scores are 70, 77, 71, and 71. His final exam is worth 3 test scores. In order to earn a C, Steve's average must lie between 70 and 79 inclusive. What range of scores can Steve receive on the final exam to earn a C in the course
The range of scores that Steve needs to get an average of 70 to 79 is 66 to 87 Points.
To find the range of scores that Steve needs to have to stay in the 70 to 79 range we first need to define the variables that we need to find.
Let x = Score that Steve needs
Since the exam is worth 3 exams, we will then use 3x to denote the weight of the final exam.
Now we need to add all the other exams and divide it by the number of exams.
[tex]\frac{3x + 70+77+71+71}{7} = 70[/tex]
3x + 292 = 7 *70
3x = 490 -292
3x = 198
[tex]\frac{3x}{3} =\frac{198}{3}[/tex]
x = 66
Now let's look for the score that Steve needs to get to a 79 average.
[tex]\frac{3x + 70+77+71+71}{7} = 79[/tex]
3x + 292 = 7 * 79
3x + 292 = 553
3x = 553 - 292
3x = 261
x = 87

A container has a capacity of 20 litres. It is filled with wine whose density is 0.8kg/litre. What is the mass of the wine?
The mass of the wine can be found by multiplying the density of the wine (0.8 kg/litre) by the volume of the wine (20 litres). The mass of the wine is 16 kg.
What makes for an excellent density example?Its density is how much "stuff" can fit into a certain quantity of space. For instance, a block of the more resilient, lighter element gold (Au) will have a higher density than a block of the more substantial element lead (Pb) (Au). Styrofoam blocks are not as dense as bricks. Mass per unit volume serves as its definition.
We use the word "density" to indicate how much space (or "volume") an object or substance occupies in relation to the amount of matter contained therein (its mass). Density can also be defined as the quantity of mass per unit of volume.
mass = density x volume
mass = 0.8 kg/litre x 20 litres
mass = 16 kg
So, the mass of the wine is 16 kg.

Note that the rule that describes the transformation shown is: (x,y) → (x+7,-y)(Number 2)
A transformation is a broad phrase covering four distinct methods of changing the shape and/or location of a point, line, or geometric figure. The Pre-Image is the original shape of the item, and the Image is the final shape and location of the object after the transformation.
Thus, with regard to the transformation above,
At Point A: The original coordinate of point A was (-6,-6).
The coordinate after the transformation is A'(1,6), which eliminates option 3.
At Point B:
The original coordinate of point B was (-2,4).
After the transformation, we have B'(5,-4), which eliminates option 1 and option 4. It is therefore right to state that (x,y) → (x+7,-y) is the correct representation of the transformation.

===============================================
Explanation:
We'll use the pythagorean theorem converse.
Consider a triangle with sides a,b,c where c is the longest side.
There are 3 scenarios possible:
If a^2+b^2 > c^2, then the triangle is acute.If a^2+b^2 = c^2, then it is a right triangle.If a^2+b^2 < c^2, then the triangle is obtuse.The middle or second scenario is probably what you're most familiar with. That's the famous pythagorean theorem without the term "converse" attached to it.
--------------
The two given sides are 8 inches and 10 inches.
Let's say the third side was 5 inches (choice F)
This means we have a triangle with sides a = 5, b = 8, c = 10
Then compute the following:
a^2+b^2 = (5)^2 + (8)^2 = 89c^2 = (10)^2 = 100Since 89 < 100, we see that a^2+b^2 < c^2 is the case. Therefore the triangle with sides 5,8,10 is obtuse.
This will allow us to rule out choice F since we're looking for an acute triangle.
--------------
Now onto choice G.
This time the sides are: a = 6, b = 8, c = 10
a^2+b^2 = (6)^2 + (8)^2 = 100c^2 = (10)^2 = 100Both results (a^2+b^2 and c^2) are the same at 100; so we see that a^2+b^2 = c^2.
Therefore we have a right triangle. We can rule out choice G.
--------------
Now onto choice H.
The triangle now has sides: a = 8, b = 10, c = 12
a^2+b^2 = (8)^2 + (10)^2 = 164c^2 = (12)^2 = 144Since 164 > 144, we see that a^2+b^2 > c^2 is the case. Therefore the triangle with side lengths 8,10,12 is acute.
Choice H is the final answer.--------------
For the sake of completeness, let's go over choice J.
a = 8, b = 10, c = 13a^2+b^2 = (8)^2 + (10)^2 = 164c^2 = (13)^2 = 169We find 164 < 169 which leads to the scenario a^2+b^2 < c^2. The triangle for choice J is obtuse. We can rule out choice J.
You can use something like GeoGebra to help visually verify these results.

suppose you have ten dies with six faces each. if you randomly throw these dies, what the probability that the sum of all the top faces is divisible by 6?
The probability that the sum of all the top faces is divisible by 6 is 1/6.
1.This is because there are six possible outcomes when the dice are thrown, and only one of these outcomes (where the sum of the top faces is divisible by 6) has a probability of 1/6.
2.The other five outcomes have a probability of 0.
3.To explain this further, consider the following example: if we throw 10 dice, the possible outcomes are 6^10, or 6,561 outcomes. Of these 6,561 outcomes, only 1,089 will result in a sum of the top faces that is divisible by 6.
4.Therefore, the probability that the sum of all the top faces is divisible by 6 is 1,089/6,561, or 1/6.

Tomika and Mark claim a medical deduction in the amount of $1,839.8.
What is the percentage?
A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage, therefore, refers to a part per hundred. Per 100 is what the word percent means. It is represented by the symbol “%
Given that the gross income is $101,598
Medical insurance = 7.5 % of $101,598
= 7.5% x $101,598
= $7,619.88.
The insurance covered 60% of the medical expenses.
Medical deduction claim = $7,619.88 - (100% - 60%)x $3,800
