Hence total cycles:-
12π/4π3cyclesAnswer is 3
The required there are 3π cycles of the function in a horizontal length of 12π.
What are functions?Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
If the period of a function is 4, that means the function completes one cycle every 4 units of horizontal distance.
To find out how many cycles occur in a horizontal length of 12π, we need to divide 12π by the period of the function, which is 4:
Number of cycles = (12π) / 4
Simplifying the expression, we get:
Number of cycles = 3π
So, there are 3π cycles of the function in a horizontal length of 12π.

x =
Answer:
39°
Step-by-step explanation:
To answer this question it's important to remember that all triangles have 3 angles which sum to 180. This means that we can set up an equation to find the missing angle
Create the equation
[tex]39+102+x=180[/tex]Combine like terms
[tex]141+x=180[/tex]Subtract 141 from both sides
[tex]x=39[/tex]This means that the missing angle is 39 degrees. Since two of the angles are equal to 39, this also means that this triangle is isosceles.

I personally think that the answer here would be C, all the birds in the forest.
The first 25 birds that were recorded are not the population.
The species with the greatest number is not the population. It is the most thriving species.
The species that are native to the area don't make up the whole population. They make up part of it, not the whole of it.
I hope this makes sense and it helps.

(30 Points) 1. State the minimum monthly income and hourly wage per worker needed to cover monthly expenses for the family you used in part a (first picture). Then, explain how to calculate the hourly wage based on the monthly income and state the hourly wage. Assume that each full-time worker works four 40-hour work weeks per month, and each part-time worker works two 40-hour weeks per month.
2. ⦁ Keeping all other criteria the same, add a child to the family you used in part a to determine the monthly expenses. How does an additional child impact the family budget and hourly wage (second picture)? Which category was least affected by this change? Explain why you think there was little impact to this category.
The minimum monthly income will be $6165 and the hourly wage to cover the expenses will be $8.5625.
How to calculate the income?From the information given, the minimum monthly income will be $6165 since that's needed to cover the expense.
Also, the hourly income will be:
= 6165/(24 × 30)
= 6165/720
= 8.5625

Steve noticed that there were 72 lights on and 78 lights turned off.
What percent of the lights are on?
Answer:
48% of the lights are on.
Step-by-step explanation:
First, gather the total amount of lights by adding the on and off lights.
72 + 78 = 150
There are 150 total lights.
Now set up a fraction to determine the percentage.
lights on/total lights = 72/150
Divide 72 by 150.
72/150 = 0.48
Multiply this by 100 to get the percent.
0.48 * 100 = 48%
48 percent of the lights are on.

Which formula can be used to show that △JKL is a right triangle?
60^2+1002=80260 squared plus 100 squared is equal to 80 squared
60^2+802=100260 squared plus 80 squared is equal to 100 squared
60^2−802=100260 squared minus 80 squared is equal to 100 squared
80^2−602=100280 squared minus 60 squared is equal to 100 squared
Answer:
2nd option
Step-by-step explanation:
using the converse of Pyhagoras' identity
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = 100 , then 100² = 10000
60² + 80² = 3600 + 6400 = 10000
then
60² + 80² = 100²
thus the triangle is right
How high will the firework be when it explodes? (Look at Photo)
Answer:
606 feet
Step-by-step explanation:
The fireword has a 5-second fuse, meaning that's how long it will take to explode.
Given the polynomial -16t² + 200t + 6, where t is the time in seconds
We need to subsitute 5 sec. (as stated in the question) for t in the polynomial, to find how high the fireworks will be when it explodes :
-16t² + 200t + 6 <== substitute 5 for t
-16(5)² + 200(5) + 6 <== square the exponent first
-16(25) + 1000 + 6 <== multiply
-400 + 1000 + 6 <== add
-400 + 1006 <== add
606 feet <== final answer
This means that it will be 606 feet high before it explodes.

The expression 40x2 – 65x 50 represents the sum of the interior angles of a regular pentagon in degrees. if the interior angles of the pentagon are equal, which expression represents the measure of two angles? 2x2(20 – 32x 25x2) 2(8x2 – 13x 10) 5x2(8x2 – 13x 10) 5(3x2 – 8x 5)
The expression which represents the measure of two interior angles of the provided regular pentagon is 16x²-26x+20.
What is regular Pentagon?Regular Pentagon is the closed shaped polygon which has 5 sides equal in measure and 5 interior angles equal in measure.
The expression, which angles represent the sum of the interior angles of a regular pentagon in degrees, is,
[tex]40x^2 - 65x +50[/tex]
The interior angles of the given pentagon are equal. A Pentagon has 5 sides. Thus, the measure of angle of interior angle of the regular pentagon is,
[tex]m\angle n=\dfrac{40x^2 - 65x +50}{5}\\m\angle n=\dfrac{5(8x^2 - 13x +10)}{5}\\m\angle n=8x^2-13x+10[/tex]
The measure of two angles is,
[tex]2m\angle n=2(8x^2-13x+10)\\2m\angle n=16x^2-26x+20[/tex]
Hence, the expression which represents the measure of two interior angles of the provided regular pentagon is 16x²-26x+20.

Two gears are in mesh. The first gear is rotating at 60 rpm and has 23 teeth. The second gear is rotating at 5 rpm. How many teeth does the second gear have
The second gear has approximately 2 teeth.
To find the number of teeth on the second gear, we can use the concept of gear ratios. The gear ratio is the ratio of the number of teeth on the first gear to the number of teeth on the second gear. It is equal to the ratio of their rotational speeds.
Gear Ratio = (Number of Teeth on First Gear) / (Number of Teeth on Second Gear)
Given that the first gear is rotating at 60 rpm and has 23 teeth, and the second gear is rotating at 5 rpm, we can set up the gear ratio equation:
60 rpm (First Gear) / 5 rpm (Second Gear) = 23 teeth (First Gear) / X teeth (Second Gear)
Now, let's solve for X (the number of teeth on the second gear):
X = (23 teeth × 5 rpm) / 60 rpm
X = 115 teeth / 60 rpm
X ≈ 1.92 teeth
Since you cannot have a fraction of a tooth, you would generally round up to the nearest whole number.
Thus, the second gear has approximately 2 teeth. However, it's important to note that it's not practical to have a gear with only 2 teeth, as it wouldn't effectively mesh with the first gear.
In real-world applications, gears typically have a higher number of teeth for smooth and efficient operation. So, in practice, the second gear would likely have a different, more practical number of teeth.
