A sector has a radius of 12 centimeters and an angle 65 degrees. find its arc length
Answers
If the radius of sector is 12 centimeters and angle of 65 degrees then the arc's length is 13.6 cm.
Given a sector has a radius of 12 cm and an angle 65 degrees.
We have to calculate arc's length.
We know that arc's length is equal to Θr where Θ is in radians.
We have been given angle in degrees ,so we have to convert degrees in radians.
Angle=65*π/180=13π/36
length of arc =Θr
Putting the values in the formula above :
length =13π/36*12
=13*3.14/3
=40.82/3
=13.6
Hence if the radius of sphere is 12 cm and angle 65 degrees then the length of arc of sphere is 13.6 cm.

Find the hypothesis for side a 16 side b 20
Answers
I think you mean to say "hypotenuse". If so, then use the pythagorean theorem to get the following
a^2 + b^2 = c^2
16^2 + 20^2 = c^2

656 = c^2
c^2 = 656
c = sqrt(656)
c = sqrt(16*41)
c = sqrt(16)*sqrt(41)
c = 4*sqrt(41)

How much money will Savannah have after 10 days? How many days will it take for her to have at least $1.50? Justify your answer with a mathematical model of the problem situation.
Answers
Answer:
Savannah will have 35 pennies after 10 days.
It will take her 49 days to have at least $1.50
Step-by-step explanation:
Start Value = .05
Linear Increase = .03
.05 + .03x = TV
TV = Total Value
10 days = .05 + .03(10)
10 days = $.35
.05 + .03x = 1.50
1.50 - .05 = 1.45
1.45/.03 = 48.33
48 days is not enough for her to have 1.50 as she is not gaining hourly but rather daily so it would take her 49 days to have at least 49

Calculate the horse's average speed for the race in units of kilometers per hour ().
*Round your answer to the correct number of significant figures.
Answers
The horse's average speed for the race in units of kilometers per hour will be 178.06.
The winning horse in a recent race covered the 5.50-furlong distance in 22.37 seconds.
The distance covered by the particle or the body in an hour is called the average speed. It is a scalar quantity. It is the ratio of the total distance to the total time.
We know that the average speed formula is given as,
Average speed = Total distance / Total time
The conversion is given as,
1 furlong = 0.201168 km
5.50-furlong = 0.201168 x 5.5 km
5.50-furlong = 1.10642 km
1 second = 1/3600 hour
22.37 seconds = 22.37/3600 hour
22.37 seconds = 0.0062 hour
The average speed is calculated as,
Average speed = 1.10642 / 0.0062
Average speed = 178.06 km per hour
The horse's average speed for the race in units of kilometers per hour will be 178.06.

Begin by graphing the absolute value function, . Then use transformations of this graph to graph the given function. h(x)= /x/ - 4
Answers
The value of the modulus function is g ( x ) = | x | - 4
What is Modulus Function?Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the absolute value function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = | x | be equation (1)
Now , the function f ( x ) is shifted vertically down by 4 units
Down by d units: y = f(x) - d
Substituting the values in the equation , we get
Let the translated function be represented as g ( x )
g ( x ) = f ( x ) - 4
On simplifying the equation , we get
g ( x ) = | x | - 4

Determine the interest on the following notes: (Use 360 days for calculation.) (a) $5,600 at 5% for 90 days. $ (b) $1,280 at 9% for 5 months. $ (c) $6,900 at 8% for 60 days. $ (d) $2,000 at 7% for 6 months. $
Answers
Therefore, the interest on the notes would be:(a) $70 (b) $45 (c) $92 (d) $70.
To determine the interest on the given notes, we can use the simple interest formula:
Interest = Principal * Rate * Time
(a) For $5,600 at 5% for 90 days:
Principal = $5,600, Rate = 5% (or 0.05), Time = 90 days/360 (converted to years)
Interest = $5,600 * 0.05 * (90/360) = $70
(b) For $1,280 at 9% for 5 months:
Principal = $1,280, Rate = 9% (or 0.09), Time = 5 months/12 (converted to years)
Interest = $1,280 * 0.09 * (5/12) = $45
(c) For $6,900 at 8% for 60 days:
Principal = $6,900, Rate = 8% (or 0.08), Time = 60 days/360 (converted to years)
Interest = $6,900 * 0.08 * (60/360) = $92
(d) For $2,000 at 7% for 6 months:
Principal = $2,000, Rate = 7% (or 0.07), Time = 6 months/12 (converted to years)
Interest = $2,000 * 0.07 * (6/12) = $70

Answers
OLAP is used for the analysis of accumulated data, and it requires a data warehouse.
while OLTP is used for transaction processing and requires a database optimized for real-time transaction processing. The analysis of accumulated data is known as Online Analytical Processing (OLAP), and it involves a data warehouse. OLAP is a business intelligence tool used for multi-dimensional analysis of large data sets, while a data warehouse is a central repository that stores historical and current data from multiple sources in a structured manner. OLAP allows users to perform complex queries on large data sets, analyze trends, and make informed business decisions. It is often used in data mining and decision support systems. OLAP tools can be used to slice and dice data, drill down to more detailed data, and roll up to higher levels of summary data. OLAP is primarily used for analytical purposes and is not designed for transaction processing. On the other hand, a data warehouse is designed to support OLAP and is used for storing large amounts of historical data that can be queried and analyzed. Data is extracted from various sources, transformed, and loaded into the data warehouse in a structured format, enabling efficient querying and analysis. OLTP (Online Transaction Processing), on the other hand, is a type of transaction processing that is designed for processing real-time transactions in databases. It is used for day-to-day operations such as order processing, inventory management, and customer management. OLTP is optimized for processing large volumes of transactions in real-time, and is not suitable for analytical purposes.
In summary, OLAP is used for the analysis of accumulated data, and it requires a data warehouse, while OLTP is used for transaction processing and requires a database optimized for real-time transaction processing.

The derivative of the function \(G(y) = In (4y + 1)^2 \sqrt JA 4 + 1\) is \(g'(y) = 8y^7 / (y+2)^5 - 16y^6 / (y+2)^4.\)
To find the derivative of the function \(g(y) = (y^2 / (y+2))^4\), we can use the chain rule and the power rule of derivatives.
First, using the quotient rule, we can simplify the function as follows:
\(G(y) = In (4y + 1)^2 \sqrt JA 4 + 1\)
Now, applying the chain rule and the power rule:
\(G' (y) = (1-2y^3)/((4y+1)(y^4+1)) \\g'(y) = 8y^7 / (y+2)^5 - 16y^6 / (y+2)^4\)
Therefore, the derivative of the function is:

if you assume all outcomes are equally likely, what is the probability of getting either two odd numbers or two even numbers?
Answers
The probability of getting two odd numbers or two even numbers is 50%, since there are an equal number of odd and even numbers.
There are 6 possible outcomes when rolling two dice:
(1,1), (1,2), (2,1), (2,2), (1,3), (3,1).
The probability of getting two odd numbers is
2/6, or 1/3.
The probability of getting two even numbers is also
2/6, or 1/3.
Therefore, the probability of getting either two odd numbers or two even numbers is 2/3.
The probability of getting two odd numbers or two even numbers is 50%. This is because there are an equal number of odd and even numbers, so each outcome is equally likely. This means that the probability of getting two odd numbers or two even numbers is the same as the probability of getting one odd number and one even number. In both cases, the probability is 50%, since each outcome is equally likely. Therefore, the probability of getting two odd numbers or two even numbers is 50% as there are an equal number of odd and even numbers. This is because all possible outcomes are equally likely, and there are an equal number of odd and even numbers, so the probability of getting either two odd numbers or two even numbers is the same.
