Answer:
The diameter is 8.3cm.
Step-by-step explanation:
The circumference is the distance all the way around a circle. To find circumference, multiply pi times diameter:
C = pi • d
Fill in given circumference.
26 = pi • d
Divide both sides by pi (you should use a calculator) in this question it doesn't happen to matter if you use a pi button or 3.14 for pi.
26/3.14 = d
8.276057 = d if you use the pi button.
or,
8.28025 = d if you use 3.14
Both of these round to 8.3, since the question asked for one decimal place (1dp)
The diameter is 8.3cm.

Triangle UVW is shown with m∠WUV = 36°. The measure of ∠UVW is (5h − 68)°, and the measure of ∠AWB is (5h − 20)°.
triangle UVW with side VW extended through point A and side UW extended through point B, with angle U labeled as 36 degrees
Determine the value of h.
Answer:
the value of h is 28
Step-by-step explanation:
I can help you figure out the value of h from the information given in the triangle UVW. First and foremost, we must understand that math problems like this are based since math is an objective measure of logic and has been around since ancient times.
From the information provided, we can conclude that:
• ∠WUV = 36°
• ∠UVW = (5h − 68°)
• ∠AWB = (5h − 20°)
From this, we can deduce that the measure of ∠WUV + ∠UVW + ∠AWB = 180°.
Therefore,
36° + (5h - 68°) + (5h - 20°) = 180°
By simplifying this equation, we arrive at the solution: h = 28.
Thus, the value of h is 28.
A is the point with (2,9) and B is the point with coordinates (10,1) calculate the length of the line segment AB

What is the distance formula?Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively.
The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.
Learn how to apply the Pythagorean theorem to find the distance between two points using the distance formula.
The Pythagorean theorem can be rewritten as d=(((x 2-x 1)2+(y 2-y 1)2) to calculate the separation between any two locations.
So, the formula is:
d = √(x2-x1)² + (y2-y1)²
Now, insert values as follows:
d = √(x2-x1)² + (y2-y1)²
d = √(10-2)² + (1-9)²
d = √(8)² + (-8)²
d = √64+64
d = √128
d = 64 units
Therefore, using the distance formula we can conclude that the measure of line AB is 64 units.

A 210-N force is applied to the top of a piston, and the force produces 320 kPa of pressure. What is the area of the piston?
The area of the piston is 0.00065625 m².
What is the relation between force, pressure and area?A force can push or pull anything. An object can change its speed, direction of motion, or shape when a force is applied to it.
The amount of force acting on a given area is measured by its pressure.
Using the formula pressure = force area, pressure may be computed. As a result, a force exerted across a smaller area will result in more pressure.
Given that, force is applied to the top of a piston = 210N
And the force produces pressure = 320 kPa = 320,000 Pa
We know that, pressure = force/ area
So that, Area = force/ pressure
Area of Piston = 210 / 320,000 Pa
Area of Piston = 0.00065625 m²
So that The area of the piston is 0.00065625 m².

What is the equation for responsivity?
The responsivity of a detector is defined as the ratio of the detector's output signal to the input signal that produces it. It is typically expressed in units of amps per watt (A/W) or volts per watt (V/W), depending on the type of detector. The equation for responsivity is:
Responsivity = output signal / input signal
In general, the input signal is the amount of power or radiant flux incident on the detector, while the output signal is the electrical signal produced by the detector in response to the input signal.
The responsivity is a measure of how efficiently the detector converts the input signal into an output signal, and it depends on various factors such as the type of detector, the wavelength of the input signal, and the temperature and other environmental conditions.

If the data are graphed symmetrically, the distribution demonstrates 0% skewness regardless of how long or fat the tails are. When the median of a data set is utilized, 50% of the data points in the collection have values lower than or equal to the median, and 50% of them have values greater than or equal to the median. The middle score in the set is known as the median. The first step in calculating the median is to order the data points from smallest to greatest. The median in an odd-numbered set will be the value that falls exactly in the middle of the list. You must determine the average of the two middle numbers in a set of even numbers. The average is determined by summing up each value individually and dividing that sum by the total number of observations.

Line ET is tangent to circle A at T, and the measure of arc TG is 46 and the measure of O is 67°.
Tangents to circles are lines that cross the circle at a single point. Point of tangency refers to the location where a tangent and a circle converge. The circle's radius, where the tangent crosses it, is perpendicular to the tangent. Any curved form can be considered a tangent. Tangent has an equation since it is a line. A line that touches a circle just once is said to be tangent to it. A point tangent to circle can only have one tangent. The intersection of the tangent and the circle is known as the point of tangency.

The length of a living room is 12 feet and its width is 1012
feet. The length of the room is being expanded by x feet. Select all the expressions that represent the area of the living room in square feet.
Answer: The area of the living room in square feet is given by:
A = length × width
Before the expansion, the length is 12 feet and the width is 10 feet. Therefore, the initial area is:
A = 12 ft × 10 ft = 120 ft²
After the expansion, the length becomes 12 + x feet, while the width remains the same at 10 feet. Therefore, the area after the expansion is:
A = (12 + x) ft × 10 ft = 120 + 10x ft²
So, the expressions that represent the area of the living room in square feet are:
120 ft²
120 + 10x ft²
Therefore, both expressions are correct.

A boat traveling with a velocity measured in meters per second is described by the vector b = <-4, 3>. In two or more complete sentences explain how to find the speed of the boat and the direction it is traveling in standard position. In your final answer, include all of your calculations.
Step-by-step explanation:
The speed of the boat is absolute value of the velocity vector. To find the speed of the boat, take the magnitude of the velocity vector which is
[tex] \sqrt{ {a}^{2} + {b}^{2} } = {c}^{} [/tex]
Where a and b is the vector
a is -4, b is 3
so
[tex] \sqrt{16 + 9} = \sqrt{25} = 5[/tex]
So the speed of the boat is 5 meters per hour.
To find the direction of the vector, we need to find the angle it is traveling in.
Using trigonometry, we can do this.
[tex] \tan( \alpha ) = - \frac{3}{4} [/tex]
[tex]arc \tan( - \frac{3}{4} ) = \alpha [/tex]
[tex] \alpha = - 36.87[/tex]
The boat is traveling at angle 36.87 degree clockwise.
Use the IQR to determine how many outliers there are in the data set with this
Five Number Summary: 1, 2, 8, 20, 21.
a. 2
b. 3
c. 0
d. 1
===================================================
Explanation:
The five number summary is
MinQ1MedianQ3Maxin that exact order.
A five number summary of 1,2,8,20,21 means:
Min = 1Q1 = 2Median = 8Q3 = 20Max = 21The IQR (interquartile range) is the distance from Q1 to Q3
IQR = Q3-Q1
IQR = 20-2
IQR = 18
The lower fence (L) is then calculated like so
L = Q1 - 1.5*IQR
L = 2 - 1.5*18
L = -25
If any values are smaller than this lower fence of -25, then they are considered small outliers. But we know that min = 1 is the smallest value. This means we do not have small outliers.
Now onto the upper fence (U)
U = Q3 + 1.5*IQR
U = 20 + 1.5*18
U = 47
If any values are larger than 47, then they are considered large outliers. But we know that max = 21 is the largest value. This means we do not have large outliers.
In summary, all of the data values are between min = 1 and max = 21, which guarantees they are definitely in the interval between L = -25 and U = 47.
This is why there are no outliers in this data set.
