An engineering student is studying the effects of cryogenic treatments on a particular material. The treatment involves cooling the material with specific applications of liquid nitrogen.
The temperature of the material in degrees Celsius, y, can be modeled by the following graph, where x represents the time, in hours, since the treatment began.
The true statement about the graph from the attached image below is: The material's temperature reaches a minimum at 15 hours.
What is the parabolic graph of the quadratic equation?The parabolic graph is a curved U-shaped graph that is established from a quadratic equation.
The parabola of the graph can be downward creating a maximum or upward (minimum).
From the given image, the correct interpretation shows that as a result of cryogenic treatment, the material's temperature reaches a minimum at 15 hours.

What is the most picked number between 1 and 10?
The most picked number between 1 and 10 is statistically 7.
"Most picked number" generally refers to the number that is most frequently chosen or selected.
It is difficult to determine the value in general without any specific context or situation.
However, statistically speaking, the number 7 is often considered the most popular choice. This is because it is considered a lucky number in many cultures and is also a common choice for people who do not have a specific number in mind.
Nevertheless, it's important to note that this may not always be the case and can vary depending on the context or situation as the probability of picking each number is equally likely (0.1).

to use a binomial distribution to approximate the count of successes in an srs, why do we require that the sample size n be no more than 10% of the population size n?
When the 10% criterion is met, we can use a binomial distribution to approximate the number of successes in a simple random sample (SRS) (as a simple random sample selects the trials without replacement).
The sample must be less than 10% of the population in order to satisfy the 10% requirement. It is fair to presume that the trials are independent because the sample is so much smaller than the population (even though the sampling occurred without replacement).
This suggests that the sample size n in this situation must be less than 10% of the population size NN.
This is the reason why 10% condition should be met.
In a binomial probability distribution, the number of successes in a series of n experiments is represented as either success or failure (probability q = 1 p), depending on the outcome's boolean value. A Bernoulli trial or experiment is another name for a single success or failure test, while a Bernoulli process is another name for a sequence of results.

Step-by-step explanation:
Change from rectangular to cylindrical coordinates. (Let r ≥ 0 and 0 ≤ θ ≤ 2π.) (a) (−9, 9, 9) (b) (−8, 8 3 , 5)
(a) Cylindrical coordinates for (a): (r, θ, z) = (√162, 3π/4, 9)
(b) Cylindrical coordinates for (b): (r, θ, z) = (√256, 4π/3, 5)
Cylindrical coordinates can be defined as three sets of coordinates used to locate a point in a cylindrical coordinate system. In two dimensions, the position of a point can be expressed in Cartesian and polar coordinates. When polar coordinates are extended to the 3D plane, an additional coordinate is added. Together, these three measurements form cylindrical coordinates. Coordinates define both distance and angle.
The radial distance, azimuth, and height of the plane from a point are expressed in cylindrical coordinates. Cylindrical-coordinate systems can be used to describe systems with rotational symmetry.
To convert from rectangular coordinates to cylindrical coordinates, we use the following equations:
r = sqrt(x^2 + y^2)
theta (θ) = arctan(y/x)
z = z
For part (a), we have the rectangular coordinates (-9, 9, 9). Using the above equations, we get:
r = sqrt((-9)^2 + 9^2) = 9 sqrt(2)
theta = arctan(9/-9) = -π/4 (since the point is in the third quadrant)
z = 9
So the cylindrical coordinates for part (a) are (9 sqrt(2), -π/4, 9).
For part (b), we have the rectangular coordinates (-8, 8 sqrt(3), 5). Using the above equations, we get:
r = sqrt((-8)^2 + (8 sqrt(3))^2) = 16
theta = arctan(8 sqrt(3)/-8) = -π/3 (since the point is in the third quadrant)
z = 5
So the cylindrical coordinate for part (b) is (16, -π/3, 5).

If there are 2.54 cm in 1 inch how long is a 36 inch long measuring stick in cm
Answer: The answer is 91.44 centimeters/cm
Step-by-step explanation:
2.54*36= 91.44 centimeters/cm
A 36-inch long measuring stick is equivalent to 91.44 cm.
To convert inches to centimeters, we can use the conversion factor:
1 inch = 2.54 cm
To find out the length of a 36-inch measuring stick in centimeters,
we multiply the length in inches by the conversion factor:
36 inches x 2.54 cm/inch
= 91.44 cm
Therefore, a 36-inch long measuring stick is equivalent to 91.44 cm.

Find the surface area of the regular pyramid
find the exact values of the sine, cosine, and tangent of the angle. 255° = 300° − 45°
The exact values of the sine, cosine, and tangent of the angle 255° are -1/√2, 1/√2, and -1, respectively.
To find the exact values of the sine, cosine, and tangent of the angle 255°, we can use the identity that relates the trigonometric functions of an angle to the trigonometric functions of its complement.
By expressing 255° as the sum of 300° and -45°, we can determine the exact values of the trigonometric functions for the given angle.
We know that the sine, cosine, and tangent of an angle are periodic functions, repeating every 360 degrees. To find the exact values of the trigonometric functions for 255°, we can express it as the sum of 300° and -45°, where 300° is a multiple of 360°.
Since the sine, cosine, and tangent functions are odd or even functions, we can use the values of the trigonometric functions for 45° to determine the values for -45°.
For 45°:
sin(45°) = cos(45°) = 1/√2
tan(45°) = 1
Since cosine is an even function, cos(-45°) = cos(45°) = 1/√2.
Since sine is an odd function, sin(-45°) = -sin(45°) = -1/√2.
Using the definition of tangent as the ratio of sine to cosine, tan(-45°) = sin(-45°) / cos(-45°) = (-1/√2) / (1/√2) = -1.
Therefore, for the angle 255°:
sin(255°) = -1/√2
cos(255°) = 1/√2
tan(255°) = -1

Triangle JKL is an equilateral triangle with two of its vertices at points J and K. What are the coordinates of point L? Round to the nearest tenth as needed.
Answer:
(6, 7.2)
Explanation:
Since it is an equilateral triangle, all of the side lengths must be equal.
Therefore, we know the lengths JK = 6 and JL = 6. If h is the height of the triangle, the Pythagoras's theorem says
\((\frac{JK}{2})^2+h^2=JL^2\)putting in the values of JK and JL gives
\((\frac{6}{2})^2+h^2=6^2\)\(3^2+h^2=6^2\)subtracting 3^2 from both sides gives
\(h^2=6^2-3^2\)\(h^2=27\)Taking the square root of both sides gives
\(h=3\sqrt[]{3}\)or in decimal form rounded to the nearest tenth
\(h=5.2\)With the value of h in hand, we can now read off the coordinates of L.
The x coordinate of L is 6 (count the boxes along the x-axis until you are under L or halfway between J and K).
The y-coordinate of L is 2 + h = 2 + 5.2 = 7.2 ( how far above the x-axis the traingle is plus the height of the triangle ).
Hence, the coordinates of the point L are (6, 7.2).
