The exposure time when x = 560 is: 13.66 hour
What is quadratic model?A method of simulating the relationship between two sets of variables is quadratic regression. The outcome is a regression equation that may be applied to the data to generate predictions. The formula for the equation is: y = ax² + bx + c, where a ≠ 0. Situations that may be approximated by quadratic functions include tossing a ball, firing a cannon, jumping from a platform, and striking a golf ball. Researchers may find the quadratic model to be a useful tool for data analysis in identifying the combined impact of success objectives on academic accomplishment. We anticipate that future studies on the impact of academic performance objectives will frequently use the quadratic model to analyse their data.
Given that,
T = 0.0002x² - 316x + 127.9
exposure time = T
Now, calculate exposure time when x = 560
So, T = 0.0002x² - 0.316x + 127.9
T = 0.0002×(560)² - 0.316 × (560) + 127.9
T = 62.72 - 176.96 + 127.9
T = 13.66 hour

Andrew and Sebastian are training for a weightlifting competition. In order to prepare, each of them has created their own personal training pian asidious
• Andrew will start off by lifting 50 pounds and will increase the weight he fifts by 10% each week
Sebastian will start off by lifting 40 pounds and will increase the weight he lifts by 10 pounds each week
Andrew's training plan can be modeled by an exponential function, and Sebastian's training plan can be modeled by a linear function. So, correct option is c) .
Describe Linear Function?A linear function is a mathematical function that maps a set of inputs to a set of outputs in such a way that the output is proportional to the input. In other words, if the input changes by a certain amount, the output changes by a constant factor.
The equation of a linear function has the form:
y = mx + b
where x is the input variable, y is the output variable, m is the slope of the line, and b is the y-intercept. The slope represents how much the output changes for each unit change in the input, and the y-intercept represents the output value when the input is zero.
Linear functions are represented by straight lines on a graph. If you plot the input and output values for a linear function on a graph, the resulting points will form a straight line. The slope of the line represents the rate of change of the output with respect to the input, and the y-intercept represents the initial value of the output.
In Andrew's training plan, the weight he lifts is increasing by a constant percentage each week, which is characteristic of exponential growth. In Sebastian's training plan, the weight he lifts is increasing by a constant amount each week, which is characteristic of linear growth.

an without replacement, what is the probability that the first 2 selected are white and the last 2 black?
There is a 0.99% chance of getting the first 2 white and the last 2 black if you draw 4 balls without replacement from a bag containing 10 white and 20 black balls.
If there are W white balls and B black balls in a bag, and you are drawing 4 balls without replacement, the probability that the first 2 selected are white and the last 2 black can be calculated as follows:
[tex]P(WWBB) = (W/ (W + B)) * ((W-1) / (W + B - 1)) * (B / (W + B - 2)) * ((B-1) / (W + B - 3))[/tex]
So, for example, if there are 10 white balls and 20 black balls, then the probability of getting the first 2 white and the last 2 black is:
[tex]P(WWBB) = (10 / 30) * (9 / 29) * (20 / 28) * (19 / 27) = 0.0099[/tex]
This means that there is a 0.99% chance of getting the first 2 white and the last 2 black if you draw 4 balls without replacement from a bag containing 10 white and 20 black balls.

if a triangle is other side is 7m and other side is 12m what is the other side going to be
If a triangle has one side of 7 meters and another side of 12 meters, the other side is approximately 13.928 meters long.
A triangle is a three-sided polygon that has three angles and three sides. The sides of a triangle are connected by its angles, and the sum of the angles of a triangle is always equal to 180 degrees. The length of the sides of a triangle affects the size of its angles, and the size of its angles affects the length of its sides.
Now, in the case of a triangle where one side is 7 meters and another side is 12 meters, the length of the third side can be calculated using the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Mathematically, it can be written as
=> a² + b² = c²,
where a and b are the lengths of the two sides, and c is the length of the hypotenuse.
Using the Pythagorean theorem, we can find the length of the third side of the triangle. Let's call the length of the third side "x". So,
=> x² = 7² + 12² = 49 + 144 = 193.
Taking the square root of both sides, we get
x = √(193) = 13.928.
So, the third side of the triangle is approximately 13.928 meters long.

A plane, 50 miles away from its destination, is flying toward the airport at an altitude of 30,500 feet. Later, this same plane is 20 miles from the airport and has descended to an altitude of 18,000 ft.
How far has the plane flown?
Answer:
In feet: [tex]\boxed{158,892 \textrm{ feet}}[/tex]
In miles: [tex]\boxed{\textrm{ 3.11 \;miles}}[/tex]
Step-by-step explanation:
A diagram really helps here and so I have drawn one for your understanding
From the diagram we see that Point A refers to the location of the plane when it is 50 miles away from the airport at am altitude of 30,500 feet
In a 2D coordinate system where x refers to the horizontal distance from the airport value and y refers to the altitude,
=> Point A has coordinates (50, 30500)
When the plane is 20 miles away from the airport, the altitude has dropped down to 18000 feet
This location is represented as point B(20, 18000)
The horizontal distance traveled by the plane is 50 - 20 = 30 miles
The vertical distance traveled by the plane(drop in altitude) is 30,500 - 18,000 = 12, 500
These two form the legs of a right triangle with the actual path of descent as the hypotenuse of the right triangle (see figure)
The distance c traveled by the plane is the distance from Point A to Point B which can be computed using the Pythagorean theorem given the two legs of the right triangle
The general formula is :
[tex]\mbox{\large c = \sqrt{a^{2} + b^{2}}}[/tex]
where c is the length of the hypotenuse, a and b are the lengths of the other two sides
We have a = 12, 500 feet and b = 30 miles
Convert miles to feet to get same units:
a = 12, 500 feet
b = 30 miles = 30 x 5280 feet = 158400
[tex]\mathbox{ c = \sqrt{158400^{2} + 12500^{2}}}[/tex]
[tex]c = \sqrt{25090560000 + 156250000}[/tex]
[tex]c = \sqrt{25246810000}[/tex]
[tex]\mathrm{c = 158,892.45 \;feet}\\[/tex]
[tex]\mathbox{ \textrm{c = 158,892 feet (to the nearest foot)}}[/tex]
So the distance traveled by the plane is 158, 992 feet (to the nearest foot)
This works out to 158992/5280 miles = 30.11 miles which is pretty close to 3.09
Maybe you are required to answer in feet and not in miles.

Let Y be the discrete random variable that counts the number of face cards in a seven-card hand drawn from a standard 52-card deck. The possible values for Y are 0, 1, 2, 3, 4, 5, 6, and 7.
The number of ways to get Y face cards in a seven-card hand is given by the binomial coefficient C(7, Y), where C(7, Y) represents the number of combinations of 7 things taken Y at a time.
The probability of getting Y face cards in a seven-card hand is given by:
[tex]P(Y) = (C(7, Y) * (12/52)^Y * (40/52)^{(7-Y)} /C(7, 52)[/tex]

Answer:
Non-linear
Step-by-step explanation:
y = 10/x is non-linear!
Because a linear equation is an equation of a straight line, which means the degree of a linear equation must be 0. In this case, the degree of variable y is 1; the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not linear.

None. The discriminant of the quadratic equation is [tex]b^{2}[/tex]-4ac = [tex]11^{2}[/tex] - 4(1)(18) = 121 - 72 = 49, which is not a perfect square.
What is perfect square ?A perfect square is a number that can be expressed as the product of two equal integers. For example, 9 is a perfect square because it can be written as 3 x 3.
The zeros of this quadratic function can be found by setting the equation equal to 0 and solving for x.
0 = [tex]x^{2}[/tex] + 11x + 18
To solve for x, we can use the quadratic formula:
x = [-b ± √([tex]b^{2}[/tex] - 4ac)]/2a
Substituting in our values from the equation above, we get:
x = [-11 ± √([tex]11^{2}[/tex] - 4(1)(18))]/2(1)
x = [-11 ± √(-63)]/2
Since the square root of a negative number is not a real number, there are no zeros.
Therefore, the answer is None.

Use superposition to find vo in the given circuit where i1 = 6 a and i2 = 4 a
the voltage across the circuit ([tex]V_{0}[/tex]) is 80 volts.
In the superposition theorem, the voltage across any element in a linear circuit is equal to the sum of the voltages caused by each source acting independently. In other words, in a linear circuit, each source is treated as the only source, and the other sources are replaced with their internal resistances.
With the resistance value of 8 ohms, we can calculate the voltage across the circuit using the superposition theorem.
First, consider [tex]I_{1}[/tex] as the only source, and set [tex]I_{2} = 0 A[/tex]. The voltage across the circuit can be found using Ohm's law (V = IR), where R is the resistance in the circuit.
[tex]V_{1} = i1 * R = 6 A * 8 ohms = 48 V[/tex]
Next, consider [tex]I_{2}[/tex] as the only source, and set [tex]I_{1} = 0 A[/tex]. The voltage across the circuit can be found using Ohm's law (V = IR), where R is the resistance in the circuit.
[tex]V_{2} = i2 * R = 4 A * 8 ohms = 32 V[/tex]
Finally, the voltage across the circuit ([tex]V_{0}[/tex]) is the sum of the voltages found in steps 1 and 2.
[tex]V_{0} = V_{1} + V_{2} = 48 V + 32 V = 80 V[/tex]
