Use the method of corners to find the point(s) that minimize the objective function C=2x+12y given the following constraints. Label your lines and mark the feasible region with an S. 2x+12y 60 x+y 20 x>0, y20
Answers
The function C = 2x + 12y, has minimum value 60 at points (18,2) and (30,0).
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The given objective function -
C = 2x + 12y
Subjected to the constraints -
2x + 12y ≥ 60
x + y ≥ 20
x ≥ 0, y ≥ 0
First consider the inequality 2x + 12y ≥ 60.
The equation of the above inequality is as follows -
2x + 12y = 60
Find two points that satisfies the above equation.
Take x = 6, then -
2(6) + 12y = 60
12 + 12y = 60
12y = 60 - 12
12y = 48
y = 4
The first point is (6,4).
Take x = 0, then -
2(0) + 12y = 60
0 + 12y = 60
12y = 60
y = 5
The second point is (0,5).
Substitute (x,y) = (0,0) and see the direction of the region for 2x + 12y ≥ 60.
2(0) + 12(0) ≥ 60
0 ≥ 60
This is not true.
Therefore, the region is non-origin side.
Now consider the inequality x + y ≥ 20.
The equation of the above inequality is as follows -
x + y = 20
Find two points that satisfies the above equation.
Take x = 0, then -
0 + y = 20
y = 20
The first point is (0,20).
Take y = 0, then -
x + 0 = 20
x = 20
The second point is (20,0).
Substitute (x,y) = (0,0) and see the direction of the region for x + y ≥ 20.
0 + 0 ≥ 20
0 ≥ 20
This is not true.
Therefore, the region is non-origin side.
Plot the graph.
From the graph see that the corner points are (0,20), (18,2) and (30,0).
Now plug these points in the objective function and see for which point the objective function has the minimum value.
C = 2x + 12y
C = 2(0) + 12(20)
C = 0 + 240
C = 240
C = 2(18) + 12(2)
C = 36 + 24
C = 60
C = 2(30) + 12(0)
C = 60 + 0
C = 60
Therefore, the minimum value 60 is at points (18,2) and (30,0).

t is the parameter, n is the unit normal vector, and κ is the curvature of the space curve.
To find t, n, and κ for the space curve r(t)=-ti-(a cos h (t/a))j, first calculate the position vector r, which is r(t)=-ti-(a cos h (t/a))j. Then, calculate the derivative of the position vector to find the tangent vector t, which is t=i+(t/a)sin h(t/a)j. Next, calculate the second derivative of the position vector to find the normal vector n, which is n=(-(1/a) sin h(t/a))i+(1/a2)(cos h(t/a))j. Lastly, calculate the curvature κ by dividing the magnitude of the second derivative of the position vector by the square of the magnitude of the first derivative, which is κ=(1/a2)(cos h(t/a))/(1+(t/a) sin h(t/a))2.

Answers
The number of divisors of 1730 of the form 4n + 1 is 20.
What do you mean by integers?An integer is a whole number, meaning it can be positive, negative, or zero, but it cannot be a fraction or a decimal. Integers are a subset of real numbers, which also include fractional and decimal numbers.
Integers are commonly used in mathematics and computer science for counting and for performing arithmetic operations such as addition, subtraction, multiplication, and division. They are also used to represent the magnitude of a quantity, such as the number of items in a set or the time elapsed in seconds.
In computer programming, integers are often stored as binary numbers, which are sequences of bits that represent positive or negative whole numbers. Different computer architectures have different numbers of bits for representing integers, with common sizes being 8, 16, 32, and 64 bits.
The number (10)10. (11)11. (13)13 is equal to 11 × 13 × 10 = 1730 in decimal.
A divisor of a number can be represented as (4n + 1) where n is a non-negative integer.
To find the number of divisors of 1730 of the form 4n + 1, we need to find the number of factors of 1730 that can be expressed as 4n + 1.
First, we find the prime factorization of 1730:
1730 = 2 × 3 × 5 × 29
Since 1730 is an odd number, one of its divisors must also be an odd number.
The only possible values for n are 0, 1, 2, ..., (number of odd divisors - 1).
In this case, the number of odd divisors of 1730 can be calculated as:
(number of ways to choose 0 odd factors) × (number of ways to choose 1 odd factor) × (number of ways to choose 2 odd factors) × ... × (number of ways to choose 4 odd factors)
= 1 × 4 × 5 × 1 = 20
Thus, the number of divisors of 1730 of the form 4n + 1 is 20.

Two students missed the first Mid exam. Their excuse was that their car had gotten a flat tire. On the next mid exam, these students were asked to identify which tire had become flat (driver's side front, driver's side rear, passenger's side front, passenger's side rear). What is the probability that the two students pick the same tire (assuming the students are randomly choosing)? Submit your answer as a decimal with four digits of accuracy.
Answers
Answer:
1/4=0.25
Step-by-step explanation:
The probability that both students pick the same tire is (1/4) * (1/4) = 1/16
The probability of the first student picking a specific tire is 1 in 4, or 1/4. The probability of the second student also picking that same tire is also 1 in 4. To find the probability that both students pick the same tire, we need to multiply the probabilities of each event.
So, the probability that both students pick the same tire is (1/4) * (1/4) = 1/16. This means that the chance of both students picking the same tire is 0.0625 or 6.25%.
To summarize, there are four possible tires that could have gotten a flat, and two students are asked to identify the tire. If each student randomly chooses a tire, the probability that both students will pick the same tire is 1 in 16, or 0.0625. This means that the chance of both students picking the same tire is low, and the likelihood of them choosing different tires is much higher.

Answers
The intersection of this sphere with the -plane is (y+6)²+(z-4)²=21
The equation of a sphere centered at (h,k,l) and radius r is given by:
(x−h)²+(y−k)²+(z−l)²=r²
where x,y, and z represent the coordinates of the points on the surface of the surface.
so if the center is (-3,2,5) and radius r=4 then we can plug the values in the above formula:
consider the points h=-3 k=2 l=5 and r=4.
(x−(-3))²+(y−2)²+(z−5)²=4²
(x+3)²+(y−2)²+(z−5)²=16.
If the sphere intersects the yz-plane then x=0
The resulting equation is an equation of a circle with a radius r=√21
and at the center with (6,-4) on the yz-plane
with yx-plane:
⇒(x−2)²+(y+6)²+(z−4)²=25
⇒ (0−2)²+(y+6)²+(z−4)²=25
⇒4+(y+6)²+(z−4)²=25

Answer: 10 yards is equivalent to 30 feet.
Step-by-step explanation:
In 30 feet, there are 10 yards. Therefore 3 feet are equal to 1 yard. To precisely calculate the length in feet, divide 4 yards by 3.
How are yards calculated using dimensions?Let's now convert each of the three dimensions to a yard. How to do it is as follows: Convert the measurement from inches to yards (6 x 36 = 0.167 yards). Do the math to convert 12 feet x 3 into 4 yards. The square yard is equal to the length times the width, expressed in feet, multiplied by 9. (SQYDS).A square yard measures 9 square feet. The area value must be multiplied by 9. You don't need much to change an area from square feet to square yards. For instance, you might divide 27 square feet by 9 to get square yards.Add three to the total number of yards.
Add 10 to 3 since 3 feet are equivalent to 1 yard.

At what point on the curve x = 3t^2 + 5, y = t^3 − 7 does the tangent line have slope 1/2 ?
Answers
The tangent line on the curve x = 3t² + 5 , y = t³ - 7 have a slope as 1/2 at the point (8, -6).
The Tangent Line to a curve at a specific point is calculated by the derivative of the curve at that point.
The Slope of the tangent line at a point (x₀, y₀) is given by the derivative of the curve at that point, denoted as f'(x₀).
The curve x = 3t² + 5 , y = t³ - 7 ,
we have to find the value of t such that the slope of the tangent line at that point is 1/2.
we first find the derivative of y with respect to x, which is given by:
⇒ dy/dt = 3t² and dx/dt = 6t
Using chain rule to find the derivative of y with respect to x:
⇒ dy/dx = dy/dt × dt/dx = (3t²)/6t = t/2
Next, we equate derivative to 1/2 and solve for t ;
⇒ t/2 = 1/2
⇒ t = 1
So, the point where the tangent line has slope 1/2 is
⇒ (x, y) = (3t² + 5, t³ - 7)
⇒ (8, -6).
Therefore , the point is (8,-6) .

Answers
After three days Thurber will have studied the same total amount of time for both math and science and the time is 165 minutes for both.
How do you find the time in math?Time can be described in mathematics as an ongoing and continuous series of events that take place one after another, from the past through the present, and into the future. The duration of events or the gaps between them can be measured, compared, or even ordered using time.The equation for calculating time is [Time = Distance ÷ Speed].Seconds, minutes, hours, days, weeks, months, and years are the fundamental units of time. To determine the time of day, we use seconds, minutes, and hours; to determine the date, we use days, months, and years. The smallest units of time are seconds, minutes, and hours, while the larger ones are days, months, and years.Given data :
Today, he studies 15 minutes math and 75 minutes science and from now on, 50 minutes math and 30 minutes science. So if he studies for 1 day total time for math and science will be:
Math = 15 + 50 = 65
Science = 75 + 30 = 105
2nd day:
Math = 65 + 50 = 115
Science = 105 + 30 = 135
3rd day:
Math = 115 + 50 = 165
Science = 135 + 30 = 165
So, after three days Thurber will have studied the same total amount of time for both math and science and the time is 165 minutes for both.

What is linear equation ?
A linear equation is an algebraic equation with simply a constant and a first-order (linear) term of the form y=mx+b, where m is the slope and b is the y-intercept. The above is sometimes referred to as a "linear equation with two variables," where y and x are the variables.
To check whether the point (2, 11) is a solution to the system, we need to substitute these values into both equations and see if they hold true.
For equation 1:
-2 * 2 + 5 * 11 = -4 + 55 = 51
For equation 2:
-7 * 11 = -77
-61 - 8 * 2 = -61 - 16 = -77
Since both equations are true for the given point, the statement "The point satisfies both equation 1 and 2" is correct and "The point is a solution to the system" is also correct.
Therefore, the correct statements from the group of answer choices are:
The point satisfies both equation 1 and 2
The point is a solution to the system

Answer: C. 12000(1.05)^n < 20000
Step-by-step explanation:
When it says that the tuition is increasing at a rate of 5%, it means that you add 1
1+0.5= 1.05
Everything else is the same so you just add 1 to 0.5 and that is the answer.
The dog shelter has Labradors, Terriers, and Golden Retrievers available for adoption. If P(terriers) = 15%, interpret the likelihood of randomly selecting a terrier from the shelter.
Likely
Unlikely
Equally likely and unlikely
This value is not possible to represent probability of a chance event
Answers
The interpretation that the likelihood that the first question will be true is (a) Likely.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
To interpret the likelihood that the first question will be true.
From the question, we have the following parameters that can be used in our computation:
Probability value
The value of the probability and the notation are given as
P(true) = 0.8
As a general rule of probability, we have
Range of probability value = 0 to 1 (inclusive)
Unlikely = less than 0.5
Equally likely and unlikely = 0.5
Likely = greater than 0.5
Using the above as a guide, we have the following:
The value of P(true) = 0.8 is greater than 0.5
This that the probability is likely

Estimate the indicated probability by using the normal distribution as an approximation to the binomial distribution. Estimate p(6) for n = 18 and p = 0. 3.
Answers
By applying normal approximation to the binomial concept, it can be concluded that the indicated probability is 0.62134
Normal approximation to the binomial is a method of approximating the probabilities associated with the binomial distribution using the normal distribution.
μ = n.p
σ = √np(1-p)
where μ is the mean, n is the number of trials, p is the success probability and σ is the standard deviation.
Now we have:
x = 6
n = 18
p = 0.3
Thus we can calculate the mean:
μ = np
= 18 * 0.3
= 5.4
Now we calculate the standard deviation
σ = √μ (1-p)
= √ 5.4 (1 - 0.3)
= √ 5.4 * 0.7
= √ 3.78
= 1.944
Then we can find the z-score using the mean and standard deviation found in the previous step:
z-score = (x – μ) / σ
= (6 - 5.4) / 1.944
= 0.6 / 1.944
= 0.309
And finally, we can obtain from the z table that P(6) = P(x<0.309) = 0.62134
