2. Please use the earliest deadline first scheduling algorithm to construct a schedule (1.e.. execution sequence) of the following task set: T1 = {2ns, Sns, Sns), Tz = {4ns, 7ns, 7ns} during a period of 22 ns. Here the notation Ti = {eu Pi, D} gives the execution time e; period P. and deadline of task t (20 points)
The schedule is as follows:
T1 -> T2 -> T1 -> T3 -> T1 -> T2 -> T1.
To construct a schedule using the Earliest Deadline First (EDF) scheduling algorithm, we need to consider the execution time, period, and deadline of each task and assign them priorities based on their deadlines. The task with the earliest deadline will be scheduled first. Let's create a schedule for the given task set:
Task T1: Execution time (e) = 2 ns, Period (P) = 5 ns, Deadline (D) = 5 ns
Task T2: Execution time (e) = 4 ns, Period (P) = 7 ns, Deadline (D) = 7 ns
Task T3: Execution time (e) = 7 ns, Period (P) = 7 ns, Deadline (D) = 7 ns
We have a period of 22 ns, and we need to schedule these tasks within that period. Let's start with the task with the earliest deadline:
At time 0 ns: Execute T1 (2 ns)
At time 2 ns: Execute T2 (4 ns)
At time 6 ns: Execute T1 (2 ns)
At time 8 ns: Execute T3 (7 ns)
At time 15 ns: Execute T1 (2 ns)
At time 17 ns: Execute T2 (4 ns)
At time 21 ns: Execute T1 (2 ns)
This completes the execution of all tasks within the given period of 22 ns. The schedule is as follows:
T1 -> T2 -> T1 -> T3 -> T1 -> T2 -> T1
In this schedule, we have followed the EDF algorithm by selecting tasks based on their deadlines. The task with the earliest deadline is always scheduled first to meet the timing requirements of the system.

The value of dimensions of a triangular prism a = 5m, dimension a = 15m and dimension c = 9m.
What is a prism?A prism is a solid form that is enclosed by plane faces on all of its sides. A prism has two different kinds of faces. Bases refer to the identical top and bottom faces. The name "prism" refers to the form of these bases. For instance, a prism is referred to be a triangular prism if its base is triangular.
The faces of a prism that are not the top and bottom are referred to as its lateral faces. The class of parallelograms also includes all the lateral faces, all of which are identical to one another.
To find the dimensions of a, b and c, we first open all the faces of prism in first figure, than we compare it with second figure, we find that,

20. The diagram shows a trapezium in which AD is
parallel to BC and angle ADC = angle BCD = 90°.
The points A, B and C are (a, 18), (12, -2) and
(2, -7) respectively.
Given that AB 2BC, find
(a) the value of a,
(b) the equation of AD,
(c) the equation of CD,
(d) the coordinates of D,
(e) the area of the trapezium.
Answer:
(a) a = 22 or 2
(b) The equations of AD are
y = x/2 + 7
or
y = x/2 + 17
(c) The equation of CD is y = -2·x - 3
(d) The coordinate of the point D is either (-8, 13) or (-4, 5)
(e) the possible areas are;
250 square units or 270 square units
Step-by-step explanation:
With only the details of the trapezium, without the drawing, we have as follows;
(a) The given points are;
A(a, 18), B(12, -2), and C(2, -7)
The length of BC is given from the formula for finding the length, l, of a line with the coordinates of the end points as follows;
\(l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}\)
\(l_{BC} = \sqrt{\left ((-7)-(-2) \right )^{2}+\left ((2)-(12) \right )^{2}} = \sqrt{\left ((-5) \right )^{2}+\left (-(10) \right )^{2}} = 5\cdot \sqrt{5}\)
∴ From \(l_{AB} = l_{BC}\), we have;
\(l_{AB}\) = 2 × 5·√5 = 10·√5
Which gives;
\(l_{AB} = \sqrt{\left ((18)-(-2) \right )^{2}+\left (a-12 \right )^{2}} = \sqrt{\left 20 \right ^{2}+\left (a-12 \right )^{2}}= 10 \cdot \sqrt{5}\)
20² + (a - 12)² = 500
(a - 12)² = 500 - 20² = 500 - 400 = 100
(a - 12)² = 100
a - 12 = ±√100 = ±10
a = 10 + 12 or -10 + 12
a = 22 or 2
(b) The equation of BC is given as follows;
The slope, m, of BC = (-7 -(-2)/(2 - 12) = -5/-10 = 1/2
The equation of BC is therefore;
y - (-7) = 1/2×(x - 2)
y + 7 = x/2 - 1
y = x/2 - 1 - 7 = x/2 - 8
y = x/2 - 8
Therefore, the slope of AD = m = 1/2
The equation of AD can be
y - 18 = 1/2×(x - 22)
y = x/2 -11 + 18 = x/2 + 7
y = x/2 + 7
or
y - 18 = 1/2×(x - 2)
y = x/2 -1+ 18 = x/2 + 17
y = x/2 + 17
(c) The equation of CD is given as follows;
CD is perpendicular to BC, therefore, the slope of CD = -1/m = -2
The equation of CD is therefore;
y - (-7) = -2×(x - 2)
y = -2·x + 4 - 7 = -2·x - 3
y = -2·x - 3
(d) The coordinate of the point D is found as follows;
At point D,
At
x/2 + 17=-2·x - 3
2.5·x = -20
x = -8
y = -8/2 + 17 = 13
or
x/2 + 7 =-2·x - 3
2.5·x = -10
x = -4
y = -4/2 + 7 = 5
The possible coordinates of the point D are (-8, 13) or (-4, 5)
(e) The area of the trapezium is found as follows;
The vertices points are;
(2, 18) or (22, 18), (12, -2), (2, -7) and (-8, 13) or (-4, 5)
The formula for the area of a trapezium = (a + b)/2×h
Length of a = \(l_{BC}\) = 5·√5
h = \(l_{CD} = \sqrt{\left ((13)-(-7) \right )^{2}+\left ((-8)-2 \right )^{2}} = \sqrt{\left 20 \right ^{2}+10^{2}}= 10 \cdot \sqrt{5}\)
or
\(l_{CD} = \sqrt{\left ((5)-(-7) \right )^{2}+\left ((-4)-2 \right )^{2}} = \sqrt{\left 12 \right ^{2}+6^{2}}= 6 \cdot \sqrt{5}\)
b = \(l_{AD} = \sqrt{\left (13-18 \right )^{2}+\left ((-8)-2 \right )^{2}} = \sqrt{\left (-5 \right )^{2}+(-10)^{2}}= 5 \cdot \sqrt{5}\)
\(l_{AD} = \sqrt{\left (5-18 \right )^{2}+\left ((-4)-22 \right )^{2}} = \sqrt{\left (-13 \right )^{2}+(-26)^{2}}= 13 \cdot \sqrt{5}\)
Therefore, the possible areas are;
(5×√5 + 5×√5)/2 × 10×√5 = 250 square units
(5×√5 + 13×√5)/2 × 6×√5 = 270 square units
The value of 'a' is 22 or 2, the equation of AD is (y = 0.5x + 17) or (y = 0.5x + 7) and the point D is (-8,13) or (-4,5) and this can be determine by using the point slope form.
Given :
The diagram shows a trapezium in which AD is parallel to BC and angle ADC = angle BCD = 90°.The points A, B, and C are (a, 18), (12, -2) and (2, -7) respectively.AB = 2 BCa) To determine the value of 'a' use the relation (AB = 2 BC).
\(\sqrt{(12-a)^2+(-2-18)^2}=2\times \sqrt{(2-12)^2+ (-7+2)^2}\)
\(\sqrt{(12-a)^2+400}=2\times \sqrt{125}\)
Squaring both sides in the above expression.
\((12-a)^2+400=4\times 125\)
\(144+a^2-24a=100\)
\(a^2-24a+44=0\)
\(a^2-22a-2a+44=0\)
\(a(a-22)-2(a-22) = 0\)
a = 2 or 22
b) The equation of BC is given by:
\(\dfrac{y+2}{x-12}=\dfrac{-7+2}{2-12}\)
\(2(y+2)=(x-12)\)
2y + 4 = x - 12
2y - x + 16 = 0
y = 0.5x - 8
Given that AD is parallel to BC so, the slope of 0.5.
First, take a = 2. The equation of line AD is given by:
\(y-18 =0.5(x-2)\)
Now, take a = 22. The equation of line AD is given by:
\(y-18 =0.5(x-22)\)
c) The line CD is perpendicular to line BC. So, the slope of line CD is -2. The equation of the line CD is given by:
y - (-7) = -2(x - 2)
y + 7 = -2x + 4
y + 2x + 3 = 0
d) The point D is given by:
0.5x + 17 = -2x - 3
2.5x = -20
x = -8
y = -4 + 17 = 13
or
0.5x + 7 = -2x - 3
x = -4
Now, y = - 2 + 7 = 5
e) Area of the trapezium is given by:
\(\rm A = L_{CD} \times L_{AD}\)
So, the possible area of the trapezium is:
\(\dfrac{(5\times \sqrt{5} +5\times \sqrt{5} )}{2}\times 10 \times \sqrt{5} = 250\)
\(\dfrac{(5\times \sqrt{5} +13\times \sqrt{5} )}{2}\times 6 \times \sqrt{5} = 270\)

Solving 2 quadratic equations we get (0,4) and (-1.1) are common points.
What are Quadratic equations?The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations.
\(Ax^2 + bx + c = 0\), where x is an unknown variable and a, b, and c are numerical coefficients, is the quadratic equation's general form. An example of a quadratic equation is \(x^2 + 2x + 1\). Here, a is greater than zero because if it equals zero, the equation will no longer be quadratic and will change to a linear equation, such as \(bx+c=0\).
As a result, we cannot refer to this equation as a quadratic equation.
Another name for the terms a, b, and c is quadratic coefficients.
Solutions of quadratic equation are called Zeroes or Roots.
Calculation:\(y=3x^2+6x+4\\y=-3x^2+5\\\)
Equating y of both equations
\(3x^2+6x+4=-3x^2+4\\6x^2+6x=0\\x(x+1)=0\\x=0,-1\)

PLEASE HELP!! what is the equation of a line that is perpendicular to y = 2x + 4 and passes through the point (4, 6)?
Answer:
The answer is B)
\(y = - \frac{1}{2}x + 8\)
Answer:
B. y = -\(\frac{1}{2}\)x + 8
Step-by-step explanation:
The line is perpendicular to line whose equation is:
y = 2x + 4 and;
passes through point (4,6) .
The product slopes of two perpendicular lines is -1.
The slope of the line whose equation is y = 2x + 4 is; 2
Let the slope of the perpendicular line (l2) be \(m_{l2}\)
\(m_{l2} * 2 = -1\)
\(m_{l2}\) = \(-\frac{1}{2}\)
Taking another point xy on line l2;
\(\frac{y - 6}{x - 4} = -\frac{1}{2}\)
Cross multiplying this gives;
y = -\(\frac{1}{2}\)x + 8 which is the equation of the perpendicular line!
write the equation of the cirlcle with diameter endpoints of (-6,3) and (-14,13)
Answer:
(x+10)² + (y-8)² = 41
Step-by-step explanation:
First, we find the length of the diameter.
from distance formula, d = SQR ROOT OF [(-14+6)² + (13-3)²]
diameter = SQR ROOT OF [8² + 10²] = √164 = √4√41 = 2√41
***** so the radius is half that, r =√41
The center of the circle is at the midpoint of the diamater.
x = (1/2)(-6 + -14) = (1/2)(-20) = -10
y = (1/2)(3 + 13) = (1/2)(16) = 8
center (h,k) = (-10,8)
circle equation: (x-h)² + (y-k)² = r²
(x- -10)² + (y - 8)² = (√41)²
(x+10)² + (y-8)² = 41

what does the activity ratio measure in the value stream
The activity ratio in the value stream measures the efficiency of the production process by evaluating the ratio of value-added activities to non-value-added activities.
The activity ratio is a performance metric used in value stream mapping, which is a lean management tool for analyzing and improving the flow of materials and information in a production process.
It focuses on distinguishing value-added activities, which directly contribute to meeting customer requirements, from non-value-added activities, which do not add value but consume resources and time.
By calculating the activity ratio, organizations can assess the proportion of time and resources spent on value-added activities versus non-value-added activities.
A higher activity ratio indicates that a greater portion of resources is dedicated to value-added activities, indicating improved efficiency and reduced waste.
Conversely, a lower activity ratio suggests a higher proportion of resources being utilized for non-value-added activities, indicating potential areas for improvement and waste reduction.
The activity ratio serves as a valuable diagnostic tool for organizations to identify process inefficiencies, bottlenecks, and areas for improvement. By analyzing the activity ratio, organizations can streamline their processes, eliminate waste, and optimize resource allocation to enhance overall productivity and customer value.

suppose you are tossing a coin and it comes up heads five times in a row. the idea that the chance that the next coin toss will be heads must be very small, since that would imply six times if a row, and the odds of 6 heads in a row is 1/64, is an example of?
The Law of Large Numbers, which states that as the number of trials increases, the observed probability will get closer and closer to the expected probability.
This is an example of the Law of Large Numbers. The Law of Large Numbers states that as the number of trials (in this case, the number of coin flips) increases, the observed probability (in this case, the probability that the next coin flip will be heads) will get closer and closer to the expected probability (in this case, 50%). The formula for this is P(n) = P(1) + (P(n) - P(1))/n, where n is the number of trials and P(1) is the probability of the first trial.
For example, if the first coin flip results in heads (P(1) = 1), the probability of the 5th coin flip being heads is P(5) = 1 + (0.5 - 1) / 5 = 0.2. This means that the probability of the 6th coin flip being heads is 0.2 + (0.5 - 0.2) / 6 = 0.3125, or 1/64.

\(\displaystyle = (x^2 + 2x^2 +3x^2) + (xy - 6xy -3xy) + (-6 -1 + 7 )\)
And combine like terms. Hence:
\(\displaystyle A - B + C = 6x^2 -8xy\)
III)
We want to find:
\(\displaystyle A + B - C\)
Substitute:
\(\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) - (3x^2 + 7 - 3xy)\)
Distribute:
\(\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) + (-3x^2 - 7 + 3xy)\)
Rewrite:
\(\displaystyle = (x^2 - 2x^2 - 3x^2) + (xy +6xy +3xy) + (-6 +1 - 7)\)
And combine like terms. Hence:
\(\displaystyle A + B - C= -4x^2 + 10xy -12\)
a highway has an optional toll lane that drivers may take to reduce the time they spend driving. drivers pay a small fee to enter the toll lane ($0.25) . then, once they leave the toll lane, they pay a fee based on the number of miles they have traveled on the toll lane. assume that the driver may leave the lane after any whole number of miles and pays for exactly that number, without rounding up. note that there is a linear relationship between the number of miles a vehicle has traveled and the price of the toll. a. if frank is on the toll road for 4.00 miles and then leaves the lane, how much will he have to pay total for the trip?
He have to pay $3.25.
Let the number of miles traveled by a driver be x
The toll paid by the driver is then represented as y. (in dollar)
Linear equation : an equation in which there is only one variable present. It is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution.
Since there is a linear relation between the two, we can assume the equation can be written as:
y = mx + c
From the given data, we get
0.24 = m(0) + c
c = 0.25
Using the second point:
1 = m(1) + 0.25
m = 1 − 0.25 = 0.75
Hence, the equation is y = 0.75x + 0.25.
If x = 4, then:
y = 0.75 × 4 + 0.25
y = 5.50
Hence, He have to pay $3.25.

Is 33 a prime number? Explain why or why not
Answer:
No
Step-by-step explanation:
It is not a prime number because it is divisible by 1, 3, 11 and itself, 33.
If it were just 33 and 1, it would be prime, but it has those extra factors
I’ve been stuck on this for a few minutes. I’m not really sure what to do..
Answer:
Step-by-step explanation:
You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.
You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.
That leaves you with one unknown angle. ? = 180°-40°-55° = 85°

If $y>0$, find the range of all possible values of $y$ such that $\lceil{y}\rceil\cdot\lfloor{y}\rfloor
Range is R={n^2: n is natural number} U {n(n+1) : n is natural number}
The expression ⌈y⌉⋅⌊y⌋ represents the product of the ceiling and floor functions of y.
To find the range of all possible values of y, we need to consider the possible values of the ceiling and floor functions individually.
1. Ceiling function (⌈y⌉): This function rounds y up to the nearest integer. Since y is greater than 0, the ceiling of y will always be greater than or equal to y.
2. Floor function (⌊y⌋): This function rounds y down to the nearest integer. Again, since y is greater than 0, the floor of y will always be less than or equal to y.
Now, let's consider the product of the ceiling and floor functions, ⌈y⌉⋅⌊y⌋.
The product ⌈y⌉⋅⌊y⌋ will always be greater than or equal to 0 since y > 0 and this can take only integral values.
Therefore, the range of all possible values of y such that ⌈y⌉⋅⌊y⌋ is the set R={n^2: n is natural number} U {n(n+1): n is natural number}

If 16*x=1/64, find the value of x
Answer:
I think it is x=1/1024 not sure but try it
Answer:
x = - \(\frac{3}{2}\)
Step-by-step explanation:
Assuming you mean
\(16^{x}\) = \(\frac{1}{64}\)
note that 16 = 4² and 64 = 4³ , so
\((4^{2} )^{x}\) = \(\frac{1}{4^{3} }\)
\(4^{2x}\) = \(4^{-3}\)
Since the bases on both sides are equal, both 4, then equate exponents
2x = - 3 ( divide both sides by 2 )
x = - \(\frac{3}{2}\) ( = - 1.5 )
a saving account earns interest at a rate of 7% each month. the initial balance is $100. write an exponential function b(m) to model the growth after m months.
Data:
Initial balance: c
intrest rate: r
time (months)=m
growth: b
c=$100
r=7%=0.07
To an exponential function you have the next general form:
\(y=C(1+r)^t\)In this case
y=b(m)
C=c
r=r
t=m
\(b(m)=100(1+0.07)^m\)
