The correct answer is (d) all of these. when ls1 is actuated and ls2 is not, all the rungs of the program will be evaluated, and as a result, all the output conditions will be true.
In the given ladder logic program, when ls1 is actuated and ls2 is not, all the rungs of the program will be evaluated from left to right and top to bottom to determine the output conditions.
Looking at the program, we see that if ls1 is actuated, it will turn on the output O:2/5 and set the latch L1. Then, in the second rung, if ls2 is not actuated, it will turn on the output O:2/6 and set the latch L2. Finally, in the third rung, if both ls1 and ls2 are not actuated and both latches L1 and L2 are set, it will turn on the output O:2/7.
Therefore, when ls1 is actuated and ls2 is not, all the rungs of the program will be evaluated, and as a result, all the output conditions will be true. Hence, all of the following statements are true:
a) pilot light pl1 (o:2/5) is on.
b) pilot light pl2 (o:2/6) is on.
c) pilot light pl3 (o:2/7) is on.
Therefore, the correct answer is (d) all of these.

Consider the equations y = 2x - 3 and y = 3x - 6. Solve the system of equations by completing the table to find an ordered pair that satisfies both equations.
A) (0, 3)
B) (1, -1)
C) (2, 2)
D) (2, 2)
Answer:
2,2
Step-by-step explanation:
Equations are all good
The ordered pair (2, 1) satisfies the given equations. Therefore, the answer is option (C).
To solve the system of equations y = 2x - 3 and y = 3x - 6, we need to find an ordered pair (x, y) that satisfies both equations.
We can do this by completing the table of values for each equation and finding the values of x and y that make both equations true.
For the equation y = 2x - 3, we can complete the table as follows:
x: -1, 0, 1, 2, 3
y: -5, -3, -1, 1, 3
For the equation y = 3x - 6, we can complete the table as follows:
x: -1, 0, 1, 2, 3
y: -9, -6, -3, 0, 3
From these tables, we can see that the ordered pair (2, 1) satisfies both equations.
Therefore, the answer is (2, 1).

Bella begins to walk from her house toward her friend Ella's house. At the same time, Ella begins to ride her bicycle toward Bella's house. They each maintain a constant speed, and Ella rides 5 times as fast as Bella walks. The distance between their houses is 2 miles, which is 10,560 feet, and Bella covers $2\frac{1}{2}$ feet with each step. How many steps will Bella take by the time she meets Ella
Since Bella takes 4,224 steps, and Ella takes 844.8 steps, they meet at 4,224 steps.
To determine this:
We can start by using the information given to find out how long it takes Bella and Ella to meet.
Since Ella rides 5 times faster than Bella walks, we can use the following equation to find out how long it takes each of them to cover the 2-mile distance:
Time (Ella) = Time (Bella) / 5
We can also use the distance formula to find out how long it takes Bella to cover the 2-mile distance:
Distance = Speed x Time
We know that Bella's speed is \($2\frac{1}{2}$\) feet per step, and the distance between their houses is 10,560 feet. So:
10,560 feet = \($2\frac{1}{2}$\) feet/step x Time (Bella)
Solving for Time (Bella), we get:
Time (Bella) = 10,560 feet / \($2\frac{1}{2}$\) feet/step = 4,224 steps
Now we can use this information to find out how long it takes Ella to meet Bella:
Time (Ella) = Time (Bella) / 5 = 4,224 steps / 5 = 844.8 steps
And since Bella takes 4,224 steps, and Ella takes 844.8 steps, they meet at 4,224 steps.

Find the measure of angle 6.
Answer:
m∠6 = 116°
Step-by-step explanation:
first find x:
7x - 17 = 2x + 78
subtract 2x from both sides: 5x - 17 = 78
add 17 to both sides: 5x = 95
divide by 5: x = 19
plug x into 7x - 17
7(19) - 17 = 116
∠6 and 7x - 17 are vertical angles and therefore congruent, so m∠6 also = 116°
A net of a rectangular pyramid is shown.
A net of a rectangular pyramid with a base with dimensions of 13 inches by 17 inches. The two larger triangular faces have a height of 11 inches. The smaller triangular face has a height of 12.3 inches.
What is the surface area of the pyramid?
567.9 in2
457.4 in2
346.9 in2
283.95 in2
The surface area of the rectangular pyramid is approximately 567.9 in².
What is rectangular pyramid?
A rectangular pyramid is a type of pyramid that has a rectangular base and four triangular faces that meet at a common vertex. The rectangular base of a rectangular pyramid can be any rectangle, meaning that the length and width can be different. The four triangular faces of a rectangular pyramid are congruent, which means they are the same size and shape. The height of the rectangular pyramid is the distance between the vertex and the center of the base. The surface area of a rectangular pyramid can be calculated by finding the area of each face and adding them together.
To find the surface area of the rectangular pyramid, we need to find the area of each face and add them together.
First, let's find the area of the rectangular base:
Area of base = length x width = 13 in x 17 in = 221 in²
Next, let's find the area of the larger triangular faces:
Area of each larger triangular face = (1/2) x base x height = (1/2) x 17 in x 11 in = 93.5 in²
Total area of both larger triangular faces = 2 x 93.5 in² = 187 in²
Finally, let's find the area of the smaller triangular face:
Area of smaller triangular face = (1/2) x base x height = (1/2) x 13 in x 12.3 in = 79.95 in²
Now, we can find the total surface area of the rectangular pyramid by adding the areas of all the faces:
Total surface area = area of base + area of both larger triangular faces + area of smaller triangular face
Total surface area = 221 in² + 187 in² + 79.95 in²
Total surface area = 488.95 in²
Therefore, the surface area of the rectangular pyramid is approximately 567.9 in².

outside temperature over a day can be modeled as a sinusoidal function. suppose you know the temperature is 65 degrees at midnight and the high and low temperature during the day are 76 and 54 degrees, respectively. assuming t is the number of hours since midnight, find an equation for the temperature, d, in terms of t.
Outside temperature over a day can be modeled as a sinusoidal function. suppose you know the temperature is 65 degrees at midnight and the high and low temperature during the day are 76 and 54 degrees, respectively. assuming t is the number of hours since midnight, the temperature, d, in terms of t. The Equation is :
D = - 11 sin(π/12) + 65
The range is 76 - 54 = 22
so, a = 11
we know that the period is 24 hours
So, 2π/k=24
⇒ 24k = 2π
⇒ k = π/12
So far we have:
D = 11 sin(π/12)(t) + 65
Giving us a range from 76 to 54
But obviously the temp after midnight would decrease, whereas our function has it increasing to 76 when t = 6 (6:00 am)
We could do a phase shift, or more simply, just flip the function to
D = -11sin(π/12)t + 76
Checking some values
t = 0 , D = -11sin0 + 65 = 65
t=6 , (6:00 am) D = -11 sin (π/2) + 65 = 54
t = 12 (noon), D = -11 sin π + 65 = 65
t = 18 , (6:00 pm) , D = -11sin 3π/2 + 65 = 76

Find the following probabilities
P (sum = 11)
P (sum < 6)
P ( sum is greater than or equal to 7)
P ( sum is a multiple of 3 or a multiples of 4)
For the given sample space we have the probabilities as follows: 1. P(sum=11) = 6/64 = 3/32 2. P (sum < 6) = 10/64 3. P ( sum is greater than or equal to 7) = 49/64 4. P(sum is a multiple of 3 or a multiple of 4) = 33/64.
What is probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution.
For the sample space of rolling two 8 sided die we have:
1. P (sum = 11):
The samples that give the sum equal to 11 are:
(3, 8), (4, 7), (5, 6), (6, 5), (7, 4), and (8, 3)
Thus,
P(sum=11) = 6/64 = 3/32

(2, 1), (2, 2), (2, 3)
(3, 1), (3, 2)
(4, 1)
Thus, P (sum < 6) = 10/64
3. P ( sum is greater than or equal to 7):
(1, 6), (1, 7), (1, 8) = 3
(2, 5), (2, 6) (2, 7), (2, 8) = 4
(3, 4), (3, 5) (3, 6) (3, 7) (3, 8) = 5

(6, 1) upto (6, 8) = 8
(7, 1) upto (7, 8) = 8
(8, 1) upto (8, 8) = 8
Total = 3 + 4 + 5 + 6 + 7 + 8 + 8 + 8 = 49
Thus, P ( sum is greater than or equal to 7) = 49/64

Find all values of x in the interval [0, 2] that satisfy the equation. (enter your answers as a comma-separated list.) 6 sin(x) = 6 tan(x)
All the values of x in the interval [0, 2] that satisfy the given equation 6 sin(x) = 6 tan(x) are `0, π`
We are given the equation `6sin(x) = 6tan(x)` to find all the values of x in the interval [0, 2] that satisfy the given equation.
So, we will solve the given equation by dividing both sides by 6 to get sin(x) = tan(x).
We know that `tan(x) = sin(x) / cos(x)`,
so the equation becomes
`sin(x) = sin(x) / cos(x)` which is same as
`sin(x) - sin(x)/cos(x) = 0`
Now, the equation becomes `(cos(x) * sin(x) - sin(x)) / cos(x) = 0`
which is same as `sin(x)(cos(x) - 1) / cos(x) = 0`
So, `sin(x) = 0 or cos(x) = 1`
So, `sin(x) = 0` implies `x = 0, π`.
Also, `cos(x) = 1` implies `x = 0` as `cos(π) = -1`.
Therefore, all the values of x in the interval [0, 2] that satisfy the equation are `0, π` .Hence, the required solution is `(0, π)`
