Option-C is correct that is the algebraic expression of the function F = (x +y +z').(x +y' +z').(x' +y +z) from the circuit in the picture.
Given that,
We have to find what is the algebraic expression of the function F.
In the picture we can see the diagram by using the circuit we solve the function F.
We know that,
From the circuit for 3 - to - 8 decoder,
D₀ = \(\bar{x}\bar{y}\bar{z}\)
D₁ = \(\bar{x}\bar{y}{z}\)
D₂ = \(\bar{x}{y}\bar{z}\)
D₃ = \(\bar{x}{y}{z}\)
D₄ = \({x}\bar{y}\bar{z}\)
D₅ = \({x}\bar{y}{z}\)
D₆ = \({x}{y}\bar{z}\)
D₇ = xyz
We can see bubble after D₀ to D₇ in the circuit,
So, Let A = \(\bar{D_1}\) = \(\overline{ \bar{x}\bar{y}{z} }\) = x + y + \(\bar{z}\)
Now, Let B = \(\bar{D_3}\) = \(\overline{ \bar{x}{y}{z} }\) = x + \(\bar{y}\) + \(\bar{z}\)
Let C = \(\bar{D_4}\) = \(\overline{ {x}\bar{y}\bar{z} }\) = \(\bar{x}\) + y + z
Now, Output F = A.B.C
F = (x + y + \(\bar{z}\)).(x + \(\bar{y}\) + \(\bar{z}\)).(\(\bar{x}\) + y + z)
F = (x +y +z').(x +y' +z').(x' +y +z)
Therefore, The algebraic expression of the function F = (x +y +z').(x +y' +z').(x' +y +z).

Given that f ′ ( x ) = sqrt(5 x + 6) and g ( x ) = x2 − 2 , find
F ′ ( x ) if (x)=((x)
Answers
To find F'(x) when F(x) = √(f(g(x))), we can apply the chain rule of differentiation. The chain rule states that if we have a composite function F(g(x)), then the derivative of F with respect to x is given by F'(g(x)) * g'(x).
In this case, F(x) = √(f(g(x))), where f'(x) = √(5x + 6) and g(x) = x^2 - 2. We want to find F'(x).
First, we differentiate f(g(x)) with respect to x:
F'(x) = f'(g(x)) * g'(x)
Substituting the given values, we have:
F'(x) = √(5(g(x)) + 6) * (2x)
Since g(x) = x^2 - 2, we can substitute this expression into the equation:
F'(x) = √(5((x^2 - 2)) + 6) * (2x)
Simplifying further:
F'(x) = √(5x^2 - 10 + 6) * (2x)
F'(x) = √(5x^2 - 4) * (2x)
Thus, the derivative F'(x) of F(x) = √(f(g(x))) is √(5x^2 - 4) * (2x).

Answers
The domain is p ≠ -2 or in interval notation, (-∞, -2) U (-2, ∞).
How we find the domain?Is this function continuous for all values of pThe function given is \(y = 35/(p+2)^(^2^/^5^)\). This function is continuous for all values of p except when the denominator is zero. The denominator becomes zero when p = -2. So, no, this function is not continuous for all values of p.
Is this function continuous at p = 24Since the function is continuous for all values of p except p = -2, and 24 is not equal to -2, yes, this function is continuous at p = 24.
Is this function continuous for all p ≥ 0For p ≥ 0, the function is continuous, as the only discontinuity occurs at p = -2, which is not in the range p ≥ 0. So, yes, this function is continuous for all p ≥ 0.
The domain for this application is all real numbers except for the point of discontinuity, which is p = -2. Therefore, the domain is p ≠ -2 or in interval notation, (-∞, -2) U (-2, ∞).

Steve wants to start his own T-shirt business. His initial costs to get the business going are $1,500. It also costs on average $3 per shirt. Steve charges $10 for each shirt he sells. Which of the following systems is correct for this model to find the break-even point if "x" = the number of shirts sold and "y" = the number of dollars of expense or income?
Answers
Answer:
Below
Step-by-step explanation:
To find the break-even point, we need to determine the point at which the total revenue equals the total cost. Let's call the number of shirts sold "x".
The total cost includes the initial costs of $1,500 and the cost per shirt of $3x, so the total cost is:
y = 1500 + 3x
The total revenue is the price per shirt of $10 multiplied by the number of shirts sold, so the total revenue is:
y = 10x
To find the break-even point, we need to set the total cost equal to the total revenue and solve for x:
1500 + 3x = 10x
Simplifying this equation, we get:
1500 = 7x
Dividing both sides by 7, we get:
x = 214.29
Therefore, Steve needs to sell 215 shirts to break even.So the correct system to find the break-even point is:
y = 1500 + 3x (total cost)
y = 10x (total revenue)
A kangaroo is standing on a hill that is 4 feet off the ground. It starts to jump up with an initial velocity of 24 feet/second. Find the kangaroo max height.
Answers
The kangaroo maximum height is 8.5 feet
Finding the kangaroo max height.From the question, we have the following parameters that can be used in our computation:
Initial height = 4 ft
Initia; velocity = 24 ft/s
We start by writing the height function as
h(t) = -32t^2 + 24t + 4
Where
32 = acceleration of gravity
So, we differentiate and set to 0
-64t + 24 = 0
Solve for t
t = 24/64
So, we have
Max height = -32(24/64)^2 + 24(24/64) + 4
Evaluate
Max height = 8.5
Hence, the max height = 8.5

If f is continuous for all x, which of the following integrals necessarily have the same value?
Answers
Answer:
B
Step-by-step explanation:
Given the three integrals, we want to determine which integrals necessarily have the same value.
We can let the first integral be itself.
For the second integral, we can perform a u-substitution. Let u = x + a. Then:
\(\displaystyle du = dx\)
Changing our limits of integration:
\(u_1=(0)+a=a \text{ and } u_2 = (b+a)+a = b+2a\)
Thus, the second integral becomes:
\(\displaystyle \int_{0}^{b+a}f(x+a)\, dx = \int_a^{b+2a} f(u)\, du\)
For the third integral, we can also perform a u-substitution. Let u = x + c. Then:
\(\displaystyle du = dx\)
And changing our limits of integration:
\(\displaystyle u_1=(a-c)+c=a \text{ and } u_2=(b-c)+c=b\)
Thus, our third integral becomes:
\(\displaystyle \int_{a-c}^{b-c}f(x+c)\, dx = \int_{a}^{b} f(u)\, du\)
Since the only difference between f(x) and f(u) is the variable and both the first and third integral have the same limits of integration, our answer is B.

Answers
The number of times you can expect not to draw a point card in 30 turns is 20.
What is Probability?
Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
We have,
Total number of turns = 6 + 3 + 9 = 16
Number of times point card drawn = 6
Probability of finding the point card = 6/18 = 1/3
If the number of turns is 30,
Number of times point card is drawn = 1/3 × 30 = 10
Number of times point card is not drawn = 30 - 10 = 20
Hence there are 20 times that the drawn card is not point card.

Technology required. A regular hexagon is inscribed in a circle of radius 1 inch. What is the area of the shaded region? (Lesson 4-10)
Answers
The area of the shaded region in the given shapes is determined as 0.544 in².
What is the area of the shaded region?
The area of the shaded region is calculated by subtracting the area of the inscribed hexagon from the area of the circle.
Let's start by finding the side length of the regular hexagon inscribed in the circle.
The distance from the center of the circle to any vertex of the hexagon is equal to the radius of the circle, which is 1 inch.
In a regular hexagon, all sides are equal in length, so each side of the hexagon is also equal to 1 inch.
The area of the regular hexagon can be found using the formula:
Area of a regular hexagon = (3√3/2) x (side length)²
Substituting the side length of 1 inch, we get:
Area of regular hexagon = (3√3/2) x (1 inch)^2
= (3√3/2) square inches
= 2.598 in²
Now, to find the area of the circle, we can use the formula:
Area of a circle = π x (radius)²
Substituting the radius of 1 inch, we get:
Area of circle = π x (1 inch)²
= π square inches
= 3.142 in²
Area of the shaded region = area of circle - area of hexagon
= 3.142 in² - 2.598 in²
= 0.544 in²

Answers
Based on the information provided, the learning rate observed by the operations manager for a new production process is 96%.Given that unit #4 took 41.47 minutes to complete, we can estimate the time required to complete unit #5 using the learning curve formula:$$T_n = T_1 \times n^{-b}$$ where Tn is the time required to complete the nth unit, T1 is the time required to complete the first unit, n is the unit number, and b is the learning rate expressed as a decimal. To use this formula, we need to first find T1.
We can do this by using the time taken to complete unit #4. We know that unit #4 took 41.47 minutes to complete. Using the formula above, we can write:
$T_4 = T_1 \times 4^{-b}$$$$41.47
= T_1 \times 4^{-0.96}$$ Solving for T1,
we get:$$T_1 = \frac{41.47}{4^{-0.96}} \approx 13.559$$
Therefore, T1 ≈ 13.559 minutes. Using this value of T1 and the learning rate of 96%, we can find the time required to complete unit #5:$$T_5 = T_1 \times 5^{-0.96}$$$$T_5 = 13.559 \times 5^{-0.96} \approx 10.016$$Therefore, the estimated time required to complete unit #5 is approximately 10.016 minutes.

(c) a contestant takes 6 seconds to reach the ground from the top of the zip line. at what rate is the contestant moving down the line?
Answers
By using speed calculation and the Pythagorean theorem, it can be concluded that the contestant is moving down at a rate of 11.8 feet/second.
In speed calculation, speed is defined as the distance traveled in a certain unit of time. Speed can be calculated by dividing the distance by time:
Speed = distance / time
We will need the Pythagorean theorem to solve the problem as well. It says that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the two shorter sides:
c² = a² + b²
Now we take a look at the problem.
The height of the pole = 50 feet
Distance between pole and anchor = 50 feet
Time = 7 seconds
We want to know the speed of a contestant, that is the distance traveled in 6 seconds.
Let c be the distance traveled, a be the height of the pole and b be the distance between the pole and the anchor.
We will use the Phtagorast Theory to find c:
c² = a² + b²
= 50² + 50²
= 2500 + 2500
= 5000
c = √5000
= 70.7 feet
Rate or speed the contestant moving down the line:
Rate = distance / time
= 70.7 / 6
= 11.8 feet/second
Thus, the contestant is moving down at a rate of 11.8 feet/second.
