A system consists of two different proportional relationships. What is the solution of the system?
Using concepts of proportional relationships, it is found that the solution of the system is (0,0).
What is a proportional relationship? A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:\(y = kx\)
In which k is the constant of proportionality.In this problem, the system consists of two different proportional relationships, that is:
\(y = k_1x\)
\(y = k_2x\)
\(k_1 \neq k_2\)
Hence, equaling both equations for y, we have that:
\(k_1x = k_2x\)
Simplifying by x:
\(k_1 = k_2\)
Which is never true, hence, the only solution is (0,0).

(Do not round your intermediate calculations. Round your final answer to 4 decimal places.) b. Each system component has a backup with a probability of .85 and a switch that is 100 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places. c. Each system component has a backup with a probability of .85 and a switch that is 90 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places.)
a. The probability that the system will operate as shown is approximately 0.6141.
b. Probability ≈ 0.6141The probability remains the same as in the previous case, which is approximately 0.6141.
c. The probability that the system will operate with each component having a backup with a probability of 0.85 and a switch that is 90% reliable is approximately 0.6485.
a. To find the probability that the system will operate as shown, we multiply the probabilities of each component. Since the system is shown to have three components with a probability of 0.85 each, we can calculate:
Probability = 0.85 × 0.85 × 0.85
Probability ≈ 0.6141
The probability that the system will operate as shown is approximately 0.6141.
b. In this case, each system component has a backup with a probability of 0.85 and a switch that is 100% reliable. Since the backup has a probability of 0.85, and the switch is 100% reliable (probability = 1), we can calculate the probability as:
Probability = 0.85 × 0.85 × 0.85
Probability ≈ 0.6141The probability remains the same as in the previous case, which is approximately 0.6141.
c. In this scenario, each system component has a backup with a probability of 0.85, but the switch is 90% reliable (probability = 0.90). We can calculate the probability as:
Probability = 0.85 × 0.90 × 0.85
Probability ≈ 0.6485
The probability that the system will operate with each component having a backup with a probability of 0.85 and a switch that is 90% reliable is approximately 0.6485.

At 11.00 a.m. a man started cycling from Newcastle to Hexham, 30 krn away. He
rode at a steady 10 km/h. He stopped for 30 minutes at 12.30 pm to have lunch
and then resumed his journey at the same steady speed. A car left Hexham for
Newcastle at 11.30 a.m. doing a steady speed of 50 km/h on the same road as the
cyclist. Draw a distance time graph to show the two journeys and use it to find the
approximate time and place at which the car and the cyclist passed each other.
The cyclist and the car will intersect at 11:50 AM.
To determine the approximate time and place at which the car and the cyclist passed each other the following calculation must be performed:
-The advance of each of the parts must be calculated, and the point where said movement coincides.
Cyclist = Point 0 at 11:00 A.M. --- Stops at 12:30 P.M. having circulated at 10 km / h, that is, it traveled about 15 km (12:30 - 11:00 = 1:30 (1.5)). After half an hour of rest, it continues on its way from 1:00 p.m., arriving at its destination at 2:30 p.m. If in 60 minutes it travels 10 km, in 6 minutes it travels 1 km, and per minute it travels 0.16 km. Car = Point 0 at 11:30 AM --- Speed of 50 km / h In half an hour it travels 25 km. In 6 minutes it travels 5 km, and per minute it travels 0.83 km. In total it takes 36 minutes to reach Newcastle at 12:06 P.M. 11:30 = Cyclist = 30 - 10 = 20 Car = 0 11:36 = Cyclist = 20 - 1 = 19 Car = 5 11:42 = Cyclist = 18 Car = 10 11:48 =Cyclist = 17 Car = 15 11:49 = Cyclist = 17 - (1/6) = 16.83 Car = 15 + (5/6) = 15.83 11:50 = Cyclist = 16.83 - (1/6) = 16.66 Car = 15.83 + 0.83 = 16.66Therefore, the cyclist and the car will intersect at 11:50 AM.

Pls help!!
Answer:
Domain {x : x > 1}
Range {y : y ∈ R}
Vertical asymptote x = 0
x-intercept (1, 0)
End behavior consistent
Graph attached down
Step-by-step explanation:
Let us study the equation:
∵ y = log(x)
→ It is a logarithmic function, so no negative values for x
∴ Its domain is {x : x > 1}
∴ Its range is {y : y ∈ R}, where R is the set of the real numbers
→ An asymptote is a line that a curve approaches, but never touches
∵ x can not be zero
∴ It has a vertical asymptote whose equation is x = 0
→ x-intercept means values of x at y = 0, y-intercept means
values of y at x = 0
∵ x can not be zero
∴ There is no y-intercept
∵ y can be zero
∴ The x-intercept is (1, 0)
→ The end behavior of the parent function is consistent.
As x approaches infinity, the y-values slowly get larger,
approaching infinity
∵ y = log(x) is a parent function
∴ The end behavior is consistent

Using integration by parts, rewrite the following integral as fudv = uv-fvdu [in (2x) e 4x² dx
To rewrite the integral ∫(2x)\(e^{4x^{2} }\)dx using integration by parts, we'll consider the function f(x) = (2x) and g'(x) = \(e^{4x^{2} }\).
Integration by parts states that ∫u dv = uv - ∫v du, where u and v are functions of x.
Let's assign:
u = (2x) => du = 2 dx
dv = \(e^{4x^{2} }\) dx => v = ∫\(e^{4x^{2} }\) dx
To evaluate the integral of v, we need to use a technique called the error function (erf). The integral cannot be expressed in terms of elementary functions. Hence, we'll express the integral as follows:
∫\(e^{4x^{2} }\) dx = √(π/4) × erf(2x)
Now, we can rewrite the integral using integration by parts:
∫(2x)\(e^{4x^{2} }\) dx = uv - ∫v du
= (2x) × (√(π/4) × erf(2x)) - ∫√(π/4) × erf(2x) × 2 dx
= (2x) × (√(π/4) × erf(2x)) - 2√(π/4) × ∫erf(2x) dx
The integral ∫erf(2x) dx can be further simplified using substitution. Let's assign z = 2x, which implies dz = 2 dx. Substituting these values, we get:
∫erf(2x) dx = ∫erf(z) (dz/2) = (1/2) ∫erf(z) dz
Therefore, the final expression becomes:
∫(2x)\(e^{4x^{2} }\) dx = (2x) × (√(π/4) × erf(2x)) - √(π/2) × ∫erf(z) dz
Please note that the integral involving the error function cannot be expressed in terms of elementary functions and requires numerical or tabulated methods for evaluation.

Answer:
d = 47°
Step-by-step explanation:
Image is attached
Sum of angles drawn along a straight line = 180°:
The angle drawn in pink : 180° - 112° = 68°
The angle drawn in green: 180° - 66° = 114°
The angle drawn in yellowish orange: 180° - 23° = 157°
The angle marked in purple: 180° - 102° = 78°
The figure drawn in the center is a 5-sided irregular pentagon
∴ Sum of interior angles in a 5-sided polygon = (n - 2) ×180°
= (5 - 2) × 180°
= 540°
The four angles calculated above will assist in calculating the fifth remaining angle of the pentagon (which is marked in light blue):
68° + 114° + 78° + 157° + angle in light blue = 540°
Angle in light blue = 540° - 68° - 114° - 78° - 157°
= 123°
Sum of angles drawn along a straight line = 180°:
Angle marked in dark blue = 180° - 123°
= 57°
Now focus on the angles present inside the triangle
Sum of interior angles of a triangle = 180°
= d + 76° + 57° = 180°
d has to be isolated and made the subject of the equation:

the explicit rule for an arithmetic sequence is f(n) 13 6(n 1). find the first four terms of the sequence.
The four terms of the sequence are 13, 19, 25, and 31.
To derive the first four terms of an arithmetic sequence with a given explicit rule, we can use the function given for the sequence and substitute specific values for n. The formula for the sequence is f(n) = 13 + 6(n - 1).
To find the first term of the sequence, we substitute n = 1 into the equation to get f(1) = 13 + 6(1 - 1) = 13. This means that the first term of the sequence is 13. To find the second term of the sequence, we substitute n = 2 into the equation to get f(2) = 13 + 6(2 - 1) = 19.
This means that the second term of the sequence is 19. To find the third term of the sequence, we substitute n = 3 into the equation to get f(3) = 13 + 6(3 - 1) = 25.
This means that the third term of the sequence is 25. To find the fourth term of the sequence, we substitute n = 4 into the equation to get f(4) = 13 + 6(4 - 1) = 31. This means that the fourth term of the sequence is 31. Therefore, the four terms of the sequence are 13, 19, 25, and 31.
