Sadie wants to sell her fan-fiction on the online platform Fanalot. Instead of selling a subscription plan to all of the stories she has written, she decides to sell readers access to each story individually. Her online research suggests that if she charges x dollars per story, she will sell – 5x+100 stories per month. Fanalot will charge Sadie 20% of the amount she charges per story. So, Sadie will earn 80% of the amount she charges per story, or 0.8x dollars, in profit. Which equation can Sadie use to estimate the price she can charge per story to earn $300 in profit each month?

The symmetrical load below is connected to a three-phase network. A line current of 25A has been measured. The load resistors have a value of 18 Ω.
What is the line voltage of the three-phase network?
Answer:
The line voltage of the three phase network is 346.41 V
Explanation:
Star Connected Load
Resistance, R₁ = R₂ = R₃ = 18 Ω
For a star connected load, the line current = the phase current, that is we have
\(I_L = 25 \, A = I_{Ph}\)
Whereby the the voltage across each resistance = \(V_R\) is given by the relation;
\(V_R\) = \(I_{Ph}\) × R
Hence;
\(V_{Ph}\) = \(V_R\) = \(I_{Ph}\) × R = 25 × 8 = 200 V
Therefore we have;
The line voltage, \(V_{L}\) = √3 × \(V_{Ph}\) = √3 × 200 = 346.41 V.
Hence, the line voltage of the three phase network = 346.41 V.

Perchuty (P. z fan ce the Treffe resistivalyThe law of resistivity.
We can see here that the law of resistivity, also known as Ohm's law, states that the electrical resistance of a conductor is directly proportional to its resistivity and length, and inversely proportional to its cross-sectional area.
How is law of resistivity represented?The Law of resistivity can be mathematically represented as:
R = ρ × (L / A)
Where:
R is the electrical resistance of the conductor,
ρ (rho) is the resistivity of the material,
L is the length of the conductor, and
A is the cross-sectional area of the conductor.
The resistivity (ρ) is a characteristic property of a material that quantifies its ability to resist the flow of electric current. It depends on the nature of the material, its temperature, and sometimes its purity. Resistivity is measured in ohm-meters (Ω·m).

A ship has a speed in still water of 10 ms¹ and is pointed in the direction N 30°E, but there is a current of speed 2 ms-¹ flowing towards the direction SE. By applying the Cosine or Sine Rule, find the resultant velocity of the ship, in terms of its speed and a bearing. Give your answers correct to one decimal place.
Answer:
Hope this helped ^^
Explanation:
To find the resultant velocity of the ship, we can use vector addition by considering the ship's velocity in still water and the velocity of the current separately.
Let's denote the ship's velocity in still water as Vship = 10 m/s, and the velocity of the current as Vcurrent = 2 m/s.
To find the resultant velocity, we can break down the ship's velocity and the current's velocity into their horizontal (East/West) and vertical (North/South) components.
The horizontal component of the ship's velocity (Vship_h) can be calculated using the cosine rule:
Vship_h = Vship * cos(30°)
Vship_h = 10 * cos(30°) = 10 * (√3 / 2) ≈ 8.7 m/s
The vertical component of the ship's velocity (Vship_v) can be calculated using the sine rule:
Vship_v = Vship * sin(30°)
Vship_v = 10 * sin(30°) = 10 * (1 / 2) = 5 m/s
Now, since the current is flowing towards the direction SE (southeast), which is 45° from the East direction, we can break down the current's velocity into its horizontal and vertical components.
The horizontal component of the current's velocity (Vcurrent_h) can be calculated using the cosine rule:
Vcurrent_h = Vcurrent * cos(45°)
Vcurrent_h = 2 * cos(45°) = 2 * (√2 / 2) = √2 m/s
The vertical component of the current's velocity (Vcurrent_v) can be calculated using the sine rule:
Vcurrent_v = Vcurrent * sin(45°)
Vcurrent_v = 2 * sin(45°) = 2 * (√2 / 2) = √2 m/s
Now, we can find the resultant horizontal velocity (Vresultant_h) by adding the horizontal components of the ship's velocity and the current's velocity:
Vresultant_h = Vship_h + Vcurrent_h
Vresultant_h = 8.7 + √2 ≈ 10.1 m/s
Similarly, we can find the resultant vertical velocity (Vresultant_v) by adding the vertical components of the ship's velocity and the current's velocity:
Vresultant_v = Vship_v + Vcurrent_v
Vresultant_v = 5 + √2 ≈ 6.4 m/s
Finally, we can calculate the magnitude of the resultant velocity (Vresultant) using the Pythagorean theorem:
Vresultant = √(Vresultant_h² + Vresultant_v²)
Vresultant = √(10.1² + 6.4²) ≈ 11.9 m/s
The bearing of the resultant velocity can be calculated using the inverse tangent (tan⁻¹) of the vertical component divided by the horizontal component:
Bearing = tan⁻¹(Vresultant_v / Vresultant_h)
Bearing = tan⁻¹(6.4 / 10.1) ≈ 33.7°
Therefore, the resultant velocity of the ship, in terms of its speed and bearing, is approximately 11.9 m/s at a bearing of 33.7°.

why a biomedical engineer would need to dilute any solutions?
Biomedical engineers may need to dilute solutions for several reasons. One common reason is to adjust the concentration of a particular substance to a desired level for experimental or clinical purposes.
Dilution allows for precise control over the concentration of a solution, enabling researchers or healthcare professionals to study the effects of different concentrations of substances on biological systems.
In biomedical engineering, dilution is often employed when working with drugs or therapeutic agents. By diluting a concentrated drug solution, engineers can create different dosages suitable for specific applications. This is crucial for ensuring patient safety and achieving desired therapeutic outcomes.
Additionally, dilution is necessary for calibration and quality control purposes in biomedical engineering. Diluting stock solutions of known concentrations can generate a range of standard solutions used to calibrate instruments, verify measurement techniques, or assess the accuracy of analytical methods.
Dilution plays a critical role in ensuring accurate and reliable data collection, analysis, and experimentation within the field of biomedical engineering.
In summary, dilution is an essential technique for biomedical engineers as it allows them to control the concentration of substances, customize drug dosages, and maintain accuracy in calibration and quality control processes, all of which are vital for research, development, and healthcare applications.

I'll give you the formula to calculate the net resistance of multiple resistors I'm in parallel.
1/R = 1/R1 + 1/R2 +1/R3 +……+1/Rn.
Take the reciprocal of each resistor value and add them up. The reciprocal value of a resistor is called its admittance. Add them up to get the total admittance. Notice that this value is 1/R. So take the reciprocal by dividing 1 by the total admittance value. Then you have the net resistance for all the parallel resistors.
Now you know the total resistance of the parallel values, if there are any other resistors in series with this, add them on to get the total resistance in the circuit.
Now use Ohm's law to find the current.
I =V/R

The distance between the Sun and the Earth is 150000000km (approximately) and the Sun subtends an angle of 32' with eye of man of the Earth, find the diameter of the Sun.
Answer:
the diameter of the Sun is approximately 1.392 million kilometers.
Explanation:
To find the diameter of the Sun, we can use the formula:
diameter = 2 x distance x tan(angle/2)
where distance is the distance between the Sun and the Earth, angle is the subtended angle of the Sun, and tan is the tangent function.
Substituting the values given, we get:
diameter = 2 x 150000000 km x tan(32'/2)
diameter ≈ 1.392 x 10^6 km
Therefore, the diameter of the Sun is approximately 1.392 million kilometers.

How do i code a hobby gearshift motor to speed 50 using only an arduino uno r3?
To code a hobby gearshift motor to run at a speed of 50 using an Arduino Uno R3, you can use pulse-width modulation (PWM) to control the motor speed.
General outline of the steps involved are:
1)Connect the hobby gearshift motor to the Arduino Uno. Ensure that you have the necessary motor driver or H-bridge circuit to interface the motor with the Arduino.
2)Set up the Arduino Uno by installing the Arduino IDE and connecting it to your computer.
3)Open the Arduino IDE and create a new sketch. Define the necessary pin for controlling the motor speed using PWM.
For example, you can use Pin 9 for this purpose:
const int motorSpeedPin = 9;
4)In the setup() function, configure the motor speed pin as an output:
void setup()
{
pinMode(motorSpeedPin, OUTPUT);
}
5)In the loop() function, use the analogWrite() function to set the desired speed for the motor.
Since the analogWrite() function uses PWM, the speed can be adjusted by varying the duty cycle from 0 to 255.
A duty cycle of 255 corresponds to the maximum speed. To achieve a speed of 50, you can use a duty cycle of approximately 128:
void loop()
{
analogWrite(motorSpeedPin, 128);
}
6)Upload the code to the Arduino Uno and observe the motor running at the desired speed.
