a programmer tells you that she has developed a new sorting algorithm with a worst-case run time of o(n^(3/2) ). what can you immediately infer about the way this algorithm works?
When a programmer informs you that she has created a new sorting algorithm with a worst-case run time of O(n^(3/2)), you can infer that the algorithm she created is a Polynomial-time algorithm.
What is the worst case?The given run time of O(n^(3/2)) means that the algorithm has a worst-case run time of n^(3/2). The time complexity of the given algorithm will grow in the order of n raised to the power [tex]\frac{3}{2}[/tex] When the size of the input data grows, the time it takes to solve the problem will grow in the order of n^(3/2) as well.
As a result, it can be concluded that the algorithm will be slower as the size of the input grows. Therefore, a polynomial time algorithm has been created that performs slowly when the input size increases. The best sorting algorithms can sort an array in[tex]O(n log n)[/tex]time, which is a more efficient sorting algorithm than the O(n^(3/2)) algorithm.

Bonding at service-entrance equipment is very important because service-entrance conductors do not have at their line side, other than the electric utility company's primary transformer fuses. (TRUE)
What's BondingA metal part that provides a permanent conductive path for electrical currents between various metals or non-metals is known as bonding. This includes everything from metal parts to conductive liquids and gases.The purpose of bonding at service-entrance equipment is to create a low-impedance path for ground-fault current.
When a fault current flows through the grounded conductors, the bonding jumper allows it to return to the source of supply instead of flowing through metal parts of the electrical distribution system. Ground fault current is directed to the service grounding electrode system as a result of this return path.
The connection of metal parts together to ensure the electrical continuity and low impedance path for a fault current is known as bonding. When it comes to service-entrance conductors, bonding is critical because they don't have anything on their line side other than the electric utility company's primary transformer fuses to prevent ground faults.

A LCD television consumes about 170 watts (depending on its size). A parent has the idea of coupling an electric generator to a stationary bicycle and requiring their children to power the TV whenever they want to watch it. In order to get an intuitive feel for the amount of effort it will take to power an LCD TV, determine the speed that an average person (70 kg) would need to bike up temple hill in Rexburg in order to produce the same amount of power required by the TV. Temple hill is at an approximate slope of 4.5 degrees. Assume no rolling friction loss, no friction loss in the bearings, no air drag, and that the bicycle has no mass. Give your answer in rounded to 3 significant figures. Number Units What is this speed in miles per hour? Give your answer in rounded to 3 significant figures. Number mph
An average person would need to bike up temple hill in Rexburg at a speed of approximately 15.740 mph to produce the same amount of power required by the TV.
To determine the speed an average person would need to bike up temple hill in Rexburg to produce the same amount of power required by the TV, we need to calculate the power output of the person and compare it to the power consumption of the TV.
First, let's convert the power consumption of the TV to units of watts:
170 watts
Next, let's calculate the power output of an average person biking up temple hill. We can use the formula:
Power = force x velocity
where force is the force required to bike up the hill, and velocity is the speed at which the person is biking.
To calculate the force required to bike up the hill, we can use the formula:
Force = mass x gravity x sin(theta)
where mass is the mass of the person, gravity is the acceleration due to gravity (9.8 m/s^2), and theta is the angle of the slope (4.5 degrees).
Plugging in the values, we get:
Force = 70 kg x 9.8 m/s^2 x sin(4.5 degrees) = 24.14 N
To calculate the power output, we can use the formula:
Power = Force x Velocity
We know that the power output needs to be equal to the power consumption of the TV, so:
24.14 N x Velocity = 170 watts
Solving for velocity, we get:
Velocity = 170 watts / 24.14 N = 7.036 m/s
To convert to miles per hour, we can multiply by 2.237:
Velocity = 7.036 m/s x 2.237 = 15.740 mph

The following code segment is intended to move the robot to the gray square. { repeat 4 times { move forward() rotate right() } rotate left() move forward() rotate right() } The answer is d. repeat 4 times.
When the given code is implemented, the robot will first move forward, then rotate right, move forward again, rotate right again, and repeat the above-mentioned step four times. After that, it will rotate left, move forward again, and finally rotate right. However, this will not lead the robot to the gray square as the requirement says. A solution to the above problem is to replace the blank with “repeat 4 times”. When we use the "repeat 4 times" command instead of the blank, the robot will perform the instructions inside the loop four times. So, the correct answer is d, i.e., repeat 4 times.

write an equation, in terms of the variables in the problem statement, for the amount of work required to compress the spring from the origin to x4.
The equation for the amount of work required to compress the spring from the origin to x4 is W = (1/2)kx², where k is the spring constant and x is the distance from the origin.
To write an equation for the amount of work required to compress the spring from the origin to x4, we can use the formula for work done by a spring:
W = (1/2)k(x2 − x1)²
Here, W represents the amount of work done by the spring, k represents the spring constant, and x2 and x1 represent the final and initial positions of the spring, respectively. In this problem, x1 is the origin, which is 0. Therefore, x2 is x4. Hence, the equation for the amount of work required to compress the spring from the origin to x4 is:
W = (1/2)k(x4)²
