Part D When the membrane potential of a neuron begins returning to normal, resting levels, the cell membrane experiences summation repolarization depolarization Ohyperpolarization rest Submit Request Answer Part E Saltatory conduction allows for faster and more efficient conduction because action potentials are confined to which part of a neuron? Cell body Dendrites Axon terminal Axon hillock Nodes of Ranvier Submit Request Answer
The action potential "jumps" from node to node, allowing it to travel faster and with less energy loss than if it had to propagate along the entire length of the axon.
Part D: When the membrane potential of a neuron begins returning to normal, resting levels, the cell membrane experiences hyperpolarization.
During hyperpolarization, the membrane potential becomes more negative than the resting potential, making it more difficult to trigger an action potential.
Part E: Saltatory conduction allows for faster and more efficient conduction because action potentials are confined to the Nodes of Ranvier.
The Nodes of Ranvier are small gaps in the myelin sheath that covers the axon of some neurons. Because the myelin sheath insulates the axon, action potentials can only occur at the nodes, where the membrane is exposed. This means that the action potential "jumps" from node to node, allowing it to travel faster and with less energy loss than if it had to propagate along the entire length of the axon.

Jackie made a poster for the school advertising
the Science Olympiad. She included sample
statistics on the speed of the mousetrap cars
from the previous years. A. If one car raced 8 meters in 1. 5 seconds,
what was its speed?
b. How does this compare to the record time of
10 meters in 2. 32 seconds?
the speed of the car was 5.33 meters per second. Speed = 10 / 2.32 = 4.31 meters per second (rounded to two decimal places) .
a. To find the speed of the car, we use the formula
Speed = Distance / Time
If the car raced 8 meters in 1.5 seconds, we can substitute these values in the formula to get:
Speed = 8 / 1.5 = 5.33 meters per second (rounded to two decimal places)
Therefore, the speed of the car was 5.33 meters per second.
b. The record time of 10 meters in 2.32 seconds gives us a speed of:
Speed = 10 / 2.32 = 4.31 meters per second (rounded to two decimal places)
Comparing this to the speed of the car that raced 8 meters in 1.5 seconds, we see that the car that raced 8 meters was faster, with a speed of 5.33 meters per second compared to the record time of 4.31 meters per second. This suggests that the car that raced 8 meters was well-designed and well-built, and was able to travel a greater distance in a shorter amount of time.
It is important to note, however, that one data point is not enough to draw a firm conclusion about the superiority of one car over another. It is possible that the car that raced 8 meters had a lucky run, or that the car that set the record had a mechanical issue or was not driven to its full potential. To truly compare the performance of different cars, we would need to collect data from multiple trials and multiple cars, and analyze the data using statistical methods to determine which cars consistently perform better.

The set of ordered pairs (2,1), (3,3), (4,6), (2,3) is NOT a function because the input value of 2 corresponds to both the output values of 1 and 3.
For a set of ordered pairs to be a function, each input (x-value) must correspond to only one output (y-value). Therefore, if there exists an input (x-value) that corresponds to more than one output (y-value), then the set of ordered pairs is NOT a function.
Let's check each set of ordered pairs:
(5,3), (6,3), (7,3), (8,3): Each input (x-value) corresponds to the output (y-value) of 3. This set of ordered pairs is a function.(2,1), (3,3), (4,6), (2,3): The input value of 2 corresponds to both the output values of 1 and 3. Therefore, this set of ordered pairs is NOT a function.(1,6), (8,4), (3,8), (7,`): The output value for the fourth ordered pair is missing, so we cannot determine whether this set of ordered pairs is a function or not.(9,8), (7,6), (5,3), (2,1): Each input (x-value) corresponds to a unique output (y-value).

the yoko fund earns 11.2% during the year while the risk-free rate is 3.1%. the yoko fund has a beta of 1.20 and a standard deviation of 17.5%. the treynor ratio is closest to: a. 0.463 b. 0.640 c. 6.750 d. 9.333
For the Yoko Fund, the Treynor ratio is 6.0%, although none of the answer choices provided is a close approximation, we can choose option c. 6.750
The Treynor ratio measures the excess return earned by an investment per unit of systematic risk (i.e., beta). It is calculated as the difference between the return of the investment and the risk-free rate, divided by the investment's beta.
The formula for the Treynor ratio is:
Treynor Ratio = (Return of the Investment - Risk-Free Rate) / Beta
In this case, the return of the Yoko Fund is 11.2%, the risk-free rate is 3.1%, the beta is 1.20, and we are given the standard deviation of the Yoko Fund's returns, which is 17.5%.
Using the formula, we get:
Treynor Ratio = (11.2% - 3.1%) / 1.20
= 6.0%
Therefore, the Treynor ratio for the Yoko Fund is 6.0%.
None of the answer choices is exactly equal to 6.0%, but the closest one is (c) 6.750.

a charger has a power rating of 12 w. if you charge 6 cents per kilowatt hour, how much do you make in 1 day
The earnings made in 1 day when charging a device with a power rating of 12 W at a rate of 6 cents per kilowatt hour is 0.01728.
Given, Power rating of charger = 12 W. Charge per kilowatt hour = 6 cents = 0.06/kWh.To calculate the earnings in 1 day, we need to calculate the power consumed by the charger in 1 day first.
P = Power rating of charger = 12 Wt = Time = 1 day = 24 hours. Energy consumed = Power x Time. E = P x t= 12 W x 24 hours= 288 Wh = 0.288 kWh. Therefore, energy consumed by the charger in 1 day = 0.288 kWh.
Now, we can calculate the earnings in 1 day as follows: Charge per unit = 0.06/kWh. Earnings = Energy consumed x Charge per unit. Earnings = 0.288 kWh x 0.06/kWh= 0.01728.
Therefore, the earnings made in 1 day when charging a device with a power rating of 12 W at a rate of 6 cents per kilowatt hour is 0.01728.

The least common multiple (LCM) of two or more integers is the smallest positive integer that is a multiple of all of them. In other words, it is the smallest number that is divisible by each of the given numbers without leaving a remainder. [tex]3(5/8) + 2(3/8) = 6.[/tex]
What is the integer?To add the mixed numbers 5 3/8 and 3 2/8, we need to convert them to fractions with a common denominator. Since both have a denominator of 8, we can add the whole numbers to the fractions to get:
[tex]5 3/8 = 5 + 3/8 = 40/8 + 3/8 = 43/8[/tex]
[tex]3 2/8 = 3 + 2/8 = 24/8 + 2/8 = 26/8[/tex]
Now we can add these fractions:
[tex]5 3/8 + 3 2/8 = 43/8 + 26/8 = 69/8[/tex]
So the sum of [tex]5 3/8[/tex] and [tex]3 2/8[/tex] as a fraction is [tex]69/8[/tex] .
The LCM is often used when adding or subtracting fractions with different denominators, since we need to find a common denominator to perform the operation. To do this, we can find the LCM of the denominators and use it as the common denominator.
To write equivalent fractions with a common denominator, we need to find the least common multiple of the denominators, which in this case is 8.
For [tex]3(5/8)[/tex] :
[tex]3(8/8) + 5/8 = 24/8 + 5/8 = 29/8[/tex]
For [tex]2(3/8):[/tex]
[tex]2(8/8) + 3/8 = 16/8 + 3/8 = 19/8[/tex]
To add these fractions, we simply add their numerators:
[tex]3(5/8) + 2(3/8) = 29/8 + 19/8 = 48/8 = 6[/tex]
Therefore, [tex]3(5/8) + 2(3/8) = 6.[/tex]

Answer:
First, we need to calculate the daily interest rate on the credit card. We can do this by dividing the annual percentage rate (APR) by the number of days in a year:
Daily interest rate = APR / 365
Daily interest rate = 0.2445 / 365
Daily interest rate = 0.00067 or 0.067%
Next, we can calculate the interest that will accrue over the course of one month, which is approximately 30 days:
Interest = Balance * Daily interest rate * Number of days
Interest = $1,359 * 0.00067 * 30
Interest = $27.42
Adding the interest to the outstanding balance, we get:
Balance after one month = $1,359 + $27.42
Balance after one month = $1,386.42
Therefore, the balance on the credit card after one month will be approximately $1,386.42.
Find explicit formulas for sequences of the form a1, a2, a3, ... with the initial terms given
0, -1/2, 2/3, -3/4, 4/5, -5/6, 6/7
This formula generates the sequence 0, -1/2, 2/3, -3/4, 4/5, -5/6, 6/7, ...
Notice that the sequence alternates between positive and negative terms and that the denominators of each term increase by 1 while the numerators increase by 1 or -1. To find the explicit formula, we can write it in terms of its general form:
a1 = 0
a2 = -1/2
a3 = 2/3
a4 = -3/4
a5 = 4/5
a6 = -5/6
a7 = 6/7
We can see that the numerator of each term is equal to its index number, n, if n is even and equal to -n if n is odd. The denominator of each term is equal to n+1 for all terms.
Using this observation, we can write the explicit formula for the sequence as:
an = (-1)^(n+1) * n / (n+1)
where (-1)^(n+1) is equal to -1 if n is odd and 1 if n is even. This formula generates the sequence 0, -1/2, 2/3, -3/4, 4/5, -5/6, 6/7, ...

Determine weather the series is arithmetic or geometric,then find the indicated sum
The series, based on the general terms, can be found to be arithmetic. The indicated sum is - 544.
How to determine if a series is arithmetic or geometric ?To determine if the series is arithmetic or geometric, we must first find the common difference (arithmetic) or common ratio (geometric).
Term 1 (p=1): 19 - 2(1) = 17
Term 2 (p=2): 19 - 2(2) = 15
Term 3 (p=3): 19 - 2(3) = 13
There is a common difference of -2 so this is arithmetic.
The formula for the sum of an arithmetic series is:
Sum = (n x (a1 + an)) / 2
The series is: ∑ (p = 1 to 34) (19 - 2p)
To find the last term, we plug in p = 34:
an = 19 - 2(34)
= 19 - 68
= -49
The sum is therefore:
Sum = (34 x (17 + (-49))) / 2
Sum = -544
