JL has endpoints J(8,10) and L(20,5). Point K has coordinates (13,9). What is the length of JL?

Answers

The length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.

According to the question, we are required to determine the length of line JL.

However, the coordinates of the end points of line JL are given as;

Point J; (8,10)

Point L; (20,5).

The length of line JL is given by Pythagoras theorem as;

JL = √(20-8)² + (5-10)²

JL = √ 12² + (-5)²

JL = √ 144 + 25

JL = √169

JL = 13.

Therefore, the length of line JL which has endpoints J(8,10) and L(20,5) is; JL = 13.

X/2 -5=20 please give details

Answers

Answer: x=50

how?

[tex]\frac{x}{2}[/tex] - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:

[tex]\frac{x}{2}[/tex]=25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)

25 x 2= 50

therefor the x=50

prove that 5^(2n - 1) is divisible by 8

Answers

Your teacher must have made a typo somewhere. The expression 5^(2n-1) is not divisible by 8.

The expression 5^(2n-1) is composed of 2n-1 copies of "5" multiplied together. The key here is that 5 is the only unique prime factor of this number.

On the other hand, 8 = 2*2*2 = 2^3 showing that 2 is the only prime factor for this number. At this point, we can see that there's no way that 5^(2n-1) is divisible by 8. It all comes down to the clash of the primes 5 and 2 not matching up, and having nothing in common.

Let's consider a few concrete examples:

If n = 1, then 5^(2n-1) = 5^(2*1-1) = 5^1 = 5 which is not divisible by 8. The number 5/8 = 0.625 isn't an integer.If n = 2, then 5^(2n-1) = 5^(2*2-1) = 5^3 = 125 which is also not a multiple of 8. The number 125/8 = 15.625 isn't an integer.

I'll let you try other natural numbers for n, and you'll find that [tex]\frac{5^{2n-1}}{8}[/tex] isn't an integer.

In a river, a trout passed beneath a woman who was swimming at 1,800 centimeters per minute. The trout swam 8,000centimeters directly upstream at a constant velocity. It swam that distance in 0.8minutes. What was the trout's velocity?

Write your answer as a whole number.

centimeters per minute upstream

Answers

Answer:

It would approximately be 3.73 m/h

Step-by-step explanation:

0.8 mins is 48 seconds

I then divided 8000 by 48 seconds to see how many cm it traveled per second.

It traveled 166.666666667 cm per second

I then converted cm to feet

so it was 5.468066491699474 feet per second

I then converted feet to miles, so it was 0.0010356186537309611598 miles per second.

Then I multiplied it by 60 so it was 0.06213711922 miles per minute.

Finally I multiplied it by 60 again to make it 3.72822715343 miles per hour.

I rounded it to the nearest hundredth making it 3.73 m/h

When students get older, it gets even harder to wake up and it leads to many obstacles that can be avoided by starting school at later times. By starting schools later, students have been shown to improve academically, be more productive, not skip school, and maintain better health. A later start time should be incorporated into schools everywhere, especially high schools, for the benefit of teenage students. Grades are a very important aspect of education to many high school students, and grades are immensely dependent on adequate sleep. Later start times would allow for a greater quantity and quality of sleep. Poor sleep has a negative effect on a students academic performance. According to the Centers for Disease Control and Prevention (CDC), Adolescents who do not get enough sleep are more likely to perform poorly in school. Students who are not afforded the opportunity to get in the sufficient sleep they need will have a harder time focusing in school and doing well on exams. If schools were to push back the starting times in order to allow students to have a finer capacity of sleep, then the academic performance would improve, thus contributing to the common interest of all students. Many teenagers fall victim to car accidents and poor attendance records. Later start times would mean an improvement in attendance and safety as fewer students would sleep in or fall under the risk of driving to school in drowsy conditions. Enabling students to sleep more would cause more students to come to school on time and make them less likely to drive to school in a fatigued state. The Science Daily revealed that [...] later school start times were associated with a significant drop in vehicle accidents involving teen drivers. This could be tied to the fact that teens are in a more rushed mood to get to school on time from waking up late or that they are driving while tired, which can lead to many dangers. By starting schools at later times, the risks of teen car accidents would be reduced and the overall attendance would improve, thereby allowing for the betterment of students in all places Even with all the benefits of starting school at later times, there still remain those who challenge the idea. A common counterargument from the individuals in opposition to pushing back the schools starting times is that students should just sleep earlier. However, research has demonstrated that teenagers are biologically more likely to fall into a deeper sleep at later times. Science advocates say that young people's body clocks may shift as they reach their teenage years - meaning they want to get up later not because they are lazy but because they are biologically programmed to do. The biological clock of a teen does not correspond well with the schools starting times, and when a student is forced to wake up too early they are neglecting crucial parts of their sleep. In order to align better with teenagers internal clocks, schools should start at later times, which in return would result in the improvement of learning, concentration, and health. Students commit a large portion of their day towards school and it would be a more enjoyable process if schools were to start at a more seemly time. For the general welfare of students in public education, the school start times should be moved to later times. The benefits include better grades, fewer absences, safer roads, and increased attentiveness. There is additional potential to starting schools later, such as the reduction of risk in athletics, less depressive symptoms, and a decrease in the likelihood of participating in violence. The further possibilities can only be explored as more schools start pushing back their start times and in the idealistic future, schools will hopefully start to implement a delay to start times as it is better for everyone.
