Answer: Distance of earth from star = 24.78\times10^{14}\text{ miles}

Step-by-step explanation:

Given: A certain star is 4.2 \times 10^2 light years from the Earth.

One light year is about 5.9 \times 10^{12} miles.

Distance of earth from star = 4.2\times10^2\times 5.9\times10^{12}

=4.2\times5.9\times10^2\times10^{12}\text{ miles}\\\\=24.78\times10^{2+12}\text{ miles}\\\\=24.78\times10^{14}\text{ miles}

Hence, Distance of earth from star = 24.78\times10^{14}\text{ miles}

Write an equation of the line passing through the given point and satisfying the given condition. Give the equation (a) in slope
kramer

Answer:

y =  -\frac{1}{2}x + 10

Step-by-step explanation:

To find the equation of a line that passes through the point (8,6) and perpendicular to the equation 2x - y = 4, we will follow the steps below:

first write the equation 2x - y = 4 in a standard form

we will find the slope of our equation using this equation

2x - y = 4

y = 2x -4

comparing the above with

y = mx  + c

m = 2

m_{1}m_{2} = -1  ( slope of perpendicular equations)

2m_{2} = -1

m_{2}  = -1/2

our slope m = -1/2

We can now go ahead and form our equation

x_{1} =8   y_{1} =6

y-y_{1} = m (x-x_{1})

y-6 = -\frac{1}{2}(x-8)

y-6 =  -\frac{1}{2}x + 4

y=  -\frac{1}{2}x+4+6

y =  -\frac{1}{2}x + 10

I have to study for a test. It's for data management. Does anyone have tips? (Grade 7)
Vinil7 [7]

Studying: Use resources.

If your studying for a test, use some resources, like quizizz, quizlet, flashcards, or the internet. If you do, ask your parents for help. Think it like its your big test, and your studying a lot. If you study and try, you'll pass the test on data management. If you need it, ask your teacher for tutoring or practice some data management questions. Studying will help you not to fail a test.

Now, we'll talk about before the test.

Before test: Rest, eat breakfast, and stay calm.

Step-by-step explanation: Going to bed before a test can prevent you from going to sleep. For example, GMAS (for me) is coming soon, and my teacher encourage us to rest, eat breakfast and stay calm. A recommended time for you to go to bed is 8:00-9:30.

Now, about breakfast.

Eating breakfast is also important because you can perform better, in fact, scientists say that if students eat breakfast before a test or exam, they will perform better! Whatever you do, don't skip breakfast. If you do, you won't perform good, and theirs a chance you could fail.

Now, staying calm is the big one.

If your freaking out, stay calm, say a prayer and get your work done! Staying calm is the big one because most students (I am one of them) get worried if they're gonna fail. Keep this in mind: <u>Try. Your. Best.</u> If you don't try, you won't achieve anything. And please don't cheat. If you cheat, you'll have to repeat the whole grade. Can't cheat in college; you'll get kicked out.

During test: DO. NOT. CHEAT.

CHEATING WILL GET YOU KICKED OUT OF COLLEGE AND YOU'LL AUTOMATICALLY FAIL!!! If your computer prevents you from going to other sites, that is good, but don't pull out ANY study guides or notes during your test, unless it's open-notes. If you don't know a questions, skip it and go to the next one. Then go back, it will come to mind later. If your done with your test early, check your answers. Look back and think, "Is this correct?"

Hope you do good on your test!
