It's even better if you have a telescope or binoculars. Both allow you to see planets, the moon, and stars even closer. Telescop

es are more powerful than binoculars. With a telescope, you can see the moon close enough to see its features. Labeled images like this one can help you find different places on the moon or other objects in the night sky. Even without a telescope, you will still be able to find some of these place
What does this mean for you and your stargazing? Well, you may not make any major discoveries like Galileo did, but you can look up at the sky in your own backyard. You can see the moon and many of the same stars that early astronomers saw. You can even see planets. For example, this is an image of Venus, Mars, and the moon, as seen from Earth without a telescope or binoculars. It is amazing what you can find if you just look up!

What evidence does the author use to support the idea that a telescope is not needed to learn about Earth's moon?

A. Early astronomers saw many of the same starts without a telescope.
B. Looking up at the sky is enjoyable even if you don't have special tools.
C. You can see even more detail in the sky if you use a telescope.
D. You can see some of the features of the moon without a telescope.

Solve -5 + w divided by 3 = -1.<br><br> 12<br> -12 <br> 2 <br> -2
son4ous [18]

Hello!

<u><em>Answer:</em></u>

<u><em>w=12</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

First, you add by 5 from both sides of an equation.

-5+\frac{w}{3}+5=-1+5

Then, you simplify.

\frac{w}{3}=4

Next, you multiply by 3 from both sides of an equation.

\frac{3w}{3}=4*3

And finally, simplify and solve. You can also multiply by the numbers from left too right.

4*3=12

Final answer: → w=12

Hope this helps!

Thanks!

Have a great day!

What is the average rate of change of f(x) = -x2 + 3x + 6 over the interval –3
Rufina [12.5K]

Answer:

\frac{\Delta y}{\Delta x}  =\frac{f(x_2)-f(x_1)}{x_2-x_1} =\frac{6-(-12)}{3-(-3)} =\frac{18}{6}= 3

Step-by-step explanation:

To find the average rate of change of a function over a given interval, basically you need to find the slope. The mathematical definition of the slope is very similar to the one we use every day. In mathematics, the slope is the relationship between the vertical and horizontal changes between two points on a surface or a line. In this sense, the slope can be found using the following expression:

Average\hspace{3}rate\hspace{3}of\hspace{3}change=Slope=\frac{y_2-y_1}{x_2-x_1}  =\frac{f(x_2)-f(x_1)}{x_2-x_1}

So, the average rate of change of:

f(x)=-x^2+3x+6

Over the interval -3

Is:

f(x_2)=f(3)=-(3)^2+3(3)+6=-9+9+6=6\\\\f(x_1)=f(-3)=-(-3)^2+3(-3)+6=-9-9+6=-12

\frac{\Delta y}{\Delta x}  =\frac{f(x_2)-f(x_1)}{x_2-x_1} =\frac{6-(-12)}{3-(-3)} =\frac{18}{6}= 3

Therefore, the average rate of change of this function over that interval is 3.
