The mean distance of the Moon from Earth is 2.39x10^5 miles. Assuming that the orbit of the Moon around Earth is circular and th
olya-2409 [2.1K]

Answer:

2291,94 mph

Step-by-step explanation:

To solve this we need to consider the distance 2.39x10^5 miles as the distance between the center of the earth and the center of the moon, if not we would need to know the radius of the earth and the moon.

If the distance is 2.39x10^5 miles, the orbit is = 2.Pi.(2.39x10^5) miles=1501681.288miles

It takes 27.3 days, that are, 27.3*24= 655.2hours

1501681.288miles/655.2hours= 2291.94 mph

The vertices of a triangle are labeled clockwise A(–5, 3), B(6, 1), and C(–2, –3). How could you show that the figure is a right
mafiozo [28]

Explanation:

When the points are plotted on a graph, it is easy to see that the slope of AC is -2 and the slope of BC is 1/2. These slope values have a product of -1, so the corresponding line segments are perpendicular to each other.

___

If you have studied vectors, you can find the dot product of AC with BC:

  AC = (-5, 3) -(-2, -3) = (-3, 6)

  BC = (6, 1) -(-2, -3) = (8, 4)

The dot product is ...

  (-3, 6)·(8, 4) = (-3)(8) + (6)(4) = -24+24 = 0

When the dot product of vectors is zero, they are perpendicular.

Use the Distributive Property to write each expression as an equivalent algebraic expression.
Romashka [77]

Answer:

9x - 45

Step-by-step explanation:

To simplify this expression, we need to use Distributive Property to get rid of the parentheses. So, we multiply the -9 by everything inside the parentheses.

-9(-x + 5)

-9 · -x = 9x

-9 · 5 = -45

Now we add our products together.

9x + -45

Since there is a '+' sign and a '-' sign next to each other, we can simplify it to just a '-'.

9x - 45

Hope this helped! Let me know if you have any other questions! :)
