Round the numbers to the nearest ten thousand:
63,000 km & 20,000 km
Then find the difference (subtract):
63,000 km - 20,000 km = 43,000 km
Don't forget to put the unit of measurement on there (km)
Hope this helps :)

8) through: (-3, -2), perp. to y = x – 1<br> A) y=-5x – 1 B) y=-4x – 5<br> C) y=-x – 5 D) y=-5x – 4

<u>Answer:</u>

The equation through (-3, -2) and perpendicular to y = x – 1 is y = -x -5 and option c is correct.

<u>Solution:</u>

Given, line equation is y = x – 1 ⇒ x – y – 1 = 0. And a point is (-3, -2)

We have to find the line equation which is perpendicular to above given line and passing through the given point.

Now, let us find the slope of the given line equation.

\text { Slope }=\frac{-x \text { coefficient }}{y \text { coefficient }}=\frac{-1}{-1}=1

We know that, <em>product of slopes of perpendicular lines is -1. </em>

So, 1 \times slope of perpendicular line =  -1

slope of perpendicular line = -1

Now let us write point slope form for our required line.

\mathrm{y}-\mathrm{y}_{1}=\mathrm{m}\left(\mathrm{x}-\mathrm{x}_{1}\right)

y – (-2) = -1(x – (-3))

y + 2 = -1(x + 3)

y + 2 = -x – 3

x + y + 2 + 3 = 0

x + y + 5 = 0

y = -x -5

Hence the equation through (-3, -2) and perpendicular to y = x – 1 is y = -x -5 and option c is correct.

Explain how to find the product 3^5 x 3^2 using rules for exponents.
AlekseyPX

Step-by-step explanation:

\because \:  {a}^{m}  \times  {a}^{n}  =  {a}^{m + n}  \\  \\  \therefore \:  {3}^{5}  \times  {3}^{2}  =  {3}^{5 + 3}  =  {3}^{8}  = 6,561 \\
