Find the area of the following ellipse (round to nearest tenth).

goblinko [34]

Answer:

$\huge\boxed{A=60\pi cm^2}$

Step-by-step explanation:

The formula of an area of a elipse:

$A=\pi ab$

We have:

$2a=10cm\to a=5cm\\\\2b=24cm\to b=12cm$

Substitute:

$A=\pi\dot5\cdot12=60\pi(cm^2)$

Light travels at 3.0 x 108 km/s. How far does light travel in 5 minutes?

masya89 [10]

3.0 x 10^8 km/s is how far light travels.
3.0 x 10^8 km/s x 60s is how far light travels in a minute
3.0 x 10^8 x 60 x 5 is how far light travels in 5 minutes, and you should get D as your answer.

The coordinates of one endpoint of a line segment are (4, −12). The length of the segment is 5 units. Determine four coordinate

Nina [5.8K]

Answer:

Four coordinate pairs that could serve as the other endpoint of the given line segment are given by: (9,-12), (-1,-12), (4,-7), (4,-17).

Step-by-step explanation:

One endpoint of (4,-12), length of 5 units.

Four possible pairs:

Add 5 to x, keep y: (4+5,-12) = (9,-12).

Subtract 5 from x, keep y: (4-5,-12) = (-1,-12).

Keep x, add 5 to y: (4,-12+5) = (4,-7)

Keep x, subtract 5 from y: (4,-12-5) = (4,-17)

Four coordinate pairs that could serve as the other endpoint of the given line segment are given by: (9,-12), (-1,-12), (4,-7), (4,-17).

How do you rotate 90 degrees counterclockwise about the origin?

andriy [413]

When rotating 90 degrees counterclockwise about the origin, the original coordinates are changed according to the rule (-y, x). Therefore, we take the original coordinates and switch them up accordingly to the rule listed above. When we do so, we get the coordinates Z'(4,0); J'(2,-5); L'(3,0). Hope this helps and have a phenomenal day!
