-- If a moving object speeds up, slows, down, or changes its direction, then that has to be because there's some force on it.
-- If there's no force on an object, then it keeps moving forever, at a constant speed in a straight line.
-- We can never see that happening on Earth, because around here, there's always some force on a moving object ... like gravity, friction, and air resistance. In order for it to actually happen, it pretty much has to be happening in outer space.
Examples:
-- The Earth keeps moving around the sun, and TV satellites keep moving around the Earth, without slowing down.
-- Even the International Space Station, orbiting about 270 miles above the earth's surface, is <u>almost</u> outside all of the atmosphere, but not quite. There's still a tiny bit of air out there, slowing it down and 'decaying' its orbit. About once a month, they have to give it a short burst of rocket fire, to boost it back up to the altitude where it's supposed to be.
Hmmmm.....what flag? Sorry, need specifics!
There are more than 500 species of sharks swimming in the world's ocean. ... They are found in just about every kind of ocean habitat, including the deep sea, open ocean, coral reefs, and under the Arctic ice.
Complement angles are angles which when added, the sum is equal to 90 degrees. In this case, we let angle one as x while angle 2 is represented by 17x. The equation then is equal to x + 17x = 90 ; 18x = 90. x from the equation is equal to 5. Hence teh angles are 5 degrees and 85 degrees
s(4) This means that t = 4, so you can plug in 4 for "t" in the equation
s(t) = 9t - 4
s(4) = 9(4) - 4
s(4) = 36 - 4
s(4) = 32
(4 , 32) This is the point on the graph. To graph it, each unit/square can be 4 [so go by 4's]
