A train traveled a distance of 255 kilometers. If the trip took 4 hours, what was the train's average speed in meters per second? Give your answer to the nearest whole unit.

255 km = 255,000 m
4 hrs = 14,400 sec
255,000 m/14,400 sec = 17.7083 --> 18 m/sec

average speed - 18 m/sec

Rewrite the expression as an algebraic expression in x. cos(tan−1 x)

It's hard to type and hard to read the "inverse tangent" function, as you've seen (above).

Then the problem becomes:  "differentiate cos (arctan x)."

You must apply first the rule for differentiating the cosine function, and next apply the rule for differentiating the arctan function:

(d/dx) cos (arctan x) = - sin (arctan x) * [1/(1+x^2)]

It is 0.09. this is because you do 3 multiply by 0.6. then you do 1.8divided by 20 because you want per one minute so that becomes 0.09 and that is your answer. Hope this helps I am really close to ranking up so if you can award me the most brainliest that would be great!! thanks and your welcome

4 PART Your weight on different planets is affected by gravity. An object that weighs 150 pounds on Earth weighs only 56.55 pounds on Mars. The same object weighs only 24.9 pounds on the Moon. A)What percent of an object's Earth weight is its weight on Mars and on the Moon? B)Suppose x represents an object's weight on Earth. Write two expressions: one that you can use to find the object's weight on Mars and another that you can use to write the ojbect's weight on the Moon. C)The space suite Neil Armstrong wore when he stepped on the Moon for the first time weighed about 180 pounds on Earth. How much did it weigh on the Moon? D)What if? If you could travel to Jupiter, your weight would be 236.4% of your Earth weight. How much would Neil Armstrong's space suit weigh on Jupiter? **not sure if my weight is needed for D, but I weigh 100 pounds.

Mars 100 * 56.55/150 = 37.7%
Moon 100 * 24.9/150 = 16.6% (about 1/6, remember that)

Mars .377 x
Moon .166 x

.166 * 180 = 29.9 pounds (note 180/6 =30)

180 * 2.364

Please convert this to a factored expression aka distributive property. 2r^2+r ^ means to the power

So, what you need to do here is factor one thing out--pick something that both terms have in common. in this case, the thing in common is the variable r.

factor out an r. your result is:

r(2r + 1)

the 1 comes from the "implied" or "understood" default coefficient that comes before every variable. the coefficient is 1 if a variable is standing alone (like if a problem just says "x")
