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

QUESTION POSTED AT 23/09/2019 - 04:13 AM

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).

So, use "arctan x" instead.

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)]

QUESTION POSTED AT 23/09/2019 - 03:50 AM

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")

A squirrel ran 9 miles in 1 hour. Which expression can be used to determine its speed in miles per hour? 9 miles ÷ 1 hour 1 hour ÷ 9 miles 1 mile ÷ 9 hours 9 hours ÷ 1 mile

Answer:

Speed = 9 mile ÷ 1 hour .

Step-by-step explanation:

Given  : A squirrel ran 9 miles in 1 hour.

To find :  Which expression can be used to determine its speed in miles per hour.

Solution : We have given

Distance covered by squirrel : 9  miles.

Time covered = 1 hour .

Speed = \frac{Distance}{time}.

Speed =  \frac{9}{1} mile per hour.

Speed = 9 mile ÷ 1 hour .

Therefore, Speed = 9 mile ÷ 1 hour .
