# The diameter of the planet jupiter is 143,000 kilometers. in scientific notation, this would be expressed as: 1.43x10^?

QUESTION POSTED AT 19/08/2019 - 05:55 PM

QUESTION POSTED AT 19/08/2019 - 05:55 PM

The correct answer is 143,000 = 1.43*10^5

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

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

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)]

I think the question should be solve for y or write quadratic eq.

27-9x+15y =0

divide all by 3

9-3x+5y = 0

solve for y

y = (3/5) x - (9/5)

27-9x+15y =0

divide all by 3

9-3x+5y = 0

solve for y

y = (3/5) x - (9/5)

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")
