Participants in the Iditarod must go 77 km, west from Rainy Pass to Rohn and then go 121 km, northwest from Rohn to Nikolai. Wha

iren2701 [21]

Answer:

8.6 km/hr

Explanation:

It looks like there's a lot of extra information here. If the question only asks about the trip from Rohn to Nikolai, then the only information that matters is that the distance between the two is 121 km & that Seavey did it in 14 hours. Don't let the extra numbers throw you off.

As for the math behind this - km/hr is a math equation in and of itself. Any ratio like that is a simple division problem. Just plug your numbers (121 km / 14 hr) into the formula (km / hr) to get your answer!

EDIT: for future questions where they don't label it as clearly... velocity = the distance divided by the time.

Which function is an extended function

likoan [24]

Answer:

D. The last option

Explanation:

You can't divide by 0, so find out when the given function is discontinuous.

$\frac{x^3+3x^2-x-3}{x^2-1} =\frac{x^3+3x^2-x-3}{(x+1)(x-1)}$

You can see that x is discontinuous at x=-1,1, so find a piecewise function that fill in those gaps.

Plug x=-1,1 into your function to find out what values you need to fill in. But of course it's discontinuous at those points, so plug in a number near x=1 and x=-1. I chose x=-1.1 and x=1.1

$f(-1.1)\frac{(-1.1)^3+3(-1.1)^2-(-1.1)-3}{(-1.1)^-1} = 1.9 \approx 2$

$f(1.1)\frac{(1.1)^3+3(1.1)^2-(1.1)-3}{(1.1)^-1} = 4.1 \approx 4$

so we need to fill in 2 at x=-1, and fill in 4 at x=1
