1.) IF f(x)=3x-5 and g(x)=x^2, find (fxg)(3)

1 answer:

8 0

Please use * to denote mult. here, not "x." "x" is your variable and cannnot also be a symbol for mult.

f(x)g(x) = 3x^3 - 5x^2.

Now let x = 3:

(f*g)(3) = 3(3)^3 - 5(3)^2 = 81-45 = 36 (answer)

Distance = (rate)(time)
In this problem, note that both girls traveled the same distance.

Karens distance = r * 1.5 hrs we dont know her rate
Nancy distance = 50 * 1 hr we know she started 30 min later
but arrived at the same time

since the distances are equal
r*1.5 = 50 * 1 all you have to do is solve for r

1.5r = 50
r = 50/1.5
r = 33 1/3 miles per hour
