What's the absolute value of-4/25

If f(n) = 6.07n, find: a. f(0.3) b. f(2.5) c. f(.0)

Scorpion4ik [409]

Simply plug in the numbers for n.
a. f(0.3) = 6.07(0.3)
f(0.3) = 1.821

b. f(2.5) = 6.07(2.5)
f(2.5) = 15.175

c. f(0) = 6.07(0)
f(0) = 0

Nostrana [21]

Week 1 : 1 customer tells 3 friends

Week 2: 3 new customers tell 9 friends

Week 3: 9 new customers tell 27 friends

If w represents number of weeks, then (C) represents the model appropriately. Let's see how:

Putting w = 1 , 2 and 3 in each of the options

(A) 3w: 3 for week 1, 6 for week 2, 9 for week 3 ⇒ INCORRECT

(B) w^3: 1 for week 1, 8 for week 2, 27 for week 3 ⇒ INCORRECT

(C) 3^w: 3 for week 1, 9 for week 2, 27 for week 3 ⇒ CORRECT

(D) 3w^3: 3 for week 1, 24 for week 2, 81 for week 3 ⇒ INCORRECT

Reika [66]

L is the closest to -12.6. It's obvious to see that every unit (1) on the number line is divided into five segments, so that each small segment represents 1/5=0.2. We know that -12.6 is between -12 and -13. -12.6 is 0.6 farther to the left than -12 (since -12.6 more negative), so we count 0.6/0.2=3 segments to the left of -12, corresponding to point L on the number line.
