A function f(x) is said to have a jump discontinuity at x=a if: 1. limx→a− f(x) exists.

2. limx→a+ f(x) exists.

3. The left and right limits are not equal.

Let f(x)= {3x-3 if x <10

{4/x+4 if x ≥ 10

Show that f(x) has a jump discontinuity at x=10 by calculating the limits from the left and right at x=10.

lim f(x)=

x->10^-

lim f(x)=

x->10^+

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
