How does f(x) = 10x change over the interval from x = 5 to x = 6?
a) f(x) increases by 100%
b) f(x) increases by 500%
c) f(x) increases by 900%
d) f(x) increases by 1000%

C.

Step-by-step explanation:

The given function is

Substitute x=5 to get;

Substitute x=6 to get;

The percentage increment of over the interval from x=5 to x=6 is

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
