The distance ab rounded to the nearest tenth

Step-by-step explanation:

Givens

A = -2,1

B= 1,-1

Solution

AB = sqrt(  (-2 -   -1)^2 + (1 - -1)^2 )

AB = sqrt(  (-2 + 1)^2 + (1 + 1)^2 )

AB = sqrt(  (-1)^2 + 2^2)

AB = sqrt (1 + 4)

AB = sqrt(5)

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
