10 in.
715 in.
1425 in.
1215 in.
Question 2:
Identify the equation of the circle B that passes through (4,−6) and has center (3,−2).

(x−3)2+(y+2)2=√17
(x − 3)2 + ( y + 2)2 = 17
(x + 3)2 + ( y − 2)2 = 17
(x+3)2+(y−2)2=√17

hey friend

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
