Acircular pond is modeled by the equation x^2 + y^2= 225. a bridge over the pond is modeled by a segment of the equation x – 7y = –75. what are the coordinates of the points where the bridge meets the edge of the pond?
a (9, 12) and (–12, 9)
b (9, 12) and (12, 9)
c (9, –12) and (–12, –9)
d (–9, 12) and (12, –9)

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

16.80 times .20= 3.36
