Which expression gives the distance between the points (5,1) and (9, -6)? Geometry worksheet

D.

Step-by-step explanation:

Distance Formula:

If you plug the coordinates in, you will see that in the y section of the formula, it should be an +, not a -, so D. is the correct answer.

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
