4. A laser beam travels along a straight path for a certain distance, and then bounces n times off tilted mirrors before striking a target. The laser beam travels v2 additional

centimeters each time it bounces off a mirror. When there are 5 bounces, the laser

beam travels 13v2 cm.

a. Let d (n) denote the distance the laser travels in cm as a function of the number

of bounces off a mirror, n. What does d(5) represent? What is the value of d(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
