Find the velocity and acceleration vectors and the equation of the tangent line for the following curve, at the given value of t. r(t) = (cos(t))i + (sin(6t))j, at t = 0

is only a line? i think so

it has the same slope and a different y-intercept

hope this : )

step-by-step explanation:

32.50-7.50=25

225/25=11

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
