Can someone just answer this asap for

9 seconds

Step-by-step explanation:

The question asks for the solutions or the roots, if you wanted to solve algebraically there’s a number of ways, but I graphed it, the roots are the x intercepts, so 9,0 is our only positive answer, and therefore our only valid answer, so it takes 9 seconds for the hovercraft to land.

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
