PLEASE HELP Although a football field appears to be flat, some are actually shaped like a parabola so that rain runs off to both sides. The cross-section of a field can be modeled by y=−0.000234x(x−160), where x and y are measured in feet. What is the width of the field? What is the maximum height of the surface of the field? Round your answers to the nearest tenth, if necessary.

The width of the field is (blank)
feet.

The maximum height of the field is about (blank)
feet.

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

a - base

b - exponent
