Initially a pool contains 250 gallons of water. a hose is placed in the pool, and the water is turned on. the hose adds 5.4 gallons of water per minute. write a linear model that represents the amount of water, v, in the pool as a function of time, t, in minutes.

The amount of water in pool after t minutes V = 250 + 5.4 t

Step-by-step explanation:

Amount of water in pool = 250 gallons.

The hose adds 5.4 gallons of water per minute.

Rate at which hose is adding water = 5.4 gallons per minute

We need to write a linear model that represents the amount of water, V, in the pool as a function of time, t, in minutes

We have

              V = 250 + 5.4 t

The amount of water in pool after t minutes V = 250 + 5.4 t                

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
