Answer:

The average rate will be -11000 dollars per year.

Step-by-step explanation:

The price of a house in 2005 = $250,000

The price of a house in 2010 = $195,000

at x₁ = 2005, f(x₁) = 250,000

at x₂ = 2010, f(x₂) = 195,000

Using the formula to determine the average rate of change for the

house each year.

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

= [195,000 - 250,000 ] / [2010-2005]

= -55000 / 5

= -11000

Therefore, the average rate will be -11000 dollars per year.

The attendance for a team's basketball game can be approximated with the polynomial -5x^2+80x+285, where x is the number of wins

Elan Coil [88]

Answer:

The attendance when the team won 4 games in the previous month is 525

Step-by-step explanation:

The attendance for a team's basketball game can be approximated with the polynomial : $-5x^2+80x+285$

x represents the number of wins the team had in the previous month.

Factor the polynomial :

$-5x^2+80x+285$

$-5(x^2-16x-57)$

$-5(x^2-19x+3x-57)$

$-5(x(x-19)+3(x-19))$

$-5(x+3)(x-19)$

Substitute the value of x = 4

The attendance when the team won 4 games in the previous month = -5(4+3)(4-19)=525

Hence The attendance when the team won 4 games in the previous month is 525
