The # of taxi accidents is approximated by y = -143.3x^2 + 1823.3x + 6820 and the # of injuries is approximated by y = -416.72x^

2 + 4416.7x+ 8500. Let x = 0 represents 1990, x = 1 represents 1991, and so on. According to the equation for the # of accidents, if the trend continued, how many taxi accidents occurred in 1999 and injuries in 1999?

To analyze the problem first is to arrange the equations according to their uses:
# of taxi accident y = -143.3X^2+1823.3x+6820
# of injuries y = -416.72X^2+4416.7x+8500
So the answer if X = 9 will be represented by 1999
# of taxi accident y = 11622.4
# of injuries y = 14495.98
I hope you understand the answer and feel free to ask for more.

kotykmax [81]

Answer:

76,800

Step-by-step explanation:

Given the following :

Length = 20 kilometers

Width = 12 kilometers

Population density = 320 people per sq km

Population =?

Recall:

Area of rectangle = Length × width

Therefore,

Area of Rectangleville = 20 km × 12 km = 240km^2

Population is related to population density and Area by the formula ;

Population density = population ÷ Area

Therefore,

Population = population density × Area

Population = 320 × 240 = 76,800

Therefore, the population of Rectangleville is 76,800 people

Homer wants to identify the center and radius of the circle defined by the equation...​
Goryan [66]

Answer:

Step 2, he didn't add the values he completed the square with to both sides.

Step-by-step explanation:

When you complete the square, you need to add the values to both sides, not just one.

So when Homer added 49 + 1 or 50 to the left side of the equation, he should've also added 50 to the right side of the equation.

Hence, the equation would now be :

(x-7)^2 + (y+1)^2 = 75
