Lelu [443]

Answer:

1. City A: 150 violent crimes per 100,000 residents.

   City B: 161 violent crimes per 100,000 residents.

2. City A

Step-by-step explanation:

City A:

Population = 123,000

Violent crimes = 185

Violent crimes per 100,000 people:

V_{100k} = \frac{185*100,000}{123,000} \\V_{100k} = 150

City B:

Population = 84,000

Violent crimes = 135

Violent crimes per 100,000 people:

V_{100k} = \frac{135*100,000}{84,000} \\V_{100k} = 161

1. City A: 150 violent crimes per 100,000 residents.

   City B: 161 violent crimes per 100,000 residents.

2. Even though it has a bigger number of crimes, City A has the lowest crime rate since its population is larger.

F(x) = -2x²-2x+10, find f(2)
beks73 [17]

Answer:

f(2) = -2

Step-by-step explanation:

Substitute 2 everywhere you see an x so f(2) = -2(2^{2}) - 2(2) + 10 so

f(2) = -2(4) - 4 + 10, so f(2) = -8-4+10, f(2) = -12+10, f(2) = -2
