Find the vertex and zeros of the following function f(x)=x^2-6x-7
elena-s [515]

Try this solution:

Step-by-step explanation:

1) for zeros of the function: x²-6x-7=0; ⇒ x₁=7; x₂= -1.

2) for the vertex of the function: x₀= -b/2a, where a;b;c - numbers from ax²+bx+c=0 (from x²-6x-7=0).

x₀=6/2=3;

y₀= (4ac-b²)/4a; ⇒ y₀= -16.

It means, the coordinates of the vertex are (3;-16).

maks197457 [2]

Answer:

Step-by-step explanation:

The formula for determining population density is expressed as

Population density = number of people/land area

The population of the U.S. Is about 309,975,000, covering a land area of 3,717,000 square miles. This means that the population density of the US is

309975000/3717000 = 83.39 people per square mile

The population of India is about 1,184,639,000, covering a land area of 1,269,000 square miles. This means that the population density of the India is

1184639000/1269000 = 933.52 people per square mile

Therefore, the population density of India is higher than the population density of the Us by

933.52 - 83.39 = 850.13 people per square mile
