Answer:
y = 4x + 2
Step-by-step explanation:
y = mx + b
m is the slope
b is the y-intercept
Ya gotta use the Pythagorean theorem :)
a² + b² = c² (reminder: c is the hypotenuse)
4² + 8² = c²
16 + 64 = 80
√80 = 8.94
H = 8.94
10 I think..I might be wrong
Answer: 2,215,000
Step-by-step explanation:
Given: The quadratic function
models the population of a city where x represents the number of years since 2005.
To Find: population of the city in 2010
We need to put x= 2010-2005 = 5

Hence, the estimated population of the city in 201 = 2215 thousands or 2,215,000 .
