Y = n
y = x^2 + n
n > 0
since there are 2 equations equal to y, set them equal to each other and solve.
n = x^2 + n
Subtract n from both sides.
0 = x*2
Take the square root of both sides.
x = 0

Suppose a city with population 100,000 has been growing at a rate of 8% per year. If this rate continues, find the population

Natalija [7]

Answer:

$370,002\ people$

Step-by-step explanation:

In this problem we have a exponential equation of the form

$y=a(b^x)$

where

y is the population of the city

x is the number of years

a is the initial value or y-intercept

b is the base

r is the rate of growth

b=(1+r)

we have

$a=100,000\ people\\r=8\%=8/100=0.08\\b=1+0.08=1.08$

substitute

$y=100,000(1.08^x)$

For x=17 years

substitute the value of x in the exponential equation and solve for y

$y=100,000(1.08^17)$

$y=370,002\ people$

HELP PLEASE!!! I am doing my math and I need someone to help me with this problem. I am very confused and my family is gone on a

yanalaym [24]

Answer:

1) 250 meters= 0.25 km

2) 12 meters= 0.012km

3) 1 meter= 0.001 km

The constant of proportionality is 1000 meters in 1km (1000 meters)

I think there’s a mistake on the second part because 1 meter does not equal to 1000km. but I did part 1 for you!
