It will take approximately 17 1/2 years for the city to reach a population of 1,000,000.

Step by Step Explanation:

7% of 450,000 is 31,500

450,000 to 1,000,000 means you need another 550,000 people in your population.

So take 550,000 divided by 31,500, which equals 17.46, which then rounds up to 17.5 years.

17.5 x 31,500= 551,250

That is how long it will take to reach 1,000,000 population count when the population only increases 7% each year.

At the shorter waterfall, water falls uninterrupted for 1552 feet before entering the river below. The height h above the river
qwelly [4]

Answer:

<h3>9.9s</h3>

Step-by-step explanation:

First note that the river is on the ground level. The height of the river at the ground level is 0

Given the the height h above the river in feet of water going over the edge of the waterfall is modeled by h(t)=-16t^2+1552

When h = 0

0 = -16t^2+1552

16t^2 = 1552

t² = 1552/16

t² = 97

t = √97

<em>t = 9.9secs</em>

<em>Hence the time it takes is 9.9secs to the nearest tenth</em>

If y=x+2 we’re changed to y=x-1 how would the graph of a new function compare with the first one
butalik [34]

The y-intercept is being changed. In the equations given we are using the formula (y=mx +b), b means the y intercept. In this we are changing the y intercept from 2 to -1. There is nothing else being changed.

What is the sum of the first 11 terms of the arithmetic series in which a1= -12 and d=5?
SVEN [57.7K]
Hello :  
the terme general is : an = a1 +(n-1)d
 a11 = a1+(11-1)×5
a11 = -12+50
a11 = 38
<span>the sum of the first 11 terms is : S11 = (11/2)(a1+a11)
</span>S11 = (11/2)(-12+38)
S11 = 143
