4 (r-10)^2+2=38
expand 4 [(r-10)(r-10)]+2=38
solve r-10×r-10
4 (r^2-20r+100)+2=38
-2 both sides
4 (r^2-20r+100)=36
÷4 both sides
r^2-20r+100=9
-9 both sides
r^2-20r+91=0
(r-7)(r-13)=0
r=7,13

An animal reserve has 40,000 elk. The population increases 11% a year. How long tell the population is equal to 80,000. If someo
Natasha2012 [34]

Answer:

7 years (This answer is to the nearest year)

Step-by-step explanation:

The way you could work this out is by trial and error. 11 % a year means that its population increases by 4400 annually. 40,000 X 1.11^1 gives you the amount it would be after one year (44000). I got the 1.11 because of the percentage (0.11) plus the amount you need to do percentage increase (1). Then all you do is keep on going up till you hit the number you need (80,000) after about 7 years the total would have hit 80,000 and would have actually went past it (83046)

What is the median for the numbers 3.60, 3.80, 5.44, 5.52, 5.72, 7.22?
Helen [10]
Okay so first of all we need to know the definition of our median first*
median: Given any group of numbers we put the numbers in order from least to greatest then find the number that's right in the middle. 
Here ill show you how we do it:)
<span>3.60, 3.80, 5.44, 5.52, 5.72, 7.22?
its already in order for us:)
but when we find the middle number it turns out that we have two middle numbers:/
simple:) all we do is take the two numbers add them together and divide by two
since our middle numbers are 5.44 and 5.52 we are going to use these:)
first add!
5.44 + 5.52 = 10.96 
now divide that by 2 
10.96 </span>÷ 2 = 5.48
so our median for this set of numbers is 
5.48!
hope this helps;)
