A) Now look, in the year 2000, the population is 118,000
In the year 2006 is 138,000
To find the percent change |Original Amt - New Amt| -------------------------------- x100
Original Amt
So for this question you would do 118,00 - 138,000 (ignore the negativesss)
and you get -20,000 (ignore the negatives) and then you get 20,000
Now, you have to do 20,000 divided by 118,000 x 100
20,000 divided by 118,000 and you get 0.169491525
Now you have to multiply 0.169491525 by 100
0.169491525 x 100 = 16.9491525
Round this and you get a 16.9% change.
b) To predict the population in 2012 you will have to do 138,000 + 16.9%
To calculate this you have to do this:
138,000 x 0.169 = 23322
Now add 23,322, to 138,000 and you get 161,322.
A) 16.9%
B) 161,322
hope this helped :)
Answer:
h(u)=-7/6u
Step-by-step explanation:
To write a formula for v in terms of u, you need to first isolate v.
4u+8v=-3u+2v
Add 3u to both sides:
7u+8v=2v
Subtract 8v from both sides:
7u=-6v
Divide both sides by -6:
v=-7/6u
Hope this helps!
His new time compared with the old time was increased by factor of 2
<h3>Further explanation</h3>
Acceleration is rate of change of velocity.
<em>a = acceleration (m / s²)v = final velocity (m / s)</em>
<em>u = initial velocity (m / s)</em>
<em>t = time taken (s)</em>
<em>d = distance (m)</em>
Let us now tackle the problem!
This problem is about Kinematics.
In this problem we assume that the unicorn is moving at a constant speed so that the acceleration is zero.
<u>Given:</u>
first distance = d₁ = 50 miles
second distance = d₂ = 300 miles
v₂ = 3 v₁
<u>Unknown:</u>
t₂ : t₁ = ?
<u>Solution:</u>
To find his new time , we will use the following formula.
