When you decrease 20 to 11,the decrease is 9
the percentage decrease is
(9/20)*100
=9*100/20
=9*5
=45%
Hello,
Here is your answer:
The proper answer to your question is "1/18".
Here is how:
8*6=48
9*6=54
-
5*9=45
6*9=54
48-45=3
Which is 3/54!
3/3=1
54/3=18
Which means your answer is 1/18!
If you need anymore help feel free to ask me!
Hope this helps!
From the given function modeling the height of the ball:
f(x)=-0.2x^2+1.4x+7
A] The maximum height of the ball will be given by:
At max height f'(x)=0
from f(x),
f'(x)=-0.4x+1.4
solving for x we get:
-0.4x=-1.4
x=3.5ft
thus the maximum height would be:
f(3.5)=-0.2(3.5)^2+1.4(3.5)+7
f(3.5)=9.45 ft
b]
How far from where the ball was thrown did this occur:
from (a), we see that at maximum height f'(x)=0
f'(x)=-0.4x+1.4
solving for x we get:
-0.4x=-1.4
x=3.5ft
This implies that it occurred 3.5 ft from where the ball was thrown.
c] How far does the ball travel horizontally?
f(x)=-0.2x^2+1.4x+7
evaluationg the expression when f(x)=0 we get:
0=-0.2x^2+1.4x+7
Using quadratic equation formula:
x=-3.37386 or x=10.3739
We leave out the negative and take the positive answer. Hence the answer 10.3739 ft horizontally.
