Answer is 9
A(x)=f(b)-f(a)/b-a
where a=-10 b=10
f(x)= x^2+9x+18
f(a)=(-10)^2-90+18=28
f(b)=208
A(x)=208-28/10+10
A(x)=180/20=9
Answer:
a.35.25
b. 42.56
c.23.06
Step-by-step explantion
Just subsitute 30, 15, and 5 for x each time for each question
ex:
y=-0.0975(5)^(2)+3.9(5)+6
Answer:
There are 2 points for a field goal, and 1 point for a free throw. ... It is also given that, you have scored at least 3 points in every ...
%change=100(final-initial)/initial
You can plug in your values...if you meant initial=12 and final=36...
%change=100(36-12)/12=200%
Since it is positive, that is a 200% increase.
