Answer:
(-5, -8)
Step-by-step explanation:









First of all, you should know/notice that

You should also know how negative exponents work:

So, if you wanted

the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:

Your answer would be -3/4n+3/8 because 1/4•-3/1n would be -3/4n and then 1/4•3/2 would be 3/8 so your answer would then be -3/4n+3/8.
26 , 8-6=2 so you do 24+6
Answer:
Step-by-step explanation:
The average value theorem sets:
if f (x) is continuous in [a, b] and derivable in (a, b) there is a c Є (a, b) such that
, where
f(a)=f(π/2)=-4*sin(π/2) = -4*1= -4
f(b)=(3π/2)=-4*sin(3π/2) = -4*-1 = 4


⇒

c≅130
