Answer:
Solution given:
y=-1/2 x²
for
f(x)=-1/2 x².
differentiating each term with respect to x
f'(x)=-x
when
x=-4
f'(-4)=4>0 increasing
when
x=-2
f'(-2)=2 >0 increasing
when x=0
f'(0)=0 stationary point.
other points are decreasing
so
largest interval of increasing is
A.X<-2
Answer:
29%
Step-by-step explanation:
213/300 x 100 = 71%
100 - 71 = 29%
6 because if one number is divisible by another number's factors, then the first number is divisible by the second number. for example, take the numbers 18 and 6. the factors of 6 are 2 and 3. 18 is divisible by both 2 and 3, therefore it has to be divisible by 6.
It take 23 mins for the drive
He needs to reach the airport by a quarter before 6
a quarter before 6 = 5.45
So he needs to leave 23 mins before 5.45
23 mins before 5.45 = 5.22
Answer:
t=-1
Step-by-step explanation:
9-t=-2t+8 add t to both sides and subtract 8 from both sides
1=-t
1/-1=-t/-1
-1=t
