Axis of symmetry of h(x) is x = 0
for f(x) its x = 2
and for g(x) its x = 3
so its
option 3
Answer:
1)
Independent variable: no. of passengers
Dependent variable: Average speed
2)
Inverse relationship
Fuel consumption increases as speed decreases
3)
Direct relationship
As the no. of passengers increase, fuel consumption also increases
4)
As the no. of passengers increase:
* speed decreases
* Fuel consumption increases
Answer is B.
5√3(5+2√6)=
25√3+10√18=
25√3+30√2
Note: I multiplied 10 by 3, because the prime factors of 18 are 3, 3 and 2 so I made a pair from the 3 and multipled and was left with 2.
Perimeter = (length+width) x 2
Let w units be the width of the rectangle.
Length of the rectangle = 2w
Perimeter:
(2w+w) x 2 = 60
(3w)2 = 60
6w = 60
w = 10
Area:
2(10) x 10
= 20 x 10
= 200 units
