Answer:
p=3
Step-by-step explanation:
Answer:
a) 10√2 is correct answer
The roller coaster starts at ground level.
Start: ground level, 0 ft altitude.
Climbs 110 ft: now it is at 0 ft + 110 ft = 110 ft altitude
Drops 65 ft: now it is at 110 ft - 65 ft = 45 ft altitude
Climbs 135 ft: now it is at 45 ft + 135 ft = 180 ft altitude
Since after the last step it is at 180 ft altitude, for the altitude to go back to 0, you must do 180 ft - 180 ft since 180 ft - 180 ft = 0 ft, ground level. The -180ft (the subtraction of 180 ft) part is a 180 ft drop. Therefore, the roller coaster needs to drop 180 ft to get back to ground level.
3^4 x 3^-5 x ^-2
= 3^(4 - 5 -2)
= 3^-3
1
= -------
3^3
The vertex is when x=-b/2a
in this case, b=-8, a=-1, so x=-(-8)/2(-1)=-4
when x=-4, y=-(-4)²-8(-4)+2=18
so the answer is B.
