Answer:
The rock climber climbs 378 feet in 30 minutes
Step-by-step explanation:
Given,
The rock climber averages 12 and 3/5 feet per minute.
That is, speed of climbing = ft per min,
Since Distance = speed × time,
If time = 30 minutes,
So, the distance, x, in feet covered by climber,
Hence, The rock climber climbs 378 feet in 30 minutes

Just plug in 10 for n
4 + (-1)^10
4 + 1 = 5
(7,0) and (1,0)
To find the x-intercepts, we set the equation equal to 0 and solve. So, we set x²-8x+7 equal to zero and solve. This can be factored as (x-7) and (x-1).
We have (x-7)(x-1)=0
x-7=0 x-1=0
x=7 x=1
X-intercepts: (7,0) and (1,0)
V=1/3bh324=1/3(9)* h 324=3hh=324/3h=108
height is 108cm
