Answer:

Step-by-step explanation:
h= 1000 ft
dx/dt= 232 ft/sec
D= 1600 ft
First, we have to find a distance x ( shown in the figure)
applying pythagorus theorem
D^2= h^2+x^2................1
x^2= D^2-h^2
= 1600^2-1000^2
x^2= 1560000
x=1248.99 m
Now we can find out how fast the aircraft is receding from the trawler
( notice that the height is not changing)
so differentiating equation 1 w.r.t t we get

2DD'= 2hh'+2xx'

now putting values we get


Answer:
Its -1.9 for where point D is
Answer:
95 in.²
Step-by-step explanation:
Total surface area of the rectangular pyramid = 4(area of triangle) + area of rectangle
Area of triangle = ½*base*height
base = 5 in.
height = 7 in.
Area of triangle = ½*5*7 = 17.5 in.²
Area of rectangle = Length*width = 5*5 = 25 in.²
Plug in the values
Total surface area of the rectangular pyramid = 4(17.5) + 25
= 95 in.²
