Answer:
Step-by-step explanation:radius r = 4 m
height h = 13 m
slant height s = 13.6014705 m
volume V = 217.817091 m3
lateral surface area L = 170.921119 m2
base surface area B = 50.2654825 m2
total surface area A = 221.186602 m2
Answer:
Step-by-step explanation:
(15+13+12+12+20)/5
= 72/5 = 14.4
Answer:
2m – 3 = m + 5
correct answer
Step-by-step explanation:
Answer:
DL/dt = 17 mph
Step-by-step explanation:
The ships and the port shape a right triangle
Ship going west ( x-direction) is traveling at 15 mph
Ship going north (y-direction) is traveling at 10 mph
The distance L between ships is:
L² = x² + y²
Tacking derivatives on both sides of the equation with respect to time
we get
2*L*DL/dt = 2*x*Dx/dt + 2*y*Dy/dt (1)
In that equation we know:
Dx/dt = 15 mph
Dy/dt = 10 mph
At the moment ship traveling from the east is at 3 miles from the port
then x = 3 m and the other ship is at 4 miles north
then by Pythagoras theorem
L = √ 3² + 4² L = 5
By substitution in equation 1
2*5*DL/dt = 2*3*15 + 2*4*10
10* DL/dt = 90 + 80
DL/dt = 170 / 10
DL/dt = 17 mph
