Its not one so 52 would be right
To find the absolute value remove abt negative sign in front of a number and to think of all numbers as a positive
Answer:
291.05ft²
Step-by-step explanation:
Volume of the aquarium = L³
L is the length of one side of the aquarium
444 = L³
L = cuberoot[444]
L= 7.63ft
Since the glass aquarium is opened at the top
Total surface Area = 5L²
Total surface Area = 5(7.63)²
Total surface Area = 291.05ft²
Hence the minimum exterior surface area of the aquarium is 291.05ft²
Answer:
Distance from the airport = 894.43 km
Step-by-step explanation:
Displacement and Velocity
The velocity of an object assumed as constant in time can be computed as

Where
is the displacement. Both the velocity and displacement are vectors. The displacement can be computed from the above relation as

The plane goes at 400 Km/h on a course of 120° for 2 hours. We can compute the components of the velocity as


The displacement of the plane in 2 hours is


Now the plane keeps the same speed but now its course is 210° for 1 hour. The components of the velocity are


The displacement in 1 hour is


The total displacement is the vector sum of both



The distance from the airport is the module of the displacement:
