if the ratio of the volume of two cubes is 1 : 8 , then find the ratio of the total surface area of the two cubes​
vivado [14]

Answer:

V = L^3      where v is volume and L the length of one side

A = 6 * L^2    total area of cube with side L

A = 6 * V^2/3      area of cube expressed in V

A2 / A1 = (V2 / V1)^2/3       6 cancels

A2 / A1 = 8^2/3 = 4      ratio of areas

2m=-6n-5 literal equation
Bingel [31]

Answer:

read below

Step-by-step explanation:

Alright, archtan /  

tan

−

1

(

x

)

is the inverse of tangent. Tan is  

sin

cos

. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.

Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.

Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.

Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.

the answer is m=-3n-5/2 or n=2m+5/6
