Outside of the United States, the common paper size is called A4 and measures 21 by 29.7 centimeters. Let be the volume in cubic centimeters of a box made from A4 paper by cutting out squares of side length in centimeters from each corner and then folding up the sides. What is a reasonable domain for in this context? Explain or show your reasoning.

answer:

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

n=1.75+1.75

step-by-step explanation:

3.5/2=1.75
