Answer:

The box is 7.5 in long.

Step-by-step explanation:

Calculate the total surface area of the sides of this box (neglecting the ends).

If the base is 3" by 3" and the length of the box is 6", then the total surface area (without ends) is 4 times 3" by x, or  12x in².  80% of this "lateral surface area" is 0.80(12x in²), or 9.60x in° and this 9.60x in² represents the surface area covered b y the label.  That label surface area is 4(3 in by 6 in), or 72 in²

Equating 9.60x in² and 72 in² and solving for x yields  x = (72 in²) / (9.60 in²:

x = 7.5 in

The box is 7.5 in long.

Show that if u+v and u-v are orthognal, then the vectors u and v must have the same length.
pashok25 [27]

Answer with Step-by-step explanation:

We are given that

u+ v and u-v are orthogonal

We have to prove that u and v must have the same length.

When two vector a and b are orthogonal then

a\cdot b=0

By using the property

(u+v)\cdot (u-v)=0

We know that

(a+b)\cdot (a-b)=\mid a\mid^2-\mid b\mid^2

\mid u\mid ^2-\mid v\mid^2=0

\mid u\mid^2=\mid v\mid^2

Magnitude is always positive

When power of base on both sides are equal then base will be equal

Therefore,

\mid u\mid=\mid v\mid

Hence, the length of vectors u and v must have the same length.
