Tanya [424]

Answer:

The fence will still be five feet high because the lengthening of the tree occurs at the apical meristem

Step-by-step explanation:

This is a simple and quick question to solve

years later after the tree is now thirty feet high,  The barbed wire has been initially stapled at a height of five feet.

Consider the vectors x=(1,2,3,4) and y=(4,2,4,5) in R4 . Find the angle between them.
Law Incorporation [45]

Answer:

Angle between the two vectors is 20.7718°.

Step-by-step explanation:

The given two vectors are x = (1,2,3,4) and y = (4,2,4,5)

Now the dot product between two vector is defined as

x.y = ║x║║y║cosθ

Now, x.y( dot product of x and y) = 1×4 + 2×2 + 3×4 + 4×5 = 40

║x║= \sqrt{1+4+9+16} = \sqrt{30}

║y║= \SQRT{16+4+16+25} = \sqrt{61} '

Thus, we get

40 = \sqrt{30}×\sqrt{61}×Cos θ

Thus, Cos θ = \frac{40}{\sqrt{30}\sqrt{61}}

Cos θ = 0.935

θ = Cos^{-1} (0.935)

θ = 20.7718°
