What is the image of (1,0) after a counterclockwise rotation of 60 degrees?

Anestetic [448]

Answer:

$\vec s = \left(\frac{1}{2},\frac{\sqrt{3}}{2} \right)$

Step-by-step explanation:

The coordinate has the following polar form:

$\vec r = (1, 0^{\circ})$

The image of the coordinate rotated counterclockwise 60° is:

$\vec s = (1, 60^{\circ})$

Its equivalent form in rectangular coordinates is:

$\vec s = (1\cdot \cos 60^{\circ}, 1 \cdot \sin 60^{\circ})$

$\vec s = \left(\frac{1}{2},\frac{\sqrt{3}}{2} \right)$

Find the sum of the first 8 terms in the sequence 2 8 32 128

Zigmanuir [339]

the sequence is in multiples of 4 (2*4=8, 8*4=32, 32*4=128)

so 128*4=512, 512*4=2048, 2048*4=8192 & 8192*4=32768

2+8+32+128+512+2048+8192+32768=43690

Why does 3+5=8 help you find 8-5

Nat2105 [25]

Answer:

Step-by-step explanation:

let me see if I can explain this...

3 + 5 = 8....those 2 numbers added together equals the total(8)...if u take the total(8) and subtract one of the numbers, it gives u the other number.

8 - 5 = 3 and 8 - 3 = 5

here's another one...

30 + 60 = 100

100 - 30 = 60 and 100 - 60 = 30
