Step-by-step explanation:
use the formula √(x2-x1)^2+(y2-y1)^2
Answer:
The angle of rotation is 214°.
Step-by-step explanation:
Formula for arc length:
The length of arc is the product of radius and the central angle ( in radian).
L= rθ
L= Length of arc
r= Radius
θ= Central angle (in radian).
Here L= 280 feet and diameter =150 feet.
Radius
feet =75 feet
L= rθ
![\Rightarrow \theta =\frac{L}{r}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%20%3D%5Cfrac%7BL%7D%7Br%7D)
radian.
We know that,
π radian= 180°
![\Rightarrow 1 \ radian= \frac{180^\circ}{\pi}](https://tex.z-dn.net/?f=%5CRightarrow%201%20%5C%20radian%3D%20%5Cfrac%7B180%5E%5Ccirc%7D%7B%5Cpi%7D)
![\Rightarrow \frac{280}{75} \ radian = \frac{180^\circ}{\pi}\times \frac{280}{75}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B280%7D%7B75%7D%20%5C%20radian%20%3D%20%5Cfrac%7B180%5E%5Ccirc%7D%7B%5Cpi%7D%5Ctimes%20%20%5Cfrac%7B280%7D%7B75%7D)
= 214°
The angle of rotation is 214°.
Answer: N >/= 7 bits
Minimum of 7 bits
Step-by-step explanation:
The minimum binary bits needed to represent 65 can be derived by converting 65 to binary numbers and counting the number of binary digits.
See conversation in the attachment.
65 = 1000001₂
65 = 7 bits :( 0 to 2^7 -1)
The number of binary digits is 7
N >/= 7 bits
