Find the value of b. B² = 256

Jlenok [28]

$B^2=256$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$B=\sqrt{256},\:B=-\sqrt{256}$

$\sqrt{256}$

$\mathrm{Factor\:the\:number:\:}\:256=16^2$

$=\sqrt{16^2}$

$=16$

$-\sqrt{256} =-16$

$B=16,\:B=-16$

ASAP PLEASE! A windshield wiper blade turns through an angle of 135 degrees. The bottom of the blade traces an arc with a 9-inch

zysi [14]

Answer:

33 inches to the nearest inch.

Step-by-step explanation:

Length of an arc = rC where r = the radius and C is the angle through which it turns in radians.

So for the 23 inch radius: length = 23 * 135 * π / 180

and for the 9 inch radius: length = 9 * 135 * π / 180

The difference = 23 * 135 * π / 180 - 9 * 135 * π / 180

= 14 * 135 * π / 180

= 32.99 inches.
