Convert the following angle measures to degrees. 1. π/6 2. 3π/5

astraxan [27]

Answer:

30° and 108°

Step-by-step explanation:

To convert from radian to degree measure

degree = radian measure × $\frac{180}{\pi }$

(1)

$\frac{\pi }{6}$ × $\frac{180}{\pi }$ = $\frac{180}{6}$ = 30°

(2)

$\frac{3\pi }{5}$ × $\frac{180}{\pi }$ = $\frac{3(180)}{5}$ = 108°

If x^3+ax^2-18x+b = (x+5)(x-4)(x+2) what is a and b

blondinia [14]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$(x + 5)(x - 4)(x + 2) =$

$(x + 5) ({x}^{2} - 2x - 8) =$

${x}^{3} - 2 {x}^{2} - 8x + 5 {x}^{2} - 10x - 40 = \\$

${x}^{3} + 3 {x}^{2} - 18x - 40$

_________________________________

Compare :

${x}^{3} + 3 {x}^{2} - 18x - 40$

${x}^{3} + a {x}^{2} - 18x + b$

Thus :

$a = 3$

and

$b = - 40$
