Change -40° to radians.<br><br><br> A). 2π/9<br><br> B). -2π/9<br><br> C). 4π/9<br><br> D). -4π/9
Inessa05 [86]
To solve this, we are going to multiply our degrees by a conversion factor. Remember that 1°=\frac{ \pi }{180}, so to convert -40° to radians, we are going to multiply -40° by the conversion factor \frac{ \pi }{180}; that way we can cancel degrees and express our answer in radians:

(-40°)(\frac{ \pi }{180} )= -\frac{2 \pi }{9}

We can conclude that the correct answer is: <span>B). -2π/9</span>

------   =  -------

100        382

45 x 382 = 17190      100 · x = 100x

17190 ÷ 100x = 171.9 = x

** Which of the following is parallel to the line 2x + 4y = 16 (A) y = 2x + 5 (B) y = -x + 4 (C) y = -x + 8 (D) y = 2x + 5 =-​
andreev551 [17]

Answer:

None of them.

Step-by-step explanation:

Each and every straight line is of one kind in terms of its pattern: it can be presented in the view of y = kx + b: k is the slope or gradient of the line, b is the y-intercept of the line. I will not let the cat out of the bag if I say that any parallel lines do not intersect one another, hence they should have the same value of coefficient k.

2x + 4y = 16 \Leftrightarrow x + 2y = 8 \Leftrightarrow 2y = -x + 8 \Leftrightarrow y = - \frac{1}{2}x + 4

Therefore, our line has k = - \frac{1}{2} and b = 4 coefficients.

(A) k = 2, b = 5;

(B) k = -1, b = 4;

(С) k = -1, b = 8;

(D) k = 2, b = 5;

Recapitulating this: none of them have the same coefficient k, thus none of them suit us.
