Mathematics

storchak [24]3 years ago

For angles in first quadrant, the reference angle is itself. In second quadrant, the equation would be 180 - x where x is the measure of the angle. In third quadrant, x - 180. Lastly, in the fourth quadrant, the reference angle is 360 - x. From the second set of angles in the given, the reference angles are.
              (1) 135 ; RA = 180 - 135 = 45
              (2) 240; RA = 240 - 180 = 60
              (3) 270; RA = 90 (lies in the y - axis)
              (4) 330; RA = 360 - 330 = 30

What is the absolute value of -4/25
Y_Kistochka [10]

The absolute value of x: |x|.

|x| = x if x ≥ 0    <em>examples: |5| = 5; |0| = 0; |8.34| = 8.34; |1/2| = 1/2</em>

|x| = -x if x < 0   <em>examples: |-5| = -(-5) = 5; |-8| = -(-8) = 8; |-1.2| = 1.2;</em>

<em> |-3/7| = 3/7</em>

<em>Therefore</em>

<em>\left|-\dfrac{4}{25}\right|=\dfrac{4}{25}</em>

telo118 [61]
In a year there are 12 months
in 6 years there are 72 months
that means he paid a total of 72(225) = $16200
$16200 minus the original $15,000 he took out leaves us with the amount of interest he paid which is $1,200
therefore answer A is correct

Let f(x) = x + 9 + 2, find f(0), f(7), and f(-5).
wolverine [178]

Answer:

f(0) = 0 + 9 + 2

f(0) = 11

f(7) = 7 + 9 + 2

f(7) = 18

f(-5) = -5 + 9 + 2

f(-5) = 4 + 2

f(-5) = 6

thank you
