Answer:
1) 0, 180
2) 90
3) 3pi/2
4) pi/2, -3pi/2
5) 90, 270
6) 0
7) pi
8) -2pi, 0, 2pi
Step-by-step explanation:
1) sinx = 0
x = 0, 180, 360
2) sinx = 1
x = 90
3) sinx = -1
x = 270 or 3pi/2
4) sinx = 1
x = pi/2, pi/2 - 2pi = -3pi/2
5) cosx = 0
x = 90, 360
6) cosx = 1
x = 0, 360
7) cosx = -1
x = pi
8) cosx = 1
-2pi, 0 , 2pi
Answer:
true
Step-by-step explanation:
if an object is losing heat energy, it turns cold, and can turn into a solid, for example, water turning into ice. If you apply heat on ice, it's turns back to water. IF you apply heat to water, it vaporizes, and turns into gas.
Step one: Subtract $15 - $5.50 = $9.50
<span>Step two: divide $9.50 ÷ $15 = .633 (rounded) </span>
<span>Step three: Multiply .633 * 100 to change it to a percent. It becomes 63.3% (rounded) </span>
<span>The decrease is 63.33% </span>
<span>Proof: $15 * .63333 = $9.50 </span>
<span>Subtract $15 - $9.50 = $5.50
