Sin404 = sin(360 + 44)
as sin(360 + α) = sinα
= sin44
Answer:
0.72
Step-by-step explanation:
first you take 1.60 and find 10 percent of it once you find that you times it by 4.5.
Angle 1: 50
angle 2: 130
angle 3: 50
angle 4: 130
angle 5: 40
angle 6: 140
angle 7: 90
angle 8: 140
(0,-100) should be your answer, but do some research beforehand. If my answer is incorrect, please tell me so-- I'll try to correct my answer.
Answer:
1. zeros are -2 and 1
2. zeros are -1 and 3
3. zeros are -3 and 1
4. zeros are -1
5. no zeros
6. no zeros
Step-by-step explanation:
Zeros are points on the graph that are x-intercepts; in the graph we can see that they cross -2 and 1 on the 1st equation, -1 and 3 on the 2nd equation, -3 and 1 in the 3rd equation, and -1 in the 4th equation. Since it intersects no x-intercepts in the 5th and 6th equation, it has no zeros.
