Answer:
Step-by-step explanation:
Recall that cos Ф = adj / hyp. If adj = 6 and hyp = 10, then by the Pythagorean Theorem, opp = 8: 6² + 8² = 10²
Then:
sin Ф = opp / hyp = 8/10 or 4/5
cos Ф is given: 6/10 or 3/5
tan Ф = opp / adj: 8/ 6 or 4/3
cot Ф = 1/sin Ф = 10/8 or 5/4
sec Ф = 1/ cosФ = 10/6 or 5/3
csc Ф = 1 / sin Ф = 10/8 or 5/4

Answer:
y = 7
Step-by-step explanation:
The slope is ...
m = (7 -7)/(0 -4) = 0
The y-intercept is the point (0, 7), so the slope-intercept equation is ...
y = mx +b
y = 0·x +7
Simplifying this puts it in standard form:
y = 7
Answer: Options 1, 3, 5
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals, so since the slope of the given line is 1/3, we need to find lines with a slope of -3.
- Option 1 has a slope of -3.
- Option 2 has a slope of 3.
- Option 3 has a slope of -3.
- Option 4 has a slope of 1/3.
- If we subtract 3x from both sides, we get y=-3x+7, so option 5 has a slope of -3.
