Answer: b=40
Step-by-step explanation:
Answer:
3. Option 2 (Perpendicular)
4. Option 3 (neither)
Step-by-step explanation:
3.
m1 = -7/8
Second equation: -8x + 7y = -21
7y = 8x - 21 y = (8/7)x - 3
m2 = 8/7
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-7/8)(8/7) = -1,
They are Perpendicular
4.
m1 = -1/4
Second equation: -2x + 8y = 6
8y = 2x + 6 y = (1/4)x + 3/4
m2 = 1/4
m1 & m2 are not equal, so not parallel
Since m1×m2 = (-1/4)(1/4) = -1/16, not -1. They are not Perpendicular either. So, neither
Answer:
C. 1.21 I think
Step-by-step explanation:
Answer:
The height is 3.625ft.
Step-by-step explanation:
0.5x8xa=14.5
4a=14.5
a=14.5/4=3.625
5 times 2/6 is 10/6
You can simplify that to 5/3
