Answer:
(a) (-11.818, 2.084)
(b) (2.911, 2.443)
(c) (-14.387, -13.893)
Step-by-step explanation:
The generic expression for component form is ...
components = magnitude(cos(angle), sin(angle))
For repeated calculations, it works well to use a suitable calculator or spreadsheet.
(a) 12.0(cos(170°), sin(170°)) ≈ (-11.818, 2.084)
__
(b) 3.80(cos(40°), sin(40°)) ≈ (2.911, 2.443)
__
(c) 20.0(cos(224°), sin(224°)) ≈ -14.387, -13.893)
_____
In the attachment, the calculator is treating these as complex numbers. The component marked with "i" is the component in the y-direction.
Answer:
32 degrees
Step-by-step explanation:
All angles in a triangle add up to 180.
118 + 30 = 148
To find what's missing, subtract that from 180.
180 - 148 = 32 degrees
Hope this helped. :)
Y - 12 = -6 (x - 5)
y = -6x + 42
Answer:
I may be wrong but I think 8 is your answer.
Step-by-step explanation:
(-1)^(3/7) x 128^(3/7)
-1 x 128^3/7
128^(3/7) = 8
= 8
Answer: according to spark notes: There can be 0, 1, or 2 solutions to a quadratic equation, depending on whether the expression inside the square root sign, (b2 - 4ac), is positive, negative, or zero. This expression has a special name: the discriminant.
In this case it is 0, not 2, which was my first and wrong answer
