Answer:
(-12, 12) D
Step-by-step explanation:
Substitute y = 12 into the first equation:-
12 = -3/4x + 3
-3/4 x = 12 - 3 = 9
x = 9 * -4/3
= -12
so the answer is (-12, 12)
The Cartesian equivalent of the polar coordinates (r, theta) is
(r cos t, r sin t), where t = theta.
So, (2, 3pi/4) becomes
(2 cos(3pi/4), 2 sin(3pi/4))
(2 • -sqrt{2}/2, 2 • sqrt{2}/2)
Answer: (-sqrt{2}, sqrt{2})
Done.
Note: sqrt = square root for short.
Answer:
81 hours
Step-by-step explanation:
Let x be the time are needed
45:5 = x:9
5x = 45×9
5x = 405
x = 81
