Answer:
see below
Step-by-step explanation:
The component form of the polar coordinate pair (r, θ) is ...
(r, θ) ⇔ (r·cos(θ), r·sin(θ))
Then your point (2, 60°) translates to ...
(2, 60°) ⇔ (2·cos(60°), 2·sin(60°)) = (2(1/2), 2(√3)/2) = (1, √3)
Answer:
40%
Step-by-step explanation:
You subtract 11,970-8,550 = 3,420 to isolate the increase.
Divide 3,420/8,550 = .4 to get the percent increase of the markup.
The answer is .4 or 40% (they are equivalent)
You can check my work by multiplying 8,550 * .4 = 3,420
This answer is the percent of 8,550 that it increased (40% of 8,550) so make sure that is what the question is asking. If it is then it's your answer.

Answer: This means it would take 4 seconds for the leaf to fall 1 foot.
Step-by-step explanation: The leaf starts at 12 feet above the ground. This eliminates the first and third graph, leaving the second and last. The leaf falls at 0.25 ft/sec. This means it would take 4 seconds for the leaf to fall 1 foot.
