Answer:
(1.5,-2.6)
Step-by-step explanation:
Given the polar coordinates (-3,60°).
Let our Cartesian coordinates be (x,y)
#We know that when converting the rectangular coordinates (x,y) to polar (r,θ), then:
#Using the illustration above, we can express our polar coordinates as:
#Solve simultaneously to solve for x and y:
Hence, the Cartesian coordinates are (1.5,-2.6)
Answer:
Yes
Step-by-step explanation:
There are 10 mm in 1 cm.
We have 300 mm, so let's convert this to cm by using a proportion:
, where x is the number of cm in 300 mm.
Cross-multiplying, we get: 10x = 300, so x = 30 cm.
Clearly, 30 cm > 3 cm, so yes, 300 mm is greater than 3 cm.
Hope this helps!
For this use the law of sines:
cross-multiply:
16×sin (J) = 11×0.97
sin(J) = 10.72/16
sin(J) = 0.67
