Answer:
Step-by-step explanation:
In general (x, y, z) = (p ·cos s ·sin t, p· sin s· sin t, p · cos t) where p is radius
x(s, t)= 3 ·cos s ·sin t
y(s, t)= 3· sin s· sin t
z(s, t) = 3· cos t
Where, radius is 3, s ∈ [0,2π), and t ∈ [0, π]
Answer: (0,-1) and (1/3,0)

Answer:
12.60
Step-by-step explanation:
Start off by the total which is 18. To find the percentage off you will have to make the 30% into a decimal, so simply move it two spaces to the left. Now you have .30. Multiply the decimal, .30, and the full amount, 18. Your equation now should be (.30)*(18). Your answer will be 5.40. 5.40 is what is off of the shirt from the original price, so subtract 5.40 from 18. Your equation now is (18-5.40) which is 12.60.
Answer:
0.22
Step-by-step explanation:
So in this problem, we have to find the hypotenuse first, since sine is opposite over hypotenuse.
We can do this using the pythagorean theorem (you can search it if you don't know). Or, we can just remember this as one of our pythagorean triplets (9,40,41). The last side will be 41.
We have to find the value of sin(D)
opposite/hypotenuse = 9/41 = 0.2195 which is about 0.22
Answer: 0.75
Step-by-step explanation: you have to do 3 divided by 4 which gives you 0.75. To make sure your answer is right, you do 0.75 x 4 = 3
