Step-by-step explanation:
According to the question, sin (0) is (-)ve
therefore, sin(0)= -15/17
AND , tan(0) = sin(0) / cos(0)
= 15/8
Answer:
4x -8+4y
Step-by-step explanation:
4(x - 2 + y)
Distribute
4*x -4*2 +4*y
4x -8+4y
Answer:
the irrational numbers are all the real numbers which are not rational numbers.
Step-by-step explanation:
Remember
xyz=(x)(y)(z)
if x and y and z are all perfect cubes, xyz is also a perfect cube
remmeber
(x^n)^m=x^(mn)
so if it is perfect cube it can be factored into
(x^n)^3, such taht n is a whole number
basiclaly, see if the expoent is divisble by 3
all of them should be perfect cubes
215x^18y^3z^21
split them up to see which ones need changing
215=5*43, not a perfect cube
could be changed to 6^3, which is 216
x^18=(x^6)^3
y^3=y^3
z^21=(z^7)^3
the 215 needs to be changed
