Answer:
Step-by-step explanation:
7y⁴ = 7y²(z - 3ax)
Divide both sides by 7y².
y² = z - 3ax
Add 3ax to both sides. Subtract y² from both sides.
3ax = z - y²
Divide both sides by 3a.

The answer is d because it’s right
Answer:
i got -45, so make sure you wrote the problem right because i solved correctly.
Answer:
The value of cos 0 = - 2 sqrt(85) / 85 = - 0.216930458
Step-by-step explanation:
cos 0 = ?
Point on the terminal side of 0 : (-2,9)=(x,y)→x=-2, y=9
cos 0 = x/r
r=sqrt(x^2+y^2)
Replacing the known values:
r=sqrt( (-2)^2+(9)^2)
r=sqrt(4+81)
r=sqrt(85)
cos 0 = x/r
cos 0 = -2 / sqrt(85) = -2/9.219544457 = -0.216930458
Rationalizing:
cos 0 = -[2 / sqrt(85)] [sqrt(85) / sqrt(85)]
cos 0 = - 2 sqrt(85) / [sqrt(85)]^2
cos 0 = - 2 sqrt(85) / 85
