Answer:
D. -2 ≤ y ≤ 3
Step-by-step explanation:
This is because range is based on y-values and so the lowest y-value here is -2 and the greatest one is 3, inclusive.
Answer:0.8
Step-by-step explanation:To write 24/30 as a decimal you have to divide numerator by the denominator of the fraction. We divide now 24 by 30 what we write down as 24/30
X = 6 cos(t)
y = 3 sin(t)
we can rewrite these equations as:

Taking squares of both equations we get:

Adding both the equations, we get:
4x-2 bc a pos x neg = neg
