Recall that for all t,
cos²(t) + sin²(t) = 1
Now,
x = 5 cos(t) - 7 ⇒ (x + 7)/5 = cos(t)
y = 5 sin(t) + 9 ⇒ (y - 9)/5 = sin(t)
so that substituting into the identity above, we get
((x + 7)/5)² + ((y - 9)/5)² = 1
which we can rewrite as
(x + 7)²/25 + (y - 9)²/25 = 1
(x + 7)² + (y - 9)² = 25
and this is the equation of a circle centered at (-7, 9) with radius 5.

Answer:
The answer is A; H(a) = 3.00a +19.00; shift 15 units up
Step-by-step explanation:
If the downloading feature is enabled the cost function becomes H(a) = 3.00a + 19.00
The y-interpret of H(a) is 15 greater than the y-intercept if C(a)
The slopes of both functions are the same
