Answer:
314.16
Step-by-step explanation:
area = pi x r2. 3.14 x 100 = 314.16
Answer:
(- 3, - 13 ) and (8, 1 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Both equations are in vertex form
(8)
y = 5(x + 3)² - 13
with vertex = (h, k) = (- 3, - 13 )
(9)
y = (x - 8)² + 1
with vertex = (h, k) = (8, 1 )
