Answer:
4) J
5) D
Step-by-step explanation:
4) 416 = 2x² - 6x
2x² - 6x - 416 = 0
x² - 3x - 208 = 0
x² - 16x + 13x - 208 = 0
x(x - 16) + 13(x - 16) = 0
(x - 16)(x + 13) = 0
x = 16, -13(not possible)
So 16 rows
5) y = a(x - h)² + k
y = a(x - 3)² - 7
When x = 1, y = -10
-10 = a (1 - 3)² - 7
-10 = 4a - 7
4a = -3
a = -¾
y = -¾(x - 3)² - 7
Answer:
8:1
Step-by-step explanation:
the actual table's height in inches is 4*12 = 48 inches.
48/6 = 8
so the ratio is 8:1.
