Answer:
y = 
x² - 2x + 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
From the graph (h, k) = (2, - 1), thus
y = a(x - 2)² - 1
To find a substitute a point on the curve (0, 1) into the equation
1 = 4a - 1 ( add 1 to both sides )
4a = 2 ( divide both sides by 4 )
a = 
= , hence
y = (x - 2)² - 1 ← in vertex form
Expand the factor and simplify
y = (x² - 4x + 4) - 1
= x² - 2x + 2 - 1
= x² - 2x + 1 ← in standard form
There are 9 number cards from 2 to 10 in a deck of cards.
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
There are 4 nines in a deck of 52 cards. We know that 4 x 9 = 36.
The chance or probability of taking out a 9 is (36/52).
Reducing this fraction to the lowest terms we get 9/13.
So 1.22 per large flower
200 large flowers
1.22 times 200=244 yards used
subtract
300-244=56
56=100 smal flowers
divide both sides by 100
0.56=1 small flower
the answer is 0.56 yards=1 flower
