Lake County’s smallest forest preserve is 472 acres. Orange County’s smallest preserve is 482 acres
Lake County’s smallest forest = 472
Orange County’s smallest = 482
To find ratio we make a fraction
Ratio = Lake County’s forest / Orange County’s forest
=
Now simplify the fraction
divide top and bottom by 2
Ratio is 236 : 241
Answer:
Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
= - ← subtract numerators leaving the common denominator
=
=
= ← cancel common factor (y - 1) on numerator/denominator
=

Answer:
a) x-intercepts are (0,0) and (5,0)
b) 6.25 yards
Step-by-step explanation:
a) x intercepts are:
-x² + 5x = 0
-x(x - 5) = 0
x = 0, 5
b) -x² + 5x
-(x² - 5x)
-[x² - 2(x)(5/2) + (5/2)² - (5/2)²]
-(x - 5/2)² + 25/4
Max height is:
25/4 yards or 6.25 yards
