Answer:f(x)=−4(x2−6x+9−9)−29
(x2−6x+9)=(x−3)(x−3)
f(x)=−4((x−3)2−9)−29
f(x)=−4(x−3)2−4(−9)−29
f(x)=−4(x−3)2+36−29
f(x=−4(x−3)2+7
f(x)=−4(x−3)2+7
That's the equation we got by completing the square.
y=a(x−h)2+k
That's the formula of a parabola in "vertex" form. Notice the similarity? The two are equal if we say
y=f(x)
a=−4
h=3
k=7
Therefore the answer is C, −4(x − 3)2 + 7; The maximum height of the water is 7 feet.hopes this helps
Answer:
20
Step-by-step explanation:
factors of 20 = 1 2 4 5 10 20
factors of 40 = 1 2 4 5 8 20 10
therefore 20 is the greatest common

Thats just what a double dijet number is
Step-by-step explanation:
Combine like terms on left hand side. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.
⟼ 
⟼ 
Transpose 2x to left hand side and change it's sign.
Similarly , Transpose 10 to right hand side and change it's sign.
⟼ 
⟼ 
Divide both sides by 6
