2.6345 e7
Answer:
Step-by-step explanation:
your basically multiplying everything in the first parenthesis by everything in the second parenthesis
(x + 4y + z)(x - 7y) =
x(x - 7y) + 4y(x - 7y) + z(x - 7y) =....keep in mind, 4yx is the same as 4xy
x^2 - 7xy + 4xy - 28y^2 + zx - 7zy....combine like terms
x^2 - 3xy - 28y^2 + zx - 7zy <---- your answer
this is the distributive property

Therefore, the answer is
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
