Answer:
Step-by-step explanation:
hello
so to know the maximum to y we can check the maximum of
f(x)=
f is derivable and f'(x)=6-2x
f'(x)=0 <=> x = 3
so the maximum is reached for x = 3
f(3)=18-9=9
and then
to be rigorous, we can write the variation table of y to show that there is only one maximum
hope this helps
Answer: The distance is sqrt(40).
Step-by-step explanation:
Let's use the Pythagorean Theorem (a^2 + b^2 = c^2)
(Look at the image I attached)
Let's set a = 2 and b = 6. The mystery side is c, which is opposite to the right angle that is formed when you draw perpendicular lines from each of the points.
(2)^2 + (6)^2 = c^2 <--- First, we need to simplify
4 + 36 = c^2
40 = c^2 <--- Now, we need to take the square root of both sides.
c = sqrt(40)
So, the distance between (5, -4) and (-1, -2) is sqrt(40). I recommend looking at some videos on Khan Academy if you need more help! Let me know if you want me to attach a link that you can visit.

Answer:
=x^2 -14xy+49y^2
Step-by-step explanation:
(x − 7y)^2
= (x-7y)(x-7y)
= x^2 -7xy-7xy+49y^2
=x^2 -14xy+49y^2
Hello,
The answer is x<-2 is the answer.
Hope this helps
