f(x)=x^2+12x+26
Vertex form of f(x) = a(x-h)^2 +k
We change f(x) into vertex form using completing the square method
We take half of square of middle term
middle term is 12
Half of square of 12 is then 6^2 = 36
Add and subtract 36 to complete the square
The vertex form
Answer:
Step-by-step explanation:
We have F´ =500 and =30º, so x and y components:
F´ = this is
;
Finally
F' =
