The crest of this parabola is at (3,5) when the y-value is 6 the x value -1 what is the coefficient that the squared hatchet in the
x= -1, y=6
Simply,eqn that parabola is given by ax^2+bx+c=y
So, coefficient that squared hatchet (x^2) is "a"
Therefore, we"ve to discover the value of a
Moving on to solution:
a-b+c=6 ___(i) (by putting the given values of x and y in eqn of parabola )
We know that,
Vetex=(-b/2a, ( 4ac-b^2)/4a)
(3,5) = (-b/2a , (4ac-b^2)/4a)
Equating equivalent sides,we get
5=(4ac/4a) - (b^2/4a)
5= c- (36a^2/4a) (by putting value of b from eqn ii )
Now,moving back to the an initial eqn
Hence ,the compelled value that coefficient that squared term is 1/16.

I tried my best to give clear explanation as much as I know. It"s just we"ve have to find the value of a .

Raj created - (5^4) = ( – 5)^4 is Raj correct? Why or why not?
This is False / incorrect
because one side is positive and the various other one negative

7. Heather’s weekly salary is straight proportional to the number of hours she works at the insurance money agency. She pay is $174 for 2
174 split by 24 is 7.25 (which is how much Heather works each hour)
Then multiple 40 x 7.25 to get your positiveeast.org of $290
