Answer:
,
Step-by-step explanation:
The function of the graph can be written in the vertex form as
, where V(h,k)=V(2,4) is the vertex of the quadratic function.
We substitute the value to obtain;
,
The point (5,1) lies on the graph so we use it to determine the value of a.
,
,
,
The required equation is
,
Answer:
1.30
Step-by-step explanation:
when it's rounding if the number is 5 or above you raise the number
Step-by-step explanation:
Left-hand-side:
\displaystyle \dfrac{1}{sec(x) - tan(x)}
sec(x)−tan(x)
1
\displaystyle = \ \dfrac{1}{sec(x) - tan(x)} * \dfrac{sec(x) + tan(x)}{sec(x) + tan(x)}=
sec(x)−tan(x)
1
∗
sec(x)+tan(x)
sec(x)+tan(x)
\displaystyle = \ \dfrac{sec(x) + tan(x)}{sec^2(x) - tan^2(x)}=
sec
2
(x)−tan
2
(x)
sec(x)+tan(x)
Now use
\displaystyle 1 + tan^2(x) \ = \ sec^2(x)1+tan
2
(x) = sec
2
(x)
and you should be done.....
