Given:
The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by:
To find:
The current that will produce the maximum power.
Solution:
We have,
Here, leading coefficient is negative. So, it is a downward parabola.
Vertex of a downward parabola is the point of maxima.
If a parabola is 
, then
In the given function, a=-12 and b=120. So,
Putting x=5 in the given function, we get
Therefore, 5 watt current will produce the maximum power of 300 amperes.

The answer is 9.37 when it is rounded up.
if i helped can i get a brainiest answer please
<span>8/6 = x + 2/32
To solve this, you need to subtract 2/32 from both sides. To do that though, the two fractions need to have a common denominator.
2/32 can be simplified to 1/16.
The lowest denominator they have in common is 48.
1/16 = 3/48
8/6 = 64/48
Now subtract them.
</span>(64/48) - (3/48) = 61/48
That cannot be simplified, so it's the final answer.
x = 61/48
Answer:
Tangent ratio of the angle 
is 15/8.
Step-by-step explanation:
Given:
AB = 15 unit
CB = 17 unit
AC = 8 unit
To find: Tangent ratio of angle
We known that Tangent Ration is equal to the ration of Opposite side of the angle to the adjacent side of the triangle.
So,
Therefore, Tangent ratio of the angle is 15/8.
