The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by: P(x)=-12x^2 +12
Minchanka [31]

Given:

The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by:

P(x)=-12x^2+120x

To find:

The current that will produce the maximum power.

Solution:

We have,

P(x)=-12x^2+120x

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 f(x)=ax^2+bx+c, then

Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)

In the given function, a=-12 and b=120. So,

-\dfrac{b}{2a}=-\dfrac{120}{2(-12)}

-\dfrac{b}{2a}=-\dfrac{120}{-24}

-\dfrac{b}{2a}=5

Putting x=5 in the given function, we get

P(5)=-12(5)^2+120(5)

P(5)=-12(25)+600

P(5)=-300+600

P(5)=300

Therefore, 5 watt current will produce the maximum power of 300 amperes.

8/6 = x + 2/32<br><br>Solve for X <br><br>Show work and answer can't be put into decimal form
yuradex [85]
<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

Find the tangent ratio of angle Θ. Hint: Use the slash symbol ( / ) to represent the fraction bar and enter the fraction with no
TiliK225 [7]

Answer:

Tangent ratio of the angle \theta is 15/8.

Step-by-step explanation:

Given:

AB = 15 unit

CB = 17 unit

AC = 8 unit

To find: Tangent ratio of angle \theta

We known that Tangent Ration is equal to the ration of Opposite side of the angle to the adjacent side of the triangle.

So,

tan\,\theta=\frac{AB}{AC}

tan\,\theta=\frac{15}{8}

Therefore, Tangent ratio of the angle \theta is 15/8.
