Find the value of x. Round to the nearest degree.
kari74 [83]

Answer: x = 33 degrees

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle,

The length of the hypotenuse of the right angle triangle is 19

With x degrees as the reference angle,

The length of the adjacent side of the right angle triangle is 16

To determine x, we would apply trigonometric ratio

Cos θ = adjacent side/hypotenuse side. Therefore,

Cos x = 16/19 = 0.842

x = Cos^-1(0.842)

x = 33 degrees

E temperature t of a metal sphere is inversely proportional to the distance from the centre of the sphere (the origin (0, 0, 0))
olasank [31]

(-x, -y, -z) the vector form (x, y, z) to the origin, in the direction of the greatest increase.

<h3>How to calculate temperature?</h3>

The quantity or amount of radiation contained in material or item, as measured by a temperature or sensed by touch and stated on a numerical scale.

The temperature T of a ball bearing is inverse to the length first from the origin, which we consider to be the center of the ball. The temperature at the exact location

(x, y, z) is a point on the sphere, the temperature at this point is given by

T(x,y,z)= \dfrac{k}{(x^2 +y^2+z^2)^{1/2}}

Where k is constant, then we have

T(1, 2, 2) = k/3 = 170

k = 510

So

T(x,y,z)= \dfrac{510}{(x^2 +y^2+z^2)^{1/2}}

Then we have

\rm \triangledown T =  \left ( -\dfrac{510x}{(x^2 +y^2+z^2)^{1/2}}, -\dfrac{510y}{(x^2 +y^2+z^2)^{1/2}}, \dfrac{510z}{(x^2 +y^2+z^2)^{1/2}} \right )\\\\\\\triangledown T (1, 2, 2) = -\dfrac{510}{27} (1, 2, 2) =-\dfrac{170}{9} (1, 2, 2)

Then the direction will be from (1, 2, 2) to (4, 3, 5) will be (3, 1, 3)

So u = (3/√19, 1/√19, 3/√19)

Then we get

\rm \triangledown T \cdot u = \dfrac{-170}{9}(1, 2, 2) \cdot \left (\dfrac{3}{\sqrt{19}}, \dfrac{1}{\sqrt{19}}, \dfrac{3}{\sqrt{19}} \right )\\\\\\\triangledown T \cdot u = - \dfrac{170}{9\sqrt{19}} (3 + 2 + 6)\\\\\\\triangledown T \cdot u = -\dfrac{1870}{9\sqrt{19}}

The direction of the greatest inverse in the temperature is given by any vector parallel to and having the same direction \triangledownT. (-x, -y, -z) the vector form (x, y, z) to the origin, in the direction of the greatest increase.

What is the axis of symmetry for f(x)=5(x+7)(x-5)
Harman [31]
<span>What is the axis of symmetry for f(x)=5(x+7)(x-5)?  Multiply out this polynomial to obtain the equation of a parabola in the form y = ax^2 + bx + c.

f(x) = 5(x^2 - 5x + 7x -35)

Holding the coefficient 5, we have 1x^2 - 2x - 35.  Here a = 1 and b = -2, and
thus x = -b / (2a) provides the x-coord. of the axis of symm.  It is:

x = -(-2) / (2*1) = 1.

The axis of symmetry is the vertical line x = 1.</span>
