Answer:

see explanation

Step-by-step explanation:

To find x use the sine ratio in the right triangle and the exact value

sin60° = \frac{\sqrt{3} }{2} , then

sin60° = \frac{opposite}{hypotenuse} = \frac{14\sqrt{3} }{x} = \frac{\sqrt{3} }{2} ( cross- multiply )

x \sqrt{3} = 28\sqrt{3} ( divide both sides by \sqrt{3} )

x = 28

-----------------------------------------------------------

To find y use the tangent ratio in the right triangle and the exact value

tan60° = \sqrt{3} , then

tan60° = \frac{opposite}{adjacent} = \frac{14\sqrt{3} }{y} = \sqrt{3} ( multiply both sides by y )

14\sqrt{3} = y \sqrt{3} ( divide both sides by \sqrt{3} )

y = 14

Find K: mx=p(z/x+k + 2s/y)
ivann1987 [24]

Answer:

-\frac{2s}{y} -\frac{z}{x} +\frac{mx}{p} =k

Step-by-step explanation:

mx=p(\frac{z}{x} +k+\frac{2s}{y} )- Divide by p

\frac{mx}{p} =(\frac{z}{x} +k+\frac{2s}{y} )- Subtract the 2 fractions

-\frac{2s}{y} -\frac{z}{x} +\frac{mx}{p} =k

Which could be the function?
sladkih [1.3K]

Answer:

f(x)=(x-4)^{2}

Step-by-step explanation:

we have that

The axis of symmetry shown in the graph is x=4

we know that

The axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex

so

<em>Verify each case</em>

<em>case a)</em> we have

f(x)=(x+4)^{2}

The vertex is the point (-4,0)

therefore

Cannot be the function

<em>case b)</em> we have

f(x)=x^{2}+4

The vertex is the point (0,4)

The axis of symmetry is x=0

therefore

Cannot be the function

<em>case c)</em> we have

f(x)=(x-4)^{2}

The vertex is the point (4,0)

The axis of symmetry is x=4

therefore

Could be the function

<em>case d)</em> we have

f(x)=x^{2}-4

The vertex is the point (0,-4)

The axis of symmetry is x=0

therefore

Cannot be the function
