Write the equation of the parabola in vertex form.<br><br><br>Vertex: (−4,6); Point: (−2,−2)

gtnhenbr [62]

Answer:

y = - 2(x + 4)² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (- 4, 6 ) , thus

y = a(x - (- 4) )² + 6 , that is

y = a(x + 4)² + 6

To find a substitute (- 2, - 2) into the equation

- 2 = a(- 2 + 4)² + 6 ( subtract 6 from both sides )

- 8 = a(2)² = 4a ( divide both sides by 4 )

- 2 = a , thus

y = - 2(x + 4)² + 6 ← equation in vertex form

In this diagram, a rope is attached to a small pulley at the apex of an isosceles prism. What is the minimum length of the rope

madreJ [45]

Answer:

Minimum length of rope needed to span the sides of the prism is 10 units.

Step-by-step explanation:

Let us draw a perpendicular from apex to base BC,Let it be AD since ΔABC is isosceles triangle, that perpendicular will touch mid of base. That is BD=DC= $\frac{6}{2}$ =3

Now we know the angle m∠ABC as 53.13°.

From ΔADC, $cos(53.13)=\frac{DC}{AC} =\frac{3}{(\frac{r}{2} )}$

$cos(53.13)=\frac{6}{r}$

$r=\frac{6}{cos(53.13)} = 9.999$ ≈10

Hence minimum length of rope needed to span the sides of prism is 10 units.
