Answer:

(D)

Step-by-step explanation:

It is given that Kite WXYZ has a short diagonal of XZ and a long diagonal of WY. The diagonals intersect at point V. The length of XZ = 8cm, and the measure of ∠XYV is 30°.

We know that, in Kite, the diagonals are the perpendicular bisectors, therefore ∠V=90° and XZ=8⇒XV=4cm

Now, from ΔXVY, we have

\frac{XV}{VY}=tan30^{\circ}

⇒\frac{4}{VY}=\frac{1}{\sqrt{3}}

⇒VY=4\sqrt{3}cm

Therefore, the length of the segment VY is 4\sqrt{3}cm.

XV = 8 cm and angle XYV = 30

Tangent (XYV) = XV / VY
Tangent (30) = 4 cm / VY
VY = 4 cm / 0.57735
VY = <span> <span> <span> 6.9282064606 cm </span> </span> </span>

= 4 * square root (3)

Which function's graph has x-intercepts at x=−1 and x=3, and a vertex at point (1,−4)?
Luda [366]

Answer:

Top right option: g(x) = (x+1)(x-3)

Step-by-step explanation:

x=-1 is the solution to x+1=0

x=3 is the solution to x-3=0

Therefore, your expression so far is (x+1)(x-3) or x²-2x-3.

Since the vertex must be (1,-4) we must check if x=1 satisfies the equation x=-b/2a:

x=-b/2a

1=-(-2)/2(1)

1=2/2

1=1

Both sides are equal to each other, so the final function is g(x) = (x+1)(x-3)
