Determine the next step for solving the quadratic equation by completing the square. 0 = –2x2 + 2x + 3 –3 = –2x2 + 2x –3 = –2(x2
VLD [36.1K]
We have that
0 = –2x²<span>+ 2x + 3
</span>

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(–2x²+ 2x)=-3

Factor the leading coefficient 

-2*(x²-x)=-3

Complete the square. Remember to balance the equation by adding the same constants to each side

-2*(x²-x+0.25)=-3-0.50

Rewrite as perfect squares

-2*(x-0.5)²=-3.50

(x-0.5)²=-3.50/-2

(x-0.5)²=1.75------> square root both sides

(+/-)(x-0.5)=√7/2

(+)(x-0.5)=√7/2----> (√7/2)+0.5----> x=1.823

(-)(x-0.5)=√5/2-----> x=0.5-(√7/2)----> x=-0.823

the solutions are

x=1.823

x=-0.823

This figure represents a small weight that is to be covered on all sides with a floral fabric. How much fabric is needed to cove
Anon25 [30]

Answer:

77.5 cm²

Step-by-step explanation:

We need to find the surface area of the rectangular prism.

Total surface area = 2(lw + wh + lh)

where:

  • l = length of base
  • w = width of base
  • h = height of prism

Given dimensions:

\textsf{length}=\sf 6\dfrac12\:cm=6.5\:cm

\textsf{width}=\sf 2\dfrac12\:cm=2.5\:cm

\textsf{height}=\sf 2\dfrac12\:cm=2.5\:cm

Substituting these value into the formula:

\begin{aligned}\textsf{Surface area} & =\sf 2(6.5 \cdot 2.5+2.5 \cdot 2.5+6.5 \cdot 2.5)\\ & = \sf2(16.25+6.25+16.25)\\ & = \sf 2(38.75)\\ & =\sf77.5\:cm^2 \end{aligned}

Therefore, 77.5 cm² of fabric is needed to cover the weight.

Solve sin2theta=2sinthetacostheta​
pashok25 [27]

Answer:

\sin(2\theta) =2 \sin \theta \cos \theta proved

Step-by-step explanation:

Given

\sin2 \theta=2 \sin\theta cos\theta

Required

Prove

Proving from left to right.

\sin(2\theta) = \sin(\theta+\theta)

In trigonometry

\sin(A+B) = \sin A \cos B+\sin B \cos A

When this formula is applied to:\sin(2\theta) = \sin(\theta+\theta)

We have:

\sin(2\theta) = \sin \theta \cos \theta+\sin \theta \cos \theta

\sin(2\theta) =2 \sin \theta \cos \theta
