Find the zeros in the function 3x2+ 6 = 0

Mathematics
1 answer:
sattari [20]4 years ago
5 0

Answer:

x = ± i \sqrt{2}

Step-by-step explanation:

Given

3x² + 6 = 0 ( subtract 6 from both sides )

3x² = - 6 ( divide both sides by 3 )

x² = - 2 ( take the square root of both sides )

x = ± \sqrt{-2}

  = ± \sqrt{2(-1)}

  = ± (\sqrt{2} × \sqrt{-1}) → \sqrt{-1} = i

  = ± i \sqrt{2}

Inside a triangle, all inside angles add up to 180°

So, add the two angles:

180°-60.1°=119.9°

b=119.9°

An employee of a store's gift wrapping center is wrapping 8 gifts
Hitman42 [59]
<h3>Part A:</h3>

The area A of a rectangle is A = bh, where b is the base of the rectangle and h is the height. The area of each rectangle with side lengths 1.5 ft and 2 ft is 1.5 × 2 = 3ft2. Since there are two rectangles with these dimensions, the combined area is 2 × 3 = 6 ft2. The area of each rectangle with side lengths 1.5 ft and 2.5 ft is 1.5 × 2.5 = 3.75 ft2. The area of each rectangle with side lengths 2 ft and 2.5 ft is 2 × 2.5 = 5 ft2. Since there are two rectangles of each type, the combined area is 2 × 3.75 + 2 × 5 =17.5 ft2. <u><em>So, the total surface area of the box is 6 ft2+ 17.5 ft2 = 23.5 ft2</em></u>

<u><em></em></u>

<h3>Part B:</h3>

The employee needs to wrap 8 boxes, each with a surface area of 23.5 ft2. So, the combined surface area needing to be wrapped is 8 × 23.5 = 188 ft2. Since there is only 160 square feet of wrapping paper left, the employee will not be able to wrap all of the gifts
