Solve the equation 4c2 + 7c – 5 = 0 using the quadratic formula

sergiy2304 [10]

4c2 + 7c – 5 = 0 a=4 b=7 c=-5

x = [-b +-sq root (b^2 -4ac)] / 2a

x = [-7 +-sq root(7^2 -4*4*-5)] / 2*4

x = [-7 +-sq root(49 + 80)] / 8

x = [-7 +-5.5677643628] /8

x1 = 0.544727125

x2 = -2.294727125

For the sequence 3n - 1, generate the first three terms.

Hunter-Best [27]

3n - 1

When n = 1,

3n - 1 = 3*1 - 1 = 3 -1 = 2

When n = 2,

3n - 1 = 3*2 - 1 = 6 -1 = 5

When n = 3,

3n - 1 = 3*3 - 1 = 9 -1 = 8

Hence, the first three terms are 2, 5 and 8.

The area of the regular octagon is approximately 54 cm2. A regular octagon has an apothem with length 4 centimeters and an area

ExtremeBDS [4]

Answer:

The length of line segment AB = 3.4 cm.

Step-by-step explanation:

Given:

The area of the regular octagon is approximately = 54 cm²

A regular octagon has an apothem with length = 4 cm

AB = side of the octagon

To Find:

AB = side of the octagon = ?

Solution:

A regular octagon has an Eight equal Side

We Know that,

$\textrm{area of regular octagon}=\textrm{Perimeter}\times \frac{Apothem}{2}$

substituting the given values in equation we get

$54 = Perimter\times \frac{4}{2}\\ \\\therefore Perimeter=\frac{54}{2}\\ \\\therefore Perimeter = 27\ cm\\$

Now,

Perimeter = 8 × Side

∴ Perimeter = 8 × AB

∴ 27 = 8 × AB

∴ $AB =\frac{27}{8}\\ \\\therefore AB =3.375\ cm\\\\$

After rounded to nearest 10th we get

AB =3.4 cm

The length of line segment AB = 3.4 cm.
