Question 1: Identify the zeros of the function f(x) = 4x2 − 8x − 1 using the Quadratic Formula. Answers: -1/2 + sqaureroot 5, 1/
Lelechka [254]

Answer:

1.  1/2 +/-√5

2.  1 +/-  i √6/2.

Step-by-step explanation:

1.  f(x) = 4x^2 - 8x - 1

x = [-(-8) +/-√((-8)^2 - 4*4*-1)] / (2*4)

x =[ 8 +/- √80] / 8

= 1 +/- 4√5/8

= 1 +/- √5/2

= 1/2 +/-√5

2. By a similar method the zeros of the the second equation are:

x = [-(-4) +/- √((-4)^2 - 4*2*5)]  / 4

= 4 +/- √(16 - 40) / 4

= 1 +/- √(-24)/4

= 1 +/- i  √6 * 2 / 4

= 1 +/-  i √6/2.

Find the diamter of a circle if its area is 706.9mm²​
Masteriza [31]

Answer:

<h2>30 mm</h2>

Step-by-step explanation:

The formula of an area of a circle:

A=\pi r^2

<em>r</em><em> - radius</em>

<em />

We have

A=706.9\ mm^2

Substitute:

\pi r^2=706.9          <em>divide both sides by π</em>

r^2=\dfrac{706.9}{\pi}        <em>use π ≈ 3.14</em>

r^2\approx\dfrac{706.9}{3.14}\\\\r^2\approx225\to r=\sqrt{225}\\\\r= 15\ mm

The diameter <em>d = 2r</em>.

Therefore

d=2(15)=30\ mm
