A. 9

B. 24

C. 6

D. 16

Step-by-step explanation:

Given ratios are;

A. 2 : 3 = 6 : x

Product of mean = Product of extreme

6*3=2*x\\18=2x\\2x=18

Dividing both sides by 2

\frac{2x}{2}=\frac{18}{2}\\x=9

B. 4 : 7 = x : 42

Product of mean = Product of extreme

7x=168

Dividing both sides by 7

\frac{7x}{7}=\frac{168}{7}\\x=24

C. 2x : 48 = 3 : 12

Product of extreme = Product of mean

2x*12=48*3\\24x=144

Dividing both sides by 24

\frac{24x}{24}=\frac{144}{24}\\x=6

D. 12 : 15 = x : 20

Product of mean = Product of extreme

15*x=12*20\\15x=240

Dividing both sides by 15

\frac{15x}{15}=\frac{240}{15}\\x=16

The golden ratio is a solution to a quadratic equation.
Crank

Answer:

Below.

Step-by-step explanation:

a.    Φ^2 − Φ − 1 = 0

Φ2 − Φ = 1

(Φ - 0.5)^2 - 0.25 = 1

(Φ - 0.5)^2 = 1.25

Φ - 0.5 = √(1.25)      (We only take the positive root).

Φ  = 0.5 + √(1.25)

b. I used Completing the square.

c.  Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.

Find the 12th term of the arithmetic sequence given a3=116 and a7=180<br>​
SOVA2 [1]

Answer:

Step-by-step explanation:

nth term = a +(n-1)d

a3 = 116 ;   a + 2d = 116 ---------(i)

a7 = 180;   a + 6d = 180 -------(ii)

multiply (ii) by -1. so a will be eliminated

           a + 2d = 116 ---------(i)

(ii)*-1    <u>-a - 6d = -180</u> -------(ii)   { Now add the two equations}

              - 4d = -64

                   d = -64/-4

                  d = 16

Plug in the value of d in equation (i),

a + 2*16 = 116

a + 32 = 116

        a = 116 - 32

        a = 84

12th term = 84 + 11* 16 = 84 + 176 = 260
