If x - 4 , x + 2 and 3x + 6 form a geometric sequence, find x.
Alex17521 [72]

Answer:

x =7

Step-by-step explanation:

Remark

  • A geometric sequence always has terms that are separated by a common ratio. For example 3 9 27 81 243 ....
  • Each term is multiplied by a common number and the term before it. In this case the common term is 3.
  • To get the next term after 9, you multiply 9 by 3.
  • To get the common ratio divide the second term by the first and then the third term by the second

Equation

(x + 2)/(x - 4) = (3x + 6)/ (x + 2)

Solution

I would begin this problem by taking out the common factor on the top right term. You'll see why in a second.

(x + 2)/(x - 4) = 3(x + 2)/ (x + 2)   Notice the two binomials on the right cancel.

  • (x + 2)/(x - 4) = 3/1                       Cross multiply
  • (x + 2)*1 = 3*(x - 4)                       Remove the brackets on the right.
  • x + 2 = 3x - 12                             Add 12 on both sides.
  • x + 2 + 12 = 3x - 12 + 12              Simplify
  • x + 14 = 3x                                  Subtract x from both sides
  • 14 = 3x - x
  • 2x = 14                                        Divide by 2
  • x = 14/2
  • x = 7

The track and field coach records Ian's 400-meter race times during three practices. How much greater was the percent of change
BigorU [14]

Answer:

d.  1.5%

Step-by-step explanation:

Given - The track and field coach records Ian's 400-meter race times during three practices.

Practice        1          2           3

Time (s)         63       60        58

To find - How much greater was the percent of change from Practice 1 to Practice 2 than from Practice 2 to Practice 3? Round to the nearest tenth.

a. 7.9%

b.  4.8%

c.  3.3%

d.  1.5%

Proof -

% change from Practice 1 to Practice 2 change = \frac{60 - 63}{63}. 100%

                                                                           = -\frac{3}{63}.100% = - 4.761904762 %

⇒% change from Practice 1 to Practice 2 change = - 4.762 %

Now,

% change from Practice 2 to Practice 3 change = \frac{58 - 60}{60}. 100%

                                                                           = -\frac{2}{60}.100% = - 3.334 %

⇒% change from Practice 2 to Practice 3 change = - 3.3334 %

So,

- 4.461904762% - (- 3.3334%) = -4.461904762 + 3.3334 % = -1.4285 % ≈ 1.5%

∴ we get

Value = 1.5%

The correct option is - d.  1.5%
