Find P 20 of the following arithmetic sequence: 206, 212, 218, 224....

Yanka [14]

Answer:

$p_{20} = 1.25528$

P₀ = 206 and difference d = 6

Step-by-step explanation:

Step(i):-

Given that the arithmetic sequence

206,212,218,224,.....

P₀ = 206 and difference d = 212-206 = 6

The $n^{th}$ term of the sequence

$t_{n} = ar^{n-1}$

Step(ii):-

The $n^{th}$ term of the sequence

$P_{n} = ar^{n-1}$

Put n=20

$P_{20} = 206 ( 6) ^{20-1}$

$p_{20} = 1.25528$

create a perfect square trinomial that can be factored using special patterns. Factor the trinomial and show all work for full c

Lyrx [107]

Answer: $4x^2+12x+9$

Step-by-step explanation:

A perfect square trinomial is written as $ax^2+bx+c$ , where

first term $ax^2$ = square of first term of binomial

second term= $bx$ =twice the product of both terms of binomial.

and third term 'c'=square of last term of binomial

Thus to create a perfect square trinomial put 'a' and 'c' a square number

Let a=4 and c=9

The required trinomial will be

$4x^2+12x+9$

$=(2x)^2+2(2x)(3)+3^2\\=(2x+3)^2.......\text{[using pattern}(a+b)^2=a^2+2ab+b^2]\\=(2x+3)(2x+3)$

What points are solutions to the equation 3x-4y-8=12

ikadub [295]

Answer:

x = 6.67

Step-by-step explanation:

Rewrite the equation:

-4y = -3x +20

y = $\frac{3}{4} x-5$

Find where y = 0

0 = $\frac{3}{4} x -5$

5 = $\frac{3}{4} x$

x = 6.67

Hope it helps! (:
