Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0

Discriminant = 4 - 4(K)(-1) = 4 + 4K

For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.

The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.

Is second term of a geometric series is 48 and it's fifth term is 6 then find the sum of the first 6 terms.

AlekseyPX

Answer:

the sum of the first 6 terms =189

Step-by-step explanation:

the first 6 terms-

96,48,24,12,6,3

I found them easily by dividing 48 with random small numbers until I got 6 for the fifth term. So here I divided 48 by 2 which is = 24(3rd term), then divided 24 by 2 which is =12(4th term) and then again decide the answer by 2 and finally got 6 for the 5th term. So the ratio is 1/2. For the first term I did the opposite, multiply 48 by 2 which is = 96. And lastly find the sixth term and add them up which is = 189

I tried my best to explain it in simple terms, hope this helps:)

Plz help stuck on the question

The length of the rectangle is n-3, ok, the width is 2

the area of a rectangle is just length * width

$\bf A=(n-3)(2)\implies \boxed{A=2n-6}
\\\\\\
\textit{to make some equivalent, let's use our good friend Mr 1}
\\\\\\
\textit{recall that }\cfrac{whatever}{whatever}=1\qquad \qquad \cfrac{same}{same}=1
\\\\\\
\cfrac{55}{55}\cdot 2n-6\implies \cfrac{55(2n-6)}{55}\implies \cfrac{110n-330}{55}
\\\\\\
or
\\\\\\
\cfrac{xyz}{xyz}\cdot 2n-6\implies \cfrac{xyz(2n-6)}{xyz}\implies \cfrac{2nxyz-6xyz}{xyz}$

so, if you simplify either of those, you'd end up with 2n-6.

because same/same = 1, and 1 * anything, is just anything itself.
