A) If the 5th term of an A.P. is double the 7th term, show that the sum of the 17 terms zero.​
gayaneshka [121]

Answer:

see explanation

Step-by-step explanation:

The nth term of an AP is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₅ is double a₇ , then

a₁ + 4d = 2(a₁ + 6d) , that is

a₁ + 4d = 2a₁ + 12d ( subtract a₁ from both sides )

4d = a₁ + 12d ( subtract 12d from both sides )

- 8d = a₁

The sum of n terms of an AP is

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ] , substitute values

S_{17} = \frac{17}{2} ( 2(- 8d) + 16d)

     = 8.5(- 16d + 16d)

     = 8.5 × 0

     = 0

What is this math problem x²+9×+14=0
WINSTONCH [101]
x^2+9x+14=0\\\\ x_{1}=\frac{-b-\sqrt{b^2-4ac} }{2a}=\frac{-9-\sqrt{9^2-4*1*14 } }{2 }=\frac{-9-\sqrt{81-56 } }{2 }= \frac{-9-\sqrt{25 } }{2 }=\\\\=\frac{-9-5 }{2 }=\frac{-14 }{2 }= -7\\\\ x_{2}=\frac{-b+\sqrt{b^2-4ac} }{2a}=\frac{-9+\sqrt{9^2-4*1*14 } }{2 }= \frac{-9+5 }{2 }=\frac{- 4 }{2 }= -2

How do I solve f+4/g=6 for f showing my work
V125BC [204]

We have two solutions for this problem based on the given equation.


<u><em>Answer #1:</em></u>

<u>If the given equation was:</u>

f + \frac{4}{g} = 6


To solve for f, we would need to isolate the "f" on one side of the equation.

In case of the above equation, we can simply do that by subtracting \frac{4}{g} from both sides of the equation

<u>This would give:</u>

f + \frac{4}{g} - \frac{4}{g} = 6 - \frac{4}{g}

f = 6 - \frac{4}{g}


<u><em>Answer #2:</em></u>

<u>If the given equation was:</u>

\frac{f+4}{g} = 6


To solve for f, we would still need to isolate the "f" on one side of the equation.

<u>This can be done as follows:</u>

\frac{f+4}{g} = 6 ................> multiply both sides by (g)

f + 4 = 6g ................> subtract 4 from both sides of the equation

f + 4 - 4 = 6g - 4

f = 6g - 4


Hope this helps :)
