Answer:

The 8th term of the following sequence is 9375.

Step-by-step explanation:

Given the sequence

3/25, 3/5, 3, 15

As we know that a geometric sequence has a constant ratio and is defined by:

\:a_n=a_0\cdot r^{n-1}

so

\frac{3}{25},\:\frac{3}{5},\:3,\:15

\frac{\frac{3}{5}}{\frac{3}{25}}=5,\:\quad \frac{3}{\frac{3}{5}}=5,\:\quad \frac{15}{3}=5

As the ratio 'r' is the same.

so

r=5

As the first element of the sequence is

a_1=\frac{3}{25}

Therefore, the nth term is computed by

\:a_n=a_0\cdot r^{n-1}

a_n=\frac{3}{25}\cdot \:5^{n-1}

Putting n = 8 to determine the 8th term.

a_8=5^7\cdot \frac{3}{25}

a_8=\frac{3\cdot \:5^7}{25}

    =\frac{5^7\cdot \:3}{5^2}

     =5^5\cdot \:3

     =9375

     

Therefore, the 8th term of the following sequence is 9375.

Delvig [45]

Answer:

f = 2x + 24/ 3

Step-by-step explanation:

Step 1: Divide both sides by x.

fx/x = 2/3 x^2 + 8x/x

f = 2x + 24/3

(2x + 3y) + (4x - 3y) = 11+(-5)
Maurinko [17]

Answer:

The correct option should have been 6x=6.

Step-by-step explanation:

Given the expression

\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)

solving the expression

\left(2x\:+\:3y\right)\:+\:\left(4x\:-\:3y\right)\:=\:11+\left(-5\right)

Remove parentheses:  (a) = a

2x+3y+4x-3y=11-5

Group like terms

3y-3y+2x+4x=11-5

Add similar elements

6x=6

It is clear that not a single given option is 6x=6. It means no option is correct. It seems you mistyped the correct options.

The correct option should have been 6x=6.
