Find the 10th and nth term of each G.P.:5,25,125,.....

RUDIKE [14]

Answer:

The $n^{th}$ of the sequence

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

The $10^{th}$ of the sequence

$t_{10} = 5(5)^{10-1} = 9,765,625$

Step-by-step explanation:

Explanation:-

Given that the geometric sequence

5, 25 , 125 ,....

First-term a= 5

Difference $r = \frac{25}{5} =5$

The $n^{th}$ of the sequence

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

The $10^{th}$ of the sequence

$t_{10} = 5(5)^{10-1} = 9,765,625$

What are the solutions of each equation? a. x2 + 4 = 4 b. x2 + 16 = 0 c. x2 − 49 = 0

OLga [1]

Answer:

a. x=0

b x=-8

c x=49/2

Step-by-step explanation:

a. x2+4=4

subtract 4 from both sides

x2=0

multiply

2x=0

divide by 2

x=0

b x2 + 16 = 0

multiply

2x+16=0

subtract both sides by 16

2x=-16

divide by 2

x=-8

c x2 − 49 = 0

multiply

2x-49=0

add 49 to both sides

2x=49

divide both sides by 2

x=49/2
