Find the 10th term of the geometric sequence 1, 3, 9, ...

Mathematics
1 answer:
ladessa [460]2 years ago
3 0

Answer:

a(10) = 3^9 = 19683

Step-by-step explanation:

In this sequence each new term is equal to 3 times the previous term.  Thus, 3 is the common ratio.  The first term is 1.

The general formula for the nth term of a geometric sequence i

a(n) = a(1)*r^(n -1), where r is the common ratio.

Here, a(n) = 1*3^(n - 1), and so

the 10th term is

           a(10) = 1*3^(10 - 1), or

            a(10) = 3^9 = 19683

Solve for x. 3x/4 - X/12 =7/8 simplify your answer in fraction form ​
Usimov [2.4K]

Answer:

7/3

Step-by-step explanation:

or, 3x/4 - 7/8 = 7/8

or, 3x/4=7/8+7/8

or, 3x/4 = (7+7)/8

or, 3x/4 = 14/8

or, 3x = (14/8)*4

or, 3x=56/8

or, 3x= 7

or, x=7/3

The area of the front side of the toy building is 1 square foot. The real building's
Brilliant_brown [7]
The ratio or the relationship of the toy to the large building is one foot to every 400 feet so in mathematical terms it’s shown as a ratio like this... 400:1 and since they are asking about the real building as the primary reason for the ratio it’s number goes first because they are enquiring about it’s relationship to the small one.(which is worded weirdly so I think they are trying to get you messed up)
Good luck

Find the value of x. Express your answer in simplest radical form
klemol [59]
Since x=x, this is an isosceles right triangle.  By the Pythagorean Theorem:

h^2=a^2+b^2  (the hypotenuse squared is equal to the sum of the squared sides)

5^2=x^2+x^2

25=2x^2

2x^2=25

x^2=25/2

x=√(25/2)

x=5/√2  now if we rationalize the denominator...

x=(5√2)/(√2√2)

x=(5√2)/2

Graph the function defined by f(x) = (x+21)
Inga [223]

Answer:

A

Step-by-step explanation:

Consider the parent function y=|x|. The graph of this function is represented as red graph in attached diagram.

Now consider the function y=|x+2|.

Remind main translations of the graph of the function y=f(x):

  • y=f(x-a) - translation a units to the right;
  • y=f(x+a) - translation a units to the left;
  • y=f(x)+a - translation a units up;
  • y=f(x)-a - translation a units down.

In your case, the graph of the function y=|x+2| is translated graph of the function y=|x| 2 units to the left (blue graph). So, correct answer is option A.
