What is the value of the fourth term in a geometric sequence for which a1 = 30 and r= 1/2

Tcecarenko [31]

Answer:

3¾

Step-by-step explanation:

Geometric sequence also known as geometric progression, can be said to be a sequence with a constant ratio between the terms.

Formula for geometric sequence:

$a^n = a ( n-1 ) * r$

Given:

First term, a1 = 30

ratio, r = ½

Required:

Find the fourth term

Where, the first term, a¹ = 30

Second term: a² = 30 * ½ = 15

Third term: a³ = 15 * ½ = 7.5

Fourth term: a⁴ = 7.5 * ½ = 3.75 = 3¾

Therfore the fourth term of the geometric sequence is 3¾

If `f(x)=x^2-81` and `g(x)=(x-9)^(-1)(x+9)`, find `g(x)xxf(x)`.

marshall27 [118]

Answer:

$g ( x ) * f ( x ) = ( x + 9 ) ^ 2$

Step-by-step explanation:

We are given the following two functions and we are to find $g(x) * f(x)$ :

$f(x)=x2-81$

$g(x)=(x - 9)^{-1} ( x + 9)$

$g(x)*f(x)=x^{-81} * \frac{x+9}{x-9}$

$g ( x ) * f ( x ) =\frac{(x+9)(x-9)(x+9)}{x-9}$

$g ( x ) * f ( x ) = ( x + 9 ) ( x + 9 )$

$g ( x ) * f ( x ) =( x + 9 ) ^ 2$

1. Jin bought 3 small candles and 1 medium candle for $3.85. Trish bought 4 small candles and 5 medium candles for $10.45. Write

Ivanshal [37]

Hi, thank you for posting your question here at Brainly.

Jin: 3 small candles and 1 medium candle
3s + 1m = 3.85 <-- equation 1

Trish: 4 small candles and 5 medium candles
4s + 5m = 10.45 <-- equation 2

Solving the system of equations,

s = $0.8/small candle
m = $1.45/medium candle
