What is an equation for the line that passes through the coordinates (2,0) and (0,3)
Vera_Pavlovna [14]
Gradient of line = (change in y)/(change in x) = -3/2
equation of a line = y-y1 = m (x-x1) = y-0 = -3/2(x-2)
y=-3/2x + 3

What is the value of the fourth term in a geometric sequence for which a1 =<br> 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
