Find the distance between points K(−1, −3) and L(0, 0). Round to the nearest tenth.

Step-by-step explanation:

The formula of a distance between two points (x₁; y₁) and (x₂; y₂):

We have K(-1; -3) and L(0; 0). Substitute:

Look at the picture.

We have the right triangle with the legs 3 and 1.

Use the Pythagorean theorem:

substitute:

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
