Does the residual plot show that the line of best fit is appropriate for the data?
yes, the points are rising.
yes, the points are all above the x-axis.
no, it follows a pattern.
no, the points are falling.

your question is incomplete, write all the numbers in the sequence that it tells you.  

step-by-step explanation:

answer4 to the second power is 16

and 4 to the third power is 64,

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
