Nolan used the following procedure to find an estimate for StartRoot 18 EndRoot. Step 1: Since 4 squared = 16 and 5 squared = 25 and 16 < 18 < 25, StartRoot 18 EndRoot is between 4 and 5. Step 2: Since 18 is closer to 16, square the tenths closer to 4. 4.1 squared = 16.81 4.2 squared = 17.64 4.3 squared = 18.49 4.4 squared = 19.36 Step 3: Since 18.49 rounds to 18, 4.3 is the best approximation for StartRoot 18 EndRoot. In which step, if any, did Nolan make an error?

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

i did it myself and i got 4.2 (b) hope its right

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
