Step-by-step explanation:
(4,-30) i am not 100% sure about it.
To find the centroid, follow these steps: Step 1: Identify the coordinates of each vertex. Step 2: Add all the x values from the three vertices coordinates and divide by 3. Step 3: Add all the y values from the three vertices coordinates and divide by 3. Would be your answer
Answer:
see below
Step-by-step explanation:
(ii)
Given 4000 seconds to hours you divide the value by 3600 sec
=4000/3600 =1.1111
=1.0 hour (1 significant figure)
(b)
speed = 212 miles/hour
distance= 1 mile
time = distance/speed = 1/212 * 3600 =16.98 seconds
It's very hard to work out on here, but your final answer is x=3.
You can substitute x=3 in for x to test it.
Hope this Helps!
