Answer:
Isosceles trapezoid
Step-by-step explanation:
Plotting the points show us that this shape is at least a trapezoid, by the fact that only one pair of parallel sides.
To show that it is isosceles is done by finding the lengths of the diagonals, which takes quite long, but here, it is very clear that the two non-parallel sides are congruent, and the parallelogram is perfectly symmetrical.
B. 8 the radius is half the diameter
Yeah, I agree with letsgoplayd. Your answer doesn't make any sense because 8164 is not a decimal. But we can look at another example:
8164.45678
In this case, the number rounded to the 4th decimal point (ten thousandths) would be
8164.45680
Because the digit after the 7 is 8, we should round the "78" part to "80".
These two rules will help:
5 or more, raise the score (add 1 to the digit, and let the digit directly behind it become 0.)
4 or less, let it rest (keep the digit, and let the digit directly behind it turn to a 0.)
Hope this helps! :)
