36 = 3^2 * 2^2
Can you follow me and like me please? I hope i can help you more.☺
|AD|=(3i-1j)-(-3i-0j)=3i-1j+3i+0j=6i-1j
|BA|=(-3i-0j)-(-1i+3j)=-3i-0j+1i-3j=-2i-3j
Area =|AD|x|BA|
= i j k
6 -1 0
-2 -3 0
= -1 0 i - 6 0 j + 6 -1 k
-3 0 -2 0 -2 -3
= 0 i - 0 j + (-18-2)k = -20 k
√(-20)² =20
The answer is A (3). In the question you are given a list of numbers, these are the results from the science project. In the list, the number 12 appears 5 times, therefore 5 dots are added above the number 12 on the dot plot. 11 appears once, 13 appears 3 times, 14 appears 3 times and 15 appears three times. Hope this helps.
The answer is (5, -8) Hope I helped :)
