112
84 times 4/3= 336/3=112
Answer:
Step-by-step explanation:
In the argand plane for plotting points of complex numbers we take i coefficient as x and j coefficient as y and plot as we plot regular points on the graph.
v=3i+2j
Point is (3,2) A
w =2i+3j , Point is (2,3) B
v+w = 5i +5j Point is (5,5) C
2w = 4i+6j , point is (4,6)
v-w = i-j Point (1,-1)
Please find enclosed the above points plotted on the graph.
To get this you would do 8x8 which equals 64
1. 326.73 Its easy, just get the circumference of the circle and multiply it by 9. Then get the area of the circle and multiply that by 2, then add the values together. Cant do 2 or 3 cause I feel like I will get them wrong since I start overthinking it.
