Answer:
Step-by-step explanation:
x1=9 x2=8 y1=12 y2=11
=x2-x1
y2-y1
=8-91
1-12
=-1
-1
magintude =![\sqrt{(xcomp)^2+(y comp)^2](https://tex.z-dn.net/?f=%5Csqrt%7B%28xcomp%29%5E2%2B%28y%20comp%29%5E2)
=![\sqrt{(-1)^2+(-1)^2](https://tex.z-dn.net/?f=%5Csqrt%7B%28-1%29%5E2%2B%28-1%29%5E2)
=![\sqrt{1+1](https://tex.z-dn.net/?f=%5Csqrt%7B1%2B1)
=![\sqrt{2](https://tex.z-dn.net/?f=%5Csqrt%7B2)
direction=y component/x component
tan=-1/-1
tan=1
1=45
=45 degree
both x component and y component are negative so it lies on third quadrant.
Answer:
81
Step-by-step explanation:
93-12=81
To solve these you have to follow the orders of operation(BEDMAS), which means brackets, exponents, division, multiplication, addition, subtraction all in that order.
A) This is false. 7x6+4=46 and does not equal 7x10 or 70.
B) This is false as well. The answer haste be 19 and 16-(4+7) does not equal 19. You add up what is in the brackets first and then subtract.
This means that C and D have to be true.
C) 10+(6/3)=12
10+2=12 True
D) 2+5x7=37
2+35=37
Also true
Therefore, the length of the median from B is 5/2 cm.
Answer:
Answer D
Step-by-step explanation:
You can see that AC belongs to both triangles (ABC and CDA), you AC is the common side.
