Answer:
A
Step-by-step explanation:
slope of the given line: -a/b
-4/-2 = 2
realtionship between the slopes of two perpendicular lines:
m = -1/m
slope of the second line
-1/2
line
y-y1 = m(x-x1)
y - 6 = -1/2(x-4)
y = -1/2x + 2 + 6
y = -1/2x +8
10 groups of 3 students = 30
3 groups of 10 students = 30
5 groups of 6 students = 30
6 groups of 5 students = 30
2 groups of 15 students = 30
15 groups of 2 students = 30
140.4 since the sides are equal . Iguess . I did not calculate or anything but mentally
Ans: DG is perpendicular to FG. OC DG Intersects FG to form an acute angle. ODDO intersects FG to form an obtuse angle.
Answer:
202
Step-by-step explanation:
First, we can find the conjugate of (-9 -11i)
Given a complex number a + bi, the conjugate would be a - bi.
So, the conjugate of -9 -11i is -9 + 11i.
Now, we multiply!
(-9-11i)(-9+11i)
This resembles the special product (a+b)(a-b) which multiplies out to a^2 - b^2
To apply this we subtract the square of the second number from the first.
(-9)^2 - (11i)^2
81 - 121i^2
i^2 is -1, so we can substitute it in:
81 + 121 = 202
