(-3,4)(-6,-1)
The easy way
look at the y's = 4 and -1 the difference is 5 now /2 = 2.5
so the y midpoint is 2.5 from each point or 1.5
look at the x's = -3 and -6 the differebce is 3 now /2 = 1.5
so its 1.5 from each point or -4.5
so midpoint is (-4.5, 1.5) or (-9/2, 3/2) or C
the formula way:
for x
x1+x2/2
-3+-6/2
-9/2 (which is -4.5)
for y
y1+y2/2
4+-1/2
3/2 (which is 1.5)

Answer:
- 2nd force: 99.91 lb
- resultant: 213.97 lb
Step-by-step explanation:
In the parallelogram shown, angle B is the supplement of angle DAB:
∠B = 180° -77°37' = 102°23'
Angle ACB is the difference of angles 77°37' and 27°8', so is 50°29'.
Now, we know the angles and one side of triangle ABC. We can use the law of sines to solve for the other two sides.
BC/sin(A) = AB/sin(C)
AD = BC = AB·sin(A)/sin(C) = (169 lb)sin(27°8')/sin(50°29') ≈ 99.91 lb
AC = AB·sin(B)/sin(C) = (169 lb)sin(102°23')/sin(50°29') ≈ 213.97 lb

<h3>
Answer:</h3>
4.42×10^34 molecules/min
<h3>
Step-by-step explanation:</h3>
Multiply the various factors, along with the unit conversion (60 s/min).
... (3.35×10^25 molecules/L) × (2.2×10^7 L/s) × (60 s/min)
... = (3.35×2.2×60)×10^(25+7) molecules/min
... = 442.2×10^32 molecules/min
... ≈ 4.42×10^34 molecules/min
