This is multiplying an even number of negatives together so the answer will always be positive
Answer:
Step-by-step explanation:
<h3>To prove quadrilateral is a square:</h3>
a) Slope of CB
C(-3,-1) ; B = (0,3)
b) D(1,-4) ; A(4,0)
Slope of CB = slope of DA
c) C(-3,-1) ; D(1 , -4)
So, CD is perpendicular to CB
d) B(0,3) ; D(1,-4)
e) C(-3,-1) ; A(4,0)
So, CA is perpendicular to BD
Ok. I do though, good luck
Answer:
5
Step-by-step explanation:
13u - 8u = 25
5u = 25
u = 5
Answer: 1.1 Nm
Step-by-step explanation:
The formula for torque is T = r · F · sin θ
where θ = π/6, r = 20 cm = 0.2 m, F = 11 N
formula for converting radians to degrees is 1 rad × 180/π = 57.296°
θ = π/6 · 180/π = 30°
Substituting r into the formula for torque, we have
T = 0.2 x 11 x sin 30° = 0.2 x 11 x 0.5
T = 1.1 Nm
