Answer: They are not perpendicular because their slopes are not negative reciprocals.
Step-by-step explanation:
For these two lines to be perpendicular, their slopes have to be negative reciprocals.
Slope of FG.
F = (-4, 1)
G = (0, -2)
= (Y₂ - Y₁) / (X₂ - X₁)
= (-2 - 1) / (0 + 4)
= -3/4
Slope of HJ
J = (0 , 4)
H = (-4, -2)
Slope = (Y₂ - Y₁) / (X₂ - X₁)
= (-2 - 4) / (-4 -0)
= 6/4
= 3/2
<em>The slopes of these lines are not negative reciprocals so these lines are not perpendicular. </em>

The answer is C, 220 units.
Answer:
The total of the sales price and sales tax is $ 588.35 .
Step-by-step explanation:
As given
$543.51 be the subtotal .
8.25% is the sales tax .
8.25% is written in the decimal form.
= 0.0825
Sales tax price = 0.0825 × 543.51
= $ 44.84 (Approx)
Total of sales price with sales tax = Sale price + Sales tax price
Putting the values in the above
= $543.51 + $44.84
= $ 588.35
Therefore the total of the sales price and sales tax is $ 588.35 .
(sqrt2 - sqrt6)/4 = - 0.259
cos ((7pi)/12) = cos 105 = - 0.259
(√10)/(√3)*(√3)/(<span>√3); multiplied by the conjugate which is = (</span><span>√30/3)</span>
