Answer:
Step-by-step explanation:
1) 6 tan2x − 6 tan2x sin2x
=
2) 
3) 
4) x=6cos t
So cost =x/6
so -3sint
5)
11. Because 11 x 11 is equal to 121.
6v+4w-4
Because you do -*-6v=positive 6v then -*-4w=positive 4w and then -*4=-4 and that takes care of the parenthesis
Basically you multiply the outside number or sign by all things inside the parenthesis
So in this problem you multiplied the negative sign by all the things inside the parenthesis
Answer:
D.) AB≅A′B′, ∠A≅∠A′, and ∠C≅∠C′
Step-by-step explanation:
<u>Option A</u> identifies two sides and the angle not between them. The two triangles will be congruent in that case <em>only if the angle is opposite the longest side</em>, which is <u>not true</u> in general.
<u>Option B</u>: same deal as Option A.
<u>Option C</u> identifies three congruent angles, which will prove the triangles <em>similar, but not necessarily congruent</em>.
<u>Option D</u> identifies two angles (sufficient for similarity) and one side, sufficient (with similarity) for congruence. The applicable congruence theorem is AAS.
Assuming the wire starts at x=0, the first point is (0,-4) since using y = 3x - 4 :
3(0) - 4 = -4
the two points are (0,4) and (-3,4)
since the y values are the same, the distance is the positive difference between the x values:
-3 - 0 = -3
then,
the distance is 3 meters
each meter costs $125, so multiply the cost by the amount of meters to find the total:
125 x 3 = 375
the total cost is $375
