Step-by-step explanation:
1. 863 ÷ 33 = 26.15151515
1600 ÷ 26.15151515 ≈ 62
2. 26.15151515 × 1600 ≈ 2144
Answer:
only -2 is in the domain
Step-by-step explanation:
For negative values under the sqrt, there is no real answer, hence
-2x ≥ 0
only for x=-2 this is the case.
The domain represents all the valid input values for x.
Answer:
Step-by-step explanation:
lets remember which are the prime numbers 1 to 81
2,3,5,7,23,29,31,37,....83
the only way you can write 81 as a product of its prime factors are
3x3x3x3=3^4
The bases of triangles are paralleles, so the angles are the same, the sum og the interior angles are always 180° in a triangle, so 180 - 55 -60 = 65°
x = 65°
y = 60°
z = 55°
Answer:
2nd one
Step-by-step explanation:
it's more than 90°
