-21x^3 - 8x^3 = -29x^3
-7/4x^(1/2) - 0 = -7/4x^(1/2)
-6x^(1/4)
-12x^(-1/2)
12x^(-1/4)
14x^4
Therefore, the correct option is the 2nd one.
He is overestimating because 2.25 * 6 = 13.5, which is less than 11.5
Answer: THanks
Step-by-step explanation:
12, 13, 15, 20, 24, 25, 26, 31, 33, 34
First, let's just find everything (minimum, maximum, Q₁, median {Q₂}, Q₃)
Minimum : 12, because it is the lowest number.
Maximum : 34, because it is the highest number.
Median (Q₂) : 24.5, because it is the middle number.
Q₁ : 15, because it is between 24.5 and 34
Q₃ : 31
So,
1) d-12
2) c - 34
3) b-15
4) f-24.5
5) a-31

Medida do angulo central = medida do arco interceptado
arco = 25º e ângulo central = 25º
