Answer:
0.47
Step-by-step explanation:
f(x) = (x - 2)^(1/3)
average rate of change from x = -2 to x = 4 is [f(4) - f(-2)]/[4 - (-2)]
f(-2) = (-4)^(1/3) = -1.587401
f(4) = 2^(1/3) = 1.25992
[f(4) - f(-2)]/[4 - (-2)] = [1.25992 - (-1.587401)]/[4 - (-2)] = 0.47
Irrational roots occurs with its conjugate.
Therefore, -√3 is also root of the function.
The answer is -√3.
Answer:
Option B
Step-by-step explanation:
Not a unique triangle—the 10 cm side can be any of the three sides.
Red : Black : Total
7 : 2 : 7+2
7 : 2 : 9
9x = 54
1x = 54÷9 = 6
7x = 7x6 = 42
2x = 2x6 = 12
Red : Black
42 : 12
42 - 12 = 30
There are 30 more red than black
