Answer:
C
Step-by-step explanation:
Educated guess
In generation 8 it would have 34 relatives, and in generation 9 it would have 55 relatives.
In the Fibonacci sequence, each term is found by adding the two previous terms together. For generation 8, we would add generation 7 (21) and generation 6 (13); 21+13 = 34. For generation 9, we would add generation 8 (34) and generation 7 (21); 34 + 21 = 55.
The number -5 is anything but natural number.
It is an integer (Z) ,a rational number (Q) and a real number (R) .
Answer:
A) (1 s, 2.3 s)
B) (-4 m/s², 3.8 m/s²)
Step-by-step explanation:
The car's position which is the distance is given by the equation;
s(t) = t³ - 5t² + 7t
A) Velocity is the first derivative of the distance. Thus;
v(t) = ds/dt = 3t² - 10t + 7
At v = 0, we have;
3t² - 10t + 7 = 0
Using quadratic formula, we have;
t = 1 and t = 2.3
Thus, time at velocity of 0 is t = (1 s, 2.3 s)
B) acceleration is the derivative of the velocity. Thus;
a(t) = dV/dt = 6t - 10
At velocity of 0, we got t = 1 and t = 2.3
Thus;
a(1) = 6(1) - 10 = -4 m/s²
a(2.3) = 6(2.3) - 10 = 3.8 m/s
Thus, a(t) at v = 0 gives; (-4 m/s², 3.8 m/s²)
