Yolanda owns 4 rabbits. She expects the number of rabbits to double every year.
klasskru [66]
It is geometric sequence.
Therefore:
a_1=4\\
q=2\\
S=a_1*\frac{1-q^n}{1-q}\\
64=4*\frac{1-2^n}{1-2}\\
16=\frac{1-2^n}{-1}\\
-16=1-2^n\\
16+1=2^n\\
2^4+1=2^n\\
n>4

After 4 yours she will have over 64 rabbits.

Angle sec0= -13/12 and cot<0. what are the exact values of tan0 and sin0.
Arturiano [62]

Answer:

tan 0= -2.4

sin 0 = 0.42

Step-by-step explanation:

sec 0 = -13/12 => cos 0 = -12/13

cot 0 < 0 => tan 0 < 0

so, the angle is on second quadrant

=> tan 0 = -12/5 = -2.4

=> sin 0 = 5/12 = 0.42
