The infinite sequence $T=\{t_0,t_1,t_2,\ldots\}$ is defined as $t_0=0,$ $t_1=1,$ and $t_n=t_{n-2}+t_{n-1}$ for all integers $n&g

katrin [286]

$t_n$ are the Fibonacci numbers,

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...

Taken modulo 7, we get the sequence

0, 1, 1, 2, 3, 5, 1, 6, 0, 6, 6, 5, 4, 2, 6, 1, ...

that repeats with period 16 (this is known as the 7th Pisano period).

This is to say,

$t_a\equiv t_{16n+5}\equiv t_5\equiv5\pmod7$

$t_b\equiv t_{16n+10}\equiv t_{10}\equiv6\pmod7$

$t_c\equiv t_{16n+15}\equiv t_{15}\equiv1\pmod7$

so that

$(t_a+t_b+t_c)\equiv(5+6+1)\equiv\boxed5\pmod7$

Answer:

F= G m₁m₂/r²

a. F is directly proportional to the masses so any increase in the masses will increase the Force F and vice versa.

b. F is inversely proportional to the square of the distance between the masses so any increase in the distance will decrease the force F and vice versa.

c. G is a gravitational constant and is expressed in Nm²/kg². this will give force in Newtons

Erwin flips a coin and rolls a standard number cube. Find the probability that the coin will show heads and the cube will show a

Tomtit [17]

Answer:

flipping heads on a coin is a 1/2 chance, and multiples of three are 3 and 6, which is 1/3, thus, 1/2×1/3=1/5 there is a 1/5 chance Erwin will flip heads and roll a multiple of 3.
