Which recursive formula can be used to represent the sequence 2,6,10,14,18,...??? Help ASAP!!!!!

WINSTONCH [101]

We have the sequence 2, 6, 10, 14, 18, ... Always 4 being added, so we can say:

The first term is 2. The added is 4, so,

a1 = 2

$a_n=a_{n-1}+4$

Prove:

$a_2=a_{2-1}+4 => a_2=a_1+4=>a_2=2+4=6$

What is the momentum of each hockey player? Hockey player 1 has a mass of 65 kg and a velocity of 3.8 m/s

DaniilM [7]

Answer:

Momentum of hocking player $1:$ $247\ kg\ m/s$

Hockey player $2:$ $=249.4\ kg\ m/s$

Step-by-step explanation:

For first hockey player :

Given that

mass (m) $=65\ kg$

Velocity (v) $=3.8\ m/s$

$p=mv\................(1)$

where $p$ is momentum

put the value in equation (1)

$p=65\times3.8\\\\p=247kg\times m/s$

For second hockey player :

Given that

mass (m) $=58\ kg$

velocity (v) $=4.3\ m/s$

$p=mv\ ...............(2)$

Where $p$ is momentum

put the value in equation (2)

$p=58\times4.3\\p=249.4\ kg\times m/s$

If a substance decays at a rate of 25% every 10 years, how long will it take 512 grams of the substance to decay to 121.5 grams

Juliette [100K]

Answer:

It will take 50 years to decay from 512 grams to 121.5 grams.

Step-by-step explanation:

The decay formula :

$N=N_0e^{-\lambda t}$

where

N= amount of substance after t time

N₀= initial of substance

t= time.

A substance decays at a rate 25% every 10 years.

So, remaining amount of the substance is = (100%-25%)= 75%

$\frac{N}{N_0}=\frac{75\%}{100\%}=\frac{75}{100}=\frac34$ , t= 10

$N=N_0e^{-\lambda t}$

$\Rightarrow \frac {N}{N_0}=e^{-\lambda t}$

$\Rightarrow \frac34 =e^{-\lambda .10}$

Taking ln both sides

$\Rightarrow ln|\frac34| =ln|e^{-\lambda .10}|$

$\Rightarrow ln|\frac34|=-10\lambda$

$\Rightarrow \lambda=\frac{ ln|\frac34|}{-10}$

Now , N₀= 512 grams, N= 121.5 grams, t=?

$N=N_0e^{-\lambda t}$

$\therefore 121.5=512e^{-\frac{ln|\frac34|}{-10}.t}$

$\Rightarrow 121.5=512e^{\frac{ln|\frac34|}{10}.t}$

$\Rightarrow \frac{121.5}{512}=e^{\frac{ln|\frac34|}{10}.t}$

Taking ln both sides

$\Rightarrow ln|\frac{121.5}{512}|=ln|e^{\frac{ln|\frac34|}{10}.t}|$

$\Rightarrow ln|\frac{121.5}{512}|={\frac{ln|\frac34|}{10}.t}$

$\Rightarrow t=\frac{ln|\frac{121.5}{512}|}{\frac{ln|\frac34|}{10}}$

$\Rightarrow t=\frac{10.ln|\frac{121.5}{512}|}{{ln|\frac34|}}$

⇒t=50 years

It will take 50 years to decay from 512 grams to 121.5 grams.

Determine if the functions are even, odd or neither.

marusya05 [52]

I'm pretty sure its neither just substitute the x for -2 and solve. There has to be a consistency in the values 3 times for there to be a pattern.
