you increase your walking speed from 1 m/s to 3 m/s in a period of 1 s. What is your acceleration? A) 2 m/s ^2 B) 3 m/s ^2 C) 5

arsen [322]

Acceleration is to change in speed divided by the time for the change. Change in speed is end speed minus started speed.

3m/s-1m/s and equals to 2m/s.

The answer should be A. (2m/s^2.)

Hope it helped you!

Have a great day!

Find an inverse of 16 modulo 17. That is solve 16x=1(mod 17)

mote1985 [20]

Answer:

-1 is the inverse of 16 modulo 17.

Step-by-step explanation:

To find : An inverse of 16 modulo 17 i.e. $16x=1(mod 17)$ ?

Solution :

First we find the GCD of (17,16) using Euclid's algorithm,

$17=16\times 1+1$

Remainder is 1.

Which means, GCD(17,16)=1

Using back substitution we get,

$1=17-16(1)$

$\Rightarrow 16(-1)=1+17(-1)$

$\Rightarrow 16(-1)=1(\mod 17)$

i.e. -1 is the inverse of 16 modulo 17.

On comparing with $16x=1(mod 17)$

The value of x=-1.
