Answer:

176.58 m/s

Step-by-step explanation:

assume that the acceleration due to gravity, g = 9.81 m/s²

I also assume we neglect air resistance (hence we assume no terminal velocity)

recall that one of the equations of motions can be expressed as

v = u + at, where

u = initial velocity = 0 (because it says you started from rest)

v = final velocity (we are asked to find this)

a = acceleration due to gravity = 9.81 m/s²

t = time = given as 18s

simply substitute the above into the equation.

v = 0 + (9.81)(18)

v = 176.58 m/s

Ten individuals are candidates for a committee. Two will be selected. How many different pairs of individuals can be selected?
Nina [5.8K]

Answer:

45

Step-by-step explanation:

The different pairs of individual can be computed using rule of combination.

The combination is denotes as nCr.

nCr=n!/(r!(n-r)!)

In the given problem n=total candidates=10 and r= Selected candidates=2.

10C2=10!/(2!(10-2)!)

10C2=10*9*8!/(2!8!)

10C2=90/2

10C2=45

So, 45 different pairs of individuals can be selected.

Expanded notation can be defined as to rewrite the numbers to show their place values

For example in the given question 3 is at the tenth thousand place, 1 is at the thousand'th place,8 at tenth and 4 at unit place so the solution for the question is given below:

30000+1000+80+4+0.5

lesya [120]

Answer:

690%

Step-by-step explanation:

To find the percent increase, take the new amount and subtract the original amount

5600000-80000=5520000

Divide it by the original amount

5520000/800000

6.9

Multiply this by 100% to change from decimal form to percent form

6.9*100%

690%
