Mathematics

Answer:

sqrt(1/2x+6) = h^-1 (x)

Step-by-step explanation:

To find the inverse, we exchange x and y and then solve for y

y = 2x^2 -12

Exchange x and y

x = 2y^2 -12

Solve of y

Add 12 to each side

x+12 = 2y^2

Divide by 2

(x+12) /2 = 2y^2/2

(x+12)/2 =y^2

1/2 x+6 = y^2

Take the square root of each side

sqrt(1/2x+6) = sqrt(y^2)

sqrt(1/2x+6) = y

This is the inverse

Aleks [24]

Answer:

x = ± \sqrt{\frac{p}{m} }

Step-by-step explanation:

Given

mx² = p ( divide both sides by m )

x² = \frac{p}{m} ( take the square root of both sides )

x = ± \sqrt{\frac{p}{m} }

Find the approximate value of √191 to the nearest tenth. What 2 numbers does it fall between when placed on a number line?
meriva

The approximate value of √191 to the nearest tenth is 13.8 and the two numbers that should fall on the number line is between 13-13.5.

Given that,

  • The square root of √191.

So, the approximate value of √191 is

= \sqrt{191} \\\\= 13.82\\\\

= 13.8

It shows that the two numbers that should fall between at the time when place on the number line is between 13-13.5.

Therefore we can conclude that the approximate value of √191 to the nearest tenth is 13.8 and the two numbers that should fall on the number line are between 13-13.5.

You want to draft a four ­player tennis team. There are eight players to choose from. How many different teams can you form?
Butoxors [25]

We want to make a 4 players team, and there are total 8 players. As we know the order of selection does not matter in a team of players, only the combination of players matters.

So we would use concept of Combinations and It will be choose 4 out of 8 players.

The formula for Combination is given as follows :-

nCr = \frac{n!}{r!*(n-r)!} \\\\&#10;Choose \;4 \;out \;of \;8 \;players \\\\&#10;8C4 = \frac{8!}{4!*(8-4)!} = \frac{8!}{4!*4!} \\\\&#10;8C4 = \frac{8*7*6*5*4*3*2*1}{(4*3*2*1)*(4*3*2*1)} = \frac{8*7*6*5}{4*3*2*1} =\frac{1,680}{24} = 70 \;combinations

Hence, Total number of different teams = 70 combinations.
