Please someone help and explain them to me. im confused

Biologist created the following graph to show the relationship between the temperature of water x, and degrees Celsius, and the

PtichkaEL [24]

There is no graph but if I had to guess then I would go with answer choice C

Hope this helps!

What is the axis of symmetry for f(x) = −3x2 + 12x − 6?

Marta_Voda [28]

The axis of symmetry can be found by finding the average of the zeros, a derivation from the conservation of energy :P, or by finding the point when the velocity is equal to zero.

df/dx=-6x+12 so df/dx, velocity, equals zero when:

-6x+12=0

6x=12

x=2 so the axis of symmetry is the vertical line x=2

....

average of zeros...

3x^2-12x+6=0

x^2-4x+2=0

x^2-4x=-2

x^2-4x+4=2

(x-2)^2=2

x-2=±√2

x=2±√2 so the average of the zeros is obviously 2.

....

conservation of energy

vf-vi=at When vf=0, this is the maximum value for f(x)...

-vi=at, vi=b and a(acceleration)=2a(from quadratic) and t=x

-b=2ax

x=-b/(2a) in this case

x=-12/(2(-3))

x=-12/-6

x=2

The interquartile range of a data set is 10 units. What does this represent?

Reil [10]

The interquartile range is from Q1 to Q3 and to get this you have to subtract Q2 by Q3. The 10 units represent that only 10 units are fit in the given range.

keiko david and tony have a total of 106$ in their wallets. david has $6 less than keiko tony has 2 times what david has. how mu

mafiozo [28]

<h3>Answer:</h3>

Keiko have $31 in her wallet.

David have $25 in his wallet.

Tony have $50 in his wallet.

<h3>Step-by-step explanation:</h3>

Keiko

Let x = the amount in Keiko’s wallet.

David

David has $6 less than Keiko .

x - 6

Tony

Tony has has two times what David has.

2(x - 6)

The total sum of their money = 106

Keiko

x + x - 6 + 2(x - 6) = 106

2x - 6 + 2x - 12 = 106

4x - 18 = 106

4x = 106 + 18

4x /4 = 124/4

x = 31

Therefore Keiko have $31 in her wallet.

David

x - 6

31 - 6 = 25

Therefore David have $25 in his wallet.

Tony

2(x - 6)

2(31 - 6)

2(25) = 50

Therefore Tony have $50 in his wallet.

To check your work out

31 + 25 + 50 = 106
