Answer:

195

Step-by-step explanation:

To find many play the harp only, we need to get the number of students that said they play the harp.

268 play the harp

73 play the harp and piano

Now since we're only looking for the students that only play the harp, we subtract the number of students who play the harp and piano to the students who play the harp alone.

268 - 73 = 195

So 195 Students play the harp.

[volume of the container]/[volume of tissue box]
volume of container:
V=length×width×height
V=19.5×39×19.5
V=14829.75

Volume of tissue box:
v=6.5×6.5×6.5
v=274.625

Number of tissues in the container:
14829.75/274.625

What are the domain and range of the function f(x)= x^4 -6x^3 -4x^2 54x -45?
Agata [3.3K]
Domain is the numbers you can use
we can use all real numbers for this one

rangge is the numbers we get from inputting the domain

well, this is a 4th degree, so we need to find the minimum,because the leading coefient is positive so it opens up, and as x approaches negative and positive infinity, then f(x) approaches infnity

find minimum
take derivitive
f'(x)=4x^3-18x^2-8x+54
the zeroes are at about -1.652 and 1.9381 and 4.2145
we use a sign chart
the minimum occurs at hwere the derivitive changes from negative to positive
that is at -1.652 and 4.2145
evaluate f(-1.652) and f(4.2145)
f(-1.652)=-110.626
f(4.2145)=-22.124
the least value is -110.626
that is the minimum

so the domain is all real numbers
range is from -110.626 to infinity
