yea me too

Step-by-step explanation:

V≈18.85 in³

V=π²r*h/3

B

Step-by-step explanation:

So, basically you just need to simplify the answers and see which one simplifies to -3/4^4

so, -3/4 as a decimal is -.75 you would then bring that to the 4th power, you get -.3164...

if you plug the answers into a calculator you will find that answer B will be the correct answer because it equates to -.3164

The answer is -0.5

Step-by-step explanation:

Divide both side by the numeric factor on the left side then solve

n = 5

Step-by-step explanation:

5 * (n/5) = 5 / (n/5)

(5 * n) /5 = 5 * (5/n)

n = ( 5*5) / n

n = 25/n

n² = 25

n = 5

If i'm mistaken; he needs to buy 3 sheets?

The answer to this problem is X= -1/2, -11/2

I think it’s if you multiply the length and width then u get the area 36

I don't know how to do it except for with deritivies

so take the deritivieve and find where the deritivieve equals 0

that is where the sign changes

where the sign changes from (+) to (-), that is max

so

A.

max revenue

R'(x)=[tex]\frac{0-(2x-12)(125)}{(x^2-12x+61)^2}= \frac{1500-250x}{(x^2-12x+61)^2}[/tex]

find where numerator is 0

at x=6

to find change of sign, evaluate the denomenator at above and below 6 and see sign

R'(5)=(+)

R'(7)=(-)

at x=6, the sign changes from (+) to (-)

max is at x=6

sub 6 for x in the R(x) function

R(6)=9 (it's in thousands so $9000 is te max revenue)

B.

max profit

combine them

P(x)=R(x)-E(x)

take the deritive of P(x)

using sum rule

P'(x)=R'(x)-E'(x)

we already know what R'(x) is

E'(x)=[tex]\frac{1}{ \sqrt{2x+1} }[/tex]

P'(x)=[tex]\frac{1500-250x}{(x^2-12x+61)^2}-\frac{1}{ \sqrt{2x+1} }[/tex]

find zeroes or what value of x make P'(x) equal to 0

[tex]\frac{1}{ \sqrt{2x+1} }= \frac{1500-250x}{(x^2-12x+61)^2}[/tex]

use calculator or something or work it out to find x

at x=5.225

x is hundreds so times 100

522.5

about 523 items

A. $9000

B. 523 items
