Step-by-step explanation:

$-3x+b=4$

$\implies{-3(2)+b=4}$

$\implies\sf\blue{-6+b=4}$

$\implies\sf\green{b=4+6}$

$\implies\sf\purple{b=10}$

Answer:

Maximum Volume = 29,659.5 cubic inches

Step-by-step explanation:

We can write the perimeter as 2*(x+h) and this is equal to 117

$2(x+h) = 117\\x+h=58.5\\h=58.5-x$

The volume is $x^2(h)$

Plugging the expression for h, we have:

$V=x^2 h\\V=x^2(58.5-x)\\V=58.5x^2-x^3$

The max volume can be found when this differentiated is equal to 0, or dV/dx=0

$V=58.5x^2-x^3\\\frac{dV}{dx}=117x-3x^2=0\\3x(39-x)=0\\x=0,39$

x can't be 0, so we take x = 39

and thus h=58.5-x = 58.5-39=19.5

Max Volume = $x^2h=(39)^2 (19.5)=29,659.5$

MAXImum [283]

Well there is no following but I can tell you that the probability of getting tails is 48/100 which they probably want simplified which jusst means divide both numerator and denominator(top and bottom numbers) by Z (whatever number works) untill it can't be a whole number anymore(a number without a decimal number), simply put, divide top and bottom numbers by the GCM(Greatest Common Multiple) which in this case is 4. 48/4=12, 100/4=25 48/100=12/25 you can't simplify that any more so the answer is 12/25

The Answer Is 12/25 or 48%

Hope This Helps.
