The functions f(x) and g(x) are defined below.
Vilka [71]
So you do g of x first which is root of -4 and then sub that into f of x to get root minus 4 to the power of 4 - 2 root -4 squared + 2 which is the same as (((-4)^1/2)^2) - 4 times -4 + 2 which is the same as -4^2+16 +2 which is the same as 16+16+2 which is 34. Hope this helps :)

A water trough is 7 feet long, and its cross section is an equilateral triangle with sides 4 feet long. Water is pumped into the
Tju [1.3M]

Answer:

a. An equilateral triangle main characteristic is that all the sides lenght are the same (s). To find the height (h), we could divide the triangle (as seen in the picture) and apply Pytagorean theorem.

(\frac{s}{2}) ^{2} +h^{2}=s^{2}

Clearing the expression, we obtain: h= \frac{\sqrt{3}}{2}s

b. Knowing the rate at which the volume is changing 4 ft^{3}, we can find the relation between the change in the volume and the height.

V=A*h

As we want to express the volume in terms of the height, we have to find the area in terms of height

A=\frac{base*height}{2}

Base=s=\frac{2h}{\sqrt{3}}

Therefore, A=\frac{\frac{2h}{\sqrt{3}} *h}{2} =\frac{h^{2} }{\sqrt{3}}

V=7 ft*\frac{h^{2}}{\sqrt{3}}

Therefore the change in the volume with the height, will be the derivate of this expression

\frac{dV}{dt} =2*7*\frac{h}{\sqrt{3}} (\frac{dh}{dt}  )

Knowing dV/dt=4 cubic feet per second, and h=1/2 foot, we can know dh/dt

\frac{dh}{dt}=\frac{\frac{dV}{dt}*\sqrt{3}}{7*2*h} =\frac{4*\sqrt{3} }{14*\frac{1}{2} }=0.98 ft/sec
