Sketch the graph of y =sine3x​
IgorLugansk [536]

The graph of \mathbf{y=\sin{3x}} is given by,

Here given the function is y=\sin{3x}

when x=0\Rightarrow y=\sin{3\times 0}=\sin0=0, then it passes through the origin (0,0).

When x=\frac{\pi}{6}\Rightarrow y=\sin{3\times\frac{\pi}{6}}=\sin\frac{\pi}{2}=1

Since we know that, -1\leq\sin{x}\leq1,\forall x, then the function has maximum height at x=\frac{\pi}{6}.

Again when x=\frac{\pi}{3}\Rightarrow y=\sin{(3\times\frac{\pi}{3})}=\sin\pi=0, again the function is 0.

So clearly the function is the Oscillating function.

Using graphing calculator we get the graph of function y=\sin3x,

An inverted pyramid is being filled with water at a constant rate of 25 cubic centimeters per second. The pyramid, at the top, h
UNO [17]

Answer:

\frac{225}{16} cm/s

Step-by-step explanation:

We are given that

\frac{dV}{dt}=25cm^3/s

Side of base=4 cm

l=w=4 cm

Height,h=12 cm

We have to find the rate at which the water level rising when the water level is 4 cm.

Volume of pyramid=\frac{1}{3}lwh=\frac{1}{3}l^2h

\frac{l}{h}=\frac{4}{12}=\frac{1}{3}

l=\frac{1}{3}h

Substitute the value

V=\frac{1}{27}h^3

Differentiate w.r.t t

\frac{dV}{dt}=\frac{3}{27}h^2\frac{dh}{dt}

Substitute the values

25=\frac{1}{9}(4^2)\frac{dh}{dt}

\frac{dh}{dt}=\frac{25\times 9}{16}=\frac{225}{16} cm/s
