Start with

$\dfrac{1}{\sin^2(x)}=4$

Invert both sides:

$\sin^2(x) = \dfrac{1}{4}$

Consider the square root of both sides with double sign:

$\sin(x) = \pm\sqrt{\dfrac{1}{4}} = \pm\dfrac{1}{2}$

We have

$\sin(x) = \dfrac{1}{2} \iff x = \dfrac{\pi}{6}\ \lor\ x = \dfrac{5\pi}{6}$

and

$\sin(x) = -\dfrac{1}{2} \iff x = \dfrac{7\pi}{6}\ \lor\ x = \dfrac{11\pi}{6}$

Match each exponential function to the description of its percent rate of change.

dolphi86 [110]

Answer:

Given in order:

22% growth
12% growth
12% decay
20% decay

Step-by-step explanation:

The exponential function is in the form $f(x)=a(1+r)^x$

If r is positive (the number in the bracket is larger than 1), then it is exponential growth and if r is negative (the number in the bracket is less than 1), then it is exponential decay.

Growth or Decay by how much???

The amount that is greater than/less than 1

The first function's number inside the bracket is greater than 1 by 0.22 (22%). So it is "22% growth".
The second function's number inside the bracket is greater than 1 by 0.12 (12%). So it is "12% growth".
The third function's number inside the bracket is less than 1 by 0.12 (12%). So it is "12% decay".
The fourth function's number inside the bracket is less than 1 by 0.2 (20%). So it is "20% decay".
